Roofing Underlayment: What is It and Why is It Important?

When discussing roofs, homeowners tend to think that the roof is only composed of three parts: the shingles, the roof deck and the flashing. While these three are important components of the roof, residential roofing services providers say there is one that is equally important but often overlooked: the underlayment.

Here’s everything you need to know about the roofing underlayment.

What is the Roofing Underlayment Why is it Important?

The roofing underlayment is an integral yet often overlooked part of your roofing system. It’s a water-resistant barrier that is installed beneath your roof to protect it against moisture damage in the event of storms. Simply put, without the underlayment, you’ll be leaving your home vulnerable to leaks and moisture damage.

To install an underlayment in your home, simply turn to residential roofing contractor Dior Construction for their assistance.

Kinds of Roofing Underlayments

Much to the surprise of some homeowners, you can actually choose between three different kinds of underlayments: asphalt saturated, non-bitumen synthetic and rubberized asphalt. Of the three, asphalt saturated used to be the most common material used in underlayments until the emergence of synthetic materials. Despite this, asphalt saturated is still a reliable material as it is flexible, water-resistant, and readily available on the market.

On the other hand, non-bitumen synthetic underlayments are the common type of underlayment that roofers install in homes. Compared to asphalt saturated underlayments, non-bitumen synthetic has better water resistance and is designed for application on the entire roof, meaning it’s a cost-effective choice for most homeowners.

Finally, homeowners can also opt for rubberized asphalt. Unlike the other two, this is a premium choice as it boasts the benefits of the aforementioned underlayment types with the additional advantage of being completely waterproof due to its high percentage of asphalt and rubber polymer.
