After the rafter system is already ready, the question arises - how to properly lay the metal tile? To begin with, it is necessary to carry out control measurements of the slopes, since minor deviations could occur during the construction of the house and the rafter system. Such a check is performed on the rectangularity and flatness of the roof, measuring the length of the diagonals of the slopes. Minor rectangular defects can be hidden by additional elements (read: ""). Otherwise, it will be necessary to trim the slopes.
The main dimension that determines the length of the sheet is the height of the slope (from the eaves). This takes into account the overhang of the metal tile from the eaves (approximately 3-4 cm). If the length of the slope is more than 7 meters, then it is customary to divide the sheets into several pieces, which are laid with an overlap of 15 cm. The use of long sheets allows you to organize fewer joints. But working with such sheets is a little more difficult than with short ones. Well, it depends on the specific model of the material.
Daily temperature fluctuations lead to the formation of condensation on the inner surface of the metal tile. In addition, steam is converted into water, which rises from the interior of the house. An excess of moisture becomes the reason for the soaking of the insulation and the loss of its thermal properties. Also, high humidity is the main reason for the freezing of the roof, the formation of ice, the appearance of mold and rotting of the wooden elements of the roof.
To remove moisture from the under-roof space, natural ventilation is organized so that air can easily pass from the eaves to the ridge. Therefore, a ventilation gap with a height of 4-5 cm is left between the metal tile and the waterproofing. In the filing of the eaves of the roof, ventilation slots with a width of 5 cm are also provided.
Waterproofing device
A special membrane-type film acts as a waterproofing. Its principle of operation lies in the fact that moisture from the side of the roofing cannot penetrate to the insulation, at the same time warm air from the internal premises freely flows through the membranes into the ventilation gap.
Attaching additional elements
If the gutter system is created from rectangular profiles, then the gutter is inserted into the holders. Then a cornice-type bar is attached to the crate underneath. In this case, its lower edge should overlap the edge of the gutter. The under-roof waterproofing is brought out over the eaves strip. This is done so that the condensate can drain freely into the gutter.
If a circular profile is used to organize the drainage system, then the gutter is inserted into the holders, while its edge is inserted into the fixing protrusion. The eaves-type plank is attached so that its lower edge overlaps the edge of the gutter. Roof waterproofing is removed in the same way as in the previous case.
End strips are attached to the ends of the roof. They are installed in 50-60 cm increments using self-tapping screws. An overlap of 50 mm should form between the planks. If necessary, the end strips are trimmed.
Then the ridge strips are installed. They are of two types: flat and round. For a strip of circular cross-section, the installation begins with fastening flat or conical plugs at its ends (for this, rivets or self-tapping screws are used). In the case of a flat ridge strip, such plugs are not needed.
In addition, a seal is placed on the ridge. It is on it that the ridge strip will be installed. In this case, it is necessary to first cut out the places for the ventilation holes in the seal. The ridge strip is fixed using roofing screws 80 mm long. They are screwed in at every second wave of the shingles. An overlap of 10 cm is organized between the ridge strips.
How to install metal tiles - roofing
In order to ensure the safety of movement on the roof during maintenance work, a vertical fence is attached to the cornice. The crate for the fence is made, as for other accessories - solid. The fence supports are fixed with galvanized screws in the places of deflection of the waves of the tile. The support is installed taking into account the level of the roof slope. The step between two adjacent supports is often 90 cm. After the supports are fixed, a fence is attached to them.

Laying the roof on the roof and installing the drainage system is the final stage in the construction of the house box, depending on weather conditions. All further work on the arrangement of the interior can be performed at any time of the year and in any weather, which greatly simplifies and speeds up the construction process. Roofing works are carried out at high heights, this creates additional difficulties and requires unconditional adherence to safety rules.
Roof overlapping is carried out in the most difficult conditions and requires the utmost care and attention. The roof is one of the most critical elements of any building or structure. That is why experienced builders should not only theoretically know all the intricacies of the work, but also have solid practical experience, to put metal tiles on the roof.
