A roof ridge ventilator (10) comprises a one-piece cover member (12) including a pair of flaps (14) and a hinge (16) unitary with the flaps to permit pivotal movement therebetween in order to allow use of the ventilator on roof ridges of different angles and pitches, the cover member being designed to be placed under the standard cap shingle such that the shingle extends over the cover member and down the top edges of longitudinally spaced outer support walls. A pair of vents (22) are located below the pair of cover member flaps (14), and each vent has openings (26) to permit air circulation through the roof ridge. Each vent (22) also has an upwardly projecting outer wall angled toward the cover member, and including weepage openings at the bottom of the outer wall spaced between the outer support walls to permit collected liquids to drain therethrough. The angle of the outer walls is designed to deflect air flow over the roof ridge ventilator and across the top of the cap shingle secured to the upper surface of the cover member, thereby substantially preventing foreign particle entry through the roof ridge ventilator into the building. The ventilator easily accomplishes building code requirements for air flow while providing an attractive, nearly undetectable roof ridge ventilator.
