Why Ice & Water Barriers Are Essential for Wisconsin Roofs

If you’ve lived through a Wisconsin winter, you know how quickly snow and ice can accumulate on your roof. One of the most common problems homeowners experience during winter is ice dams, which can cause serious roof leaks and water damage.

That’s why an ice and water barrier is one of the most important components of a high-quality roofing system.

What Is an Ice & Water Barrier?

An ice and water barrier is a self-adhering waterproof membrane installed beneath the roofing shingles in critical areas of the roof.

These areas typically include:

• Roof edges

• Valleys

• Around chimneys and skylights

• Areas prone to ice dam formation

The barrier creates a watertight seal that helps prevent water from reaching the roof deck.

How Ice Dams Cause Roof Leaks

Ice dams form when snow on the roof melts and refreezes near the edge of the roof. As melting snow backs up behind the ice, water can work its way beneath shingles.

Without a waterproof barrier underneath, that water can seep into your home.

This can lead to damage such as:

• Ceiling stains

• Mold growth

• Damaged insulation

• Rotting roof decking

Why Ice & Water Barriers Matter in Northeast Wisconsin

Homes in Northeast Wisconsin experience frequent freeze-thaw cycles during winter. These cycles make roofs especially vulnerable to ice dam formation.

Installing an ice and water barrier helps:

• Prevent leaks caused by ice dams

• Protect the roof deck

• Reduce long-term roof damage

• Extend the lifespan of your roofing system

When installed as part of a Secure Choice™ Roofing System, the barrier works alongside other roofing components to provide complete protection.