The fact is that life is much more complicated than any book, none of them can foresee all situations that arise during roofing work. This article will give practical advice and consider detailed step-by-step instructions, the knowledge gained will help you make the right decisions on your own to solve various problems.
It is dangerous to work at height, it is highly undesirable to be distracted by faulty tools. Before starting work, you need to check their technical condition, replace cutting elements, etc. Professionals strongly advise buying a special carpenter's belt. It has many different pockets and fixtures for fixing hand tools and hardware, they are always at hand, attention is not distracted by searches, time is not wasted in vain.
Coating technology requires the preparation of the following tools:
Important. It is highly recommended to purchase a spray can with the same paint at the same time as buying metal tiles. It is necessary to paint over the cut points, scratches on the surface of the sheets and other minor mechanical damage to the roof.

Preparatory activities
In order to prevent unforeseen situations during the execution of work, the process is not slowed down and the quality of the roof does not decrease, all your actions need to be thought out and divided into several stages.
The first stage is the delivery of materials
It is necessary to measure the dimensions of the roof slopes, calculate the number and length of valleys and ridge, draw a drainage diagram. Based on these data, store employees using a special program will calculate the optimal amount of each element, hardware and calculate the amount. It is not necessary to immediately order the material, you can make such calculations in several trade outlets and, based on the information available, choose the most suitable option for yourself. You should immediately agree on the delivery of the roof, the length of the car body must be at least the length of the sheets of metal tiles.
Practical advice. If such a car is expensive or difficult to find, then long boards can be nailed to the short body. The roof can be transported over short distances on such adapted vehicles.
Immediately select a site for storing materials, level its surface, and, if necessary, make a temporary shed.
The second stage is the manufacture of devices
You must have at least three devices, they significantly speed up the process of installing metal tiles and increase labor safety.
| Device name | Purpose and short description |
|---|---|
| It is used during the installation of eaves and drainage systems. In the upper part it has two special legs that rest against the wall of the house. Due to this design, the likelihood of damage to the overhang of the tiles is excluded, the gutter does not bend. The ladder is lightweight, it can be easily transferred to a new place as required by the technology. |
| They not only make installation work much easier, but also make them safe. On two-story houses, scaffolding must be installed and have special handrails for stopping. They can be home-made or factory-made, there are a large number of options for making scaffolding, the specific one should be chosen taking into account individual conditions. |
| Externally it looks like a wooden staircase, in the upper part there are special hooks for fixing it to the roof ridge. Allows you to move around the installed roof and not damage it. It greatly facilitates the process of screwing in self-tapping screws, bypassing chimneys, sealing joints. This attachment is considered mandatory for safety reasons. |
| The simplest device. It is enough to fasten together two parallel boards of the required length. The device is used to feed sheets of metal tiles to the roof of the house. |
You need to work in shoes with soft and non-slip soles, clothes should be loose, do not interfere with movements, without hanging parts.
The third stage is checking the dimensions of the rafter system
It is not too late to fix the problems of the rafter system. First, make sure that the slopes of the gable roof are rectangular. This is done simply, you need to measure two diagonals, if they are the same - everything is normal. If there is a difference, then you need to eliminate the marriage. Triangular slopes should be in the form of isosceles triangles, check the location of the vertex, its projection should be located exactly in the middle.
At the same time, you need to measure the distance between the battens of the crate. These parameters depend on the type of metal tiles.
Fourth stage - roofing works
You should only start with careful preparation. It is necessary to inquire about the weather forecast and choose sunny days. This is especially important if you plan to make a warm roof. Mineral wool gets wet quickly and dries for a very long time. If trouble happened with the insulation already laid between the rafters, then it will have to be removed. This is not only long, but can also cause mechanical damage to the insulation.
Metal roofing is the most popular in the construction of private and multi-storey buildings, public and industrial buildings, the creation of small architectural forms. A thin profile sheet imitates ceramic tile masonry, but at the same time is devoid of its drawbacks - significant weight, complex installation and high price. The coating is used for pitched roofs with an inclination angle of more than 12 °.
