I noticed a black spot in the kitchen ceiling yesterday. When I tried to inspect it, the drywall caved in and it was wet. The spot is about 2 inches long and 1 inch wide. The location of the spot is right below the shower drain in an upstairs bathroom.
How do I go about finding the leak and fixing it? Should I call a professional?
