The torch on roofing installation process in Vancouver is a specialized technical procedure designed to create a seamless, waterproof barrier for flat and low-slope roofs. The process involves several critical steps to ensure long-term durability against the wet British Columbia climate:
- Surface Preparation: The process begins with a thorough cleaning of the roof surface to remove all debris and old materials, establishing a clean base for the new system.
- Layer Application: A base layer of modified bitumen membrane is applied to the prepared surface. This is often followed by additional plies to provide extra reinforcement and strength.
- Heat Sealing: Technicians use propane torches to heat the modified bitumen membrane. The flame melts the material, allowing multiple layers to be sealed together into a single, cohesive waterproof unit.
- Integration: The membrane is carefully integrated with existing roof features such as skylights, vents, gutters, and drainage systems to maintain a continuous seal.
- Safety and Standards: Because the process involves open flames, professionals must adhere to strict safety protocols, including fire prevention measures and proper ventilation. Installers often follow BC building codes and may hold specific certifications like CERTA torch training to ensure fire-safe techniques.
