A fascia vent for a roof structure includes a fascia board for attachment along the lower ends of roof rafters that support a roof deck above an attic space. The fascia vent has an exposed outside face and an inside face at least partly exposed to the attic space. In one embodiment, a plurality of slots are formed along the inside face of the fascia board with a lower end of the slots communicating with ambience along the bottom edge of the fascia board and an upper end of the slots communicating with the attic space. In another embodiment, a plurality of spaced vent pockets are formed in the inside face and a slot is formed along the bottom edge of the fascia vent communicating with the vent pockets. In still another embodiment for installing along the longer rafter tails of wider rafters, the fascia board is wider and plunge cuts are made along the bottom edge of the fascia board to form a flow path to the vent pockets and thus to an attic space. In use, hot air vented from the attic is replaced by fresh air that flows through the fascia vent and into the attic space.
