Step of self-tapping screws on metal tiles. Do-it-yourself metal tile installation: step-by-step installation of a metal tile roof

IN Lately most of private low-rise buildings being rebuilt are covered with metal tiles. This practical and durable coating provides reliable waterproofing throughout the entire life of the roof. If the fastening of metal tiles to wooden sheathing is done correctly, then load bearing capacity the structure will be so large that it will withstand the load from a three-meter snow layer without deforming. In this article we will talk about important features fixing profiled steel sheets to the base of the roof, affecting its quality and strength.

Metal tiles - common roofing, which is rectangular sheets of profiled steel. Zinc coating and polymer protection help this material retain its qualities when in contact with water, preventing corrosion. Many inexperienced craftsmen have a question about how to properly attach metal tiles to the sheathing, as well as what tool to use for this. Manufacturers note the following features of working with this material:

1. To cut metal tiles, it is not allowed to use abrasive tools, when used, the surface of the material heats up, burning out the polymer coating. For this reason, you cannot cut metal tiles using a grinder or attach sheets by welding.
2. Use cutting tool, a drill or a screwdriver for processing metal tiles must be used at low speeds so as not to damage the material, as well as to make the edges smooth.
3. When tightening self-tapping screws with a screwdriver, it is necessary to clearly determine the required pressure force, since with excessive force the coating is deformed, and with insufficient force it is poorly fixed to the sheathing.

Important! Fastening metal tiles is a technologically quite simple process, which requires special fasteners, as well as a powerful screwdriver powered by rechargeable batteries.

Lathing requirements

The profiled steel sheets used to cover the roof have a rigid shape, so they are attached to conventional thin sheathing.

• This roofing covering is highly durable and light weight, so it does not have any special requirements for base preparation. To simplify the process of fixing metal tiles to the slope, the following rules must be observed:
• must correspond . If the distance between the base slats is the same as the wavelength of the coating, then where and how to attach the metal tiles will be much easier to determine.
• The permissible pitch between the sheathing elements is 30-70 cm, however, it must correspond to the roof slope. The greater the angle of inclination of the roof, the less snow accumulates on the surface of the slope, the less often the sheathing slats can be attached.

In the area of ​​the roof overhang, where snow guards are attached to the roof, as well as in the area of ​​the ridge connection, the sheathing is reinforced with additional boards. In addition, the places where snow accumulates most actively (valleys, gutters, joints with vertical surfaces) need to strengthen the foundation. Please note that for the manufacture of sheathing for metal tiles it is better to use edged board or bars square section , planed and processed antiseptic drugs

. The smoother the base on which the roofing covering is attached, the easier it is to fix it with self-tapping screws.

Requirements for fasteners

1. Before attaching metal tiles, you need to choose the right and high-quality fasteners. Fixing steel profiled sheets to the sheathing is done using self-tapping screws, which, when screwed, drill a hole in the material using a sharpened, sharp tip.
2. In this case, for high-quality fastening it is necessary to use fasteners that meet the following criteria:
3. To fix metal tiles, special roofing screws are used, which are made of galvanized steel. Such fasteners are more expensive, however, they do not rust when in contact with water, due to which the coating lasts longer.

Note! To securely fasten a sheet of metal tiles to the roof, it is necessary to use roofing screws, the length of which is 1-3 mm greater than the total thickness of the roofing material and waterproofing.

Number of attachment points

Even experienced professional craftsmen have disputes about how many fastening points are needed to firmly attach a sheet of metal tile to the sheathing. On this score, as they say, there are so many people, so many opinions. In this situation, the proven principle “the more the better” does not work, since in this way you can only deform the sheet.

• When fixing metal tiles, manufacturers advise adhering to the following standards: For every square meter of roof area you need 8-12.
• roofing screws
• Additional elements are fastened with 3-5 screws per linear meter.
• The metal covering in the area of ​​the end and roof overhang must be attached to each batten of the sheathing, that is, every 30-40 cm. They also increase the number of attachment points in complex structural elements

roofs - valleys, valleys, places where the coating adjoins vertical surfaces.

It is believed that when fixing a metal roof, self-tapping screws should be screwed into the center of the lath. In any case, the attachment point should be located further than 1.2-2 cm from the edge of the board.

