We had our coop built a little over 6 years ago. It was a 10x16 shed, to which I added 5 slider windows, a divider wall so I'd have a storage area, a steel entrance door and a ridge vent for good ventilation. (By "I" I mean the builder. (and I use the term "builder" very loosely!!) This guy was recommended to me by 2 local hardware stores. But he did a really poor job. I guess he was too busy trying to convert me to pay attention to his work. The windows leak, the roof leaks, and the overhead trusses weren't adequately stabilized, the door didn't close and the one end wall bowed outward. So I had to pay another guy to come in and fix everything. I just didn't want to deal with the first guy again. Anyhow.........the roof has leaked in a couple spots since the beginning. Its very close to the ridge vent, so we figured it was that. DH has caulked all around the ridge vent almost every Fall, but sometimes it still leaks. Now the OSB board on the ceiling is getting very soft in 2 areas. Outside, the shingles look okay. Any ideas on how to approach this? We're not construction people, so we're sort of ignorant about what to do. I'd prefer not to pay a roofer to come, thinking maybe we could fix this ourselves. I know roof leaks are notoriously hard to figure out at times. Any tips/advice on how to handle this before we have holes in our ceiling? Anything I should be looking for that would give us a clue as to what's leaking? Thanks!
