How the Roofing Underlayment Protects Your Roof

Understanding the different parts of your roofing system can help you take care of it better and help you communicate with your roofing contractor during your home improvement projects. The underlayment is one of the most important parts of your roof. In this blog post, Custom Installations, Inc., the top roofing services provider in our local area, explains the importance of roofing underlayment.

The Importance of the Underlayment

The roofing underlayment protects the deck from water damage and it also protects the wood parts of your roof safe from the chemicals in the asphalt shingles. Heat from the sun can damage asphalt shingles and cause them to melt. In addition, the underlayment makes sure that the roof deck won’t become exposed if a part of the roof gets blown off or damaged. It protects the wooden parts of your roof until we can perform necessary repairs. 

Different Types of Underlayments

• Asphalt-Saturated – This was the most common kind of underlayment until synthetic materials took its place around 15 years ago. Asphalt-saturated underlayment is still good because of its water-resistance, flexibility and availability. As an expert roofing and siding contractor, we can help you choose the best asphalt-saturated underlayment for your needs if you end up choosing this option.
• Non-Bitumen Synthetic – This is the most common type of underlayment today because it offers better water resistance than asphalt-saturated underlayment. A non-bitumen synthetic underlayment is also a cost-effective option because this material can be applied to the entire roofing system.
• Rubberized Asphalt – Rubberized asphalt combines the benefits and features of non-bitumen and asphalt-saturated underlayments. More importantly, it is fully waterproof because it has a higher asphalt and rubber polymer content.
