Roofing Underlayment
Posted on 2/7/21 at 5:13 pm

Anyone recommend a great roofing underlayment? I’m in the planning stages of getting a new roofing shingles so I want to start with a high quality underlayment to avoid future leaks. I’m a big fan of Matt Risinger and want to bring the roof into the 21st century by using the latest & greatest. Perhaps a peel & stick product vs the old style tar paper?
My house was built in 1979 and the roof is plywood with 20 years old shingles and a tar paper underlayment.
I’ve received 1 bid so far for shingles replacement and it included Owens Corning shingles & “Pro Armor Synthetic Underlayment”. Obviously the synthetic underlayment is an upgrade from tar paper but I’m thinking I want a premium product. On Matt’s YouTube channel he mentions a product called SharkSkin. Anyone have experience with a premium underlayment on a standard shingle roof?

The only reason for the underlayment is to facilitate removal of the shingles without damaging the decking.
For a new roof that will be replaced in a day, tar paper seems fine.
For a new construction, where there may be a delay of putting the shingles on, synthetic will last longer and it would be a good idea to use for a slight increase in cost.

The stick down is a mess when redoing a roof.I have not seen tar paper in use as of late.
Synthetic is used in modern times. I am having three rentals reroofed from hurricane damage and that's what we'll use. The new construction around here is also using it.

The Owens Corning synthetic is a good one. Most all are polymers and definitely what everyone is going to. They come in 10 square rolls so you have less seams and they are lighter than either #15 or #30 felt. Cost difference between them and felt is minimal. For the most part there are only 2 or 3 manufacturers around here and I’ve not seen Sharkskin.
GAF makes a good one that most distributors around here carry.

Shark Skin, was one of the brands that first pushed synthetic underlayment.
I am sure the price has come down along with a lot more brands making synthetic underlayment compared to regular common 15lb or 30lb organic or astm felt.

GAF felt buster is a good one, but there are numerous others on the market that are good. All we use now is synthetic, makes for a better roof system and when using a complete GAF, OC or other system it offers additional warranty from the manufacturer. I also would suggest using a good ice/ water in all valleys and at all eaves. This will save you headaches in the long run

Tri-Built synthetics are quality.

From what I’ve been told the felt does nothing more than protect the plywood until the shingles are nailed down. I guess I could be wrong but if you are depending on what’s under the shingles to prevent water to get to the plywood, than the shingle installation was the problem.

Just use Zip,tape the seams, and you'll have a far better product than most. Most shingle companies want an underlayment even over the ZIP, but shingle warranties are a joke anyway.
