Is it OK to mix different types of attic exhaust vents on the same roof above a common attic?

It is not recommend mixing two types of exhaust vents on the same roof above a common attic.

Air Vent does not recommend mixing two types of exhaust vents on the same roof when it is a common attic because it could result in short-circuiting the attic ventilation system in which one of the two exhaust vents becomes intake resulting in possible weather infiltration and less than optimal attic ventilation for the entire underside of the roof deck. There are generally five groups of exhaust vents: ridge vents, wind turbines, roof louvers, gable louvers, and power vents. If any of these different groups of exhaust vents are mixed there will potentially be a short-circuiting situation either because of their location on the roof and/or how they function. Short-circuiting the ventilation system will result in areas of the attic being bypassed (skipped). The system will still be venting, but it will not be performing optimally. Furthermore, weather infiltration is a very real possibility.
