Moisture/mold in attic
I have a gambrel style roof. Constantly battling mold. Live in update ny. The roof is almost vertical in the front. I doubt there is any soffitt ventilation that gets up to the attic. Small overhang in the back that is opened up. Ridge vent on top. I haven’t turned the humidifier on for a number of years and have been able to keep the mold under control. Turned humidifier on this year and went up a month ago and saw lots of mold. I sealed the electrical and vent pipe openings in the attic before blowing in insulation several years ago. Roofers suggest testing off plywood, replacing with OSB and adding edge vents to front and back. I also added a positive seal to the hatch going into the attic. Is there anyway to really prevent moisture from the house from getting into the attic? I’m hoping the added edge vents will provide enough ventilation. Also the top of the roof is very shallow and I think this frustrates the chimney effect to get air moving. Comments? Thanks.
