Felt vs. Synthetic: Which Roofing Underlayment Should You Use?

If you are like most homeowners, you probably have no idea what roofing underlayment is. If you've decided to have a new roof installed on your home, you will also need to decide what kind of underlayment you want installed with it. Naturally, it is going to help to learn what exactly underlayment is and what options you have to help you make this decision.

What Is Roofing Underlayment?

Roofing underlayment is a layer of protection between the top of your roof and your home. It keeps out the elements and moisture that would get into your home and cause damage. Roofing underlayment will help your roof last longer and avoid mold and mildew. Underlayment also keeps the chemicals from the shingles from leaking onto your house, which would necessitate expensive repairs. There are a couple of different types of roofing underlayment, including synthetic and felt.

Synthetic Underlayment

Synthetic underlayment is suitable to use beneath any type of roof. Unlike felt underlayment, there are no restrictions to worry about. Synthetic underlayment works well in high winds and can stay strong against whatever nature throws at it. Synthetic underlayment also offers a number of installation options, including a peel-and-stick option. Synthetic underlayment also tends to be easier to install because it isn't as heavy. Since it lays flat, you will not have to worry about seeing any wrinkles, which can sometimes be a problem with felt material.

Felt Underlayment

A felt underlayment is a popular option for a lot of roofers due to the price and the durability. Roofing felt is a felt paper that is soaked in asphalt or fiberglass to give it strength. It comes in large rolls and is a thicker type of underlayment for your roof. Felt roofing costs a little less than synthetic underlayment, running at about 15 dollars for a 72-foot roll.

What Should You Consider When Choosing an Underlayment?

When you are determining the best type of roofing underlayment for your home, there are a few things you should look at. The first and most important thing to consider is building codes. The unfortunate truth is that sometimes local building codes and homeowner's associations make the decision for you. Once building codes are out of the way, you also need to consider the climate of the area you live in. Finally, you should consider the cost of each option and figure out what fits best into your budget.
