  • Peace of mind
Not being content with other products that stated they were not waterproof, I specifically sought out a roofing product that was. I came across not only this product that gives me peace of mind to have as an underlayment on my roof, but also this seller on Amazon that gave me the best price I could find, and that without having to travel nearly an hour away which is what I normally have to do for such things. Glad I got it. ... show more

  • Not as advertised.
I only have to shingle part of my house so one roll should have been plenty, so when I came up short I measured every bit I had installed. THIS ROLL IS ONLY 120 FEET LONG! I gave it 3 stars because it seems like good stuff, but I feel cheated. I should have bought it at Home Depot. They apparently sent me the wrong size, not what I ordered. After checking, they gave me a rebate. This is good stuff, and I'd have given it 5 stars if I'd had enough for the job. ... show more

  • Forget about felt
I’ve put shingles down on projects ones the years and this is the best underlayment I’ve ever found. Always used felt under shingles but this so much better.well worth the extra cost. Almost impossible to tear. Good stuff🙂

  • Great Roofing Underlayment
Great underlayment. Comparable to competitors underlayment costing 25% more. We install using hammer tackers. Great tear resistance. Good footing when damp although we stay off wet roofs for safety. 4FT tall rolls make roof dry-in quicker than the old 3FT asphalt felt rolls did. Roofing is hard work, this product makes roofing just a bit easier. ... show more

  • Will hold up to the elements.
I was an old school user of “felt, tar paper” ....never again. With this stuff, it’s on and done. If a storm blows in or you can’t get the roof on for a couple of weeks....not a problem. Just make sure you use the grip type nails. I also used the Tyvek sealing tape. Peace of mind....worth every penny. ... show more
