Our customer's HVAC unit drain in the attic clogged and overflowed. The ceiling insulation and sheetrock became waterlogged and broke due to the water weight and softening of the drywall. The main drain clog wasn't noticed and neither was the alternate drain. Check both regularly to make sure they are clear. If not, give Mr. Handyman a call so we can clear them for you.
We cleared the clog and repaired the ceiling with new sheetrock. We taped, bedded and textured the area and painted it to match the surrounding ceiling. We also added insulation in the attic.
