Apparatus roof of metal: coating characteristics

Metal is a cladding material consisting of galvanized sheet steel. Coating manufactured in the form of profiled metal sheets with a specific external appearance imitating natural tile structure.

The circuit construction and roofing of metal

The circuit construction and roofing of metal

Profiling is done by imparting a trapezoidal or undulating form sheets, thus enhancing performance of the material.

Metal has a number of advantages, among which are the low weight material, so it does not create a significant additional load on the load-bearing structures structure. This coating is characterized by high wear resistance, high strength, resistance to mechanical impact and shock loads, fire resistance, long life, is 15-25 years old, simple installation and a good potential for the realization of interesting design solutions.

However, the metal is not without drawbacks. They can be avoided by observing the rules of planning and installation work. Coating metal tile has a low sound insulation. With strong gusts of wind and precipitation create increased noise. This can be avoided, to equip a good sound insulation, - to this end applied a layer of heat insulating material.

In the interior space of the roof can collect condensate. To exclude such an adverse factor should properly think through the vapor barrier and the roof ventilation system. Metal has another disadvantage that due to material during overrun device roof. Roof covering discharged fixed dimensions, because of which inevitably the formation of extra lengths of material. Especially such overruns noticeable when the roof assembly of complex shape with multiple bends and corners.

The composition, structure and coating of metal species on the roof

Metal, which graphically represent the structure of photo products, represented as the steel sheet thickness 0,45-0,6 mm. It is coated on both sides with a protective layer of zinc or other special alloy. On the inner and outer surface of the article is applied preservative coating which consists of passivation, primer and decorative layers. The latter is a colored polymeric coating, which gives the product a certain color. To produce a profile sheet using aluminum, steel, copper, and zinc alloys.

Important!Copper metal has high strength, wear resistance and durability.

Variant decorative coating determines the texture, color, resistance to discoloration, resistance to mechanical damage and corrosion products. The resin composition used glossy and matt polyester, polyurethane coating, PVDF, plastisol.

Polyester Gloss is low, but effective coating thickness of 30 microns. The material is characterized by high corrosion rates, resistance to the adverse effects of solar radiation. Life of the product is not more than 15 years.

Metal has several different layers of the coating on both sides

Metal has several different layers of the coating on both sides

The layer thickness of the matt polyester is 35-50 microns. The material is resistant to fading and mechanical effects, which perceives roof. Metal will last about 15-20 years. A coating of polyurethane polymer having a thickness of 50 microns. Roof with such metal tile may be used for buildings, located in different latitudes, since the coating can withstand a range of temperatures from -60 ° C to +100 ° C. Such material has a high degree of resistance to UV and corrosion resistance. The service life of 35-40 years.

PVDF thin polymer coating thickness up to 30 micrometers characterized by high resistance to mechanical and chemical influences. Subject to all rules of installation technologies such metal roofing is able to last up to 40 years.

Prostizol coating is formed on the basis of polyvinyl chloride, a thickness of 2 mm. Characterized by high corrosion resistance and durability, which is 50 years. The fine structure of the embossed pattern surface coating imparts an attractive appearance, as seen in the photo of metal roofs.

Metal species, their characteristics

Metal has several varieties, depending on the profile of the product and form of cutting.

Modular stamped sheet metal is made up to 1 m and a width of 1.2 m

Modular stamped sheet metal is made up to 1 m and a width of 1.2 m

The profile defines the shape of used stamping products. Depending on this, there is a metal roof (photo clearly show the different profiles), Andalusia, Monterrey, Cascade, Modern, Banga, Dekkorey, Elite, Finnair, Classic, Vintage.

Andalusia is a wave profile having a mirror-symmetrical descents and ascents. Monterrey - a symmetrical corrugated profile, which has a wave slope is steeper and shorter than the rise. Cascade - undulated profile having a sectional shape of a trapezoid. It is made from galvanized steel coated polyester. Profile resembles a chocolate bar as shown in the photo of the roof. Modern Metal represented asymmetrical profile waves, which is in the form of flat faces.

