WeatherMaster® Flexible Ice & Water

WeatherMaster® Flexible Ice & Water is a film-faced, high-temperature roof underlayment suitable for use under any type of roofing material.
The plastic film surface of WeatherMaster® Flexible Ice & Water self-adhesive underlayment provides skid resistance, allowing for better traction and safer installation. An SBS-modified, self-adhesive coating creates a watertight seal around nails. Because of its flexibility, WeatherMaster® Flexible Ice & Water is ideal for critical area protection, such as eaves, rakes and valleys.
