Platinum HT Butyl Self Adhering Underlayment (Single Roll)

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

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 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.

Don’t know why this is not under every new roof !We have used it (and similar products) ever sincewe replaced our roof in the woods five years ago.This was used on a metal-roofed bunkhouse at alake property. As with three former roofs we’ve done this way, I expect it to last a long time and have few problems. Don’t roof without it!!!!

This stuff goes down nice and actually sticks on cool days unlike most other crap. We put it down on a 55 to 60deg day and it stuck great.

Good stuff, easy to apply. Very sticky.Easy to use, very adhering, tuff. Worth my cost

Great stuff to use under pvc roofing. Easy to lay over smoth plywood

Do not expect roofers to promote peel and stick underlayments. Amazing how many are not familiar with it, and those that are fewer have ever installed any.1. It's a little more money, key word LITTLE2. It's a little more work, key word LITTLE3. This type of product will have much slower deterioration vs felt productsand the roofing industry does NOT want roofs to last, PERIOD.60+ years out of this wet suit like underlayment? Stay Tuned!
