There’s more to your residential roof that just shingles and flashings. It also has a component hidden underneath that plays a crucial role in keeping the whole structure intact and providing your home with the utmost protection against the elements. Here’s what you need to know about the roof underlayment, including its many different variations that are worth considering for your next roof replacement.
A Vital Part of Your Roof
Your roof’s underlayment is a layer of water-resistant material tucked between the shingles and roof deck. It’s a component that serves as a final barrier against water infiltration, protecting the wooden structure from mold, rot and other structural issues. It also provides thermal insulation that helps retain indoor temperatures during winter and keeps out the heat during summer.
Popular Underlayment Options
Ideally, your underlayment should be replaced along with the rest of your residential roofing system after several years of protecting the structure against water intrusion. You’ll find all kinds of underlayment options on the market, with these three being the most common:
- Felt – This material has been a roofing industry staple long enough to prove itself as highly durable and reliable. It’s mostly made of organic felt that’s saturated in asphalt to make it water-resistant for several years. But depending on the manufacturer, it can also contain additional material, such as fiberglass reinforcement. This can help increase its overall longevity and strength.
- Synthetic – Typically, non-bitumen synthetics can cost more than the traditional underlayment types. While slightly more expensive, they offer more benefits and features, which is why many homeowners choose this option for their roofs. Unlike felt, synthetic underlayment is entirely waterproof and insulated, which means even ice won’t easily penetrate the surface. It’s also more breathable and keeps your attic free from moisture and humidity.
- Rubberized asphalt – This popular material is also more expensive than felt. However, it’s worth investing in if you want exceptional protection and leak prevention even during severe weather. It mainly consists of rubber polymers and asphalt, making it a familiar and rubber-like material. And with one side having adhesive, it can be applied directly to the deck.
