Keep people and pets out of the affected area and arrange urgent professional assessment. Water-damaged ceilings can fall; the fact that dripping has stopped does not establish that the ceiling is stable. Do not stand beneath it to poke, cut or prop it up. If you hear shifting or cracking noises or see movement, leave the area and contact emergency authorities. Once it is safe, the appropriate trades can address the leak, concealed damage, drying and repairs.
