Weathermaster Atlas 200 Granulated Ice & Water Barrier 36" x 65' (195 sq ft)

A proprietary fiberglass mat reinforced, SBS-modified asphalt makes WeatherMaster® Ice & Water ideally suited for continuous waterproofing protection against ice dams and wind-blown rain year after year. The self-adhesive underlayment creates a watertight barrier by sealing to the roof deck and around nails. WeatherMaster® Ice & Water provides excellent traction and protection from UV degradation and weathering thanks to its granular surface.
