Platinum HT-B Self-Adhering Roofing Underlayment, 41 mil, High-Temp Ice & Water Shield, 100% Butyl, Nail Sealable, UV Resistant, ASTM Certified, Lifetime Warranty (36" x 67')

Worth every penny. Easy to put down, and quality is excellent. Thanks!

Item as described. Great price, fast delivery.

Best underlayment I’ve dealt with. Not slippery when wet. Holds up to extreme weather while you wait for roofing. Sticks tenaciously to the roof deck, and itself. Used it on my personal house.

It's real sticky.

Just finally getting the roof structure done and this stuff is the icing on the cake. Goes down easy and will protect until I can get the standing seam on. Stuck no problems in the 45° weather we had today. Buy it!

I ordered two rolls but only received one in a box that was clearly sized for two. However, the shipping label only showed 40 lbs (the weight of one roll), meaning the other roll was never shipped. Also, the roll is received was NOT self-adhering. It’s a totally different product that needs to be stapled down. The sticker on the roll said it was self-adhering but the product itself was not meaning the company will confidentiality send you the wrong thing. There appears to be a quality control issue with this product and seller. The pricing and shipping were not problematic but this will be a pain to return.

These stuff is the real deal. More expensive than other roof underlayment but worth it. Just make sure you have two people when installing, otherwise you will be on that roof for hours rolling out air pockets

I just had to re roof part of my house and I used both this and another name brand underlayment from the hardward store, and this stuff is far superior. The backing comes off easily, which wasn't the case with the other brand. Highly recommended.
