Roof flashing materials refer to the various metals and composites used to create waterproof barriers at roof joints and penetrations. Common materials include aluminum, galvanized steel, and copper. These materials are selected based on durability, corrosion resistance, and compatibility with roofing systems. In Vancouver’s wet climate, high-quality flashing materials are essential to prevent leaks and extend roof lifespan. Proper selection and installation ensure long-term waterproofing performance.
