Reading Time: 3 minutes

Roof underlayment is an important part of any roof. With many different options to choose from, how do you know you’re getting the right underlayment for your roof? understanding the various offerings can be easier than you think. And once you know about the different types, you’ll be able to decide on what’s best for your roof. But first things first, what exactly is roof underlayment?

What Is Roof Underlayment

Roofing underlayment is a layer found between your roof’s decking and the roof’s covering. The roof covering could be tiles, shingles, or metal to name a few. Roof underlayment forms a very important water-proofing barrier by resisting moisture and heat.

What Underlayment Types Are There?

There are three main types of underlayment to choose from. Each of these comes with its unique strengths.

Asphalt-saturated Felt

This underlayment includes various amounts of asphalt, bitumen, and polyester in its construction. It’s commonly known as felt or tar paper. As in the name, the key water-proofing ingredient is the asphalt mixture. Felt paper is more affordable, but it is organic and will decay over time and in the case of Hot Mop, the installation can be more dangerous.

Rubberized Asphalt

These are sheets of rubber that have little asphalt content. Rubberized asphalt is a more costly option due to its high content of rubber polymers. Its main benefit is that it creates a 100% waterproof seal.

Non-bitumen Synthetic

Synthetic underlayment is constructed from hard-wearing plastics such as polypropylene or polyethylene. Synthetics display good waterproofing and are extremely resistant to tears. This makes them the most popular choice with their all-around versatility.

Factors to Consider When Choosing a Roof Underlayment

Before choosing the correct roof underlayment, there are a few factors to consider.

  • Type of Roofing System
  • The condition of your roof deck
  • The Roof Pitch
  • Underlayment Installation Method
  • The Thickness Of Materials

Pro Tip: It’s best to not negotiate these decisions alone. A reputable roofing expert will be able to advise you on the best roof underlayment for your home.