The first metal tile was produced in the early 80s in Finland. She quickly gained recognition from architects, designers and builders. The end consumer also appreciated the novelty. In Russia, roofing material appeared in the 90s. Now it is used in regions with different climates - in the harsh northern latitudes and in the hot south. Earlier we wrote about how to do it with our own hands without the help of specialists, in any case it will be useful for you to read, even if specialists will work.
The basis of the metal tile is a cold-formed profile sheet made of steel, aluminum or copper, coated with zinc-containing compounds, a base, a primer and polymer materials. The thin outer layer also has a decorative function. Surfaces have different textures and colors.
Metal tile device schematically.
Types of protective and decorative external coatings
Coating table by temperature.
Roofing sheets are coated with polymers that are resistant to temperature extremes and solar radiation. The film applied to the outer side of the product must be flexible, durable, and reliably protect steel from corrosion. These requirements are met:
Manufacturers for the needs of the consumer produce metal tiles with coatings of various compositions and characteristics. The polymers are sandwiched with quartz sand, spot-stamped on the surface, and aluminum and zinc are added to the base. Some films have soundproofing properties, which is important for metal roofs. For high-quality products, the warranty period reaches 70 years.
What kind of profile are there
Metal roofing is made from rolled products with a thickness of 0.4-0.5 mm. The sheet is shaped using the cold pressure method. First, a longitudinal wave is formed, then a transverse relief. The products acquire a finished look, imitating a variety of clay plate masonry. The consumer will be able to choose the most suitable option for home decoration.
Calculation table of the sizes of metal tile profiles.
Monterrey... The classic form of roof tiles in the Finnish tradition. Rounded edges, low wave, smooth curves are the distinctive features of the geometry of this profile. Varieties - SuperMonterrey, Maxi.
Cascade. The profile resembles rectangular plates floating on top of each other. The waves are clearly defined, the edges are straight and strict. It fits comfortably with valleys or gutters, therefore it is used for the construction of complex roofs. Variety - MaxiCascade with an extended wave.
Spanish dune... Sheet material is produced in Russia in the Moscow region. The width of the element is 540 mm, along the longitudinal edges there are a groove and a hook for hidden fastening. Self-tapping screws screwed into the mounting holes are overlapped from above by an adjacent part. Water, not getting into the joints or under the fasteners, does not cause corrosion. Metal tiles are made to fit the size of the slope. Variety - Andalusia.
Finner... Finnish modular roofing material 705x1190 mm. The two-wave element has a fold-over at the leading edge for additional weather protection.
Adamante... Matt PURAL coated metal tiles imitate Mediterranean clay roofs. Profile with a soft wave, very rich colors. Variety - Country with a polymer layer of polyester.
Novelties of profiles of Finnish and Russian manufacturers - Dekkorei with a ridge height of 18 mm, Banga with a round convex wave, Shanghai with alternating protrusions of different sizes.
Metal roofing: waterproofing and vapor barrier
Metal roofing is arranged according to two technologies - warm or cold. The choice of option depends on the purpose of the attic space. For living quarters, slopes and gables are insulated, if it is unheated, thermal insulation is laid along the ceiling. Installation of a roofing cake in each case has its own characteristics.
Warm roof
The device of a warm metal roofing begins with the installation of waterproofing. It protects the insulation and the wooden roof structure from condensation and accidentally leaked water. At the same time, it acts as a windbreak - they prevent the blowing of the heat insulator fibers through the cracks.
Waterproofing is laid on top of the rafters. To do this, apply:
- inexpensive polyethylene or propylene films that do not allow steam to pass through;
- diffuse breathable membranes.
If polyethylene films are used, then a ventilation gap is arranged between them and the insulation. This will allow moisture to evaporate.
The film or membrane is mounted with a stapler to the rafters without sagging. At the joints, the panels are fastened with an overlap of 15 cm wide. They are glued with tape to avoid blowing out the wind. Laying direction - from bottom to top for free flow of water over the waterproofing surface.
When laying the membranes, orient them according to the instructions. Since the passage of vapors is foreseen in one direction, care must be taken. Otherwise, the result will be the opposite. Usually the manufacturer prints a logo or a bright stripe on the outside.
