Extension of a veranda to a sloping roof. Extension to a wooden house: projects, photos and advice from professionals

Are you here: What to make from drywall

To make the house more original appearance very often they use additional building elements - extensions that will allow you to spend leisure time or gather your family around a large dining table. The extension can be created during the construction of the house or upon its completion. Also, very often a veranda, terrace or other type of extension is used for houses that were built a long time ago. In this case, you will have to think about how to protect the additional room from the influences of nature, its vagaries in the form of snow or rain.

The roof of such a structure must be adjacent to the house and have a certain angle of inclination so that precipitation does not accumulate on its surface. For a long service life of the extension roof, you must carefully follow all the rules and conditions and select the optimal material for the roof.

Types of roofs and types of roofs

A well-thought-out exterior of a private house will create a pleasant impression both for the home owner and for his friends or neighbors, because the external perception of the house determines an opinion about its owner. Ideally, the design of the house and the extension should match each other and fit together correctly.
To make this possible, it is necessary to use a single roofing material, both for the house and for the extension to it. An exception to the rule will be glass extensions for dining table overlooking environment or a greenhouse. In this case, the roof should also have a transparent appearance, regardless of the house and its covering.
It is necessary to understand the specifics of the words, to understand their essence, since the roof is the upper part of the house, a structure that contains layers of thermal insulation and waterproofing. In turn, the roof decorative coating, protecting the roof from precipitation.

Choice roofing materials for an extension depends on several factors:

Functional role of the room.
Extension architecture.
Construction materials used in the construction of a house.
Roof roofing materials.
Financial opportunities.

If it is impossible to use a single roofing material, then you need to think about how it will look externally, what is appropriate in this case and what is not. It is important to keep the house and the extension in the same style so that the extension does not seem superfluous. Ideally, an additional structure should highlight the house and be its original decoration. If you think through the project well, you can create such an effect that it will seem as if the roof of a private house “flows” onto the terrace or veranda, thus forming one whole.

Roof types:

Flat.
Sloping (the name depends on the number of slopes)
Single and multi-stage.
Domed and conical.
Complex (broken, multi-pincer, etc.)
Ceiling and attic.

A compound roof is used only for extensions that must match the style of the house, for example, classicism or Gothic style. In general, simpler is more popular for extensions. pitched roof, because it will be the optimal, practical and inexpensive option.
A pitched roof can be constructed using different methods, but initially you need to determine:

Construction of an additional building.
Roofing material used.
Roof features.
What layers of thermal insulation and waterproofing will be.
Financial opportunities.

Selecting material for the roof of the extension

Before buying the first roofing material you come across, you need to look through their full list, find out the advantages and disadvantages of each individual material taken. Having compared all the pros and cons, you can choose the best option that will be used for the extension, ideally if it is similar to the material used for the roof of the house.
Previously, the choice of roofing materials was limited, but now in the 21st century the range is practically unlimited, neither in terms of flexibility, nor in color or other factors.

Popular roofing materials:

Fastlock.
Soft roof.
All variations of tiles.
Slate.
Corrugated sheet or metal roofing.
Expensive roofing coverings decorative in nature.

Things to consider when choosing a roof:

Required amount of materials.
Lifetime.
The price of the material, the cost of its installation.
Plasticity, flexibility.
Weight and resistance to external factors.
Fire safety.
Color variability.

Nuances for laying the roof

A simple extension option is a covered terrace or veranda. In this case, the main role is played by the foundation and roof of the extension. The extension itself can be either closed or open, the main thing is that this is a place for relaxation, where there should be no cold and moisture.
It is necessary to determine the angle of inclination - in the optimal case it should be 20-30 degrees, if less, then snow will accumulate on the roof surface, if more, then the roof will be subject to greater wind loads.
When constructing a rafter system, you need to take into account all the subtleties and nuances, use boards and beams of sufficient thickness. The rafters are secured using self-tapping screws or anchor wedges (depending on the material to which they are attached). With proper construction of the rafter system, the roof should have a safety margin that can withstand a hurricane or tornado, regardless of whether they occur in this region or not.
If the extension is not residential and has a “cold” roof, then insulation is not needed here. If you plan to erect a large residential building, you can use gable roof, A attic space should have a triangular shape. Particular attention should be paid to thermal insulation and waterproofing, because cold and moisture are unacceptable here.

Stages of installing a roof for an extension

As an example, you can take the simplest, but at the same time popular option for extensions - a pitched roof with ordinary rafters and a slate roofing pie.

Carrying out calculations, developing drawings. At this stage, the angle of inclination of the roof is determined; it should be from 20 to 35 degrees.
At the edge of the extension we install a beam, the support point of the roof structure. Next, every 0.8-1 meters we mark places for installing rafters. A special beam is secured with anchor wedges into the lower beam and the upper trim. Then the outer rafters are placed on the beam, after which the rest are placed along the cord to the previously marked points.
Installation of waterproofing.
Installation of sheathing.
Laying a layer of insulation between the rafters and the sheathing.
Sew the rafters with plywood or wooden board.
Laying slate according to the technology prescribed in the instructions.

By building or purchasing a private house, owners may be faced with a poorly thought-out layout, which results in a lack of free space inside. An excellent solution to this problem is a turnkey extension to a house made of timber - the price of which depends on the type and configuration, but in any case less than remodeling the house. Such a structure can be used as a summer kitchen, hallway, place for outdoor recreation, storage space, garage.

Despite the apparent simplicity of the design, building an extension will require certain knowledge, construction skills and a certain set of tools. In addition, in order for the object to be safe and stable, it is necessary to build a reliable foundation and frame. For closed extensions, it is necessary to provide wall decoration and an entrance door. Considering that often the extension is adjacent to the house, which means the foundations may be skewed, it is better to entrust the design of such a room to a specialist. This is a guarantee of a well-designed project and high-quality work performed.

What options for extensions can be

There are several most common options for using attached premises.

Porch. Structures can have any number of steps, be rotary and high. For safe use railings are installed. Blocks and wood are used as building materials.

Canopy is the simplest design that can be easily dismantled. It is designed to protect against precipitation and sun rays. It’s nice to have family dinners under the open canopy and relax in the midday heat. The construction of a foundation is not necessary; it is enough to provide support pillars made of metal, concrete, or treated wood. The frame of the structure is fixed on supports. If desired, the walls are covered with polycarbonate.

Room for relaxation in summer. This extension increases living space Houses. The type of foundation chosen is strip or columnar. The walls are erected from warm, durable materials: blocks, timber, slabs. To make the room bright, double-glazed windows are installed. No heating is required for summer living.

