Your best defense
The WinterGuard™ Series of waterproofing shingle underlayments
are applied under roof shingles during new construction or
re-roofing to protect your home’s interior from winter leaks
caused by ice dams and wind-driven rain.
How WinterGuard works:
WinterGuard is made of asphalt polymers, formed into a rolled
sheet. The polymers make the asphalt elastic, sticky, and
waterproof. The result is an amazing ability to both
cling. This means that WinterGuard doesn’t rip when stressed
and seals around nails driven through it. It sticks to a clean
roof deck like glue. The result is a waterproof barrier
beneath your shingle system, which pooled water and
wind-driven rain cannot penetrate.
Ice dams -- nasty build-ups of ice and snow -- form from
freeze-melt cycling on your home’s roof deck. When the ice and
snow melt, trapped water can seep through the roof, damaging
the roof deck, insulation and the interior of your home.
shingle underlayment is installed between the roof deck and
the shingles, creating a weather-tight barrier that prevents
backed-up water from getting into your home.
