Felt or Synthetic Roofing Underlayment: Which Should You Choose?

Your roofing system is more than just shingles or metal. There are a number of different layers that help protect your home from moisture damage like the roofing underlayment. Before you make a decision of the type of underlayment you want for your roof, here’s what you need to know.

Felt Roofing Underlayment

Felt is one of the oldest types of roofing underlayment in the industry and comes in two types — No.15 felt and No. 30 felt. No. 30 felt tends to be thicker, stronger, and is less prone to tearing during installation or harsh weather. This type of roofing underlayment is also more cost effective than other options.

There are some disadvantages to using felt roofing underlayment though. It isn’t good to leave it exposed for more than a few hours since it can dry out or leach oils in heat. It also tends to be more difficult to install and can tear during the installation process or high winds.

Synthetic Roofing Underlayment

If you want enhanced water-resistance and protection from the elements, synthetic roofing underlayment is the perfect option. This type of roofing underlayment is also resistant to mold growth, extremely durable, and can be installed quickly.

Synthetic roofing underlayment isn’t standardized though, so manufacturers may make their products differently, which means there will be different levels of quality and performance. Synthetic roofing underlayment also tends to be the more expensive option in comparison.
