The vent is formed by an elongated self-supporting structure of sheet-like material having a plurality of longitudinal ribs adapted for positioning onto the top edges of the roof rafters. A plurality of longitudinal troughs are formed between the ribs and define the duct between the rafters. The ribs are on eight inch centers spacing the ribs transversely of the structure.