Garage as an extension To country house allows for significant savings compared to the construction of a separate facility. It is built on a strip foundation, the walls must be made of non-flammable material. Economical slate, corrugated sheeting, and metal tiles are chosen as roofing. To prevent the smell of gasoline in the house, be sure to install good system garage ventilation.

Capital residential premises with the possibility of accommodation all year round. Construction requires a block or monolithic foundation, brick or block walls. The roof and walls are insulated, and a heating system is provided.

Kitchen-dining room. When installing a kitchen, it is necessary to install communications and install ventilation, so the facility requires careful design. Such extensions are often built on old houses, where there was originally no room for cooking.

To make the building look harmonious, the extension is made in the same style as the main house.

What materials are suitable for building extensions

For the construction of an extension to a country house, plans are drawn up by architects taking into account your wishes. Materials are selected depending on financial capabilities and the purpose of the extension. The most commonly chosen are the following:

Timber of any kind: rounded, planed, glued. Glued material has higher thermal insulation properties, while rounded material has the most attractive appearance. The advantages of timber include affordable cost, high environmental characteristics. It is suitable for construction for any purpose. The wood is treated with special compounds to protect against pests, mold, and mildew. Objects made of timber are built quickly and easily.

Moisture-resistant chipboard or OSB boards used in frame buildings. The material has high sound insulation properties and retains heat well. In residential extensions, additional insulation is performed with mineral wool. The cost of the material is affordable. Experienced builders will quickly cope with the task of covering walls with chipboard or OSB.

Brick. The material has high strength, durability, and a wide range of colors. But at the same time, they will demand the highest price for working with bricks. In combination with double-glazed windows the material is suitable for construction winter garden, greenhouses. Bricks have significant weight, so a reliable foundation is needed for an extension to the house. The most difficult stage in the construction of such a structure is the docking with the main object.

Foam blocks and aerated concrete blocks. The advantages of the material include affordable cost, high thermal insulation due to the porous structure, short construction period from large blocks. The structure is lighter than a brick one and does not require a reinforced foundation. The disadvantages of block objects are the need for cladding, since their surface is destroyed under the influence of precipitation and other negative factors.

Regardless of the material chosen, the safety and reliability of the constructed object correlates with the quality of its connection to the main structure. The simplest option is to build an independent closed foundation. The space between the walls of the extension and the house is filled with insulating materials.

Watch the video for an example of constructing one type of foundation for an extension:

When introducing a new building into the main structure, the frame of the extension is connected by reinforcement to the base of the foundation of the house. To connect the walls, some of the elements of the house frame are dismantled. To make a single roof, the outer rows of the covering are removed and the rafters for the extension are attached to the main beams. When an extension to a wooden house is being built, the price of the work will be higher than for an independent building.

Frame extension to the house

The frame option is a budget option; it does not require large investments. The structures can have modest dimensions of 2x2 m, 2x3 m or be spacious structures with dimensions of 5x2 m, 6x3 m.

For the base of the object, a frame is mounted from metal profile or processed wooden beams. The frame is erected around the perimeter of the building and for each wall separately. Such objects are lightweight and can be built on a columnar or pile foundation.

The created structure is sheathed with internal and outside moisture-resistant chipboard or OSB boards. To increase thermal insulation, a layer of insulation is laid between the plates: mineral wool, expanded polystyrene, sawdust. The thickness of the thermal insulation is usually 50 mm. To prevent the insulation from getting wet, it is waterproofed with a special membrane on the outside and inside.

The roof of an extension to a frame house can be single-pitched, gable or complex in shape. Ondulin, metal tiles, and ceramic plastic are chosen as roofing coverings. The external finishing of the slabs is done with clapboard, block house, and siding.

If you decide to attach a terrace to your house, options, prices and designs need to be studied in advance. In this case, all the pros and cons of materials and construction technologies will be taken into account.

On our website you can find contacts construction companies who offer the service of adding extensions to houses. You can communicate directly with representatives by visiting the “Low-Rise Country” exhibition of houses.

Selecting materials for an extension to a wooden house

Even if a wooden house has a significant area, many owners decide to increase it. In the extension you can equip a children's room, a workshop or a storage room for sports equipment.

The most affordable and in a simple way construction will be a frame structure. It is not inferior in reliability to capital facilities, but is being built in short time. In a wooden building, the frame can be logs or beams; chipboard panels with clapboard or block house are used for cladding.

A more expensive option is to build from timber or logs. But externally, the extension will be in maximum harmony with the main wooden house. Such an object has an optimal microclimate inside.

Extension of a veranda or terrace

Most often, terraces or verandas are added to houses; these structures have some differences. A terrace is an open structure with fencing around the perimeter. It may have a roof combined with the house. The structure is erected on its own foundation or tied to the main object. It is recommended to place terraces on one side of the house or encircle it around the perimeter. On such an extension it is convenient to relax in summer time, it can be used for barbecue.

What elements does an open terrace consist of?

If you order a building open terrace in a construction organization, the kit will include the following elements:

Terrace posts made of wood with a diameter of 10x10 cm. They are installed at a distance of 1.3–2 m.
Elements for constructing a foundation: pillars, piles.
Wooden railings, balusters with carved trim.
Roofing material of the selected color: corrugated sheet, metal tile, ondulin
Batten grooved or planed.

At your request, the package can include any additional elements, for example, balusters are replaced with a continuous clapboard fencing.

Conclusion

If you decide to build an extension to your house, architects and designers will help you draw up a project, calculate the amount of materials needed and the cost of the work. Our specialists will do everything possible to ensure that the extension costs you as little as possible, while meeting all your wishes.

Solving the housing problem if you have your own private house is much easier than in a city apartment. The best option is to make an extension that can be used for a variety of purposes:

full-fledged living space - additional room;
living space with an attic (if the extension is two-story);
utility room - its own pantry, which can largely replace a cellar;
a spacious terrace or veranda where you can relax with the whole family;
garage for cars.

Below we will discuss the basics of technology and step-by-step instruction creating an extension to a wooden house.

Before choosing a specific one construction material and the technology for constructing the extension, it is important to clearly define the purpose of the room. Perhaps you should immediately plan to create an extension in which it will be possible to live year-round - in case of family expansion or arrival large quantity guests.

Types of extensions

There are several types of extensions to a wooden house. They differ in material, as well as installation features:

frame extensions;
from cylindrical timber;
made of brick;
from cinder block.

Before erecting a structure, it is important to take into account all the nuances that may affect the choice of materials and the specific type of extension:

Making the right choice of a specific extension project means correctly correlating the purpose of this structure, the features of the house to which it is attached, with the technology and material of manufacture. To do this, it is important to understand how each type of such structure is built.