Fixation scheme The correct scheme for fastening metal tiles with self-tapping screws guarantees reliable fixation roofing covering on the surface of the slope, which will not weaken under intense wind loads. On every

1. square meter
2. roofing material must have at least 8 evenly distributed attachment points in accordance with the following rules:
3. The screws are screwed in strictly at right angles to the roof surface so that the press washer closes the mounting hole.
4. Do not tighten the roofing screws all the way so as not to deform the covering. It is necessary to leave a gap of 0.5-1 mm between the head of the fastener and the surface of the material.
5. The screws are tightened at a distance of 10-15 mm from the stamping line between the ridges of the metal tile.

In places where one sheet of metal tile overlaps a second, screws are screwed into both layers of roofing material at once, so that there is no gap between them where water can penetrate. Fastening the metal tiles begins from the lower right edge of the slope, and ends with fastening the ridge. which prevent water from penetrating under the roofing material.

Video instruction

If the tile covering is installed incorrectly, the service life of such a roof is significantly reduced. We propose to consider how metal tiles are fastened to the sheathing with self-tapping screws, a diagram for installing sheets, as well as how installation is carried out end strip(wind).

The principle of installation of tiles

Installation of this roofing is carried out using standard construction screws. The use of nails is extremely undesirable, because under impact loads, the layers of metal tiles disintegrate, which is why construction material is destroyed.

Roofing screws are used for installing corrugated sheets, boards, metal tiles and other materials. Externally, they look like steel screws, often made of alloy material. The surface of the screws is coated with a layer of zinc to better resist corrosion processes. The head of the screws has a hexagonal shape. Thanks to this geometry of the product, the load is distributed evenly over the surface of the metal tile sheet.

Photo - correct and incorrect fastening of metal tiles

There must be a flat ring or gasket under the head. This part protects the roof surface from scratches and corrosion. Also, thanks to the gasket, depressions or dents do not form on the roof after installation of the covering. Self-tapping screws can be selected with different metal alloys, colors, head sizes and lengths. All these parameters must be agreed upon with the engineer who calculated the roof. But always pay special attention to the washers; they must be made of a durable rubber compound.

The shelf life of fasteners, like metal tiles, is within 50 years. In this case, it is very important to strictly monitor the gasket. If the washer is made of low-quality material, the metal under it will begin to rust before the time specified by the manufacturer, which can cause damage to the entire surface of the roof.

How to mount correctly

When you have already decided on the material and purchased fasteners, you can begin installing the roofing material. To properly attach metal tiles to the roof with your own hands, you need to use advice professional builders:

1. Make sure that the washer is in the upright position, was not pinched and did not protrude upward;
2. In order to install the metal tiles evenly on the sheathing, you need to use guidelines. It is not convenient for everyone to mark the installation locations of screws on each sheet; many professional builders advise to navigate by the previous step of metal tiles. By stepping back from it a couple of centimeters, you will ensure simple and beautiful installation material;
3. Use a screwdriver - this will significantly speed up the installation process;
4. Screw the screws into the lower parts of the wave; when installing fasteners on the ridge, you may not be able to reach the sheathing with the screw, which will lead to a decrease in the rigidity of the roof;
5. The self-tapping screw must fit into the roof frame at least two centimeters. This is very important both for the rigidity of the surface and for its tightness. With this supply, you will close the holes into which the screws and washers were screwed and ensure the dryness of the under-roof space.;
6. Check all connections carefully, otherwise when there are gusts of wind they will knock heavily on the roof and may even come off and cause damage.

Instructions on how to attach metal tiles:

1. Install the first sheet of metal shingles level with the end strip. It is along this part of the roof that the leveling is carried out;
2. Then, using a screwdriver, connect the covering and the rafters. It is very important that the self-tapping screw goes into the rafter board to a depth of 2 centimeters. To do this, choose screws with a length of 60 millimeters;
3. On any metal corrugated covering you need to attach up to 8 pieces of self-tapping screws. A smaller amount will increase the likelihood of a decrease in fastening strength, and a larger amount will significantly reduce rigidity;
4. Sheets of metal tiles are mounted in the direction from the base to the ridge or top of the grid;
5. At the end of the work, treat the joints between the screws and the roofing with a special mastic. This will help protect them from corrosion if the surface of the metal tiles is damaged. Before purchasing such a product, be sure to consult with sales consultants. Some types paint and varnish materials harm the polymer top layer of tiles, reducing its resistance to aggressive external factors.

