ABSTRACT:
A ventilating cap for the roof includes a cover which is supported over a vent opening extending along the ridge of the roof by a first pair of coil springs supporting one side of the cap and a second pair of coil springs supporting the other side of the cap. Optional foam rubber blocks may be installed between the pairs of coils and also extend longitudinally along the roof to restrict entry of wind blown moisture from entering the vent opening. In another embodiment of the invention, nonwoven batts are retained by the springs to restrain entry of moisture into the vent opening. In still another embodiment of the invention, a deflectable baffle is moved from an inactive position laying on the roof to an active position closing off passages between the coils to wind blown moisture in response to wind velocity above a predetermined level.
