I just had a small bathroom renovated. Hurricane Irene caused leakage through the chimney flashing which is above the bathroom. The leak caused bubbling along a trail app. 2 1/2 feet along the ceiling in one line and a 4" long trail of bubbling paint down the wall. The bubbling contained water I have since punctured the bubbles alowing the water to escape. The flashing is fixed. The sheetrock is mold resistant green board. Can I just let the sheetrock dry and then patch or do I have to take it down. There is no insulation over the ceiling trail nor behind the wall as it is an inside wall.
