I have a long house with a 3 sq foot gable vent on the east end. I have two 6 ft long roof vents in the middle and I want to know if I should install another gable vent at the west end to increase airflow.
Should I add another gable vent to the attic

Best Answer
You need to consider airflow paths. Adding random vents is not always a good idea, as it can reduce flow from other parts of the system. Adding gable vents to a soffit/ridge vent system will likely reduce flow from the edges of the space.
If you have good soffit ventilation, do not add more gable vents. Instead, add ridge venting. If the soffits are solid, gable vents could be a good idea.
