I have a 2008 Palomino Gazelle G210 travel trailer. It has a rubber membrane roof. On extreme left edge of the roof the rubber membrane has lifted away from the wood beneath. The rubber is still anchored tightly to the upper side wall though. It is only occurring in small areas just inward (approx 1 inch) from where roof meets the side wall. It does not appear to be torn or leaking. I wondering if there is suppose to be a little slack in the rubber to deal with expansion. Or is this the start of the membrane separating from the wood roof? What should be done if anything? It is under warranty till 10/08.
