Whether it’s in a residential or commercial property, underlayment is an integral part of every roofing system. It plays a crucial role in maintaining the overall health and stability of your roof’s entire structure. However, because this roofing component isn’t usually visible, most homeowners tend to overlook it.

In this article, Expert Contracting expounds on the role that roofing underlayment plays as well as other important details about it.
What Is Underlayment?
A water-resistant material, the underlayment is installed under other roofing materials. Its main function is to act as an additional layer of protection from the elements, which is crucial in preventing water damage. The underlayment is the final barrier that a leak must overcome after penetrating the shingles and other roofing layers.
3 Types of Underlayment
Asphalt-Saturated
Before synthetic materials became commonplace about 15 years ago, asphalt-saturated felt was the most widely used underlayment. However, many homeowners still opt for this underlayment material because of its flexibility and water resistance. It’s also affordable and easily accessible.
Non-Bitumen Synthetic
Nowadays, this is the most common type of underlayment used for roofing installations. Your roofer would likely recommend this one. Its features are similar to asphalt-saturated underlayment, but it has a higher resistance to water damage. Moreover, non-bitumen synthetic underlayment is designed for full application on the entire roof, making it a cost-effective option.
Rubberized Asphalt
This is a premium underlayment type that offers all the benefits of the two other underlayments. But unlike the first two, rubberized asphalt underlayment is completely waterproof due to its higher percentage of asphalt and rubber polymer.
