Yep. We applied Henry's expensive Silicone some years ago, after elastomeric, foam and other efforts failed, and it has worked very well.One coating of Henry’s Silicone roof coating applied properly and you will be worry free for 10 years, maybe more. Elastomeric states right on the label that it is for UV protection only, not for water proofing. After using Silicone-which admittely is 3-4 times as expensive, you will realize that elastomeric is akin to spreading skim milk on your roof. As a GC I will not allow elastomeric to be applied to any roof that I am responsible for. Good luck!