Do-it-yourself frame extension: step-by-step instructions and video

A frame extension has a number of advantages:

the design is quite simple, and if everything is calculated correctly, it is quite possible to do it yourself;
it is erected much faster than brick and cinder block structures;
the design is quite light in weight and does not require much effort during operation;
In terms of thermal insulation, durability and other consumer qualities, a frame extension to a house is not inferior to others types of structures.

NOTE. If you intend to build a two-story extension, it is worth considering this option - the structure is lightweight and will not create excessive pressure on the ground, so the risk of subsidence is noticeably reduced.

Preparation for construction

On preparatory stage it is important to solve the following problems:

What will the frame material be? wooden beams or metal profiles.
What type of extension will be connected to the main building?
Accurately calculate all dimensions of the structure and develop a detailed drawing.
Collect all necessary materials and tools.

First of all, it is important to decide what type of structure will be built - as a continuation of the house with an increase in the main roof to install a single roof, or as an adjacent building.

It is clear that the second case will be cheaper, simpler and faster - the extension will simply be adjacent to the wall. You can make access from the house directly into it if you make an appropriate hole and install a door.

A diagram of the connection between the structure and the house is presented below.

Structurally, this solution consists of a roof placed on supports. The roof is standardly made of rafters and support boards. For a longer service life, it is advisable to insulate it and lay out a layer of waterproofing. As a rule, it is based on the usual strip foundation.

Interface with the main part of the house occurs at 2 points:

wall;
roof.

The connection in each of them has its own characteristics, which will be described below. Preliminary sketch of the extension, as well as practical advice things to consider before starting work:

At the same time, for the roof of the extension it is better to choose a material that is elastic enough to make the necessary corrections. You can purchase corrugated sheeting (height within 1 cm) or soft tiles.

In this sense, slate or traditional ceramic tiles and metal tiles are not suitable.

The frame is made of wood or metal. In this case, all parts should consist of only one type of material - then the extension is more reliable and lasts longer.

NOTE. Even if the house is in good condition, but quite old, the rate of its subsidence will be several times higher than the subsidence of the extension. Accordingly, it is better not to use a rigid type of connection of the structure to the main wall. In this case, another type of installation is used - “groove-ridge”.

As for tools, you don’t need any special equipment: it is important to have a screwdriver, a saw, pliers, a building level and other tools for working with wood.

Installation work must be carried out by at least two people - some stages will require joint efforts.

Laying the foundation

The first stage of work is laying the foundation. Since in the vast majority of cases, the construction of a house does not involve the construction of a foundation for an extension, the foundation must not only be laid correctly, but also reliably connected to the main foundation.

NOTE. If you are designing the construction of a newly built house, it is better to take into account the extension right away. It can be made after some time, and laying the foundation along with the foundation of the main building is a technically correct option. In this case, the house and the extension will be a single whole, which will ensure their reliability.

The main requirements for the base of the extension are the following:

reliability – stable maintenance of the weight of the structure without subsidence: especially important for extensions made of heavy materials or two-story structures;
maximum identity with the main foundation in terms of material and laying depth;
the most complete adhesion to the main foundation.

Most often, strip foundations are chosen for extensions, since they are quite capable of coping with such loads. Moreover, installation features always depend on the type of soil. You can lay monolithic foundations, made of brick or concrete blocks, and fill them with drainage materials.

Schematic diagrams of the bases are presented in the figure.

The technology for constructing a strip foundation for an extension does not differ from the usual one. In short, a trench is dug, reinforced and filled with concrete.

Connection of the foundation with the main one

This is the most critical stage. which needs special attention. Traditionally, two types of connections are used:

"tape-tape";
"slab-slab".

According to the “tape-to-tape” type, the stages of work will be as follows:

On the installation side of the extension, a trench is dug corresponding to the depth of the main foundation.
Next, a hole half a meter in diameter is drilled at the base of the house - for the corners of the foundation of the extension. For all other parts, the hole corresponds to the diameter of the reinforcement at a depth of 2/3.
The reinforcement is driven into the foundation of the house; a wooden wedge is used for this.
The foundation of the extension is formed using the driven reinforcement.

Installation according to the “slab-slab” scheme is possible in 2 cases:

the width of the main foundation allows for appropriate work (from 450 mm);
the plate protrudes from the base (at least 300 mm).

Thanks to an extension, it is often possible to solve another important problem - strengthening the old foundation and thereby supporting a sagging house. Visual videos instructions:

Features of laying the foundation in the case of an old house:

Installation of flooring in an extension

Correctly making the floor in the future room is important from the point of view of 2 factors:

thermal insulation;
surface evenness.

It is important to make a high-quality floor, especially in cases where the extension to the house will be used as an additional room with the possibility of year-round use.

The strip foundation allows you to install both a concrete floor and make it out of wood. In the case of a columnar base, it is only possible to produce a wooden covering.

Concrete floor

The sequence of technology for laying this floor looks like this:

The concrete surface is quite cold, so this floor needs careful insulation, especially in the northern regions.

Wooden floor

On a columnar or strip foundation, a floor created on the basis of wooden floors. It needs additional processing to avoid rotting, however wood flooring much warmer than concrete.

The installation sequence for a wooden floor looks like this:

If an extension to a house is being built as a permanent structure, then preparatory work for laying sand, crushed stone or expanded clay, as in the case of a concrete floor.
A roofing felt substrate is placed on the foundation.
Load-bearing beams are laid on it. If the foundation is columnar, then they are mounted directly on the pillars, the length is adjusted in accordance with the interval. If the foundation is strip, it is important to install intermediate pillars at a certain interval or use long beams if the extension is small in area.
A wooden covering is mounted on the beams.

All wooden parts must be carefully treated with varnish to prevent rotting.

A clear example of installing a wooden floor in a cinder block extension is shown in the video.

Frame installation

The next stage is associated with the direct construction of the frame structure. To do this, you first need to install the strapping beam. If it is assumed that the wall thickness will be 200 mm, then the dimensions of the end bar will be 25-40 mm, as shown in the detailed diagram.

The end result is a design that looks something like this.

Cutting out the groove in the base can be done completely or incompletely. Can be jointed without cutting using a steel angle.

The lower harness is performed in several stages:

The nest is mounted in the insert.
The overlay is nailed into the base.
The support post is secured with a bracket.

The top trim is formed for reliable installation of the floor beams, as shown in the diagram.

NOTE. The interval between vertical supports should be at least 50-60 cm, since in this case it will be possible to easily lay insulation ( mineral wool, polystyrene foam, ecowool, etc.). In addition, there is no practical need for a more frequent arrangement of racks.

The general design of the frame is shown in the diagram.

The construction of walls occurs according to the following algorithm:

Installation of a pre-fabricated lower trim on the foundation. The harness is screwed using dowels.

