The suitable slope of ASA Resin UPVC roof sheet
is 20 degrees to 80 degrees. Sloping roof is the most common form of roof construction in traditional buildings. The size of the slope directly affects drainage. If the roof contains water, it will inevitably lead to leakage. Therefore, generally, the slope of the roof at the ridge part is relatively large, around 60 degrees, in order to facilitate the rapid flow of water. When the slope of the eaves is slowed down, at about 30 degrees, the inertia of the impact of the water flow is used to rush out from the roof sheet, and the drainage effect can be reduced 80% chance of leakage. If the roof slope is high, the slope is greater than 45 degrees, when installing the resin UPVC roof sheet, you can drive 2 more screws per square meter. Because the slope is steep, it will be firmer to fix the roof sheet with a few more screws when it is subjected to strong winds and heavy rains.
