Performance Test: The Best Type of Roofing Underlayment

What Is Underlayment?

Underlayment is made from either felt or a synthetic material laid between the roof shingles and the roof deck. The underlayment serves as a barrier between the shingles and the roof structure, protecting your home from water, ice, and wind. The underlayment is an essential part of your roofing system and should never be skipped.

Generally speaking, when you replace your roof, you will also replace your underlayment. Depending on the material, underlayment can last for 20 years. Even if you do not notice signs of a leak, it is a good idea to have your underlayment checked around the end of its lifespan. Your roofer will be able to tell you if the underlayment needs replacing or not.

Felt vs. Synthetic Underlayment

The two main types of underlayment are felt and synthetic. Felt is the most common, in large part because it has been around the longest. A major difference between felt and synthetic underlayments is that while felt is water-resistant, synthetic underlayments can be waterproof. However, this does not mean that synthetic is automatically better than felt.

For many climates, including Arizona’s, felt underlayment can provide adequate protection. While we do see heavy rains during monsoon season, applying a thicker felt underlayment (or multiple layers) can ensure that your roofing stays dry. Felt is also a budget-friendly material, typically costing less than synthetic underlayment.

The Benefits of Synthetic Underlayment

While felt underlayment is a good option for Arizona homeowners, synthetic underlayment is also very popular. This is because it provides a stronger moisture barrier and doesn’t weigh as much as felt underlayment. Synthetic underlayment also lasts longer than felt, sometimes up to 30 years.

Synthetic underlayment is a good choice for a variety of roofing materials, including:

  • Asphalt shingles
  • Wood shake
  • Tile roofing

How to Choose Your Roofing Underlayment

When it comes to choosing roofing underlayment, you should always speak with an experienced roofing contractor, like Lyons Roofing. Not only can we help you select the best type of underlayment for your particular situation, but we will also consider your budget and help you make the selection that will best suit your needs.

No matter which roofing underlayment you choose, keeping it well-maintained should be a priority. You can do this through annual roofing inspections and maintenance with Lyons Roofing. We will inspect your entire roofing system during your maintenance visit, including your underlayment, identifying any repair issues.

Repairing Underlayment

If there is a problem with your underlayment, you will need to have it repaired by a professional. Depending on the issue you are dealing with, you may be able to patch the existing underlayment. However, if the problem is extensive, you may need to replace all of your underlayment. If your underlayment needs to be repaired or replaced, this is also a good time to replace broken or missing shingles.
