Roofing underlayment on a home

What Is Roofing Underlayment?

Roofing underlayment doesn’t get as much attention as shingles do because they’re the most visible part of the roof. However, underlayment is the unsung hero of a good roof. It’s a layer of moisture-resistant material that goes underneath your shingles, helping to protect your roof from damage caused by water seeping through your shingles.

For years, roofers and contractors used felt for this purpose, but now synthetic materials have taken over. They’re more expensive but lighter, lie flatter, and offer better water resistance, saving you a big headache.

First Defense

Waterproofing Roofing Underlayment

The first defense in protecting your home from the elements is with a waterproofing roofing underlayment. This self-adhering material is installed at vulnerable areas of your roof, like around chimneys and skylights, to create an added layer of protection to guard against leaks caused by rain and ice dams.

WinterGuard®

WinterGuard

You want the best of the best when it comes to keeping your roof watertight. That’s where CertainTeed WinterGuard® Waterproofing shingle underlayment comes in. Made from a composite of asphalt polymers, this rolled sheet of roofing underlayment is built to last. Not only is it vapor-tight thanks to the asphalt, but the polymers make it stretchy and adhesive too. This means it can stretch and seal around nails that might otherwise leave gaps for water to seep in. At Elevated Roofing, we know that protecting your roof is vital to keeping your home safe and dry. We feature CertainTeed WinterGuard® as our go-to solution for tackling water penetration in your roof’s most vulnerable areas.

Several options are available to meet the needs of every roof style, slope, and preference. Whatever surface type you choose, take comfort in knowing that you’ve made an informed decision to protect your roof for years to come.

Matt was very responsive and had great ideas about our roof and gutter system. We only needed a minor fix and Matt was right on it. Highly recommend.

I would highly recommend elevated roofing for anyone needing a roof! Matt, Colton and their crew got my roof done in one day! They were fast , friendly, very efficient and very respectful to me and my property. If I could give them more than 5 stars I would. They kept me up to speed on everything from the beginning to the end and did a walk thru to make sure everything was picked up and thrown away. I couldn’t be more happy with the team from Elevated Roofing!
