Bulge in exterior fiberglass...
Oh, dear...this is new. Anyone know what this might be about? Water damage?

I would suggest that you clean the roof and area adjacent with diluted bleach/water solution. Don't worry if a little of that goes down the crack, it might help. Clean the cracked rood area, again, with alcohol and a rag. Fill the crack at the roof--wall joint with either Dicor or a polymer based caulk, Proflex RV is one. Don't use any garden variety latex or silicone sealant product on the repair.
