When it comes to preventing water leakage on resin tile roofs, the design of the roof slope plays a critical role. It is recommended to have a steep ridge of about 60 degrees, as this will effectively guide rainwater to drain quickly. Additionally, the eaves should be appropriately lowered to about 30 degrees. This design utilizes the impact force of the water flow to efficiently drain accumulated water through the tile, thereby reducing the risk of leakage by up to 80%. With this reasonable slope design, upvc sheet suppliers and pvc roofing flat sheet manufacturers can significantly improve the performance and durability of their products. By focusing on proper slope design, water leakage issues can be effectively mitigated, ensuring the quality and longevity of synthetic resin roof tiles.
