The underlayment of your roof plays a critical role in your home’s protection from bad weather. It may not be visible, but it works hard day in and day out to prevent water intrusion into your home.
Today, the local roof repair and replacement pros of Vertex Roofing Contractors Inc. share everything you need to know about the roof underlayment.
About the Roof Underlayment
The underlayment is a water-resistant barrier material installed directly onto your roof decking or sheathing. It is applied before the rest of the roof’s components are installed, particularly the flashings and the roof covering, and serves as an extra layer of protection from severe weather.
During roof replacement, the pros make sure to install the underlayment to prevent the roof sheathing from getting saturated with moisture. This is very important, especially when a short but sudden downpour occurs during the roofing project. Think of it as a final barrier that water must overcome after it has gone through the rest of the roofing system.
Types of Underlayment
There are three types of underlayment:
Asphalt-saturated felt – Before synthetic underlayment products became popular, roofing contractors relied on this type of underlayment in protecting the roof decking. Also known in the roofing industry as “felt paper,” it is saturated with asphalt to ensure water resistance.
Rubberized asphalt – This type of underlayment contains a higher percentage of asphalt and rubber polymers, making it more waterproof than the other two types.
Synthetic underlayment – Most roofers today use this type of underlayment to cover the entire roof deck. It is also saturated with asphalt, but the addition of fiberglass gives the material excellent tear resistance and stability.
