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.

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.
Granular
If you’re looking for superior traction during application, the granular surface with embedded granules may be the perfect fit.
Sand
The sand surface offers enhanced traction during application.
Metal
For those with metal, shingle, slate, or mechanically-fastened tile roofs, the high-temperature textured surface roofing underlayment of the metal option has you covered.
High Temp (HT)
If you’re searching for high-temperature and enhanced skid resistance for shingle, metal, slate, or tile roofs, the HT option covers you.
Second Defense
Water-Resistant Roofing Underlayment
Have you ever experienced a leaky roof during a rainstorm? It can cause severe damage to your home. This water-resistant layer of roofing underlayment acts as a secondary barrier against leaks, providing extra protection for your home. It’s like having a backup plan in case of emergencies.

CertainTeed’s DiamondDeck®

Specifically manufactured to offer unparalleled weather protection, ensuring your roof is well-protected from the elements. CertainTeed’s DiamondDeck® High-Performance Synthetic Underlayment is also designed with the roofing contractor’s safety in mind.
Synthetic Underlayment
This synthetic underlayment can be used with various roofing materials, including shingle, shake, metal, and slate. What sets it apart from standard felt underlayment is its exceptional dimensional stability. In other words, it won’t warp or move around like other options.
Slip Resistant
One common issue of subpar roofing underlayments is how they can wrinkle and cause visible imperfections under your shingles. Luckily, DiamondDeck® eliminates the risk of wrinkling and has a top surface treatment that gives it outstanding slip resistance, even when wet.

RoofRunner™ is a synthetic polymer-based underlayment that’s a game-changer in the residential roofing industry – outperforming felt and other synthetics out there.

Roof Replacement
Great workmanship. House & garage done in 1 day. Everything was cleaned up after.. We highly recommend them.
Roof Replacement
Had my roof, gutters, & skylight replaced—couldn’t be happier! The team was professional, efficient, and detail-oriented.
Storm Damage
Storm damage hit us. Elevated arrived next morning & guided us through everything with great communication. His crew finished our house, garage, & small building in 1 day!
Awesome company to work with. Great communicator, excellent, timely workmanship and good follow up.
The people in this outfit are some serious pros from the office staff to their field personnel. One of their foremen “JT” was especially helpful throughout the process. They did a clean job front to back on a large roof in one day!!
The entire process was smooth and pleasant. From the estimate, to the timely coordination for the job with Erika and Simon. JT greeted me this morning and discussed the plan and then the crew arrived and they went to work to replace my aging double roof. Simon provided updates via email with pics to show the damage found. And then another update when repairs to roof deck were completed. JT and his crew had all the work completed and cleaned up before 1PM, which in itself was pretty amazing. Before JT left, we did a final inspection and I must say the results are incredible. I will gladly recommend Elevated and their team! 😀👍
