Are there any concerns using Pro Flow™ Vented Drip Edge and The Edge Vent on same roof?
There are a couple concerns:
The top flange of the Pro Flow Vented Drip Edge is approximately 6.5”. The slot for The Edge Vent is supposed to be cut between 5” and 5-3/4” from the edge of the flashing. This means that the upper flange of the vented drip edge would have to be cut.
The space beneath the roof deck would need to be sufficient for the 18 square inches per linear foot of the combined intake Net Free Area.
Other than these two items, both intake vents should be under similar pressure conditions allowing them to perform as designed.
