Rip cord was a help but the paper edge would often tear off and I would have to lift up the side and try to grab the center rip cord edge to continue the lay down. At that point a wrinkle would occur. You have to be very patient or you will find yourself throwing large waded pieces off the roof. I found the Owens Corning product with the two separate plastic sheets far superior but the adhesive not as good as the Grace product

It's a good product if you can lay it out flat and straight. I had a difficult time trying to lay it out without wrinkles and sticking to it self.

This is easy to install and works beautifully to make my very flat roof water tight. Great product.

Rated 4.0 out of 5.0 by DoodnOregon Spendy but inspires confidence
I used this underlayment on a low sloping roof in a windy rainy and sometimes icy climate. The sheeting was also a little rougher than I'd like. This material is almost like a thick rubber than bridged the small gaps and softened the edges. It helped a lot to have a partner to help roll it. It is VERY sticky and could turn into a mess quickly!

The backing does not release, it tears in random strips. The adhesive on the backside edges will mess up the handling. The temperature should be below freezing when applied unless you want a giant mess.

Rated 1.0 out of 5.0 by Mgoriganti Unfriendly, Designed to sell more, not help DIY home owners.
Most unfrinfdly product, designed for contractors profits, not for reasonably skillful DIY person and to sell more with a lot of wastage as one ties to use it, For what it is worth Corning product is way better, no wonder why stores promote sales of Grace not Corning.

Rated 5.0 out of 5.0 by jsa123 Good product, did the job.
Its a little work to put it down, but it adhered well and stopped the leaks. Its a little pricey, but it works.