On top of the waterproofing, counter-lattice bars with a thickness of 40-50 mm are mounted. This provides the necessary ventilation gap between the film and the metal tile.
Basalt wool mats are placed between the rafters. On the underside, the thermal insulation is protected with vapor-proof films. If this is not done, condensation will form in the thickness of the material. This degrades the properties of the insulation, creates a source of constant dampness in the premises.
Vapor barrier is made of films, membranes, reflective foil materials with vapor permeability in the range of 0-90 g / m2 * day. They are attached to the rafters from the inside, trying to maintain the tightness of the coating. To do this, the joints are carefully glued, the places where the communications pass are duplicated with overlays with cut holes.
Important. Foil films are laid, turning the metal layer inside the room. Heat waves are reflected from the barrier without being emitted into the atmosphere. For gluing, choose an adhesive tape with a metallized layer.
Cold roof
In cold roofs, the insulation is laid on the ceiling of the upper floor. At the same time, it is also protected from moisture penetration by insulating materials.
Only a waterproofing layer is placed under the metal tile. It protects the under-roof space and the rafter system from condensation formed on the inner surface of the profile sheet.
Films or membranes are used for waterproofing. Their choice is quite large. The materials are fastened in the same way as the insulated version. A small - 20 mm - sag is left between the rafters for condensation to drain into the drainage system. All joints are sealed with adhesive tape.
To reduce the noise generated by rain or hail, waterproofing is combined with soundproofing. Dense heavy membranes, barriers based on acoustic felt or rubber, penofol, mineral wool are used.
Fastening and laying metal tiles - step by step
Installation of metal roofing is performed, as a rule, by professional teams. The weight of a square meter of roofing material is 4-7 kg, which makes it easy to lift the sheets and install them on the roof. With construction skills and a set of tools, you can do this with an assistant.
For work you will need:
- ladder and stepladder;
- cutting tool - scissors for metal, a hacksaw with a fine tooth, an electric jigsaw, a circular saw;
- screwdriver;
- hammer;
- roulette;
- long rail;
- marker or pencil for marking;
- soft brush for removing sawdust after cutting.
Important. It is not recommended to cut metal tiles with a manual grinder. Rotating at high speed, the abrasive wheel burns out the protective zinc and polymer coating. This accelerates the formation of corrosion, leading to the appearance of rust.
The sheets are attached to the crate with colored galvanized self-tapping screws with an EPDM rubber gasket, screwing them in with a screwdriver.
If scratches appear during installation, they are painted over with an aerosol of the same color as the base material. Wooden elements are treated with an antiseptic.
Stages of work when laying metal tiles:
- Check the geometry of the roof with a tape measure. The diagonals of the ramp must be equal.
- Hydro-, steam- and thermal insulation is installed according to the project.
- A counter-lattice is installed along the rafters of 40x50 or 50x50 mm bars.
- The lathing of boards 40-50 mm thick is nailed parallel to the ridge with a step equal to the wavelength of the metal tile. For the most common Monterrey profile, this is 350 mm.
- Hooks for the drainage system, cornice strips and a gutter are fixed on the lower element of the lathing. It should be 25-30 mm below the edge of the roof.
- In the places of inclined joints of the slopes, the elements of the lower valleys are overlapped.
- Sheets of metal tiles are mounted from right to left. Each previous sheet is overlapped by the next one by one wave. Fastened with self-tapping screws.
- The joints are closed with upper valleys.
- Install end strips with seals.
- Snow holders are mounted at a distance of 350 mm from the cornice.
Self-tapping screws are screwed into the center of the wave deflection 3-5 cm below the stamp relief. The fasteners are placed strictly perpendicularly. The rubber washer should fit snugly against the surface of the sheet. Incorrect installation will result in gaps or deformation of the elastic pad.
Important.You cannot fix self-tapping screws in the upper part of the wave, this will lead to a fragile fixation of the profile. It is unacceptable to use boards of different thicknesses for the frame, to install them with an uneven pitch. The result is coating defects.