A waterproofing layer - foamed polyethylene, roofing felt or other material - must be placed between the piping and the foundations.

Vertical beams are nailed to the wall of the house if rigid fastening of two structures is expected. If you just need to build a nearby building, then first make corner posts with temporary fastening.
Vertical bars are installed. Their height is selected depending on the number of storeys of the structure, as well as on the method of connection to the main roof of the house.
Next, the top trim is mounted.
The last stage in installation is making holes for windows and doors.

ADVICE. If you plan to build a large extension with a large number of beams, then it is more convenient to assemble the frame separately, installing all the beams on the lower frame. In this case, there is no need to fasten each element using temporary slopes.

Assembling the roof and connecting it to the main roof

Installation of rafters is carried out in the same way as for a regular roof, however, the need to connect the roof with the roof of the house gives rise to a number of features of this work.

In general finished design can be schematically depicted as follows.

After erecting the frame, the roof material of the house on the side of the extension must be disassembled so that the rafters appear. It is to them that the connecting rafters of the extension are mounted. Installation is carried out according to principle of strict triangle, while it is important to place an additional beam in front of the acute angle (shown by arrows in the figure). These elements also serve as an additional measure of protection during snowfalls, which is why they are also called snow supports.

The sequence of actions for installing the roof can be briefly described as follows:

The rafters from the extension are mounted with the top frame frame.
The upper end of the rafters is connected to a purlin, which is pre-installed on the roof or attached directly to the roof rafters.

Video installation features

NOTE. You should not connect the rafters of the extension to the house in a rigid manner. This can damage the structure due to uneven rates of shrinkage of the main room and the extension. The optimal solution to this problem is the use of a sliding structure that provides free movement bottom support.

Finishing and insulation of the roof

At this stage, the roof is completely finished with its sealing and insulation, as shown in the diagram.

NOTE. If the roof of the extension simply adjoins the wall of the house, and does not organically connect with its roof, then a sealant is used for insulation, tightly closing the hole between the roof and the wall, as shown in the diagram.

Construction and insulation of walls

One of the last stages is the construction of walls and their insulation. An extension is a durable structure, and even if it is used only for economic purposes, it is important to create enough good insulation so that temperature changes cannot damage the internal surfaces of the walls and ceiling.

The structure of the wall can be schematically represented as follows.

In fact, this is the final stage of the construction itself. Next, the following work should be done:

finishing work inside the extension:
exterior cladding of the building;
creating a transition to the house;
production of windows and doors in the building;
carrying out all necessary communications.

It is important to treat all wooden structures with special solutions that prevent rotting and harmful effects temperature changes.

Timber extension

The fundamental stages of constructing an extension (pouring the foundation, constructing walls and installing the roof with subsequent insulation and finishing works) do not depend on the choice of specific construction material. However, depending on it, their own technologies are selected, which differ markedly from each other.

Construction of the foundation

In the case of an extension made of timber (profiled or round), the differences begin already at the stage of laying the foundation. Since the weight of the future extension will be significantly greater than the weight of the frame analogue, accordingly, the base needs to be more reliable.

Often a tiled foundation or a pile foundation is used, less often a strip foundation (for small extensions it is quite suitable). In any case, it is necessary that it sits for at least 1 year.

From the point of view of simplicity and cost reduction of work, the best option would be to create pile foundation, which can be built independently of the main foundation of the house.

Walling

Building walls is quite simple from a technological point of view. The only drawback of the beam is that it is quite heavy, and at least two people need to work with it.

The fastening materials used are:

metal staples and plates;

brackets;
steel corners;
self-tapping screws, screws, nails.

Other works

The technology of wall construction, insulation and finishing is not fundamentally different from that described earlier.

In the case of building a structure from timber, two-story structures can be easily made. Of course, in this case, special requirements are placed on the foundation and floors.

Brick extension

Brick extensions to a wooden house are built less frequently. They are great for living, they can also be used as a utility room.

Most often in such cases a monolithic foundation is used. In this case, the brick structure can serve as the basis for the construction of a second similar floor or attic. Installation of floor and roof technology is not fundamentally different from those discussed above.

Cinder block extension

And another cheaper and faster option for building an extension to a wooden or other house is from cinder blocks (foam blocks and gas blocks are also used). Such a room can serve as an additional room, but is most often used for household purposes.

The construction of a cinder block structure occurs very quickly due to large sizes building material. This option is great if the owners want to make a garage for a car or an ordinary canopy or veranda.

And finally - short video overview of the main stages of constructing a frame extension to a wooden house.

Quite often, it is necessary to build an extension to an already built house, which will serve for household needs or as a platform for summer holiday. Further in the article we will talk about what tools and materials may be needed, as well as in what order construction work should be carried out.

Calculation of the slope of a pitched roof

In terms of design, the simplest roof is considered to be a pitched roof. However, even this type of extension roof requires some preparatory work. The first thing you will need to do is complete the roof design. At this stage, a drawing is drawn up indicating the planned slope of the slope.

It is worth noting that the slope of the roof directly affects the efficiency of its functioning, as well as the durability of the roofing covering. Of course, competent calculations will significantly simplify and speed up construction. The amount of roofing material used for an extension with a pitched roof will increase as the angle of the slope increases.

The calculation of the slope will depend, first of all, on climatic conditions in a certain region. This angle will be steeper the more precipitation expected in winter in a particular region. A correctly selected value will allow timely and complete removal of rain and snow from the roof surface. At the same time, if a particular area is characterized by strong gusty winds, the slopes should not be made too steep.

Roofing material that will cover the extension to the house with broken roof th, also affects the magnitude of the slope:

for slate or tiled roofs should be from 22º;
roofing material laid in 2 layers requires a minimum slope of 5º, and in 3 layers - from 15º;
The slope of the corrugated roof must be at least 12º;
metal tile roofs can have slopes with an angle of 14º;
ondulin, like roofing felt, is laid on slopes with minimum slope at 6º;
soft tiles are mounted on roofs with slopes inclined at least 11º.

Common practice shows that the maximum roof slope of an extension to hipped roof is 45º. It is worth noting that the choice of roof slope angle will be largely influenced by the expected loads on the rafter system caused by wind and precipitation. A design error can result in additional costs if the extension falls due to excessive loads.

Necessary materials for the roof of a house extension

The rafter system of the extension with a pitched roof is made of wooden beams, on top of which the roofing covering is laid (read: “How to make a pitched roof for an extension to a house with your own hands - instructions for building a barn roof”). The frame is made of hardwood, which has been thoroughly dried, treated with antiseptics and primer. Additionally, it is worth opening all wooden elements with fire retardant substances. Such treatment can significantly extend the service life of the rafter system.