Banga product has a high wave reaching 660 mm. Option Dekkorey - the low profile, so that the product acquires a refined appearance. Elite Tile different from the other versions of the largest wave height that best looks on the roof with large slopes.

Profile Finnair is a new waveform, resulting in appearance is similar to the cement-sand or ceramic tiles. Profiles Classic Vintage and have smooth coating with small sides, through which articles are joined together to form a seamless surface.

Metal may be different types of external, that depends on the profile of the product and form cutting

Metal may be different types of external, that depends on the profile of the product and form cutting

Form cutting of the material (it determines the ease of installation of metal with their hands) can be a sheet, a modular or boxed. The first option is the most popular and the least expensive, is represented blade length of 0.5-8 m and a width of 1.18 m. Used for large area or uni-pitched roofs. Price per m2 of metal installation starts from 180 rubles.

Modular tile stamped sheets presented short length of 1 m and a width of 1.2 m. The piece variant looks as separate elements that are the same shape as natural tile.

Which is the best metal for the roof: Rukk and other manufacturers

Before you study the instructions for installation of metal, should be familiar with the material manufacturers. Market leader in manufacturing high-quality roofing is a Finnish company Rukk. The company offers a variety of metal profile. Products characterized by high quality workmanship and quiet operation, which is achieved through the use of secret technology and improved equipment durability, which is about 50 years, affordable cost, ranging 280-600 rub. / M².

Roofing made of own raw materials. Each batch of products is subjected to strict quality control, which is performed by the action of strong rainfall, changes in temperature, salt spray and sulfur dioxide.

Original metal roofing Monterey company produces Rannila Steel. Products are characterized by high technical and operational properties. Well proven in the construction market two Finnish firms Poimukate and Takotta, which offer high-quality metal roofing average price category. One of the oldest manufacturers of the most reliable and durable roof covering is a Swedish company Areco and Mera System. Price of metal roofing installation starts from 800 rubles., Which is associated with the high cost of the material.

Do not lag behind foreign brands and domestic manufacturers, such as Interprofil, Metal profile and Grand Line. They offer the roof covering, which corresponds to an international standard, at a lower cost because of the lower cost of transportation.

Operational characteristics cold roof of metal

Roofing may be cold and warm, which determines metal stacking technology. Traditional insulation variant involves only the inner surface or non-residential attic floor. External roof part is mounted without a layer of insulation. In this case, it provides for the establishment of natural ventilation design skates which eliminates condensation during temperature changes.

Before you fasten metal tile on the roof, should be explored especially its structure. Thermal insulation consists of two layers - the waterproofing that prevents the occurrence of condensation, and the coating of metal. Between these materials are arranged kontrobreshetka and lathing. In place of the clamping ramps performed ventilation to the free air, which provides the evaporation of moisture accumulated in the internal space.

Thermal insulation consists of two layers - the waterproofing and metal

Thermal insulation consists of two layers - the waterproofing and metal

Used for waterproofing layer polyethylene film or PVC membrane. Material should not fully stretch. It should slack 25-30 mm to improve its conductivity and to facilitate draining of moisture. Waterproofing fastened to rafter elements of the system using a stapler by fixing screws on the crate.

Option Cold roof of metal: the installation of a vapor barrier

Unscrupulous roofer often recommended developer vapor barrier when installed roof unit of metal cold type. They attribute this to the fact that the active layer reduces the amount of vapor that is deposited on the sheet of roofing material, thereby increasing the life of the coating operation. However, this layer only worsen the operational parameters of the roof.

Vapor barrier can not be completely sealed. Pairs of moist air will definitely settle on the inner side of the roofing, getting through leaky joints as a result of vibrations in linear dimensions truss system. Besides vapor barrier membrane itself is capable of passing moisture in small quantities. This layer does not preclude the likelihood of condensation on the sheets of metal, which entails a negative impact.

In case of installation on the cold vapor barrier membrane roofing is substantially reduced efficiency of natural ventilation. Little to improve the situation can kontrobreshetka with special air holes.

