WeatherMaster® Granular SE provides a secondary layer of waterproofing protection to help prevent damage from ice dams and wind-driven rain. It helps protect the entire deck of a properly ventilated roof, especially problem areas where water collects or drainage is slow. This composite underlayment is self-adhering and reinforced with a fiberglass mat.

Features:

• UV Protected Surface