So, to create a roof over the extension you will need:

beams for rafters, supports and others structural elements;
edged board for cladding ends and sheathing;
waterproofing and insulating material;
roofing covering.

As for roofing coverings, as a rule, a gable roof with an extension is covered with the same type of material. At the same time, each owner proceeds, first of all, from his own material capabilities. If you are looking for an inexpensive way to cover the roof of a shed, you should pay attention to budget roofing materials.

The thickness of the beams will depend on the expected loads of rain and snow, as well as the total mass of the roofing material. In this case, beams with dimensions between 120×120 mm and 150×150 mm can be used.

electric saw or hacksaw;
drill;
axe;
screwdriver;
hammer and furniture stapler;
nails and screws;
roulette and level.

The consumption of screws or nails is 8-10 pieces per 1 m2. As for the material for insulation and waterproofing, then total area surfaces add a margin of 10-15% for joining, trimming and overlap. The rafters are calculated based on maximum distance 1 m between them.

Installation sequence

If the preliminary design did not provide for the arrangement of a house with an extension under one roof, it is worth making sure that there is a gap of at least 5 cm between the roof of the main building and the additional room. In addition, it is important to correctly link the extension to the wall of the main house, so that rain or snow does not seep into the gap.

In order to attach the roof of the extension to the house as reliably as possible, construction must begin with laying the Mauerlat. It should be thicker, the steeper the slope and the heavier the roof covering.

This beam should be fixed to the walls as firmly as possible, since rafter legs will later be attached to it where the walls of the main house and the extension will connect. In this case, the installation of the rafters is carried out in pre-made grooves in the Mauerlat. Between adjacent rafters there can be a distance of 60-80 cm, but not more than 100 cm.

Please note that the slope of all rafter legs must be the same. Otherwise, due to distortions, water will flow under the roofing material and destroy wooden structures.

Upon completion of the construction of the rafter system, insulation work begins. In cases where the length of the rafters is too long, additional supporting elements are placed between them. On top of them, perpendicular to the rafters, a polyethylene film, roofing felt or other material for waterproofing is spread. To ensure tightness, the insulation is laid with an overlap and the joints are taped with construction tape. The roofing material is fixed to the rafters using a stapler.

How to join the roof to the wall

The junction of the walls of the house and the roof above the extension is additionally sealed to prevent water from flowing into the cracks. When planning the connection of the roof to the wall of the building, you should decide how to connect the roofs of the house and the extension. First, the top layer of roofing material is rolled out over the surface of the roof of the extension and heated with a blowtorch. After this, the material is glued to the main wall.

At the next stage, the sheathing is attached over the waterproofing layer. It is fixed perpendicular rafter legs from a 5x5 cm batten. The sheathing pitch is selected based on the type of roofing. If it is a solid material, then each sheet should be supported by at least two bars. For soft roofs coatings, a continuous sheathing is filled with particle boards or edged board.

The final stage of building a roof over an extension is to install the roofing covering. The method of laying it depends on the type of material. Be sure to make sure that the coating is laid in a continuous layer without gaps. Finally, the side parts of the roof are covered with edged boards.

Is it necessary to insulate the roof of the extension?

Work on insulating the roof above the extension can reduce heat loss, as well as increase the efficiency of heating, if it is provided in such a room. In order to carry out insulation work, it is necessary to make a rough ceiling before installing the waterproofing layer. The selected insulating material is laid on it, covered with a layer of waterproofing, and then all other installation work is carried out.

The inside of such a ceiling can be sheathed with plasterboard or moisture resistant plywood. Don't forget to also insulate the ends of the roof to reduce heat loss due to side winds. In this case, any available material can be used

The external decor of the end parts of the roof above the extension can be done in any way finishing materials at will.

Roof of house extension

After the bulk of the work on building a house has been completed, quite often there is a need to build an auxiliary room adjacent to the house, for example, a veranda.

There are quite a few options for building such a room, but they all have one thing in common - how to make a roof on an extension to a house so that it fits as closely as possible to the wall of the house, while still having a sufficient angle of inclination. This is ensured the right choice materials, as well as a suitable installation method.

Choosing a roof type

In order for the extension to harmonize as much as possible with the main structure, the decoration and appearance of the buildings should be as close as possible. An exception can be made for glass greenhouses or summer dining attics - the material for this type of extension can be transparent. The main parameters influencing the choice of roof type include:

The type of building materials of the main building, as well as its general architecture;
The main function of the extension;
Construction budget;
Roof pitch angle.

If it is impossible to achieve a complete match of building materials, then you should choose a solution in which the materials will complement each other as much as possible.

Typically, the type of roofing for an extension is chosen as simple as possible, for example, a single-pitch adjacent roof with a slope from the wall of the house. The exception is houses built in classic styles architecture, for example, Gothic.

Types of pitched roofs

There are several types of pitched roofs for an extension adjacent to the house:

Non-ventilated (used if the accumulation of condensate is absolutely excluded);
Ventilated (ventilated by external air flows);
Partially ventilated.

A prerequisite for adjacent roofs is that the angle of inclination must be at least 20 degrees. This slope will prevent the accumulation of snow mass on the surface. It should also be remembered that the roof of the extension should extend under the roof of the building and be as close to the wall of the house as possible.

Choosing roofing material

As already mentioned, the roof covering of the extension should coincide as much as possible with the main covering of the house. Modern market building materials allows you to select both the material and the most convenient and suitable technology its styling.

Before making a roof for a house extension, you need to choose a roofing covering based on the following parameters:

Area and total weight of the structure;
Reliability, durability, resistance to fire, aggressive environments and temperature changes;
Costs of covering and roofing installation work;
Roof shape and angle;
Possibility of performing repair and restoration work in case of damage.

Features of the work

If you plan to make the roof yourself, then first of all you should carefully understand the characteristics of the selected material, as well as the methods of its installation. This will allow you to objectively assess the possibility of performing the work yourself.

In addition to the roofing, you should select materials for the sheathing and rafter system. This also takes into account all design features, as well as technological characteristics.

For example, if a soft roof is chosen as the material for the roof, then a board made of boards of the same thickness, which is fixed to the rafters, should be used as a sheathing. Also, do not forget about the drainage system, the costs of which should also be included in the general budget.

Installation technology

For example, we can consider the installation of the simplest slate roof on ordinary rafters. Installation should begin by drawing up a detailed drawing with calculations, which must indicate the expected angle of inclination of the roof.

Do-it-yourself veranda extension to a wooden house

Calculations will help you avoid mistakes during the work process and will help you control every step of the technical process.