There are several secrets that help when installing metal tiles. For example, for perfect evenness of the cornice strip, it is important to install the very first row of sheets with high quality. The parallelism of other sheets depends on its geometric accuracy.

The fastening points for metal tiles must be at right angles to the roof. This scheme helps ensure the tightness and durability of the connection. Also, thanks to such connections, a jagged surface (cascade) is formed along the purlins, which prevents snow from falling from the roof surface.

Hidden mount

Nowadays, metal tiles with a hidden lock are also used quite often, for example, Monterrey. It is considered more aesthetic, but the process is also more labor-intensive. For such an installation, a special metal tile is required, which is equipped with special holders.

The procedure for attaching metal tiles with a hidden connection:

1. Install holders on the sheathing that will serve as a support for the tile sheets. They need to be mounted on the very first eaves beam. The optimal pitch of the holder along the rafters is 250 mm;
2. Now, without using additional screws, hook the sheet of metal tile onto the holder and lightly press it until it clicks. At correct location the first row, the rest will not need adjustment or alignment;
3. To install further coverage, you will need self-tapping screws. They need to be mounted on the roof in special places indicated by depressions on the sheets of metal tiles;
4. After this comes a row of tiles, which are secured using special Z-lock “locks”. They are located in designated areas, their location is marked with special marks, which you can find in the instructions for a specific brand of roofing;
5. After this, the standard fastening of the ridge of the metal tile is carried out.

It should be noted that this method of installing roof coverings is more practical and safe than standard installation self-tapping screws. The minimal use of bolts can significantly extend the life of the roof and ensure the required rigidity and strength of the coating. Such materials are sold in company stores.

With this installation option, the accuracy of fastening the wooden wind strip and metal tiles is also very important. It is worth remembering that before starting roofing work it is necessary to install gutters and other drainage elements. For the beauty of the facades, we advise you to cover the open space below with planks after finishing the work.

But at the same time, the snow retainers are attached to the metal tiles after the sheets are installed. The technology is simple: in certain places you need to make holes in the roof, and then install additional elements on it using a screwdriver. This way you can install roofing material on the roof of a house, garage or veranda.

In many ways superior to other types of roofing, such as slate, galvanized sheet, bitumen shingles and so on. Laying the material is usually trusted to specialists, but if you wish, you can install the metal tiles yourself.

Advantages of the material

TO strengths metal tiles include:

The only disadvantages include increased noise during precipitation, but this can be solved by installing a layer of glass wool.

Covering the roof with metal tiles begins with calculations.

Stage 1. Carrying out calculations

Let's make one thing clear first important point. Visually, a roof covered with this material consists of rows and waves (the first run across the slope). The distance between the rows is called the pitch. If a sheet of tile has a pitch of 35 cm and six waves, then it is called a module. Modern market building materials offers sheets for 1, 3, 6 and 10 modules.

Important! If you wish, you can order tiles in individual sizes, but this will cost much more. It should be remembered that the length of the sheet should not exceed 7 m and be less than 45 cm.

When calculating and laying out, the fact that joints and waves should form a solid coating along the entire length of the slope is taken into account. Having decided on the number of modules, the amount of material is calculated based on the roof area.

In addition to the metal tiles themselves, the kit also includes:

• steel strips 2 m long;
• steel sheets 200x125 cm, having the same color as the tiles.

Typically, the strips are intended for roofs made with a slope of 30ᵒ, although if desired, you can adjust them to 11-70ᵒ.

Important! Minimum slope, at which installation of tiles is allowed, is 11ᵒ.

Stage 2. Preparing everything you need

To install tiles, you need the following equipment:

• metal scissors;
• ladder;
• electric drill;
• long rail;
• screwdriver;
• mounting tape;
• measuring device;
• hammer;
• marker;
• personal protective equipment (mittens, plastic glasses).

You will also need the following consumables:

• waterproofing;
• tiles;
• roofing strips;
• aero roller;
• trims for ends and ridge;
• decorative overlays;
• self-tapping screws, sealing washers and for them;
• boards 2.5x10 cm;
• guide board.

Stage 3. Foundation

As noted earlier, metal tiles weigh little, so they do not need a reinforced base - you will need a regular sheathing of wooden slats. The pitch of the sheathing should be calculated according to the dimensions of the tiles, so as not to drive the screws into the void during installation.