Installation of metal tiles - step by step instructions
Before starting work, a preliminary calculation is carried out to determine the consumption of materials. The upper edges of the profiles are asymmetrical, therefore, they cannot be reversed when laying out. In addition to the basic dimensions of the element, its working dimensions are taken into account, taking into account the overlap.
In the drawing, the position of each sheet is marked. In gable roofs, installation begins from the lower right or left corner of the slope. The second element is placed side by side. The third panel is fixed above the first, the fourth - above the second.
For hipped roofs or more complex roofs, the starting line is the vertical where the highest point is. Laying begins with the device of joints or abutments.
To regulate the position of the sheets, they are first temporarily fixed to each other, without screwing them to the crate, 2-3 pieces in a row. Then the formed block is leveled and firmly fixed.
Important. They walk on metal tiles only in soft shoes, trying to step into the deflections of the wave.
Installation of additional elements
Additional elements are intended for sealing joints, joints and abutments of the roof, giving it a complete look. For each type and color of tiles, the corresponding profiles are produced. They are made from the same steel sheet with a protective coating.
To decorate roofs use:
- Cornice planks - drip pieces installed along the bottom of the cornice. They are used to collect condensate from the under-roof space, to protect from rain in case of a crosswind. The elements are fixed with self-tapping screws to the bottom board of the crate, which should be 10-15 mm thicker than the rest. Roof overhangs are hemmed with soffits or profiles.
- End strips - Protect the roof gable from wind gusts. They are also called wind or pediment. The upper part is attached to the metal tile, the lower one to the wind board.
- Ridge strip - a profile for decorating the top of the roof of a round, triangular, trapezoidal or rectangular shape. For a snug fit to the curly tiles, the padding is sealed with foam rubber. It is breathable, but creates a barrier to birds or insects. The strips are completed with plugs that repeat the shape of the end hole. Along the length, they are joined with an overlap or a lock fastening.
- Endovy - curly strips designed to remove atmospheric moisture flowing from the roof surface, and to decorate the joint from above.
Sealing of joints, locations of roof windows or communications is performed with strips, wall profiles, external abutments and passages. To protect against the descent of large layers of snow, corner, tubular or lattice snow holders are installed on the slopes.
Important. Fastening elements must be fixed in such a way as to eliminate the risk of leaks. For this, seals, steel clips, sealants are used.
Output
A roof made of metal tiles is a worthy alternative to natural tiles. Available in a variety of profiles. The service life of materials with high-quality coating reaches 70 years. An important condition is correct installation and operation.
Metal tiles are a reliable and durable roof covering. High corrosion resistance of this material is ensured through the use of high quality raw materials (galvanized steel from the world's leading manufacturers) and special polymer coatings. In the Stroymet company you can buy. We also stock roofing materials from other well-known manufacturers from Russia and Finland.

Basic requirements when working with metal tiles
Shipping
To avoid damage, the sheets must be fixed in the car body. At the same time, they must completely fit in the body along the length (otherwise, bends are possible on the overhang line). The optimal mode of movement of the vehicle: the speed is not higher than 80 km / h, without sudden acceleration and deceleration.
Loading and unloading works
They can be made manually or using special equipment (forklift trucks, cranes with soft slings). The packages are unloaded onto a flat, clean, dry surface. The number of personnel for manual unloading depends on the length of the sheets (1 person per 2 running meters, but not less than 2 people per 1 sheet). Carrying is carried out in an upright position. It is forbidden to drag sheets along the ground and other surfaces.
Sheets of metal tiles are stacked using wooden blocks (stacked at the base of the stacks) and slats (stacked between the sheets). If storage is carried out in an open area, it is necessary to provide a slight slope of the sheets along the length for water drainage. In the immediate vicinity of the storage place, it is prohibited to carry out welding work, as well as other operations that can damage the surface of the metal tile.
Safety engineering
In order to avoid cuts on sharp edges of metal tiles, personnel must work in protective gloves. In the process of lifting sheets to the roof and installing them, it is necessary to use safety equipment. It is forbidden to carry out high-altitude work in difficult weather conditions (with strong wind, rain, hail, snowfall).
