WeatherMaster® SE Granular Surfaced Peel & Stick SBS Reinforced Underlayment

Atlas WeatherMaster® Granular SE is a reinforced Peel and Stick underlayment designed for maximum ice and water protection under any roofing material. This composite underlayment is self-adhering and reinforced with a fiberglass mat.

With SBS technology, WeatherMaster® Granular SE helps protect the entire deck of a properly ventilated roof, especially problem areas where water collects or drainage can be slow. It provides a secondary layer of waterproofing protection to help prevent damage from ice dams and wind-driven rain.

Its surface of opaque granules provides excellent traction plus protection from UV degradation and weathering. This self-adhering modified bitumen underlayment creates a watertight barrier by sealing to the deck and also around nails to provide continuous protection year after year.

Among the numerous benefits of WeatherMaster® Granular SE is a UV Protected Surface that can withstand a 45-day exposure. It is 55 Mil Thick, 38 percent above industry requirements and has a self-adhesive backing that seals directly to the roof deck. With dual modified asphalt this Peel and Stick underlayment provides superior granular adhesion for better traction. It remains stable in temperatures as high as 240°F. Its fiberglass mat provides better tear resistance than saturated felt.
