How does WeatherWatch® Protect your Roof?

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.

• Code Compliance and Risk Reduction:  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.
