Metal is one of the newest and most popular roofing materials used for roofing houses and buildings , the high cost is covered by long periods of operation and almost complete lack of preventive maintenance.
Metalocherepitsa is a laminate consisting of a steel plate with a complex surface, simulating a wave or ceramic tiles, paint, or covered with plastics, some models may be further coated with a layer of zinc an additional method of protection against corrosion. Metal addition to high cost of road and installation, as most often it is used to create a warm roofs, which are, in turn, the outer surface of a residential loft building. When choosing a roofing material, metal roofing should be understood that this is one of the hardest coatings, and therefore should be provided with sufficient strength of the walls and roof system. Rafter system for such roofs is performed with a rare crate of thick bars and trim boards, which in turn provides sufficient cell size for laying insulation. Installation begins with the calculation of the needs of a roofing material, verifying the horizontality and verticality of all elements of the roof structure, as the metal tile hard enough to bypass the admitted defects. Metal roofing is used for the installation of roofs with large angles of inclination to the horizon, as some models with complex surface profile can trap sediments in the shallow surface. On top of the crate fit vlagoizolyatsionnogo layer of material with an overlap of 150 mm, fixed by the building stapled to the sheathing. To the inner surface of the roof does not accumulate condensation on top of the material vlagoizolyatsionny make extra crate of timber 50x50 mm, and mounted along the cornice board large, thus reaching Bole tight connection of the lower sheet of tile. After laying the second layer of the inner and outer sheathing installation work can be carried out in parallel. When the inner workings of cells formed crate establish thermal insulation material, most commonly used mineral wool slabs, the thickness of plates, usually equivalent to the thickness of the materials used for sheathing. On a layer of insulation vapor barrier is laid with overlapping seams, and then glued seams with tape and fastened to the building stapled to the sheathing, then made the installation of drywall or plywood, finishing. Outside of work limited to installation of metal, assembly takes place from the bottom up, with the lower number should be hanging from the roof to not less than six inches, for further installation stormwater runoff and snowmelt. Shingles laid with an overlap of 150 mm on each side, special care must be made in laying the ground surface bends around the chimney, valley, attic window openings, ends and other elements. Tightly enough to be fitted to the peak of horse, as well as laying the principle should be maintained discharge.
