WeatherWatch® Mineral-Surfaced Leak Barrier is a key part of the GAF Lifetime Roofing System.1 It’s eligible for Lifetime limited warranty when used on Lifetime Shingle roofs1 and it’s an eligible component of GAF residential enhanced warranties.
By Creating a barrier at the most vulnerable areas of your asphalt shingle (at the eaves and rakes, in valleys, & around chimneys, etc.), WeatherWatch® Mineral-Surfaced Leak Barrier helps prevent leaks due to water backing up in your gutters, wind-driven rain, and, in the North, damaging ice dams. It will also help protect your home from expensive wall and ceiling staining from leaks.
