I would cut back to the last good sheet but the insulation is really a
bitch and I don't want to screw with any more than we have to. We are
going to sub this out anyway. Ceiling drywall is not something I am
going to do. I did it once in 1976 and never again. It was "one
manning" fire-x using home made "T" stands.

Do you think it would make sense to put up greenboard?
I didn't see any indication that this was moisture related.
