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.
Product Features
Product Features
- Protection against ice dams is required by most building codes2 at eaves wherever the January average temperature is 25°F (-4°C) or lower or where there is a possibility of ice forming in the eaves — i.e., the area labeled “North”. In Southern/warmer climates, leak barriers provide critical protection against wind-driven rain.
- Guards vulnerable areas of your roofi including eaves and rakes, in valleys, around chimneys and skylights, and more.
- Self-seals around nails to help avoid leaks.
- Helps resist buckling and wrinkling that can detract from the look of your finished roof.
