My house is a semi-bungalow, built in 1952. The configuration of the roof is 2 gable ends with another gable end section perpendicular for a total of 3 gable ends. The upper floor of the house contains 2 bedrooms. The attic spaces are on either side of the rooms with a triangular section above each room. The side attics are accessible but the the top attics are not.
The house has no soffits and was built with a vent at the top of each gable end. A turbine has been added to one of the side attic areas, with a single static vent placed on the others.
I know the ventilation is poor because the bedrooms become ovens in the summer and freezers in the winter. Also, ice dams form in the winter.
I need to have the roof reshingled, but would like some advice in planning proper ventilation. I can’t find any info on how to provide proper intake when there are no soffits available. I am thinking that with 6 separate spaces I should provide intake and exhaust for each one. Exhaust seems easy enough but how do I provide intake air?
