I looked at it on the Home Depot website, and it's listed as an adhesive. Personally I would not use it on my roof. It may react with the material and cause damage. I use Dicor self-leveling on the horizontal areas, and the regular 551 Dicor on the vertical seams. The most permanent product is Eternabond.
