WinterGuard® waterproofing shingle underlayment is the solution for winning the battle against water penetration in your roof's most vulnerable places. WinterGuard is a composite material of asphalt polymers, formed into a rolled sheet. The asphalt makes it vapor-tight, and the polymers make the asphalt elastic and sticky. This protective barrier is able to stretch and seal around nails driven through it. The Integrity Roof System is designed to provide optimum performance--no matter how bad the weather conditions are.
Sand-embedded top surface to enhance traction during application
The adhesive bottom surface is protected with a disposable silicone coated release film, which is split down the middle for simple and cost-effective application
WinterGuard® is installed under shingled roofing to prevent water damage from ice dams, as well as wind-driven rain
WinterGuard® can be repositioned before deck adhesion occurs
Warranted against manufacturing defects and to remain watertight for the same period as the warranty duration carried by the shingles applied above it (up to a maximum of 50 years)
