A Durable Roof-Valley Repair

Eliminate leaks with peel-and-stick membrane and metal flashing

Roofing contractor Stephen Hazlett shows the proper steps and discusses the best techniques for repairing roof valleys, both woven and cut. Hazlett's process involves using specialized tools such as a utility knife fitted with a hook blade, a roofer's pry bar, and a metal seamer. His technique begins with the careful removal of old shingle, the placement of a waterproof membrane, and the installation of valley flashing, followed by the replacement of the roof shingles. Hazlett emphasizes the need for a clean, orderly process to make the repair long-lasting.
