Why You Need Ice and Water Shield in Colorado

“Invisible” protection against roof leaks for your Colorado home

Why use ice and water protection?

A-Denver Roofing’s Ice and Water Protector is used for waterproofing under shingled roofs preventing water penetration due to ice dams or wind-driven rain from the Colorado weather. We also use it as an underlayment around chimneys, dormers, vent stacks, skylights and other roof-top structures or apertures, around doors and windows, and as an exterior vapor barrier for foundations and basements. Using ice and water protection on your home in Colorado is extremely important due to the extreme wind and rain events, as well as the cold weather during the winter. In Colorado, rain can be accompanied by extremely high winds, this wind can push rain underneath the shingles on the eaves of your home. Ice and water protector stops wind-driven rain from entering your roofing system.

What is ice and water protection?

Ice & Water Protector is a modified bitumen roll roofing product with a self-adhesive backing protected by a silicone-treated release sheet, which is easily removed during installation. The inner membrane of the roll consists of a tough, non-woven, glass fiber mat which has been impregnated and coated with a specially formulated modified bitumen with exceptional elasticity. Sand is embedded into the top surface to provide the product with a non-slip surface for safety.

Protects Against Wind-Driven Rain

Rain, propelled by Colorado’s strong wind, is blown under the shingles, allowing water to penetrate through the unprotected roof deck, causing interior damage. Roofs with lower slopes (2:12 to 5:12) are even more susceptible to this problem.

Helps Prevent Ice Dams

When melted snow from Colorado’s strong sun runs down the roof to the colder eaves, an ice dam can form and cause water to back up under the shingles. Eventually, the water penetrates the unprotected roof deck and leaks through, damaging your Colorado home’s interior.

Seals Around Nails

The rubberized asphalt layer in A-Denver Roofing’s ArmourGard Ice & Water Protector seals around roofing nails, resisting leakage caused by water backup behind ice dams, or from wind-driven rain.