Fasteners
To fix the sheets of metal tiles, self-tapping screws made of stainless steel with a polymer gasket are used. Approximate consumption - 6-7 screws per 1 sq. m.

Note! When cutting metal tiles, do not use angle grinders with abrasive wheels. Violation of this requirement can lead to intensive corrosion of products (due to damage to the zinc layer and polymer coating).
Roofing cake structure
Modern roofs are made up of several layers with different functions. The reliability and durability of the roof is ensured through the use of high-quality materials and the correct installation of the Grand Line metal tile. If even one element is incorrectly installed, this will lead to a sharp decrease in the service life of the entire structure. According to the experience of Stroymet specialists, a violation of the requirements for laying leads to the accumulation of moisture in the insulation (because of this, its operational characteristics are significantly deteriorated), as well as the destruction of wooden and metal parts (due to decay and corrosion).
- Metal tiles.
- Lathing.
- Waterproofing.
- Rafter leg.
- Counter grill.
- Vapor barrier membrane.
- The first lathing board.
- Gutter bracket.
- Frontal board.
- Dropper.
- Cornice strip.
- Perforated ventilation tape.
Installation of thermal insulation
Fits between the elements of the rafter system. To keep it better, it needs to be cut with a small margin in width (1-1.5 cm). Installation should be organized in such a way as to completely exclude the possibility of moisture ingress into the thermal insulation layer.
Installation of vapor-waterproofing films and membranes
Insulation materials are laid on both sides of the rafter structure: outside - waterproofing, inside - vapor barrier. Laying is done horizontally, from bottom to top, with an overlap of 15-20 cm.
Standard waterproofing is installed with 2 ventilation gaps of 3-5 cm:
- between the film and the heat-insulating layer;
- between the film and the roof covering.
The Super Diffusion Membrane is installed with 1 gap (between the membrane and the roof covering). A second gap is not needed because the performance of the membrane allows it to be laid directly on top of the thermal insulation layer.
When installing a vapor barrier, a gap is required between the film and the inner lining. The overlap lines of adjacent film rows are sealed with a sealing tape.
Installation of gutter brackets
Brackets designed to fix the gutter are mounted in such a way as to ensure a slight slope of the structure towards the downpipes. The parameters of the vertical displacement are determined by the formula: h = 0.005 x L (L is the distance between the extreme hooks). Brackets are pre-numbered and marked taking into account the specified offset. Correct installation of long brackets is only possible prior to laying the roof covering. The design of the short brackets allows them to be fixed to the frontal board at any stage of roofing work.
Installation of the lathing
The lathing is usually made from wooden planks and bars. They must first be dried and treated with fire and bioprotective compounds.
In the lower part of the eaves overhang, a drip is mounted, designed to drain water and condensate into the gutter.
The first board of the sheathing should be thicker than the rest (the wave height of the metal tile is added to the standard thickness). The recommended distance between the bottom edge of the first board and the middle of the second is 30 cm, from the center to the center of the remaining elements of the sheathing is 35 cm.
Next to the ridge, in the valley area, in the places where the snow holders are installed, along the perimeter of the chimneys, a solid crate is mounted.
Installation of eaves planks
The eaves strip protects the frontal board from moisture and dirt. With the help of self-tapping screws, a ventilation tape is attached to the ends of the counter-rails and the first board of the crate.
Installation of the lower valley planks
The joints of adjacent slopes are subject to increased operational loads. Therefore, a continuous crate is installed in the valley area and a special seal is mounted. The valley planks are mounted from the bottom up (starting from the eaves plank) with an overlap of 30 cm.
Installation of a bypass around the perimeter of the chimney
The waterproofing film is brought to the surface of the pipe (overlap of at least 5 cm) and fixed with self-adhesive tape. Then, abutment strips are mounted around the perimeter, which are inserted with the upper side into the grooves made in the outer wall of the pipe (the recommended depth is 1.5 cm). After that, a drainage is made (to the nearest plank of the valley or to the eaves overhang).
