Oct 6

It would be best to keep some critical comparisons in mind as you decide which one to put on your roof.

Felt underlayment vs. synthetic underlayment

It would be best to consider the weight, price, and other factors when choosing an underlayment for your roof. Let's compare synthetic and felt underlayment.

Which roof underlayment is heavier?

Synthetic underlayment is lighter than felt underlayment. The weight of your roof underneath payment will impact the labor price of the roof replacement. The main reason heavier products add to labor costs is that they are more expensive.

Since felt underlayment can be a heavier roofing material than synthetic, it does not have as many rolls as synthetic. You will need more felt underlayment, so it takes longer to transport it up the ladder to be installed on your roof. This won't increase your labor costs too much, but it's something to be aware of.

Which roof underlayment can you work more safely?

After your underlayment has been laid, your roofing contractor can begin to install your other roofing materials. They will have to walk on the underlayment while they do this. Synthetic underlayment has a non-skid surface, which makes it safer for workers.

Which roof underlayment has the longest life expectancy?

You expect a roof to last many years and stand up to the elements when you buy a new one. Synthetic underlayment is far more durable than felt.

Felt underlayment can be more easily ripped by high winds or during installation. Synthetic underlayment is also more stable and repels water than it absorbs. The felt can wrinkle if it is exposed to water or moisture. It is crucial to install shingles as soon as the felt underneath payment has been laid.

Synthetic underlayment is an excellent option for protecting your roof from the elements and provides additional strength.

Which roof underlayment is more expensive?

When homeowners hear that it is time to replace their roof, they first consider the cost. It's not surprising that roof replacements are expensive.

Although underlayment isn't as expensive as other roofing materials, it can add some cost. However, they come at different prices. Felt underlayment costs around $5.00 per square (100 feet), while synthetic underlayment costs around $7.00-$10.00 each square.

They are not significantly different in cost. It's up to your personal preference and budget to decide which one is best for you.

Which is better, synthetic or felt underlayment?

It would be best if you now had an idea of which roof underneath payment you prefer. Synthetic underlayment may be more expensive, but it's added durability and protection are well worth it.

However, if your budget is tight, you might consider feeling underlaid. It's essential to speak to your local roofing contractor to discuss your options for underlayment and how they might impact the price of your roof.


You now know the proper underlayment for you. Your roof's underlayment is only one part of your entire roofing system. Most homeowners think they don't have to be familiar with roofing materials. They make up a large portion of the cost of your new roof.