After all calculations have been completed, installation begins directly. First, a beam is attached to the edge of the extension, which will serve as a support for the main structure. Next, mark the points where the rafters will be attached. After this, a beam prepared for the rafter system is secured to the lower beam and upper frame using anchor wedges.

You should start fastening the rafters from the edges, after which, using a stretched fishing line, the entire structure is aligned along the marks. Next, they proceed to the installation of the waterproofing layer. Most often, glassine, roofing material or thick cellophane film are used for this.

However, other materials are often used, for example, stekloizol or rubemast. The waterproofing is fixed to the pre-applied sheathing.

The sheathing pitch depends on the type of roofing material. If the roof needs to be insulated, then insulation (for example, foam plastic) is laid between the rafters, and the rafters themselves are sewn up from the inside with sheets of plywood, OSB or plasterboard.

Fastening material

After completing the installation of waterproofing, you can proceed to attaching the roofing itself. Before installing a roof on an extension to the house, you should familiarize yourself with the installation rules and strictly follow technological process specified in the instructions for the material.

Watch the video:

If slate or a material similar in structure (for example, ondulin) is chosen for the roof of the extension, then fastening should begin from the edge of the roof to the wall of the building with an overlap of sheets of at least 100 mm.

Attaching the sheets to the sheathing should be done using slate nails or roofing screws at the top point of the wave, at least 4-5 points per 1 m2.

Construction of wooden extensions

Frame extension to the house: we build it ourselves

According to their purpose, all extensions to the house are divided into:

Depending on the type of material used, extensions are:

At the first stage of preparation for construction, it is necessary to decide whether it is planned to construct a capital building or not. Construction of a canopy or terrace is quite possible without a project carried out by a specialized organization; a plan or diagram may be sufficient. The construction of a living room or garage is best done using a specially designed or ready-made project for an extension to a wooden house that is tied to specific conditions. Savings at this stage, as a rule, result in additional, much larger costs during construction.

Capital buildings

Frame room extension project

Advantages of using a frame structure:

speed of construction;
no settlement of the structure during the first stages of operation;
small load on the foundation, and as a result, minor requirements for it;
excellent compatibility with the wooden structures of the main private house.

A frame structure is especially suitable for the construction of a two-story extension to a country house, since it is much lighter than other types of construction.

Foam block extension project

An extension made of foam blocks is one of the most common options, as it simultaneously combines the relative cheapness of the work and its simplicity. In addition, these are not all the advantages of using this technology.

speed of construction;
durability of the structure (at least 50 years);
light load on the foundation (a foundation on pillars is sufficient instead of a strip one);
structural strength;
simplicity of construction technology;
the ability of the material to “breathe”.

necessity exterior finishing facade due to the unattractive appearance of the blocks.

Timber extension project

Structurally and technologically, everything that was said about frame extensions can also be applied to structures made of timber. In fact, a combination option is most often used.

Key points when building an extension from timber:

the foundation for it must be similar to the foundation for the main building and connected to it;
it is possible to use a more economical pile foundation, of course, in the case of structural calculations;

it is necessary to create an expansion joint between the house and the extension, which will prevent damage to the walls during shrinkage of the new structure;

The technology for constructing the structure of the walls and roof of the extension is similar to the technology for building a house.

Non-permanent buildings

Veranda made of polycarbonate

The established opinion that a veranda is a warehouse for storing unnecessary things (tools, bicycles, skis and other junk) is fundamentally wrong. In fact, this is an excellent opportunity to create a comfortable and beautiful recreation area. Especially if you use modern designs and materials for this.

Key points when building a veranda:

can have almost any configuration - rectangle, square, semicircle with an arch-shaped roof;

the lightness of the structure allows its construction on a minimal foundation, for example, a strip foundation with a depth and width of only 30 cm on a sand cushion 20 cm thick;

it is advisable to construct a small plinth to which the frame structures are attached;
Due to the properties of the material, polycarbonate itself is easy to cut and mounted on an already assembled frame.

Canopy

A canopy is constructed, as a rule, in order to protect any used space from precipitation. In this way, you can arrange almost the entire area adjacent to the house for a summer dining room, playgrounds and much more.

The canopy structure usually consists of:

pillars dug to a depth of about 0.5 meters and filled with concrete;
horizontal beams, one of which must be attached to the wall of the house;

rafters and lathing on them;
roofing material.

The existing variety of materials and various structural elements allows you to create a variety of combinations when constructing sheds. But most often, when building an extension to a wooden house, wood and metal tiles are used.

Extension to a house roof to roof - installation instructions

Some may think that an extension is a utility room, and there is no need to show much creativity when arranging the roof. But there are also extensions that outshine the house itself with its beauty and functionality. And it is for these reasons that the upper part of the building above them can be different: either single-pitched or multi-pitched.

In principle, an extension is erected not only to expand the living space, but also to equip a summer veranda or kitchen, and therefore a simple lean-to structure is often built over them.

But if you need to add a large room to the house, even larger than the area of the main building, then arranging a broken type of roof will be quite reasonable.

A gable roof is suitable for verandas or summer terraces when you need to expand the main area or create an additional place for relaxation. So the choice of design depends on the functionality of the attached room.

Roof requirements for an extension:

It cannot be a single structure with a residential building;
A small indentation from the newly built walls is provided;
The roofing material is laid overlapping, which ensures water resistance;
Since the extension will be located below the level of the main building, all precipitation will roll onto it, so the requirements for waterproofing are very stringent.

Roof installation

The durability and comfort in the room will depend on how durable and high-quality the roof is built over the extension.

Let's consider a lean-to option, with the arrangement of a simple rafter system:

Specify the slope of the structure: if it is large, it will be difficult to install the roofing material, and if it is small, precipitation can break the coating;
We lay the main mounting beam on which the rafter system will rest: along the edge of the load-bearing wall of the extension. At a distance of approximately 1 meter, markings are made for attaching the rafters, then using anchor wedges they are fastened along the lower base and upper trim. It is best to start with the outer rafters: having strengthened them, it will be easier to install subsequent ones;
We arrange the sheathing for waterproofing, the selected material is placed on it;
If a warm extension is being built, then the roof should also be insulated with plywood or wooden sheets, mineral wool.
A layer of insulation is placed under the rafters and sheathing;

Now you can lay the roofing material.

Installation of a gable version:
Again, you need to start with arranging the rafters. If you plan to allocate space for an attic, then you must immediately determine its dimensions and install separate racks for fastening the walls; By load-bearing walls
the frame of the rafter system is installed, it is attached to the base of the building;
The rafters themselves are fastened in pairs, sewn together with studs or anchor connecting parts;
After this, they proceed to arranging the sheathing for the roofing material and installing the roof ridge;

Upon completion of this work, a waterproofing layer should be laid, over which the main roofing material can be laid.

