Before installing Gaoyi resin roofing tiles, prepare the necessary tools, assess the condition of the roof, and ensure the substrate is level. Use self-tapping screws with waterproof washers. During installation, pay attention to the overlap length of the tiles and staggered laying; secure the screws vertically and allow for expansion. Use specialized fittings and waterproof caps to seal the ridge and eaves, ensuring a watertight seal.
