I live in zone 4a. I have a saltbox design home which is 1 story in the front, 2 stories in the back with ridge vents. At the highest point I get wet spots on the ceiling over my bedroom—even when there hasn’t been rain for days. There are no leaks and when I had the roof replaced I was told it was moisture condensation due to having no baffles installed in the soffits. I have lots of blown insulation and they just filled the soffits up with it when the house was built.
Do you agree with this assessment?
Also, the upstairs gets really hot in the summer and I was thinking of installing a solar gable vent at the highest peak on the side of the house. Do you think this will help with the condensation?
