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.
