Why What’s Under Your Shingles Matters

When most people think about their roof, they picture shingles. But shingles are only the outer layer, there are a few other steps underneath that are just as important in protecting your home.

So, what is it?

Underlayment is a protective barrier installed between the roof deck (wood sheathing) and your shingles. It’s the hidden layer that helps protects your home against water, wind, and leaks.

Why it matters:

Waterproofing: If shingles blow off or water gets underneath, the underlayment is the last line of defense.

Longevity: A high-quality underlayment (like synthetic or ice-and-water shield) helps your roof last longer.

Extra Protection Against Storms: In areas like Nova Scotia, where strong winds and heavy rain are common, underlayment steps in when shingles can’t.

Types of Leak Barriers & Roof Deck Protection we typically install

When replacing a roof, ask your contractor what type of underlayment they’re using, most of the time it’s worth the upgrade.

A great roof isn’t just shingles. It’s every layer working together.

From the deck to the underlayment to the final shingle on top, each layer adds strength, protection, and value to your home. When they all work together, you get more than a roof, you get peace of mind.
