Underlayment is an integral part of every roofing system. It’s key to the overall health and stability of your roof’s entire structure. However, since this roofing component is not visible from the street, it’s common for homeowners to overlook this part.
In this article, M&A Exterior Home Improvement discusses the role that roofing underlayment plays as well as other essential information about it.
What Is an Underlayment?
The underlayment is a water-resistant barrier material that is installed under all the other roofing materials. Its main purpose is to serve as an additional layer of protection from the weather, and it is crucial in preventing water damage. The underlayment is the final layer that a leak must overcome after penetrating the shingles and other roofing layers.
3 Types of Underlayment
Before synthetic materials became commonplace 15 years ago, asphalt-saturated felt was the most commonly used underlayment. Nevertheless, it still serves as a great underlayment option because of its flexibility and water resistance. It’s also affordable and readily available.
- Non-Bitumen Synthetic
This is the most common type of underlayment used today. Your prospective roofer would likely recommend this one. Its features are similar to asphalt-saturated underlayment, but it’s better when it comes to water resistance. Non-bitumen synthetic underlayments are also designed for full application on the entire roof, making it a cost-effective choice.
- Rubberized Asphalt
This premium underlayment type has all the benefits of the two other underlayments. Unlike the first two mentioned, rubberized asphalt underlayments are completely waterproof due to their higher percentage of asphalt and rubber polymer.
