In northern climates where snow is common, can I use window flashing tape or caulk under The Edge Vent instead of applying ice and water shield under The Edge Vent the first 5 inches on the deck?

Air Vent will not specify what materials are to be used beneath The Edge Vent in any climate. However, it is recommended that waterproofing underlayment or a similar performing product be used beneath The Edge Vent to protect the roof deck from possible moisture damage in northern climates.

NOTE: Local building code should be referenced before an alternate material is selected.
