Resin roofing tiles are highly sought after for their advantages, but since product quality varies widely on the market, caution is advised when purchasing. Don’t focus solely on thickness; the key factor is whether the product uses imported ASA resin rather than recycled material. We recommend requesting test reports and verifying the purity of the raw materials by scraping or breaking the tiles. For roofs with steep slopes and wide spans, select tiles with a thickness of 3.0 millimeters or greater.
