Answer: 
I would NOT put this over shingles. I would go down to the sheathing. When it adheres to the plywood it makes it;s best seal. Too many variables with going over shingles. There are gaps, possible nail pops, insufficient adhesion... Make sure roll roofing is ok for where yo uare installing it as well, especially if there were shingles there to begin with.

Rated 4.7 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by Easy to install, great longevity, I love this stuff This is an easy to install product. I have even installed it on my own home. Make sure you check online to see which Home D carries it because Not all do! It is so fast. Use the underlayment and offset the seams by 18" if you can I like installing it in the colder times of the year so it doesn't stick to itself but if you do it right any time is fine November 11, 2015
Rated 3.0 out of 5.0 by Not for beginners You get one shot at laying this down. It sticks to itself or cap sheet sticks to the base in a microsecond. Some practice would help September 6, 2015
Rated 5.0 out of 5.0 by Commercial Contractor As a commercial contractor, I used Firestone for the longest time, then I switched over to GAF and the installation is a simpler process. Lay down your starter course, align your cap sheet correctly, and you're good to go. Simple as that. August 27, 2015
Rated 5.0 out of 5.0 by Easy to Use! Anyone can use this product. Watch a YouTube video, come into Home Depot and don't worry about your roof for another 15 years. GAF makes a quality product here. Put down your base, and cap sheets, and you're good to go. July 31, 2015
Rated 5.0 out of 5.0 by Roofing Contractor I have a small roofing crew, about 4 guys, and we use Liberty for all of our low-slope roofs. You don't have to use a torch or any other type of open flame; it is self-adhering. Easy installation and safe installation. July 31, 2015
Rated 5.0 out of 5.0 by Liberty is a Low-Slope Gold Mine I put this on a carport a couple years back. It was easy to put on and it doesn't ever accumulate water. I would recommend this product to anyone that's dealing with a very low pitch roof. July 29, 2015
Rated 5.0 out of 5.0 by Great Product Great Product, fairly easy to work with and very durable. Be warned - The box weight is well over 100 lbs and as a result it's very tricky to carry. May 8, 2013
