Installation of modular metal tiles. Modular metal tiles. What is a modular metal tile with hidden fastening?

Modular metal tiles have a number of features that distinguish them from standard metal roofing tiles. The advantage of this type roofing is, first of all, ease of installation. Individual modules of profile metal sheets have small area, so their installation can be carried out by one person. In addition, many manufacturers of modular metal tiles provide special grooves on the surface of the sheets at the points of their contact. This provides correct formation flat roof.

Installation modular system roofing covering is convenient on roofs with a complex structure of slopes. An example would be a multi-pitched roof with skylights, several chimneys, terraces and balconies. The small size of individual modules ensures their versatility, mobility and compatibility with any structural elements and building components.
Each sheet also has holes for connecting the roofing elements to each other. The mounting points in most cases have small recesses around the holes, which ensure tightness and tight fit of different modules to each other. However, it should be noted that the presence of such convenient and useful options increases the final cost of the product. In addition, one more thing should be noted distinctive feature modular design elements. This is a special bend on the leading edge of the sheet, which ensures its stability against the influence of gusts of wind or other atmospheric phenomena.
One more an undeniable advantage This type of metal tile is a significant reduction in waste when installing a multi-pitched roof. Combining entire modules with their sections, as well as many options for their location, allows you to achieve the best indicator of rationality when assembling the roof covering, and installation individual elements
will be prompt and convenient. Also, given the compactness of this type of roofing material, we can talk about significant savings on delivery. Products are stacked on standard and its transportation does not require the services of large-sized freight transport and a manipulator.

Necessary tool

Installation of a modular design will require the same set necessary tools, as the assembly of a roof made of classic sheet metal tiles. So, to carry out the work you will need:

• Electric cutting shears;
• Cordless or corded screwdriver;
• Hand scissors for metal;
• Construction stapler and a hammer;
• Mechanical tape measure, construction marker and horizontal level.

It is prohibited to use corner grinding machines with abrasive discs for cutting sheets of modular tiles. In addition to the above, you need to worry about personal safety. To do this, you should have comfortable construction gloves that will protect your hands from cuts from the edges of sheets of roofing material. It is also recommended to wear safety glasses when cutting with nibblers to avoid getting caught in small pieces of metal. Installation without protective equipment may result in serious injury.

Installation

As noted above, the installation of modular metal tiles is practically no different from the technology for laying classic-format metal roofing tiles. The only exception is the connection of individual modules to each other at the ends of the outer waves of the canvas. Considering small sizes modules, when lifting them onto the roof of a building, it is necessary to ensure proper retention of a separate roofing element in hand. You need to grab it from the top and bottom edges. Grasping from the sides can lead to deformation of the sheet due to the more flexible bending structure of the metal in the vertical plane.
Many manufacturers of such roofing systems in their installation instructions recommend installing the first batten of the sheathing with a height of 30 mm higher than the subsequent ones. The starting sheet of modular metal tiles is fixed on the lower right side of the roof slope. To do this, you need to secure it with two roofing screws.
The correct sequence of laying sheets of modular metal tiles affects the comfort of such work and the overall speed of installation. After laying the starting sheet, the second module is located to the left of it on a horizontal plane, the third sheet is covered above the first, and the fourth, respectively, above the second.

Installation additional elements metal tile covering, such as eaves, end and ridge strips, bypass elements, as well as structures to ensure the safety of movement on a metal tile roof, is carried out according to standard rules and technology.

The design of the modular metal tile sheet provides for the presence of ready-made holes for self-tapping screws on the end side, which greatly facilitates installation work. First, the touching elements are connected to each other along the edge, after which they are fixed over the entire surface. Self-tapping screws must be screwed in directly under the wave. On average, one sheet with two rows of waves should use at least 4 screws that secure the sheet to the sheathing.

Technical and operational characteristics

The average service life of modular metal tiles, stated by many manufacturers, is approximately 50 years. Depending on the thickness of the material used, the average weight of one sheet is about 5 kg per 1 sq.m. Thus, the average weight of one sheet ranges from 2.5 to 3.9 kg. This is precisely what argues for the possible self-installation without the involvement of assistants or the use of special lifting equipment.

