What is the Best Roofing Underlayment?

Posted on Synthetic Roofing Underlayment

With so much precipitation in Oregon, it’s important to consider the underlayment your Salem roofers are using on your home or business. There are two main types of roofing underlayment: synthetic roofing underlayment, and felt (which comes in varying thicknesses). Whichever one you pick, its primary purpose is to act as a water barrier and to help increase energy efficiency as a secondary heat and sound insulation barrier. Let’s break it down with a simple comparison:

Synthetic Roofing Underlayment

  • Is lighter and bears less load on your roof
  • More effective at preventing leakage
  • More flexible and resistant to wrinkling
  • Lasts much longer than felt paper
  • Can be safer for the environment
  • It is more expensive

Felt Roofing Underlayment

  • Thicker felt papers can be more water resistant
  • Felt is cheaper
  • It is made of asphalt, which is not the most friendly material for the environment

It is no secret, we are huge proponents of synthetic roofing underlayment. We think it is the superior product, hands down. That being said, choosing to use a standard #30 felt underlayment on your project does not mean you will be sabotaging your roof by any means. It is still a good product that has stood the test of time, but our experience has shown us that synthetics can do an even better job. If your job’s budget allows for you to choose synthetic underlayment, we believe that is the option you should choose.
