A friend recently bought a house and the unfinished (not taped and mudded) drywall is bowed down between the trusses across the whole ceiling. I looke d in the attic and there is standard %30 batt insulation between the trusse s and I don't know why the drywall is bowing down. What is the easiest/leas t expensive way to fix this? He doesn't want to tear all the existing drywa ll out if it can be helped. Thanks.

Just wanted to add that it's the ceiling in the garage only that is bowed d own and that should say R30 insulation. The drywall looks like its sagging down about 1/2"-3/4" between the trusses that are on 24" centers.
I would consider replacing it...... Once drywall is left in a position, and is warped, the warping is "memorized" into it. Similar to bending sheetrock prior to installing on a rounded corner. We wet it, and let it sag by placing it on a wall with a steep angle of resting. I was wondering if the rock was ran correctly, and like plywood, it has a grain and a direction of run. Also was ceiling board used? Ceiling board is more rigid. Also I consider a garage an un-climatized area and suspect to moisture.... Over the period of time, it may have taken on moisture and sagged. Are the nails/screws holding it up well? Usually a 2' on center ceiling is fine for sheetrock, if the rock is properly fastened, ceiling board quality or 5/8", and ran with the grain and or strength in mind. john

Thanks for the reply John. The 4'x8' sheets of drywall are in a heated garage and the house is 7 years old so I assume the drywall is original. It is installed perpendicular to the trusses and is screwed along all edges and in the field. I kinda figure d it would all have to come down but I hoped maybe a drywall guru had a mag ic trick up his sleeve.

Can you open up an opening in the drywall? Remove a light cover??
I thought if a garage is within a living space, it is to be double layered and muded on both layers. And at least 5/8" thick..
Maybe not the code there, but the exhaust is deadly, and should be sealed correctly.
The 24'x36' gable roof has 30' of ridge vent and continuous ventilated alum inum soffit in the 12" overhang so ventilation should not be a problem, but I do believe moist air somehow caused that drywall to sag. The previous ow ner used the space as a workshop and there is no air conditioning so it sta nds to reason that the high humidity in the summer would cause the heavy dr ywall to sag. Also, the drywall is not painted, just taped and mudded, so t he humidity was from both sides. Thanks for your input, looks to me like th e stuff is gonna have to come down.