Extension to a house with a sloping roof

The arrangement of this type is a little more expensive than the previous options, but the structure itself will be much more functional: under such a roof you can build an attic, additional room, which is especially important for a large family.

The peculiarity of this design is a two-stage rafter system: first, the lower tier is mounted, a frame for the second tier is installed on it, and then everything is assembled under one ridge.

The steps are almost the same as for other types of installation: after installation of the rafters, the sheathing, waterproofing and roofing material are prepared.

Roof of an extension to a wooden house Let's look at the arrangement of a pitched roof for an extension to wooden structure

step by step:
First you need to determine the angle of inclination and what material will be covered: for example, slate is heavy in itself, and it requires a strong rafter system. Various for arrangement level structures
houses and extensions, the roof of the latter should be lower than the main roof.
Fastening is carried out with construction pins or anchor locking of all parts.
The sheathing is being constructed. If a warm room is provided, then insulation is laid under it, otherwise not. If it is planned to lay soft roofing material, then instead of the sheathing they install dense plywood panels. And the distance between the sheathing boards is under sheet material determined by the size of the sheets themselves.
Waterproofing materials are attached directly to the rafters with an overlap. Ordinary roofing felt rolls are well suited for these purposes, but materials treated with antiseptics can also be used.
Arrange the roof overhangs: they should extend about 10 cm from the walls of the building, cover them with the necessary material that is in harmony with general view both houses and outbuildings.
Upon completion of installation, anti-wind boards or metal strips are nailed to the ends: the roof will not vibrate from gusts of wind.

Features of arranging shed roofs on an extension

When carrying out work, you should first consider the following points:

Precipitation from the roof of the extension should not fall under the residential building: it is built close to the main building;
If observed in winter time heavy snowfall, then I make the slope with a large angle;
Outline the placement of the drainage system on both roofs;
It is important to determine the required docking point for buildings: thus reducing the overall loads on the joint site.

Insulation procedure

To ensure a comfortable environment, you should approach insulation thoroughly. Be sure to choose high-quality materials and take into account design features.

The insulation procedure consists of several steps:

Installation of a hydrobarrier layer:
Laying the insulating layer;
Arrangement of vapor barrier;
Arrangement of gaps for self-ventilation;
Interior finishing works.
There are several ways of insulation:
Between the rafter system;
Directly under laying roofing material;
Internal insulation of the attic roof.

The first method usually uses mineral wool as insulation. First, a layer is laid throughout the rafter system waterproofing material, for example, a membrane. Please note: on the one hand, it is treated with a composition that does not allow moisture to pass through, and on the other, with a vapor barrier layer. Therefore, a layer of mineral wool is covered with the side where there is impregnation against moisture.

Start styling from the bottom layer. Layers of cotton wool are overlapped and secured with construction tape. But the membrane should be installed at intervals of 0.5-1 cm: it, like other materials, has the same physical properties: at low temperature she shrinks. It can be secured with a stapler or rust-treated nails. Now they create ventilation gaps: this way excess moisture will evaporate. The waterproofing is secured with a grid of thin slats, and it itself is also nailed with stainless steel nails.

The insulation does not need to be installed immediately, First, it is allowed to take a slightly horizontal shape. After some time, the mineral wool is cut into small sheets, which will be laid between the rafters. At the end of the layout, cover the cotton wool plastic film, the material is attached with an overlap.

If you lay it on top of the rafter system, you should use sheets of expanded polystyrene, under which you need to arrange a base, which is done like this:

Lightweight building materials are nailed to the rafters: plywood sheets, thin boards, and they will serve as the basis for laying the heat-insulating layer.
A vapor-proof membrane is attached to a wooden base, but you can do without it.
Now you can lay and attach the insulation sheets. Proceed to laying the roofing material.
All work is accessible to the common man, there is no difficulty in it, you just need to follow the order of work, and the roof of the extension will last a long time.

How to make a roof on an extension to a house

Extension to a house – residential or non-residential premises, located next to the house and having at least one common wall with it. The extension is installed after the construction of the main building; as a rule, it should be developed separate project and take into account the individual characteristics of the architectural element. All of them affect the tightness and durability of the roof.

How to make a roof on an extension to a house

The main mistakes during the construction of an extension roof

Inexperienced developers do not pay due attention to compliance building codes and rules, they believe that an extension is the simplest object and does not represent anything complicated. As a result, not only leaks appear on the roof, but also the stability of the entire structure is compromised. What should you pay attention to?

Foundation

If the foundation of the house is treated with due attention, then the extension can be built almost on the stones. The reasoning is that the extension is light, the load on the foundation is small, a real foundation is not needed. This is a big misconception; a weak foundation causes vibrations in the extension and facade walls of the house. Due to such vibrations, cracks inevitably appear between the roof of the extension and the main building, allowing water and snow to enter through them. It is almost impossible to completely get rid of cracks; you will have to do it every year. current repairs to eliminate leaks.

Important. The depth of the foundation of the extension should be the same as the depth of the foundation of the house. To increase the rigidity of structures, it is recommended to additionally connect them together using rods of construction reinforcement.

Foundation for an extension to a house

Walls

For bricks, niches half a brick deep are made in the facade wall.
If the extension is made of concrete blocks, then every three rows they are fixed with pieces of reinforcement.
Wooden walls are tightened with staples or metal corners.

An example of joining the walls of a log building with the walls of a wooden house

These measures can only slightly increase the stability of the extension. But, as mentioned above, only a solid foundation fully guarantees the immobility of the structure and the tightness of the roof.

Roof

Two types of roofs are used for extensions.

Roof type on the extension Brief description of technical and operational characteristics

Enough complex roof for an extension - it is necessary to make an adjunction to an existing roof. To do this, it is first dismantled, the rafter system is redone, and problems with valleys and other elements are solved. Such a roof on extensions is recommended only in cases where they will be warm and habitable. A gable roof does not reduce the height of the room, allows you to insulate the ceiling and minimize heat losses extensions. Gable roof Only professional builders can build.

The simplest design, can be done by novice builders. Advantages: ease of construction, low cost and reliability. Disadvantages - difficulties with ceiling insulation, in some cases it is necessary to slightly reduce the height of the premises to ensure minimum inclination stingray

For example, we will take a simple type of roof for an extension - flat, adjacent to the façade wall made of foam blocks.

Step-by-step construction instructions

Prices for roofing materials

Before starting work on the roof, you need to prepare the materials. To work you will need:

Lumber.

edged boards

Edged board 50x150x6000

Important. Unedged boards must be sanded, otherwise bark beetles will damage the wood within a few years. For guard wooden structures impregnation is required. It is recommended to use a comprehensive one that simultaneously protects against pests and fire.

