... has me wondering if a continuous soffit vent should NOT be installed in a soffit that is only a few feet above another roof section, like this...
The house is in climate zone 5A and faces east. The small roof section under the arrow has a shallow eave, the wall below has a southern exposure, and the area below will receive winter sun when not shaded by the chimney. Is the rising of warm air causing snow melt and ice dams above the eave a problem here? Should I forego a soffit vent in this location? There is a similar situation on the southwest corner. Of course, during the summer, the additional air flow might be useful. Is continuous venting that meets NFA minimums, but covers only three sides of this hip roof, sufficient?
