Thus, Can you have too much venting in an attic? It’s possible to have too much exhaust ventilation, but you cannot have too much intake ventilation. If there is more intake ventilation than the attic’s square footage requires, it’s not problematic because any excess intake converts to “exhaust” on the leeward side of the house.
Additionally Will soffit vents work without a ridge vent? The question is: where is it going to get the air it’s trying to pull? Air flows from the nearest path of least resistance. If there is no soffit venting, the ridge vent has no option but to pull air from the other side of the ridge vent.
