WeatherMaster® Ice & Water 200
WeatherMaster® Ice & Water products are self-adhesive composite underlayments. The adhesive layer is composed of a proprietary, SBS-modified asphalt reinforced with a fiberglass mat.
The granule and sand surface provides excellent traction and protection from UV degradation and weathering. The self-adhesive side is covered with a split-release sheet that is removed during installation.
WeatherMaster® Ice & Water provides a secondary layer of waterproofing protection needed to help prevent damage from ice dams and wind-blown rain. These self-adhering modified-bitumen underlayments create a watertight barrier by sealing to the deck and around nails to provide continuous protection year after year. WeatherMaster® Ice & Water helps protect the entire deck of a properly ventilated roof or just those problem areas where water collects or drainage is slow.