Types of modular metal tiles

One of the most popular and popular models metal tiles of this format are “Venecja” of the “Bud Mat” brand. The dimensions of one element of this type of roofing material are 1150 mm covering width, the pitch of the tile itself is 350 mm, the total width of the sheet is 1190 mm, and its length is 736 mm. At the same time, the height of the Venecja metal tile profile is 26 mm, and the weight of one sheet is 3.7 kg. Also among the modular types of metal roofing, it is worth noting the “Tigula” trademark, which is in turn divided into “Maxi” and “Mini” subtypes. The first version is relatively standard in its dimensions, which are 1116 mm wide and 751 mm long. The profile height is 72 mm. Compared to the “Venecja” type, this metal tile model has a more rounded profile. The pitch of the tiles is also 350 mm. The modular metal tiles of this brand of the “Mini” type have smaller dimensions in length, which are 410 mm with a covering width of 1000 mm. Moreover, its design provides only one row of waves, which is convenient for completing the missing sections of metal tiles.
Installation of Monterrey Super metal tiles is also popular modular type. These products have demonstrated some of the best performance in terms of operational characteristics. The useful or covering width of one module is 1100 mm and the length is 700 mm. total area one sheet of Monterrey Super is 0.8769 sq. m., while the useful (covering) indicator is 0.77 sq.m. Correct installation and periodic maintenance of the roof will ensure a long service life. At the same time, the absence of any noticeable color changes is guaranteed. protective coating metal tile sheets for a long time. Thus, the Pruszynski company provides a 30-year guarantee for its modular metal tiles “Arad”, “Kron” and “Karpatia”, and more famous manufacturer modular metal tiles trademark Ruukki provides an even longer guarantee of 50 years for Monterrey Premium pural coatings.

Recently, metal tiles have been increasingly used for roofing. The material is supplied in the form of profiled sheets with a polymer coating. If you wish, you can install the metal tiles yourself. Step-by-step instructions will help you do this without serious mistakes.

Work on laying roofing fragments

The products are based on a steel sheet with a thickness of 0.45-0.55 mm. It is galvanized and has a special polymer-based coating. The cost of production may vary depending on the thickness of the metal and the type of protective layer.

List of advantages

First of all, it is necessary to highlight the following advantages:

• aesthetic appeal;
• weather resistance;
• affordable price;
• lightness of the main elements.

Note! Polymer coatings perform not only a protective, but also a decorative function, since their colors can vary over a fairly wide range.

Few disadvantages

Since the sheets have a small thickness with sufficient large sizes, the risk of damaging them during careless installation still exists. If all the rules are followed, the integrity of the elements is difficult to violate.

Another disadvantage is the appearance of a noise effect in heavy rain during operation. However, with proper soundproofing of the living space, this disadvantage is completely eliminated.

Tools for installation work

It is necessary to prepare in advance a set of tools and additional devices for the work:

Note! It is forbidden to cut sheets using abrasive wheels, since high temperature exposure leads to the destruction of not only the polymer, but also the zinc layer.

Basic set of additional parts

IN step by step instructions for the installation of metal tiles, the main elements used in conjunction with the sheets should be mentioned. They are used depending on the roof configuration and operational features.

We suggest taking a look at the list of basic parts:

• a ridge is required to close the upper joint between two slopes;
• the end strip is necessary to decorate the edges on the side of the gable overhangs;
• the valley is installed in the places where the slopes combine;
• the cornice strip is attached to the side of the gutters;
• the junction strip is mounted in the presence of a pipe and other protruding structures;
• A snow retention element is needed to prevent snow from sliding off the roof.

Instructions for installing metal tiles: step-by-step work

Loading and unloading of products can be done manually, but during the work a certain number of people must be involved. Usually 1 person is required for 1.5-2 linear meters sheet length. That is, when unloading metal fragments with a length of 6 m, 3-4 people should be present.

Waterproofing device and fixation of control bars

If thermal insulation is laid between the rafters, then waterproofing material must be present in any case. It is attached with brackets to the load-bearing part of the roof. The canvases are spread across the rafters with an overlap of at least 15 cm along all slopes.

50x50 mm bars are nailed directly onto the rafters, ensuring ventilation gap between waterproofing and roofing material. For fixation, nails of at least 90 mm are used.

Correct installation of sheathing under metal tiles

An edged board 25 mm thick and 100 mm wide is usually used as lathing, but the final choice will depend on the pitch of the rafters. The elements are attached to 50x50 mm bars using nails no less than 70 mm long. The distance between the boards depends on the wavelength of the metal tile used.

