Roof Flashing Repair for Rubber Roofing: Mistakes to Avoid Roof Flashing Repair for Rubber Roofing: Mistakes to Avoid
When doing roof flashing repair on rubber roofs, prevent leaks by avoiding these common mistakes. Cut the rubber flashing generously so it overlaps the roof valley, vent or eaves by 12 inches per side. Remove the protective backing film in one motion from the flashing and install it smoothly on the surface. Avoid creating wrinkles and bubbles which can trap water. Apply termination sealing tape over the top and bottom edges of rubber roof flashing so it reaches 1 inch beyond each end, to avoid peeling and lifting of the flashing. Roof leaks are most common around vents, skylights and chimneys. Measure the rubber flashing carefully for a precise fit and seal edges snugly and smoothly with the termination tape. Apply a coat of liquid EPDM (ethylene propylene diene monomer) to all flashing edges after they are taped for true watertight coverage. Find the best roofing caulk you can use, avoiding those that break down in UV light. Look for roofing caulk with UV protectant. Avoid applying rubber roof flashing in temperatures below 55 degrees F. The adhesives cure and seal most effectively above 60 degrees F. Avoid Cutting Rubber Roof Flashing too Shallowly