The presence of this layer makes it difficult to audit visual state wooden rafter elements of the system. The roof can be a long period of leaks that were not detected in time. As a result, the tree begins to decay, losing its primeval quality carriers. Truss will require complex maintenance, requiring replacement of entire sections, since various antiseptic impregnation prove ineffective in this situation.

Important!Vapor barrier membrane is an expensive material, which would entail a significant increase in the estimated cost of the roof of metal.

Structural features of the warm roof of metal

Before the roof cover with metal, should examine structural features of warm embodiment. It is represented by a multilayer roofing cake composed of layers of steam, thermal and waterproofing. This design allows to equip in the attic of a dwelling. Insulation film is placed on the inner side purlin, being protected by insulation vapors coming from the inside. Material made on basis of polypropylene, polyethylene or IZOSPAN and secured with a stapler to the rafters.

Important!When equipping a warm roof should provide installation of roof window in a metal tile.

Heat-insulating material located between the joists and take all mezhstropilnoe space. The material thickness is selected depending on the climatic conditions of the region, and specifications of the building. Thermal insulation may be undeveloped via foam, glass wool, basalt, limestone, and extruded polystyrene. On top of this layer is laid waterproofing membrane to prevent condensation from entering the thermal insulation on the back side of metal.

Warm roof able to minimize heat loss from the attic space, improve it microclimate parameters, to reduce the financial costs for the maintenance of premises. This design is expensive, difficult to install, requiring strict compliance with existing technologies.

Important!Poorly executed installation of metal roofs will lead to failure of the bearing parts truss system that creates big financial costs associated with the repair work.

warm roof structure must have such ordered layers: a vapor barrier, a lower crate, insulation, waterproofing, kontrobreshetku, and metal tile lath. Between the layers must be provided to create a gap of natural ventilation, which is achieved by selecting optimal thickness of the material. Insufficient thickness will lead to the formation of large voids that will cause the formation of the moisture, reduce operating characteristics of the coating.

Apparatus roof battens as an important element of metal

Before you put a metal tile should properly arrange the foundation under it. Formation of the crates is one of the most important steps of the installation of metal roofs. It is a kind of framework for the future of the roof. On the inner side is fixed thereto the waterproofing layer, and the outer - metal. From the correctness of the work will depend on the performance of the entire roof structure.

There are two options crates: continuous and sparse. The first type involves the construction of boards abut closely to each other. This technology provides increased frame strength, however, increase the cost of the material. In rarefied all wooden furring elements are arranged at a certain distance from each other. This value is determined by the interval between waves of metal, since the depression elements is the strongest portions of the profile.

Important!When mounting the metal lath is advantageously used sparse, that is connected with sufficient strength cladding material, which does not require additional strengthening frame.

For mounting battens under the metal used timber 50x50 mm, edged board section 32h100 mm and 50x100 mm. Along the eaves are fixed two boards 50x100 mm at the bottom of the roof slope, performing the role of the base. Their height should match the height kontrobreshetki.

Before the roof cover with metal, over the waterproofing layer stuffed kontrobreshetka along the trusses, repeating their location from the ridge to the bottom of the roof, which is the basis for lathing. For this purpose, the bars of 50x50 mm. The distance between the vertical elements is typically 60-90 cm.

On top of this structure, with a certain step batten boards mounted horizontally via 32h100 timber or 50x50 mm. Wooden members to be processed antiseptic composition for protecting wood against rot, mold and mildew formation.

In place of the ridge arrangement is necessary to provide strengthening battens that is performed by fastening two boards on each side of the ridge strip. Lathing and also runs under the valley, so that between the two ramps forming an inner seam. In place of its location lathing is done solid.

Mounting of additional elements of roofing systems

Before you style your metal roofing, developing are additional elements of roofing systems that are fastened together different contiguity of the roof. They are fixed to the assembled crate and provide a safe and comfortable operation of the roof. These include the valley, cornice, the end and the ridge strips, contiguity.

Skating strips are mounted on the upper joints rays. They hide the gap between the sheets of roofing material, providing protection against water penetration and promote natural ventilation roof space. Ridge strips can be rounded or flat. They are mounted on the roof screws with rubber gasket.

