They embedded strips of plywood into the fiberglass. These strips are screwed into the steel roof. The problem I see is that there is about 3 or 4 inches of cap outboard from the connection point. That allows the cap to flex enough to crack the caulk.
Good news is that I think it is a cosmetic issue and the caulk further in still seals the joint. The gap is not as big as it looks at the surface. They caulked at the radius and it is much tighter an inch in.
You may want to use a butyl caulk that skins over. I used polyseamseal.
