The market for resin roofing tiles is booming, but there are significant variations in price and quality. When purchasing, the key factors to consider are the raw materials and thickness, rather than the brand. Low-priced tiles often contain calcium carbonate and recycled materials, making them prone to becoming brittle and fading, and susceptible to severe damage from hail. High-quality tiles should have an ASA-based surface layer; when you scratch the edge with your fingernail, it should not turn white or leave a powdery residue.