Important!Under the ridge seal strips be laid for the purpose of reliable sealing joints.

Contiguity needed to create a tight connection of the roof to the walls and pipes. There are upper and lower plate. First, from the lower apron slats is created, which is fed under the tie facilitates movement of water to the outer ledge or valley. Upper elements are mounted on top of the roof covering, fulfilling a decorative function.

Helpful hints for coating metal tile roof

The more complicated the design of truss system, the more time consuming is the process of coating. As a result, a large amount of unproductive waste.

The minimum inclination angle of rays is the value of 14 degrees

The minimum inclination angle of rays is the value of 14 degrees

Before you fasten metal roofing, you must check the size of crates. The axes distance between the strips should not exceed 35 cm, which is a standard value for most metal sheet. The first rail should fill close at a distance of about 20 cm. Dimensions are strictly complied with. Each screw is screwed solely under the wave, wherein the metal sheet adjacent to the rail.

The distance between the battens and the edge increases as the distance from the edge, which improves the deflection of the roof. The minimum inclination angle of skates is the value of 14 degrees. The higher the value, the lower the load on the profile is created, and it reduces the risk of depression.

According to the metal mounting instructions Monterrey and other profile options, you must cut sheets using a portable circular saw with carbide teeth, manual or electric scissors of metal. Using a grinder to cut sheets are strictly prohibited. This is due to the fact that the profile of the edges of breaks anticorrosive layer significantly, resulting in the near term damage to the element.

Metal shavings after cutting must be removed carefully with a soft brush. The resulting profile of scratches on the recommended to cover the special polymer compound that is bundled with the metal tile.

In mezhstropilnoe space fit insulation. The most commonly used basalt wool. The optimal layer thickness is 10 cm. For buildings located in cold regions, the thickness of insulation can be increased to 25 cm. The material should be laid with offset joints, to eliminate the risk of cold bridges.

On the wrong side of the metal often is formed condensate. In order to exclude the likelihood of its occurrence on the heater is placed insulation, through which you can defer the roof repair of metal for several decades. The best embodiment is a membrane, which is characterized by a good water vapor permeability. It is able to skip the pairs who got into mineral wool, but does not allow condensate to return to the heater.

The material also is used to prevent heat loss. Since mineral wool is characterized by a low density, air is able to blow through it, and carry heat.

The first step is isolated valley. To lay the material necessary for its entire length, starting from the top. Butt joints should glue construction tape from the same manufacturer as the membrane. Further, the material is placed in a horizontal overlapping order of 10-15 cm and fixed staple gun. The first segment is required to lay parallel to Cornice strip overlapping 5-10 cm at her. Subsequent strips are mounted in series as it moves to the roof ridge with overlap of 10-15 cm.

How to cover with metal roof in the case of closing the sheet metal just skate? The process of laying the roofing material from the ridge begins. The first sheet is checked for placement relative to the end face and the eaves of the roof to metal. Apparatus roof implies mounting material overlap by 50 mm. He temporarily fixed softwood in the ridge of the center. Side second sheet is superimposed and aligned relative to the first. The elements should be connected among themselves.

As the fasteners are used for metal screws to EPDM gasket and a color head size 4,8h28 mm for wooden battens. In the case of a metal frame profile size fastener is 4,8h20 mm.

If it seems that the profiles are not joined to each other, you must immediately raise one sheet over the other and gently tilt it to move upwards. Tuck fit for the fold. The elements are fixed with screws under each tab on top of the transverse waves. Thus stacked sheet 3-4 bonded together. The whole unit is aligned to the eaves line, followed by fastening to the sheathing.

According to the step by step instructions installation of metal can be in any direction. If the roof is mounted on the left to the right, then the overlapping stacking is performed with the previous sheet, if in the opposite direction - overlapping the previous one.

Important!Every three connection profiles are checked for parallel to the eaves.

The elements are attached to the crate on the screws, which are screwed into the wave trough, where the product adheres to it. The lowest point of attachment should be via a wave over the tread. Along the edge of each ramp screws must be screwed into each wave. The average cost of metal roofing installation makes 180 rubles. / M².

