By creating a barrier at the most vulnerable areas of your roof (at the eaves and rakes, in valleys, around chimneys, etc.), WeatherWatch® Leak Barrier will help prevent leaks due to water backing up in your gutters, wind-driven rain, and, in the North, damaging ice dams. It will also protect your home from expensive wall and ceiling staining from leaks. WeatherWatch® Leak Barrier is a key part of the GAF Lifetime Roofing System and has earned the Good Housekeeping Seal1 (applicable in the U.S. only). Eligible for a Lifetime limited warranty when used on Lifetime Shingle Roofs and eligible for a 25-year ltd. warranty when used on non-Lifetime Shingle roofs.2

REDUCE HEADACHES
Reduces the risk of costly repairs due to interior wall and ceiling staining from leaks
- Code Compliance and Risk Reduction: Protection against ice dams is required by most building codes3 at eaves wherever the January average temperature is 25°F (3.8°C) or lower or where there is a possibility of ice forming in the eaves — i.e., the area labeled “North”.
- Great Look: Fiberglass reinforcement helps resist wrinkling and buckling.
- Dependable: Self-seals around nails or metal roofing fasteners to help avoid leaks.
- Saves Labor: Split-back release film helps to speed installation.
- Convenient: 1.5 square (150 ft.2 [13.9 m2]) and 2.0 square (200 ft.2 [18.58 m2]) roll sizes.
