Color steel roof deformation of the main reasons: first: the roof span is big, time is long cause of water in the middle, in the middle of gravity, the rain the more deformation, appear even roof fall. The second: roof with mineral wool, mineral wool have bibulous effect, rainy day, rain roof leakage all gathered in the mineral wool, weight increase. Third: housing season roof high temperature, sudden rain, causing caigang tile temperature plummeting, caigang tile rapid shrinkage, resulting in color plate deformation, nails loose.
