When you live in a climate like ours, ice dams are not an uncommon sight. But did you know that if left unprotected, damage from ice dams and wind-driven rain can be a very costly problem to fix. That’s why we use CertainTeed WinterGuard Ice Dam Protection.

WinterGuard waterproofing shingle underlayment is a flexible synthetic material that forms a vapor-tight, protective barrier beneath your shingles. WinterGuard is warranted against manufacturing defects and will remain watertight for the same period as your shingles — up to a maximum of 50 years.