Before the installation of the Grand Line metal tile, a lifting structure is mounted from wooden boards and bars, on which the sheets are fixed. After that, the metal tile, together with the structure, gently rises to the roof. Personnel must use safety equipment during the ascent.
Installation of metal tiles Grand Line
In order to avoid damage to the sheets, work must be carried out in shoes with soft soles (sports or special), while you can only step into the deflection of the wave.
Laying is done from bottom to top. The lower edge of the sheets is carried out 5 cm behind the cornice and is carefully leveled along the entire length of the slope.
Before starting the installation of the Grand Line metal tile, it is recommended to install a lightning rod.
- The sheets are attached to the deflections of the waves in places of tight fit to the sheathing boards.
- The metal tile is attached to the first board of the sheathing through the wave, above the step.
- To other boards, sheets are attached under the steps (as close as possible to them).
- Along the edges of the slopes (at the gables), each step is fixed with self-tapping screws.
Pass-through roof exits
To ensure the tightness of through exits, Stroymet specialists recommend using self-adhesive tape and silicone sealant.
Dormer windows
Installation is carried out in the following order:
- the lower plank of the valley (carried out below the line of the gable of the dormer construction);
- roof covering;
- the upper plate of the valley (it is recommended to install a special seal before installation).
Installation of end plates
The strips are mounted from the bottom up with an overlap of 10 cm (the recommended pitch between the screws is 30-35 cm).
Installation of the upper valley plank
Carried out after laying the universal seal. It allows you to hide possible unevenness of the trimmed sheets at the junction of adjacent slopes.
Installation of abutment strips
In the places where the metal tile adjoins the vertical elements, a polymer seal must be installed to ensure effective waterproofing. The planks are fixed with roofing screws.
Ridge installation
The ridge bar is fixed through the wave with special ridge self-tapping screws (they are longer than standard ones). A self-adhesive ventilation tape is pre-mounted along the entire ridge. Caps are installed at the ends of the ridge.
Installation of roof safety elements
In the areas where snow guards, roof ladders, walkways, fences will be installed, a solid crate must be installed.
Snow guards are installed in the lower part of the ramp (but above the eaves overhang, otherwise they may not cope with the snow load).
Fasteners must fall not only into the crate, but also into the elements of the rafter system.
Eaves filing
Plastic or corrugated board can be used as materials for cladding.
At the same time, it is necessary to ensure a good level of ventilation of the under-roof space (for this, Vilpe valves are usually used).
According to the specialists of the Stroymet company, the optimal solution for filing eaves is vinyl soffits. Their installation is carried out using wooden beams and additional elements (J-profile and J-bevel). Perforated soffits help maintain a comfortable air circulation in the under-roof space.
Installation options for gutter brackets
The dropper is used to drain condensate from the waterproofing film (connected to it with double-sided tape).
Ventilation tape - prevents clogging of the under-roof space, improves air exchange. Fixed with self-tapping screws.
Post-installation care
At the end of the installation of the Grand Line metal tile, all debris (metal scraps, shavings, remains of consumables, etc.) must be removed from the roof surface. If micro-scratches are found on the sheets of the Grand Line metal tile, it is recommended to apply a special paint to them. This will not only make damage invisible, but also prevent corrosion.
The procedure for installing gutters
- The gutter is marked for the installation of funnels.
- Holes of the required size are cut out, funnels are installed.
- Plugs are attached to the ends of the gutter (rivets and silicone sealant can be used for additional waterproofing).
- The gutters are installed on brackets and connected to each other using special connectors.
- The brackets for fixing the drainpipes are installed on the building facade with a step of 1 m (at least 2 brackets for 1 pipe).
- Installation of a downpipe (pipes, elbows, connecting pipes) is in progress. The drain knee should be located 20 cm from the ground.
- The downpipe is connected to the funnel, then the structure is adjusted and all the brackets and clamps of the riser are fixed.
Primorskaya zone (less than 3 km from the sea shore)
You can familiarize yourself with the conditions for granting a corporate guarantee for the Grand Line metal tile when purchasing at the sales offices of the Stroymet company (detailed information is contained in the warranty coupons).
