Our 850 sq. foot house has three soffit vents on the west underhang, but no
soffit vents on the east underhang (nor roof vents on the east half of the
gable roof. We have two (passive) roof vents on the west half of the gable
roof.

1) Is this enough ventilation??

2) Our garage in the back has no roof ventilation (believe it or not).
Should I put in a roof vent and two soffit vents??
