The EPDM (I think it is EPDM) roof on my 2004 Outfitter TC is coming unglued from whatever is underneath it. I see several areas that are lifting up. None are raised more than 1/4" but they show up....
The adhesive has given up, it should not leak but with time will get worse. Only way to remedy it would be to pull it up and put new adhesive down if it doesn't pull up the luon as you pull it away, in that case you would need to get a new sheet of epdm and put down a new roof. It isn't that bad of a job to do but once you open the can of worms you might see rot on the roof that needs fixing.
