Tear down old plaster ceiling?
I'm renovating a pretty ugly room. I've just torn down the ceiling tiles (no asbestos, woohoo!) and am left with a less than level, water damaged and wallpapered plaster ceiling. I'm trying to determine whether I should tear it down to the studs, reinsulate and put up drywall, or just try to put up 1/2" drywall over what you see in the picture. I expect there would be lots of shimming either way.
The source of the problem was fixed with a new roof long before we bought the house, and I don't see any signs of rot in the studs but the plaster and lathe are less than great.
What would ya'll recommend I do in this situation?
