The color steel plate roof has been damaged by the environment and climate for a long time. The temperature difference of climate leads to the shrinkage and deformation of color steel tiles. In addition, strong wind and heavy rain cause long-term vibration of color steel roof. Long term wear of nail holes and joints of iron sheets will lead to damage of rubber pads and serious water leakage. Next, Jinan Color Steel Plate Factory will talk about the cause of the damaged cornice of color steel plate
Some roofs have large spans, and water will accumulate in the middle after people step on them for a long time, and the middle gravity will increase. The more rain, the more serious the roof deformation. Some roofs are made of mineral wool, which can absorb water.
In rainy days, the rainwater leaked from the roof will gather in the mineral wool, which will increase the weight and even cause the roof to collapse. The parapet at the corner of the roof rises and falls. For initial waterproof construction, cement shall be used to plaster splayed corners, and sealant or waterproof coating shall be used for waterproof protection. If the cement does not bond with the metal, cracks are likely to occur. If the elongation of sealant or paint is small, large cracks will also occur.
What is easier and more difficult to deal with is "gutter waterproofing". It is difficult for non specialized people to find the essential leakage point. Because the design size and width of the gutter are different, the construction difficulty is also different, and some are too narrow, so you need to cut off the redundant cornice of the color steel plate to wrap the entire gutter.
There are usually two aspects of leakage current. First, the gutter design is unreasonable, the sludge accumulation is too thick, the drainage is not timely, and the residual water is soaked for a long time, leading to the gutter leakage. As long as the gutter is cleaned and flushed regularly every year, there will be no excessive ash accumulation in the gutter, and rainwater can be drained in time, so that it will not be worn.