At the installation location ridge element It is recommended to install two planks close to each other. This will simplify the installation of the ridge on the metal tiles. The same should be done at the places where the valleys are attached. The bottom board of the sheathing should be higher than the others by the height of the wave. Usually the thickness of the lining is enough to compensate for the difference.

Installation of parts mounted to sheets

To protect the ventilated space under the roof from the penetration of moisture and street debris, installation is carried out cornice strips metal tiles. A ventilation tape must additionally be attached to the ends of the 50x50 mm bars.

When installing the valley, a universal seal is laid. The bottom edge of the element should be on the surface of the cornice board. When joining horizontally, an overlap of at least 30 cm is made.

Lining a brick chimney involves extending the waterproofing membrane by at least 50 mm. A groove is made in the pipe itself, the depth of which should be at least 15 mm. Water is discharged into the valley located in the immediate vicinity.

The process of laying and fastening sheets

All sheets must be aligned horizontally with an extension of 50 mm beyond the sheathing. When fixing metal elements the following points should be adhered to:

• the self-tapping screw must be installed in the deflection of the wave, where the sheet is adjacent to the sheathing;
• fastening to the bottom board is carried out above the step directly through the wave;
• Along the edge of the slope, fasteners are screwed into each wave.

Installation of end strips and ridge

Elements for closing the end joints are mounted in the direction from the eaves overhang to the ridge. The overlap on adjacent planks should be 10 cm. The recommended spacing between fasteners is 35 cm.

As for the skate, it is fixed to the upper crest of every second wave. When building up elements, an overlap of at least 15 cm is left. Self-adhesive sealing tape is attached along the entire length.

Additional instructions for installing snow guards on metal tiles

The number of elements to hold snowdrifts on the roof is selected taking into account the geometry of the roof. In areas of heavy snow scraping, two rows can be installed metal profiles. Pass-through type snow guards are optimal solution for individual buildings. They are attached using long screws to the sheathing itself through . The distance between fixation points usually ranges from 50-100 cm.

Metal tiles are considered one of the most popular roofing materials. It can be seen on construction sites of large public buildings and during the construction of small private houses. Everywhere they appreciated the durability, reliability and attractive design this material. So that the roof, after all the work, fully complies with the best technical specifications, it is necessary to install a metal tile roof on professional level. To do this, you will have to thoroughly study all stages of the work.

The first step to installation work– this is an acquisition required quantity roofing material. If we're talking about about metal tiles, then it’s worth doing everything first necessary calculations so as not to make a mistake when purchasing.

Metal tiles differ from many roofing materials in that they have a clearly defined direction, that is, the sheet can only be used in one direction and swapping “top” and “bottom” is unacceptable. This fact leads to slight difficulties in calculations, since there are fewer possibilities when cutting.

Metal tiles are measured in modules, that is, in sheets with certain dimensions. The module consists of six horizontal waves with a pitch between vertical rows of 350 mm. On construction market you can find sheets with parameters in one, three, six or ten modules.

Important ! Unlike other types of roofing, which have standard sizes, metal tiles can always be made “to order”, taking into account the specific dimensions of the roof of the house under construction.

When calculating the number of sheets, you can use a special calculator, but it is better to work with ready-made drawings of the roof of the house. On them, to scale, it is worth placing the sheets so that cutting waste is minimal. For better design It is worth taking into account all the requirements contained in the installation instructions for metal tiles.

The work is carried out in strict sequence and is divided into six stages:

1. Assessment of the geometric clarity of the roof and preparation of metal tile sheets for installation.
2. Installation of waterproofing.
3. Manufacturing and installation of sheathing.
4. Arrangement of layers " roofing pie».
5. Taking measurements and cutting sheets.
6. Installation of sheets of roofing material.
7. Work on installation of additional roofing elements.

Laying metal tiles involves the sequential formation of all roofing layers

In addition, working with metal tiles requires precise knowledge of which tools are acceptable to use and which are best avoided.

Rules for cutting sheets

Metal tiles have a protective polymer layer over the entire surface. Any damage to it inevitably leads to the development of corrosion and a reduction in the service life of the roofing material. This can only be avoided by following a number of rules:

Having planned the location of the metal tiles on the roof of the house and made sure that you have the necessary tools, you can proceed to the installation procedure itself.

