Torch-on waterproofing membranes are a popular and highly effective solution for protecting flat roofs, decks, and other exposed surfaces from water ingress. These membranes are typically made from modified bitumen, reinforced with polyester or fibreglass, and applied in layers using a gas torch to heat and bond the material directly to the substrate.

The result is a seamless, durable, and watertight barrier that can withstand UV exposure, temperature extremes, and mechanical stress. Torch-on systems are especially well-suited to low-slope and flat roof areas where traditional drainage is limited, offering long-term reliability and minimal maintenance.

With proper installation, a torch-on membrane can last 20+ years, making it a smart investment for both residential and commercial buildings.
