The service life of roll coatings depends on the quality of base materials, the right technology and type of mastic, and the quality of care for the roof. Roofing materials rolled in the summer under intense heating, which leads to the formation of blisters in the roof membrane, as in the pores of wet basement increases the water vapor pressure (heating mat to 60 C, the vapor pressure dostigaet2 t/m2). With high humidity coating occurs delamination of the carpet, followed by the formation of air and water bags, streaming bitumen mastic carpet heating by solar radiation or mechanical damage to the carpet. The size of air bubbles can reach height of 25-30 sm.V indoor toilets in the upper floors of combined roof can be seen on the ceilings Condensation moisture. The reason for this is the wrong device sewer riser joints with exhaust pipes, sockets set down, resulting in wetting of insulation and thermal insulation qualities of the combined drop in the roof. Current repair of the roof of roll material basically comes down to replacing of defects and clamped all kinds of holes and cracks of the coating.
Places where the roof covering clearing violated, then coated with cement and stick with a roofing material. Places where the roll material to be cut is rotten. Cut the material around the damaged area with a minimum width of 10 cm The resulting groove is carefully cleaned, smeared with putty and stick with a piece of rolled material, so that the edges do not fall for the old roof, ie, butt. Then again OST seat cover with putty and stick with a second layer of roll material, but in this layer should overlap the edges of the damaged area by 15 sm.V when painting the carpet has lagged behind the base, promazyvayut base paste, pressed him canvas mat, and stick the patch on top, overlapping in places cut the carpet at 10 locations sm.V roof membrane blistering cross incision made, turn down the cloth on the carpet four sides, carefully clearing the ground, dried and lubricated it with mastic bent piece of cloth is pressed against the base of the carpet and stick again, and on top of that place and stick the patch to restore the protective krovli.Pri coating repair work, as in roofing, roofing material must be cleared from spreading.
