Is it OK to combine two different types of intake vents on the same roof?

It is OK to combine two different types of intake vents on the same roof because they will work together due to their location being within similar wind pressure conditions.

If the overall attic ventilation system is already balanced with exhaust vents and intake vents it should not be necessary to add more intake. However, it is OK to combine two different types of intake vents on the same roof because they will work together due to their location being within similar wind pressure conditions.
