A ventilating device for a roof having a vent opening includes a cover for a vent opening in the roof. The cover defines vent passages for communicating the vent opening to ambient atmosphere. A moveable member mounted adjacent to the passages is moveable from an open or inactive position permitting communication through the passages to an active or closed position in which the moveable member closes the passage to restrain entry of wind driven rain and or snow into the passages. The moveable members are returned to their inactive or open position by the resiliency of the material from which the moveable members are made and/or by the force of gravity.

[ I claim:] [1.] A ventilating device for a roof having a longitudinally extending ridge member supported by transversely spaced inclined rafters, a vent opening in said roof extending longitudinally along said ridge board, said ventilating device including a cover for said vent opening, said cover extending over said ridge board and including a pair of longitudinally extending vent parts extending along said vent opening substantially parallel to said ridge member, each of said vent parts being mounted on said roof on opposite sides of said ridge member, said vent parts defining a plurality of vent passages for communicating the vent opening to ambient atmosphere, and an elongated, longitudinally extending moveable member extending along said vent parts substantially parallel to said ridge board and movable from an inactive position permitting communication through said passages to an active position closing said passages to prevent entry of wind driven moisture into said passages, said member including a pressure responsive surface responsive to atmospheric wind to move said member from said inactive position opening said passages to said active position closing said passages in response to wind in excess of predetermined ambient wind speed, said member restoring itself to the inactive position when the ambient wind speed drops below the predetermined ambient wind speed, said member being oriented with respect to said roof such that the force of gravity urges said member to the inactive position.
