Roofing underlayment is a membrane that’s applied to the deck of your roof before installing shingles. It is an essential component for all roofing systems and provides added protection against moisture and its damaging effects.
Why Is Roofing Underlayment Important?
The underlayment is either a water-resistant or waterproof barrier material, which is installed underneath all roofing materials. Shingles can withstand harmful ultraviolet (UV) rays, high winds and other elements, but they aren’t sealed at all corners. They can be lifted by strong winds and get brittle as they age. A strong underlayment provides your home with an extra layer of protection against weather and water damage.
Keep in mind that not all underlayments are suitable for every roof. They are available in three types, which are asphalt-saturated, non-bitumen synthetic and rubberized asphalt.
Types of Roofing Underlayment
Asphalt-saturated – This used to be the most popular type of underlayment until the emergence of synthetic materials. Asphalt-saturated underlayment is reliable, flexible and water-resistant. Since it’s readily available, this material can cost less than other underlayment options.
Non-bitumen synthetic – Non-bitumen synthetic underlayment is currently the most-preferred by roofers. This material offers better water resistance than asphalt-saturated underlayment. It’s fit for full application on the entire roof, making it a cost-effective option for homeowners.
Rubberized asphalt – Rubberized asphalt has the combined benefits of asphalt-saturated and non-bitumen synthetic underlayments. Its high percentage of asphalt and rubber polymer makes it waterproof. This underlayment option has a sticky back with a protective membrane, which creates a natural water barrier between it and the decking.
