The roof of metal

Metal applied to the device pitched roof with a slope of not less than 1 / 4 (at 1 m height of 4 m width). Mounted panels, which must be ordered with a length equal to the length of the slope. Finishing elements shaped book, but the individual elements (except the horse, seal ridge and the wind profile for the board) can be manufactured from a flat metal the size of 1000x2000 mm, having the same color and anti-corrosion coating that profile. Metal roofing can be cut with hand or electric shears, a hacksaw for a metal (as a guide can serve as a board, etc.). best cut with a special electrical knife. It should be borne in mind, trro avoid damaging corrosion layers can not cut the profile of abrasive disc saw. Preparation of the carrier base. The upper part of the rafters covered with thick planks, 19 or 22 mm and to prevent moisture veiled roofing material or other waterproofing materials. The prepared surface nailed decaying blocks of at least 25x25 mm 600 mm from each other, and to them - bars the size of 40x50 mm with a step 400 (350) mm for each halyard. Bar at the bottom faloy must have a cross section of 50x50 mm. For outbuildings can apply lightweight version of the crates in which the rafters nailed to the cross section of 32-board 100 mA at 400 (350) mm for each halyard, the first board sheathing must be thicker than about 18 mm. Sheets can be lifted to the roof by hand, for example, on two parallel boards. Mounting Profile perform self-tapping screws with metal and neoprene washers in the inflection of the profile below the transverse groove in the pits at a distance of 25-30 mm from the beginning of the halyards rate fixing screws 6.5 to 1 m2, fixed on the edge of each second wave, each covering the edge of the profile is attached in each halyard. For screwing screws you can use an electric drill with adjustable speed and reverse motion. Metal roofing can be used to repair old roofs, and "what is often not necessary to pluck the old coating. The old roof made of asbestos roofing, flat roofing steel, etc., can serve as an additional waterproofing.
