Inside condensation & mold
1500 sq ft home in Ky. In 2008 I had old roofing (2 layers w/o box vents) stripped and replaced with Owens Corning shingles and added 8 box roof vents. When the temp dramatically drops major condensation forms on one bedroom ceiling. This year it showed up as black mold. I have never had any problem with condensation or mold before. The only thing that changed was the new roof with vents. What is causing this? I have had the roofer redo a portion of the roof, I've installed additional insulation in attic and installed a sump pump in crawl space. Nothing has helped and no one can tell me what's causing this. I have no idea what to do but something has to be done. Please help.
