Trapezoidal and Twinwall Hollow Roofing Sheet Accessories Material Waterproof Screw Cap

Using waterproof caps on resin tiles is essential to ensure the roof's waterproof performance and extend its lifespan. When installing screws, holes are created in the tiles, which can lead to water seepage and potential leaks. Waterproof caps seal these screw holes effectively, preventing moisture from penetrating and protecting the screws from corrosion due to humidity, reducing the risk of rust. Additionally, these caps enhance the overall sealing of the roof, ensuring better protection in harsh weather conditions. They also cover the screws, improving the roof's appearance. Overall, waterproof caps are a crucial component of the resin tile roofing system.
