An off-ridge roof vent includes a hood open along the sides and front and a rear flange for mounting the hood to a roof. A pair of side walls each includes lower flanges to mount to a flat roof and upper bent tabs that fit under the hood to provide a tight fit between the walls and hood. A front baffle wall extends upwardly from a flange and opening and extends under the hood and terminates in a channel to mount one edge of a screen and another channel is formed in a subtending wall from the hood to mount the other edge of the screen to prevent the entry of debris into the vented roof space. All of the flanges are connected and are in the same plane so that the vent may be attached to a flat roof.
