WeatherMaster® Flexible Ice & Water, a film-faced, high-temperature underlayment, is designed to go under any roofing material. This water barrier underlayment can be installed to metal, concrete, plywood, wood composition board, and gypsum. The silicone-treated, split-back release film allows for easy installation and handling.

The plastic film surface of WeatherMaster® Flexible Ice & Water underlayment provides skid resistance, allowing for better traction and safer installation. No special adhesives, heat, or equipment are necessary to install WeatherMaster® Flexible Ice & Water underlayment under normal, dry conditions of 45°F or warmer.

WeatherMaster® Flexible Ice & Water underlayment provides a secondary layer of waterproofing protection needed to help prevent damage from wind-driven rain. WeatherMaster® Flexible Ice & Water helps protect the entire deck of a properly ventilated roof or just those problem areas where water collects or drainage is slow. This SBS-modified, self-adhering underlayment creates a watertight barrier by sealing to the deck and around nails to provide continuous protection year after year.
