We've had rubber roofs on 2 other units we owned. And fiberglass on 2 others. There have been discussions on the roof material used by PC, how very thin it is and how it is not glued down. I agree aluminum is better, and steel even more so. When is the last time you saw a car roof rust through? Even when I grew up on the east coast, unless the paint and primer were seriously scratched, they never rusted thru. This was cars made in the 30's,40's and 50's.
Yes,rubber has issues, but so does fiberglass. I am aware of the issues and have successfully dealt with them. If a branch would pierce a rubber roof, I guarantee it would pierce my PC's original fiberglass.
Ron D,.... I can only repeat what the owner of the fiberglass shop told me, it was not due to leakage at a seam or sealed opening. I can say for sure, where the Fiberglass was split, it was dried and double covered with duct tape. So was the pierced skylight and microwave exhaust, neither leaked during the next day's rain and the patches I put on the roof were in good shape when I took it to the shop a week after the hail and after driving about 500 miles home.