Stage 4. Thermal insulation

Thermal insulation is necessary not only to prevent heat loss, but also to protect against the noise of rain. First, the rafters are covered with a vapor barrier material (for example, Izospan or Yutafol). Next, an insulating layer (no more than 25 cm thick) is laid, covered with an antioxidant film and attached to the rafters with wooden blocks.

Important! The material between the bars should sag slightly (about 2 cm) so that the condensate flows only into the drain.

Stage 5. Installation of tiles. Basic Rules

1. can be done in one of two ways. If the stacking of sheets begins on the right, then each new one is superimposed on the previous one. If it’s the other way around, then the previous sheets are superimposed.
2. In order to ensure correct installation, four sheets of tiles, located overlapping relative to each other, are first grabbed, aligned, and only then finally connected with one self-tapping screw.
3. Self-tapping screws must be of high quality, because the service life of the roofing largely depends on them. These must be galvanized screws with sealing heads made of propylene rubber, hermetically filling the hole when tightened.
4. A thickening appears at the junction of the four sheets. It needs to be removed, for which part of the corner is cut off or the capillary ditch located under the stamping line is straightened.

Stage 6. Individual elements

Step 1. The end strips are fixed with an overlap (about 2 cm). The size of the wave is adjusted to the width of the slope, otherwise the crest may fit on the pediment.

Step 2. A roofing strip is added, then an additional sealant is placed between it and the sheet of material.

Step 3. When arranging pipes or windows that are located below the ridge, sheets with one module are taken - two pieces for each structural element.

Step 4. For sloping slopes, an aeroroller is installed between the material and the ridge strip, which will prevent precipitation from penetrating under the ridge.

Step 5. The ridge is fixed on the strips located at the ends of the structure. This must be done in such a way that it protrudes by 2-3 cm. In the case of a flat ridge, all elements are attached with an overlap, and if it is semicircular, then only according to the profile lines.

It is also worth noting that, if necessary, the ridge strips can be bent and unbent so that they follow the angle of the roof.

Stage 7. Arrangement of the valley

An additional board is attached to each valley. Installation in this case starts from the bottom and is carried out with an overlap of 25-30 cm. Below the level of the cornice, the bottom strip is cut off and flanging is made along it. A sealant is placed under each trim and ridge.

There is a gap between the axle and the sheets (at least 8-10 cm). Screws are screwed into the cut sheets one and a half centimeters from the stamping line. However, when fixing, the fasteners are made 25 cm from the axis of the valley. If everything was done correctly, then upon completion of the work the sheet at the fastening point will be in contact with the board where the valley is located.

Important! If mistakes were made, the fastening will be located in other places and, as a result, gaps will form on the surface through which the roof will leak.

To cover the cut sheets, decorative overlays are used, when installing which you need to remember some important points:

Often the beginning and end of the valleys are on the roof slope. Let's take, for example, editing dormer window. Here a separate board is placed under the valley. For the window itself, a cutout is made in the sheet, and sealing material is laid along the walls. In this case, the eaves overhang is covered with a plank.

Then the valley strips, previously cut at the edges, are fixed. The released part should adhere extremely tightly to the tile sheet.

Slopes in the form of a trapezoid or triangle

If the roof slopes have a trapezoidal or triangular shape, then it is necessary to install additional bars.

Step 1. The bars are attached on both sides of the “ridge” along the fold line of the roof.

Step 2. The cornice board is installed and assembled.

Step 3. The cornice system is being constructed.

Step 4. The tiles are laid. This is done along the line of one of the edges or the axis. The first sheet is aligned with the cornice strip.

Important! It is unacceptable that the distance between the cut corner sheets installed near the “ridge” be more than 10 cm.

Step 5. To install the ridge assemblies, perform the following steps. The ridge strips are aligned with the angle of the “ridge”. If a straight ridge is used, then it is cut according to the corners, and if it is semicircular in shape, then the installation of an additional plug (preferably plastic) will be required.

Step 6. The ridge strip lies strictly along the axis of the “ridge”. This is quite simple to do if the angles of the slopes are the same, but if they are different, then it is correspondingly difficult. To control the junction of the slopes, bright-colored mounting tape is used.

Features of material care

As already mentioned, metal tiles are covered with a polymer layer that protects against corrosion. But constant exposure to ultraviolet radiation, precipitation and dust sooner or later causes the destruction of the protective layer. That is why metal roofing should be cleaned regularly.

