Synthetic resin roofing tiles have a typical service life of 25 to 30 years, provided they are properly maintained. The weather-resistant coating on their surface is crucial; damage to this coating can cause fading and brittleness. Many users mistakenly believe these tiles are “maintenance-free,” but in fact, they require regular cleaning to remove dust and stains, as well as measures to prevent weed growth and water accumulation that can cause rot. It is strictly prohibited to use hard brushes or high-pressure water jets for cleaning, as this can damage the protective coating.
Synthetic resin roof tiles are widely used due to their light weight and corrosion resistance, but they require regular maintenance to extend their service life. Avoid frequent cleaning; rinse them with a soft-bristled brush, and do not use a stiff brush that could scratch the protective surface layer. In humid southern regions, moss tends to grow easily, affecting both appearance and drainage. The drainage system also requires attention to prevent clogging. With proper maintenance, the roof can remain attractive and functional for two to three decades.
