Does Your Roof Need Ice & Water Shield?

Where and Why This Extra Layer Matters Most

Keywords: ice and water shield, winter roof protection, roof leak barrier

If you’ve had a roof replacement or inspection recently, you may have heard about ice and water shield. But what is it—and do you really need it?

Let’s break down where it’s used, what it does, and why it’s so important in cold-weather areas like the Quad Cities.

💧 What Is Ice & Water Shield?

Ice and water shield is a rubberized waterproof membrane that’s installed beneath your shingles. Unlike standard underlayment, it self-seals around nails and forms a watertight barrier to prevent leaks from:

• Ice dams

• Wind-driven rain

• Snow buildup in valleys

🧊 Where It’s Most Effective

Code often requires ice and water shield in:

• Roof eaves and edges

• Valleys where water naturally collects

• Around chimneys, vents, and skylights

• Low-pitch roof sections where melting snow drains slowly

In high-risk areas, we may recommend installing it on the entire roof deck for maximum protection.

🏠 What Happens Without It?

Roofs without ice and water shield are more vulnerable to winter leaks, especially during freeze/thaw cycles. Water can back up under shingles and rot your decking—causing ceiling stains, mold, and long-term structural issues.

🧰 It’s a Small Upgrade That Prevents Big Problems

Installing ice and water shield costs a little more—but pays off in peace of mind during snow season. It’s one of the best ways to make your roof winter-ready and storm-proof.
