The underlayment refers to the waterproof material installed between the asphalt shingles and the roof decking. While it’s not outwardly visible like the shingles, which contribute greatly to your home’s overall appearance, the underlayment remains an important component of any roofing system. A trusted “roofer near me,” Innovative Roofing & Siding, Inc., explains why.

Roof Leak Prevention
You’ve most likely faced a roof leak at some point, so you understand just how much damage it can cause. If rainwater or moisture manage to bypass the asphalt shingles, the underlayment is the next layer preventing water from leaking in. Serving as a secondary barrier against water or moisture, the underlayment helps protect your roof system from possible leaks.
Increased Roof Longevity
By keeping your roof system healthy and leak-free, the underlayment reduces the potential for mold and rot in the decking and trusses – components that make up the roof structure. This, in turn, helps maintain the roof’s structural integrity, allowing it to last longer. Just how effectively the underlayment prevents roof leaks will depend on the material it is made of. If you’re planning a roof replacement this season, a trusted roofing contractor like Innovative Roofing & Siding, Inc. can help you choose and install the right underlayment for your new system.
Available Options for Roof Underlayment
Asphalt-saturated is the traditional option for roof underlayment. It’s flexible, water resistant and cost effective, which are the reasons it remains a viable choice even with the advent of synthetic underlayment. Most roofing experts, however, may recommend nonbitumen synthetic because it’s a definite upgrade from asphalt-saturated, providing more reliable and water-resistant performance as a roof underlayment. And those who want something more premium should go for rubberized asphalt. It basically combines the best features of the two previous options, allowing for a completely waterproof roofing system.
