The colored stone metal tile should adjust the bladder of the bottom tile to be consistent with the bladder of the side ridge according to tile row and ridge mark. As a new type of roofing material, its sealing performance is relatively good, but if rainwater leaks, mainly due to improper handling in the installation process, how should leakage be prevented? First of all, before installation, check whether the surface is clean without sundries and whether the colored stone metal tile is polished to prevent cracking during installation. Secondly, in the installation process, attention should be paid to the matching between ceramic tiles, and no sticking edges or defects are allowed. If the competition fails, it should be replaced to prevent water seepage in rainy days. After the installation is completed, check whether it is sealed to prevent leakage in rainy days, which is very troublesome to handle. In order to prevent rainwater leakage from colored stone metal tile, it is mainly to deal with the details in the installation process, so it is necessary to standardize the treatment. In fact, the side surface of the colored stone metal tile roof adopts a self-tightening system which is lapped up and down, which can effectively prevent rainwater from leaking. So you don't have to worry.