Preparatory stage

Before covering the roof with metal tiles, it is necessary to critically assess the condition of the roof itself and prepare it for the start of work. Conventionally, preliminary measures can be divided into the following actions:

• Removal of old hard roofing, if any;
• Exiting all smoke, ventilation and other penetrations through the roof;
• Completion or stop of façade finishing work.
  

  Important ! Removing splashes of paint and other solutions from a layer of metal tiles can damage the protective layer of the sheets, as well as deform the roof surface.

• Check the geometry and dimensions of the roof: measure the diagonals of the slope and make sure there are no irregularities on the surface.
• Check the angle of the roof. The standard tilt value must be at least 14 degrees; in rare cases, it is allowed to carry out work at 11 degrees.

Important ! If minor distortions in the roof are detected, they can be corrected when installing the sheathing or using additional elements if the unevenness is located at the ends.

Installation of sheathing

Used for lathing edged boards, pre-treated with an antiseptic. Recommended dimensions – 100x25 mm. Installation is carried out from the eaves overhang in compliance with the mandatory rules:

1. The first board is placed immediately along the eaves overhang, strictly horizontally. Its thickness should be 10-15 mm greater than that of other boards. This difference will allow you to compensate for the height of the support points of the first and then subsequent modules.
2. The second beam is attached at a distance of 250-300 mm.
3. Subsequent boards are arranged in larger increments - 350-400 mm.
4. Every five rows, control measurements are taken of the distance between the sheathing beams.

Important ! Control measurements should be carried out starting from the very first board, since any mistake with the horizontal components of the battens will lead to the fact that the entire work will have to be redone.

Correct installation of sheathing is the key to successful roof covering with metal tiles

The installation of the sheathing ends with strengthening the ridge and end strips. At the same time, to attach the ridge, you should take care of additional boards measuring 100x25 mm. For the ridge board, take more thick timber– by 10-15 mm. This will help create the necessary ventilation gap when installing the roofing material.

And the wind strip is attached in such a way that it is located above the sheathing to the height of the metal tile sheet.

Important ! If the design takes into account drainage from the roof, then the installation of brackets must be carried out when installing the sheathing.

Roof waterproofing

Laying the waterproofing layer must be carried out before installing the sheathing. The task of waterproofing is to allow condensation from the insulation layer to evaporate, but at the same time prevent the penetration of moisture from the outside.

When figuring out how to cover a roof with metal tiles, you should pay a lot of attention to the compatibility of materials. For example, it is recommended to use a membrane as waterproofing. Its installation must be carried out across the slope, and the joint of the film must be overlapped, with an overlap of 100 mm.

The film is fastened along the counter-lattice for better ventilation between the film itself and the metal tile.

Waterproofing is carried out before installation of the sheathing.

Steam and heat insulation

To insulate the under-roof space, it is mandatory to use vapor barrier films and insulation, providing a comfortable microclimate in the house.

Vapor barrier is necessary so that the insulation is not exposed to water vapor from the premises. Providing protection thermal insulation characteristics, film becomes a mandatory attribute warm roof.

Installation of roofing layers is carried out in accordance with the requirements for the materials used. A prerequisite is the tight joining of films with the creation of additional insulating layers.

Important ! When laying metal tiles on cold roof There is no need to install heat and vapor barriers.

Cutting and installation of sheets

Sheets of metal tiles can be cut both on the ground and on the roof itself. Installation can be carried out in any direction, the main thing is to follow the technique, rules for laying and fastening roofing material.

The installation technology requires you to adhere to a number of simple instructions:

To fasten sheets of metal tiles, self-tapping screws are used that match the color of the roofing material. Each element is installed together with a gasket, the purpose of which is to minimize corrosion damage. The size of the screws is 4.8x28 mm. They are screwed into the sheets strictly perpendicularly so that the gasket underneath them is slightly compressed.

Important ! The chips formed when installing self-tapping screws should be removed with a soft brush.

After tightening the screw, the strip underneath should be slightly compressed

Each house has unique architectural features. To take into account all the nuances during installation, it is recommended to use not only textual information. The most useful, necessary and visual material how to cover a roof with metal tiles - video. Its viewing is required for everyone who is not involved in roofing work professionally.

