Will soffit vents work without a ridge vent?
Installing only a ridge vent and no or inadequate soffit venting is likely to result in unnecessary heat loss from the building as convection currents of rising warm air in the attic, unable to easily draw in air from outside, will “suck” warm air from the building, thus increasing unnecessary heat loss and increasing
What can I use if I don’t have soffit vents?
The most common way to add ventilation to an attic is by installing air intakes in the soffits and putting an outlet at the gable of the house. This creates a natural air flow by drawing in the air from outside, pushing it up and out through the vent at the top of the house.
