In the case of my leak was the PO that didn't read the manual. It did say in the manual specifically where to check and what products to use. They used some flexseal junk and despite my efforts took along time to get anything to stick.. eternabond, dicor or alpha. Took a wire well and patience before I could get alpha to stick. It's fixed but the damage is done.
I'm debating on fixing it or get letting it go, either way it won't be worth anything. One piece fiberglass isn't a guarantee either. My grandparents has leaked also, I don't think gpa has ever caulked a roof. Could ours been built better.. don't know.. even houses fall apart if not taken care of. Ours would be better if I had a shed for it.
