Sorry to hear about your roof issue. Is it possible to provide a good description of the bubble and its location on the roof. A picture along with that would do wonders as well.
The bago fiberglass sheet roof has a void along each edge which is about 6 to 8 inches wide and the length of the rig. Under there are a series of foam pieces (icebox foam), fflat pieces and curved pieces.
The sheet is stuck to the whole roof in the middle save the sides, its then tucked into the metal channel and caulked in. One is to maintain that caulk seal diligently same goes for around the windows and fixtures on the side of the rig and the roof of the rig.
Eternabond (no financial or business relation between the product manufacturer or sales locations and me) is a great product. A once and done type thing for the roof line etc. It comes in a tape that can also fix rips in the roof panel etc.
The roof should have a line drawn and no step printed on it toward the edges like they do on air planes, because without that dealer personnel and or service folks, washing operation folks would easily step on the edges thereby flexing the membrane and breaking the seal allowing air to get underneath. The seal at the front and rear cap is also important as while in motion one could get air going under there, the eternabond strip served us well there as well.
Mcguivering is the most resorted to process for fixing design, build and quality issues by customers in this industry and the industry is none too motivated to step up the quality of product design, build or service levels because as Mr. Fields said, theres....
Interestingly the same corps have high quality products across the pond in both directions! Guess those customers or laws are more stringent.. Best of Luck with your roof issue, non fiberglass roofs can be better and worse depending on various things, personally I prefered the fiberglass until I learned the design shortfalls then we switched to metal roof machine. De-lamination is the other major issue in this industry where a ply is used as a backer board for the fiberglass laminated walls.
All the best, hope you get a speedy resolution and are able to use your rig again soon.
