Last week during a cold snap with high winds. I discovered moisture along the floor on one side of my bonus room, above the attached garage. Their was enough moisture that the baseboard molding buckled and pulled away from the wall. This occurred on the western facing wall. All other walls / floors were fine with no visible moisture.
I opened up the attic hatch to this area and saw plenty of insulation. Bats in the wall and blown in for the floor area.
I can't figure out what would be causing this, as the house is 2 months old.
