Winterguard
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.
- Advanced waterproofing underlayment for shingle, metal, slate and tile roofs
