Proper Attic Ventilation: The Basics

Keep It Simple

Attic ventilation should be VERY simple. You have HOLES in the bottom of your attic (usually soffit vents) and HOLES in the top of your attic (ridge vent, wind turbines, static vents or power fans). Ideally, air comes IN the bottom and OUT the top. It’s just like a chimney in your home. If the temp is HIGHER than 10 degrees of ambient temp, then there is simply not enough ventilation in your attic. Clean the soffit vents and make sure whatever exhaust vent you have (gable ends, ridge vent, etc.) are open and able to move air through them easily. Watch the video below to learn how to easily do this:



Keep in mind that mixing exhaust vents (ie. having different exhaust methods, for example a ridge vent and fans), can be problematic because the strongest vent will dominate and the other exhaust vents will probably become INTAKE vents. This short-circuits the whole concept of air coming in the bottom and out the top. All the exhaust vents should be within a few feet of each other from the top.