1. Dirt and dry leaves are washed off with a damp fluffy brush.
2. To remove more complex stains, you can use special cleaning products for polymer surfaces.
3. Do not use aggressive chemicals– they can destroy the protective layer.
4. Gutters are cleaned with a stream of water under pressure. The jet must be directed from the ridge to the eaves.
5. To clear the roof of snow, you can use only those tools that, in principle, are unable to damage the coating.

If all these rules are followed, it will last about 50 years.

Standard metal tiles are profiled sheets of galvanized steel, which have a double-sided polymer coating and have excellent performance properties. Installation work using metal tiles differs in some nuances, among which an important factor is the correctly executed sheathing.

Installation of sheathing

Under the metal tile covering is a base for direct installation of the roofing covering. In accordance with the weight of this roofing material, the installation of metal tiles must be preceded by the formation of a reliable and fairly durable flooring.

The main stages of installation of the sheathing:

• selection of rafter beams with a cross-section of at least 5x15 centimeters, and for sheathing - use of boards with a cross-section of 2.5x10 centimeters. The counter-lattice is made from a board with a cross-section of 2.5x5 centimeters;

• rafters are laid in optimal increments of 60-90 centimeters;

• fastening the initial board along the length of the eaves overhang. The thickness of the starting board should be 1.5 centimeters greater than subsequent boards, which will compensate for the difference in the levels of the support points of the metal tile segments;

• the distance between metal tile boards is from 35 to 45 centimeters;

• the correctness of the distance between the starting and subsequent sheathing boards is checked using board scraps;

• all markings are based on tape measure readings;

• the next step is to attach the end and ridge strips;

• the wind board is mounted above the sheathing and corresponds to the height of the metal tile sheet;

• reliable fastening of the ridge is based on the installation of additional boards with a cross-section of 2.5x10 centimeters at the points of its attachment.

What and how to screw in self-tapping screws correctly

Despite the popularity of metal tiles, not all consumers know what fasteners are used when installing roofing sheets. The sheets are fastened using self-tapping screws, which are distinguished by the presence of a washer with an elastic seal. Positive points is the ability to choose the color fastening elements to match the main roofing covering.

A special feature of fastening sheet metal tiles is the fastening of roofing screws to the lower segment of the wave, at the point of contact of the metal with the sheathing. The fastening elements must fit twenty millimeters into the sheathing frame.

However, care must be taken to ensure that the backing fills the entire space between the roofing metal and the head of the fastener and washer. Careful adherence to this rule will allow you to obtain an impermeable connection based on vulcanization of the substrate. The length of the screws should not be less than 2.8 centimeters.

It should be taken into account that the first roofing sheet is laid along the eaves line, and the installation of metal tiles always begins from the left and lower corner of the roof. In addition, a prerequisite is to fasten the screws from the bottom up, which allows the top sheets to cover the bottom ones.

Scheme for fastening sheets of metal tiles with self-tapping screws

It is quite simple to do if, when performing it, you fasten the material according to the following scheme:

• installation of cornice strips;

• installation of the lower valley;

• arrangement of internal pitched connections to chimney pipes, walls and other vertical surfaces;

• direct installation of metal tile roofing sheets;

• installation of the upper valley;

• installation of upper adjacent strips;

• securing the end strips;

• installation of ridge strips and external corners;

• installation of ventilation and passage elements;

• arrangement additional elements safety represented by ladders, transition bridges and snow retainers.

Particular attention should be paid general rules, compliance with which allows you to produce the correct and high-quality installation metal roofing:

• screws must be screwed into the lower segment of the wave crest;

• in order to level out the largest wind load, which usually falls on the edge of the roofing, fasteners should be placed above the steps, and screws should be screwed in at a distance through the wave;

• the rest of the roofing sheets are equipped with self-tapping screws minimum distance from the step, which allows you to make the screws less noticeable;

• for the tightest possible fit of the roofing sheets to the sheathing, central part fasteners must be shifted by five centimeters at the point where the overlap occurs. On the upper roofing sheets this rule applies close to the overlap, and on the lower ones - a little further than the overlap.

Technology and procedure for installing roof units

Especially often in modern roofing work the installation is used cornice unit with a leaf protrusion of five centimeters. This method allows rainwater to fall directly into the gutter, and elements made of wood are protected from splashing water. According to standard instructions self-tapping screws are screwed through the wave at a distance of seven centimeters from the stamping line.

