Many people don’t think about their roofing underlayment, but it’s a very important part of the roof. But what exactly is it? Cox Roofing, one of the top roofing companies in Carroll County, explains the difference between synthetic and felt roofing underlayment.
What Is Roofing Underlayment?
Picture a roof. What do you see? Probably shingles, metal, or another exterior roofing material. However, there’s another layer under this roof covering that plays a vital role in moisture damage prevention. That’s right: Roofing underlayment. You find it between the shingles and the roof sheathing (roof deck). Roofers install it right onto the roof deck for further protection from wind, snow, rain, and other elements.
The Two Main Types of Roofing Underlayment
Felt and synthetic are the two major kinds of roofing underlayment. The one you choose depends on your roofing contractor’s suggestions, your roof design, budget, and geographical location.
Pros and Cons of Felt
Felt comes in the No. 15 and No. 30 types. No. 30 is stronger and less likely to tear during installation and extreme weather. However, it is also a bit more expensive. That being said, cost is a major pro of felt. Even the No. 30 can be affordable and it is worth the money.
There are a few cons. For example, if it’s exposed for more than a few hours during installation, it might not protect against moisture as well. Similarly, shingles need to be installed onto the felt as soon as possible to prevent improper installation. Felt is also at higher risk of tearing during installation and wind.
Pros and Cons of Synthetic
Synthetic repels water, is fast to install, and tough. It stands up well under weather and other pressure. It can also be lighter and is less likely to allow mold growth.
With all these advantages comes a higher upfront cost. That being said, synthetic tends to be cost-effective in the long run because it prevents problems, including expensive problems, and offers peace of mind.
