Ventilation ceiling repairs

I have a office that was converted from the garage. The ceiling is a cathedral where the four sides come to a peak in the center. I have a window unit air condtioner to cool the room. At the peak of the celing, which is sheetrocked, the ceiling shows stains and is cracking and beginning to sag. The roof is new and does not apparently leak. I am wondering about the lack of ventilation between the roof and the sheetrock. There is insulation in this space. What can I doo to correct this problem so my ceiling does not fall down completely?
Thanks,

Sounds like it could be a condensation problem. What kind of insulation is behind it? Faced or unfaced, is there a poly layer over it?

I also suspect it's a condensation problem. I believe there is the single sided faced bat insulation. There is no ventilation in the roof. I am wondering if I need something like a ridge vent for a peaked roof. I am not sure if there is such a thing or how else I could provide ventilation if that is the problem.
Thanks,