It is possible to install this unit by placing a standard metal tile cut on top of the eaves board, which is convenient when performing roofing work in conditions of stepped eaves or violations of the roofing geometry in this section of the roof.

The ridge strip is fastened using self-tapping screws at the highest points of the metal tile sheets. The spacing between fasteners should not exceed 80 centimeters. All fastening points should be located with the same spacing in the sheathing, which will prevent deformation of the ridge strip when tightening the screws.

When attaching the end part of the slopes, fasteners should be mounted on each wave of roofing material in the places of the standard points. To fasten the end strip, the highest points of each sheet of metal tile are fixed through a wave with a step between fastenings of no more than 80 centimeters.

For more information on how to properly screw in the screws yourself, watch the video.

The need for additional fastening with self-tapping screws

The main task of using additional fasteners is to ensure resistance to significant wind loads, which always requires the provision of high-reliability fastenings in the most significant areas.

Fastening additional screws for fastening metal tile sheets to each other:

• self-tapping screws along the waves;
• with self-tapping screws in rows.

Fastening metal tile sheets with self-tapping screws to the sheathing:

• along the eaves line;
• along the ridge line;
• The roofing sheets are fixed to the boards along the end line using self-tapping screws.

Features of installation with hidden fastening

The most popular method of fastening metal tiles is hidden fastening, which involves the use of self-tapping screws with a press washer. Due to the fact that the fasteners will not be noticeable from the outside, the use of unpainted galvanized self-tapping screws is allowed.

The main difference between such installation with hidden fastening is that there is no need to equip through holes in the sheets of roofing material. The entire process of screwing fasteners is carried out into special grooves. To connect individual roofing sheets to each other, special hooks are used that are attached to the mounting lugs.

As a result of this fastening, the screws are hidden under the subsequent metal tile sheet. A feature of metal tile roofing made using hidden fastening is the ability to obtain a roofing covering that differs high degree strength and tightness.

Let's sum it up

• If installation work started from the left side of the structure, then all roofing sheets, after fastening, should be placed under the outermost wave of the previous roofing sheet;

• After securing the starting sheet near the ridge using a self-tapping screw, the next sheet is laid to obtain a perfectly straight line at the bottom. The resulting overlap is fixed using one self-tapping screw along the wave crest;

• To fasten metal tile sheets at the level of internal joints, standard groove strips should be used. It is necessary to control the size of the overlap, which should not exceed fifteen centimeters;

• to perform proper fastening, short screws should be screwed into the lower segment of the wave;

• Screwing roofing screws into the upper wave segment contributes to an insufficiently tight fit of the washer to the metal and reduces the tightness of the roofing.

Using metal tiles allows you to create a durable and beautiful roof that requires minimal maintenance. The installation of metal tiles is not particularly complicated, which allows you to do this type of work yourself. In this article we will talk about how to properly attach metal tiles.

General information about metal tiles

Metal tiles are a roofing material that is made from steel sheets coated with a special polymer coating. Thanks to a special stamping technology, the resulting sheets take on the appearance of natural clay tiles.

The following definitions are accepted in the lexicon of builders:

• “waves” - transverse rows of tile profile;
• “rows” - longitudinal profile;
• “tile pitch” is the distance between rows.

The most common version of metal tiles on the market are sheets with a width of 1180 mm, while the working dimension is 1100 mm. The remaining 8 cm is used to create an overlap. In most cases, the pitch of metal tiles is 350 mm, but other sizes are possible.

The bottom cut is located 5 cm from the edge of the stamping. The length of the segment between the top edge of the sheet and the top cut depends on the length of the sheet itself. The most common brands of tiles have a shaped cut, which is located 5 mm below the stamping line.

To successfully complete the fastening work, in addition to the metal tile itself, you must purchase the following:

General rules for fastening metal tiles

Let's consider general principles how to attach metal tiles to the roof:

Also, novice builders often make mistakes in fastening sheets of metal tiles. So, instead of screwing short screws into the bottom point of the wave, the screw is screwed into the top point. As a result, the washer does not fit tightly enough to the metal and, thus, the tightness of the roof is reduced.

IN general case does not present any particular difficulties. But it is still necessary to take into account the rules for fastening metal tiles and the manufacturer’s recommendations. And then you with my own hands you can create a roof no worse than the one shown in the photo.