Laying metal step-by-step for roofs with a long ramp

How to beat them with metal roof with a long ramp that exceeds the sheet size? In this case, once docked products occurs over the length. It is important to accurately set the level of profile sheets. Any errors will be visible from the ground, which will not be able to hide in the future.

How to strengthen the metal roofing? Initially mounted one sheet of the first row, which is aligned to the eaves and end. It overlaps with the second overlapping element and temporarily fixed by self-tapping sheet at the center of the ridge. Junction of the top and bottom is fixed with screws. Next, the third sheet is placed over the first, forming beech L. Here we should pay attention to the fact that the elements connected strictly specified places. They are fixed to each other with short screws.

The upper part of the fastening element is twisted with elastic sealing without strong tightening. Then the screw is fixed in the center of the middle sheet that allows you to shift all three profiles simultaneously. The roof is thus mounted with high accuracy relative to the eaves.

To simplify the assembly process of the first sheet can be pulled by the rope level. In this case, you should measure the width of the ramps. The discrepancy values ​​along the extreme planes should not exceed 2 mm.

Useful advice!Before the final fixing of sheet metal advisable to lay along the length of the first series has several elements that will enhance the adjustment accuracy and eliminate the risk of unpleasant errors.

Each square. m roofing material must be secured by means of screws 6-8. Installation is carried out through the wave, allowing subsequent rows of screws are shifted in a checkerboard pattern. The starting price for the work m2 metal installation in this case is 250 rubles.

Fixing sheet metal must take place in a strictly specified places above the upper point of the profile. Offset Profile of 1-2 cm can be critical, as the screws are unable to withstand the coating, which will lead to negative consequences.

Further, fixation is performed to the front strap end board with overlapping up to 10 cm from the bottom upwards. The final step is to mount the ridge lath, which may be attached directly to the sheets or mounted on perforated holders. At the ridge, should leave an opening for natural ventilation. The slit must close mesh made of non-woven material. Then, the arrangement of the overflow of the roof system.

Installation of drainage system for the roof of metal house

During a roof with metal roof arrangement provides reliable drainage system, which consists of a gutter, holders, plugs, exhaust funnel connectors, spider, connecting pipes with elbow, drain and tee holder, funnel, stopper overflow.

Each downspout assumes 10 m trough. In places of attachment V-shaped cut 10 cm wide aperture, which is inserted into the funnel. It is secured by 10 cm from the edge of the gutter. Holders set until assembly eaves every 50 cm, providing a slant chute equal to 5 mm. On either side are fixed plugs.

Brackets for supporting the gutter should not be fastened to the furring strip first, because metal strip will abut the profile sheet of roofing material, which will lead to its strain. Over time, this can cause damage to the thin rolled roofing resulting oscillations. Under the brackets need to perform special grooves. Their upper portions do not protrude above the surface of the batten elements.

The front edge of the outlet hoppers must be brought under the bent outer edge of the gutter and fix carved flange. When attaching the gutter connect them overlap by 3 cm, and fixed with lock connectors and rubber gaskets. Spider is set to funnel rainwater pipes and protects the system from getting into the leaves and debris.

Useful advice!Spider should be cleaned twice a year.

For the transition hopper to a water pipe used two bends and the connecting pipe. Holders for the pipe is established through each meter wall. In the lower part of the knee is fastened to drain water, relegating it to the 30 cm side. Tee applies in the case of a drain on the two funnels. Limiter to prevent overflow is installed in a place where water flows continuously. He put on the chute or in the corner.

Construction of security elements for laying metal

The roof of the metal involves equipping additional elements for safe maintenance and operation. These components include snow stop, catwalks, railings and staircases.

In order to avoid an uncontrolled descent of the masses of snow from the roof of the building and possible injury to people in the vicinity of the structure, carried out installation of snow guards for metal. Regulations provide their linear arrangement through a distance or in a staggered manner. Items can be presented in various formats strips or tubes connected to each other. Snow stop mounted across the roof area above the eaves.

Important!Installation of snow guards for metal compulsorily carried out over the entrance to the house, skylights, each level of a multi-tiered roof.
