Big OOPS today as we took a tight turn in our own driveway a bit too hard and skimmed a large oak tree branch with our roof. Now we are sporting an 18 inch dent in the rolled side of the roof and the rubber membrane is now shot. Since we are looking at a new roof membrand we figured we might as well "upgrade" to a Rhino Lined roof. Has anyone done this and, if so, how did the install go and are you happy with the result? Thanks!