Conclusion

Metal tiles are beautiful and durable material, great for almost any home. The apparent ease of installation simply beckons you to do the work yourself. But, as when working with everyone building materials, here it is worth considering a lot of significant and not so significant points.

Only those craftsmen who constantly work in the field of roofing installation can know all the features. By entrusting the work to professionals, you can relax knowing that everything will be done correctly. the highest level, which means the house will be cozy and comfortable.

Working with metal tiles when laying the roof will be much easier and simpler if you understand the installation features and strictly follow the basic construction rules and recommendations from the manufacturers of this material.

Use of roofing material

Characteristics of metal tiles as a roofing material

Metal tiles are an inexpensive, but quite practical and economical roofing material with a metal base covered only with a zinc coating on both sides, or with the addition of a synthetic coating on the front side.

The main advantages of metal tiles are:

The anti-corrosion function is provided by a zinc coating on a metal base. Spray level roofing sheet zinc can vary from 140 to 275 g/sq.m. m, which is determined by the manufacturer based on climatic conditions where potential consumers live.

Manufacturers managed to achieve weight reduction through the use of thin steel sheets. Although minimum thickness material 0.4 mm, experts recommend using sheets of 0.5 mm or more for installation to avoid deformation of the roofing components.

This property should be given Special attention, since, for example, with increasing thickness composite metal tiles the installation will successfully withstand, and the roof will become much stronger, but this will affect the load of the structure in relation to rafter system and the foundation of the building. The maximum sheet thickness is 1 mm.

Metal tiles are offered on the market in 26 different color options, which will allow you to approach the construction of the roof creatively. In addition to the external attractiveness of the material, this solution provides a kind of protection of the material from exposure ultraviolet radiation, chemical substances and mechanical damage.

Sequence of installation of metal tiles

1. A waterproofing layer is laid. It will help prevent condensation from forming on metal sheet due to temperature fluctuations outside and exposure warm air penetrating from the interior.
2. Roof insulation. Thermal insulation material fixed between rafter legs, which will improve sound insulation and retain heat inside the house or cottage.
3. Vapor barrier. For correct installation vapor barrier, a special film is attached to the rafters with inside taking into account the overlap, the amount of which, as a rule, is already indicated by the manufacturer in the form of a corresponding mark on the film itself. The overlap of two sheets of material is sealed using construction adhesive tape.
4. Creating a sheathing. For work you will need wooden beams 50x50 mm, which are fastened at intervals of 300-400 mm - depending on the design features and the chosen type of metal tile. We draw the attention of those who did not know before how to install metal tiles correctly to maintain the distance between the sheathing bars: the greater the weight of the material, the smaller the gap.

For example, if the thickness of the lathing is 50 mm, then the distance is 300 mm, and with bars of 80 mm, the gap should be 270 mm.

Several falling beams are nailed to the rafters on top of the waterproofing from top to bottom - from the ridge to the eaves, then wooden battens of the sheathing. Compliance with the listed requirements will allow you to avoid deformation of the roofing covering and maintain its quality during further exploitation. The first board should be 10-15 mm longer than the others, as shown in the photo.

Laying metal tiles

Initially, you should check the structure for distortions and other defects in the roof, due to which the quality of the connection when assembling the sheets will be greatly reduced.

To create ventilation attic space A special strip with a triangular seal is attached to the cornice - its joints serve as a source of air flow into the under-roof space. After this, the valley is installed when roofing with metal tiles from V-shaped parts of the internal valley joint.

Raising galvanized sheets is quite simple; to do this, two bars must be placed at a slight angle. It is better to transport the material together: one feeds the sheet from below, the second pulls it to the roof. When performing this, remember to follow safety precautions.

Experts point out that due to the sharp edges, tiles moving at high speed can cut anything that gets under them.

Fasteners must be made according to the basic rule - self-tapping screws are screwed only into drilled holes and with a special rubber washer.

Do not under any circumstances overtighten the screws, but even if the fastening is weak, the installation will be performed incorrectly. Both cases are fraught with the formation of cracks and leakage of the roof.

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 desired, you can order tiles by custom sizes, but it 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;
• facilities personal protection(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 lathing made 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 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 in this case starts from the bottom and overlaps 25-30 cm. Below the level of the cornice, the bottom strip is cut, 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. Wherein eaves overhang 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 are 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. 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 polymer layer which 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.
