Good underlayment
Really good stuff. Worth the additional cost if you want superior protection. Easy to work with and has plenty of marks to guide with keeping the shingles straight.

Resilient material, withstands hard soled boots, traction perfect
I've always used tar infused paper up to using this product. This Tyvek 120 provides much less weight to handle on the roof, making going up the ladder and rolling out a breeze. The printed pattern leaves no guessing as to what nail pattern to use. Didn't slip once walking on the laid out product. Provided great traction between the sheathing and backside, between the top surface and footwear. Stayed cool to the touch in bright sunlight on a warm day, leaves no residue on clothes that comes in contact while installing.

Easy install
So far, no problem. No leaks. The description is a bit misleading, stating it's 160' long. It's 250

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.

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.

We used this as the underlay for a metal roof. After the old roofing was removed, it went down very easily, cut easily and was secure to walk on, despite our roof being 5:12. It was just the peace of mind we needed to start the whole installation process.