Wood fire protection agent

Nails and screws

To make a roof, you need ordinary measuring and carpentry tools. Using electrical equipment is much simpler and easier, but if they are not available, then such a small roof can be built manually.

Step 1. Saturate the lumber. You can buy any antiseptic; they all do their job quite well. A prerequisite is that the boards must be dry. The antiseptic is diluted with water, the proportions are indicated by the manufacturer. Impregnation is done at least twice on all sides. Before starting work, lay the boards on a clean and flat surface, can be impregnated with a brush, roller or pneumatic spray gun.

Impregnation of lumber in this case is carried out with a roller

Step 2. Install the Mauerlat. It must lie on a flat surface; for this, the upper plane of the last row of the building must be leveled. For work, a cement-sand mixture or tile adhesive is used if it remains after any facing work. Open bags with tile adhesive cannot be stored for more than 2-3 weeks, it is very hygroscopic and will absorb moisture and harden. In order not to throw away the glue, use it for other construction work at the first opportunity. You can level the surface with a wooden trowel or a metal spatula. Make sure that the plane is not only level, but also strictly horizontal.

Applying tile adhesive

For the Mauerlat it is necessary to use 50×150 mm boards or timber; as a waterproofing layer it is better to use ordinary roofing felt. But there are substitutes here too. If thin foam polyethylene remains during flooring, it does not need to be thrown away. This material does not allow moisture to pass through and perfectly replaces roofing felt. Cut the waterproofing into strips 2–3 cm wider than the board and staple it to the surface of the Mauerlat.

The material is fixed with a stapler

Step 3. Fix the Mauerlat to the reinforcing belt. There are several mounting options:

when laying the last row of the extension, install metal studs between the seams;
the studs are concreted when pouring the reinforcing belt;
fix the board to the wall with special dowels.

In our case, the third option is best for several reasons. Firstly, the extension is small in size, the loads on the rafter system are insignificant, there is no need to provide for very reliable fixation of the elements. Secondly, a board is used as a mauerlat; it can be easily drilled on site without preliminary marking. Thirdly, work is greatly simplified and accelerated. There is no need to take measurements of each stud, shift the heavy beam several times thin wall, drill deep through holes strictly at right angles.

Dowel diameter 12 mm, length ≈ 150 mm. How is it fixed?

Place the board exactly in place, check its position, and correct errors if necessary.
Prepare your instrument. To drill holes in the wall, you will need a drill with pobedit surfacing Ø 12.5–13 mm and a length of at least 200 mm. Why do you need such a long drill? The length of the dowel is 150 mm, while the depth of the hole in the wall is only 100 mm. If the drill has the same dimensions, it will be impossible to remove concrete dust from the hole. As a result, the dowel will not enter the hole to its full length; fixing the Mauerlat will not ensure its stable position during various loads from the rafter system.
Stand on the board, first drill holes in it using an ordinary drill.

At this point, the preparatory work is completed, and the installation of the roof beams for the extension can begin.

Installation of floor beams

Prices for timber

To increase the strength of the structure near the wall, they should be fixed to a board nailed to the masonry.

Step 1. Put it on the opposite wall extension board of the same thickness as the mauerlat. Check their position, they must be located strictly in a horizontal plane, otherwise the ceiling will be sloped. Temporarily place another one on the horizontal board on its edge; the beams will be fixed in this place. If there is an exit of the floor beams from the main building, great; you can use them to navigate the position of the ceiling and other roof structures of the extension and attach the board to them.

Layed board, checking horizontality

Important. Be sure to provide a waterproof seal between the board and the wall. It should perform two functions: protect the board from moisture from the wall and prevent leaks into the cracks. It is recommended to choose foamed polyethylene as waterproofing. Its pores are closed, which ensures tightness. And high ductility indicators completely compensate for all possible fluctuations in the size of the cracks.

Step 2. Attach the waterproofing and sealing to the board and mark holes for screws approximately 10cm long and 7mm in diameter.

If the ends of the ceiling beams of the house do not protrude from the wall, then they need to be fixed with special dowels. The board must be firmly attached and subject to significant multidirectional loads.

Practical advice. When screwing large-diameter hardware into any board, it is necessary to make holes for them. If there are no holes, then greater tensile forces appear and the board may crack. And such an element will have to be changed; the rafter system is made only from intact and healthy boards.

The diameter of the hole being drilled should be 1-1.5 mm less than the diameter of the hardware; it should not wobble. First, the board is fixed to the outer holes and its position is checked. If everything is normal, then you can tighten the remaining screws.

Step 3. Fasten the beams in place. There are several mounting options, but the simplest and most reliable is to use special perforated metal elements (stands, stops, holders). They are sold in construction stores, at a cost available to all developers without exception. This is an excellent solution for inexperienced builders; the beams are fixed firmly, easily and quickly. In this case, there is no need to maintain greater accuracy of the elements; a spread in length within the range of 1–1.5 cm is not considered critical. Make markings and secure the holders; it is better to fasten them with self-tapping screws. The lower plane of the holders should be located in line with the plane of the board; due to this position, the ceiling beams will be horizontal. The pitch of the beams is ≈ 60 cm.

Fixed metal holder

Practical advice. First fix the fasteners with only two self-tapping screws, screw in the rest only after final leveling ceiling beams.

Step 4. Place the prepared and impregnated beams in place one by one, and at the same time equalize the distances between them.

Step 5. Screw the boards to the mauerlat using self-tapping screws.

Stages of installing a roof for an extension

In order for the house to have a more original appearance, additional building elements are often used - extensions that will allow you to spend leisure time or gather the family around a large dining table. The extension can be created during the construction of the house or upon its completion. Also, very often a veranda, terrace or other type of extension is used for houses that were built a long time ago. In this case, you will have to think about how to protect the additional room from the influences of nature, its vagaries in the form of snow or rain.

Types of roofs and types of roofs

A well-thought-out exterior of a private house will create a pleasant impression both for the home owner and for his friends or neighbors, because the external perception of the house determines an opinion about its owner. Ideally, the design of the house and the extension should match each other and fit together correctly.
To make this possible, it is necessary to use a single roofing material, both for the house and for the extension to it. An exception to the rule would be glass extensions for a dining table with a view of the environment or a greenhouse. In this case, the roof should also have a transparent appearance, regardless of the house and its covering.
It is necessary to understand the specifics of the words, to understand their essence, since the roof is the upper part of the house, a structure that contains layers of thermal insulation and waterproofing. In turn, the roof is a decorative covering that protects the roof from precipitation.

The choice of roofing materials for an extension depends on several factors:

Functional role of the room.
Extension architecture.
Construction materials used in the construction of a house.
Roof roofing materials.
