Is it okay to mix exhaust vents?
Last Updated 5 years ago

NO! You want one TYPE of exhaust vent within a common attic area. Exhaust vents pull air from the easiest intake source. The use of two or more types of exhaust vents such as Power Vents with Roof Vents, Ridge Vents with Gable Vents, or any combination of exhaust louvers can make one of these vents act as intake for the other. Intake air should come from the soffit vent area to properly ventilate the total attic area and eliminate weather infiltration.

Lomanco's 3 Must Do Steps Flyer has additional information on using more than 1 type of exhaust vent.
