For a better look at what's going on in the ceiling cavity, take down the AC or skylight trims so you see and reach right into the cavity. Aluminum or wood trusses? I'd assume trusses worsen a condensation issue? Some TTs don't have particularly well insulated ceilings and that won't help either. A hygrometer might be a good thing to use to monitor the humidity level along with a dehumidifier.
We used a couple of the Dri-Z-Air dehumidifiers this winter and was surprised to see them full in just over 3 months of use. Next year will use 1 or 2 more and get a hygrometer. Last November, once the rainy season started, the humidity level increase caused about 1/2 the trim around the doors to warp badly enough that they had to be replaced. Doesn't take moisture very long to start damaging things.
