Your roof’s underlayment is one of the most unnoticed yet integral parts of your home. Since its location is hidden, you can’t easily see it from the outside of your property. Even so, it is a component that is as essential as the other major parts of your roofing system, like asphalt shingles and flashings.
Today, we take a look at what an underlayment can do for your roof.
The Importance of Roofing Underlayment
The main function of underlayment is to protect the roofing system from water infiltration and the damage that can result from it. This component is placed under all the other roofing materials, making it the last barrier that blocks water leaks before they enter the rest of the roofing system and reach your home’s interior.
3 Types of Roofing Underlayment
1. Asphalt-Saturated
Before synthetic materials became the most popular underlayment option, asphalt-saturated felt used to be the common choice among contractors and property owners. Several homes today are still protected by asphalt-saturated underlayment because this option remains to be reliable, flexible and water-resistant. You can also easily find it in your local hardware or home improvement store, making it the most affordable underlayment type.
2. Non-Bitumen Synthetic
Most roofing contractors recommend using this underlayment type. Non-bitumen underlayment has the best features of asphalt-saturated felt but with stronger water resistance. This is also a more cost-effective option for homeowners because it is designed for full application on the entire residential roofing.
3. Rubberized Asphalt
This is a premium underlayment type that contains all of the features of the two other options mentioned. Rubberized asphalt underlayment is made up of a larger amount of asphalt and rubber polymer, making it completely waterproof. It’s also equipped with a special protective membrane that creates a built-in waterproof seal between the underlayment and the roof decking, where it is attached. The only drawback of rubberized asphalt underlayment is that it costs significantly higher than other options.
