Product Review - CertainTeed brand WinterGuard-Your roofing Armor Against the Forces of Nature!

The Enemy

Ice dams and wind-driven rain are the culprits, allowing water to get under a roof's outer shell --whether it's shingles, slate, tile, cedar shake or metal.  And unless your roof deck is protected with a waterproof barrier, damage is the inevitable consequence.

Ice dams are those nasty build-ups that form on the gutters and eaves of of roofs as freeze-melt cycles take place.  The result is trapped water, which has been forced under the shingles, that will penetrate the deck unless properly sealed.

Wind-driven rain can also drive water up the slope of a roof, forcing its way under the shingles.

The Defense

CertainTeed brand WinterGuard waterproofing shingle underlayment is the solution for winning the battle against water penetration in your roof's most vulnerable places. CertainTeed brand 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.  Placing CertainTeed brand Winterguard a minimum of 24" past the interior wall line at the eave provides your first line of defense.

CertainTeed brand WinterGuard is 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.
