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.

Maximum Protection

A modern roof system requires two underlayments for maximum protection from the elements. Elevated Roofing will first install a waterproof ice and water membrane along the roof’s perimeter to protect against ice damming in snowy areas and high-water flow in valleys and around roof penetrations like skylights and vents. The second underlayment covers the rest of the roof deck with water-resistant and tear-resistant material that provides the installer with a secure walking surface. With this advanced system, you can rest easy knowing your roof is well-protected and built to last.

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.

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.

    Wow! Exceptional service from day 1! Loved meeting the owner and discussing our options for a new roof. After a couple of delays and great communication with Erica, we finally had our date. JT was “the man”. Very nice, professional and always kept me up to date on what was happening. The crew was wonderful and hardworking! They did a great job with cleaning up each night and final clean up! Since I don’t plan on getting a new roof soon, I can only recommend them to others!! Thank you Matt and your wonderful team at Elevated Roofing!!
