My house is a Dutch gambrel, so the roof is quite large. My second floor is really hot without ac and I wanted a realistic solution. Opening windows is not always an option because of oppressive humidity for several weeks and I don't have many windows up there. Last year old roof was striped off and new asphalt shingles were put on. Ridge vent was put on. In theory air flow happens up soffits and out of ridge vent. Solar panels sit on top of 1/2 of roof and were professionally installed with railing for ventilation, etc. Attic is unfinished and has ~12 inches of fiberglass batts and 3-4 inches of cellulose on top of that. Should I also install an attic fan? . . Could even get a solar one.
