I have black mold in my bedroom ceiling due to a leaky roof. The owner of the apartment replaced the roof, but says all I need to do is bleach my ceiling. The ceiling is soft, and there is obvious water damage beyond the drywall. Also, I have to spray bleach on one part of my bathroom wall because mushrooms sprouted from a crack... yes, I said mushrooms. I have been increasingly ill and firmly believe it is from this mold. What can I do?
