I have a den that has 12inch acoustic ceiling tile that drips water sometimes when the weather is cool.I have checked and the attic above it is thoroughly insulated. The tile was installed on furring strips direct up against the fiberglass insulation,with no drywall in between the two, materials.The roof has ridge vents and the soffits,has perforated panels. There is also a 4 foot recessed fluorescent light in the center of the ceiling that looks like a week-end novice creation,that leaks cold air around it,a little. I have lived here for 10 years and have had this problem,the entire time. Two years I had the roof replaced thinking that it would solve my problem , because the ceiling was sprouting wet spots,randomly every where. What can I do about this madness?
Pay for someone to fix it. 10 years and you didn't bother to think about water damages. It's more than visual damage.
Moisture or condensation occurs when relatively warm-moist air comes in contact with a cold surface. You need to either eliminate the air leakage supplying the moist air, or do something (usually insulate) the surface to keep it's temperature warmer to prevent condensation or a combination of both.
