A roof ridge ventilator with filtering device to be installed under a cap shingle includes a one piece cover member of an elongated shape including a pair of flaps, each flap having one upper surface over which cap shingles are secured and also having downwardly facing lower surfaces, a pair of vents respectively secured to the lower surface of the cover member flaps, each vent including at least one set of shielded louvers having openings for deflecting air flow while maintaining a minimum free area for air passage such that the air flowing therethrough is substantially reduced in velocity to limit the infiltration of foreign matter. Longitudinally spaced supports extend substantially vertically to permit nailing onto the roof such that the vent does not collapse during installation and such that the net free area remains intact. A band of fibrous material positioned inboard of the vent to further prevent foreign matter for entering the attic.
