The air can come up under the roof membrane from inside the camper. I had it happen this summer. Nothing was pulled out, I think there was only one little spot 4-5" where the sealant would've leaked. The only sign when stopped was a bunch of wrinkles in the roof. Went through a bad storm (wind, hail, tornado wanrings...) and I think that is what pulled it loose.
Camper was just past the 1 year warranty. Once it was opened up it was obvious that there was a lack of glue along the leading edge of the roof. Once you got back about 6 feet from the front there was plenty of glue and the membrane was about impossible to roll back. Apparently the original glue must be applied on bare wood so the moisture/solvent can escape through the wood. Not being in a position to re-deck part of the roof, I used contact cement to reglue it.
Did the repair in the in-laws drive way. Was 2000 mi from home, and didn't have time to deal with an rv service shop before we needed to move on. If I had been at home, probably would've tried to get something from manufacturer on a unit this new. I'm still on the fence whether I will leave it as repaired, of go for a complete reroof before next years major trip.
On a 5ver of motorhome there is no way to see the roof billowing. I was just barely able to see it in the mirror on my TT.
I have had problems with mine, and have been looking for other options. Mine is a '14. leaked right off the bat and now its ballooning in the same spot.
