Abstract: A roof ridge ventilator for an open roof ridge has a one-piece molded plastic elongated body having a hinged area to facilitate bending along the open roof ridge and mounting to adjacent sloping roof surfaces in proximity to the open roof ridge. Integral underlying supporting structure supports the roof ridge ventilator above the sloping roof surfaces and includes an end wall on opposite sides of the roof ridge ventilator. A series of upwardly facing vents are provided in the vicinity of each end wall for ventilating air from beneath the roof through the open roof ridge and through the upwardly facing vents to atmosphere. An air deflector extends between each end wall and the upwardly facing vents to direct wind and wind driven water flowing upwardly along a sloping roof surface to follow a path above and over the upwardly facing vents, while also creating a negative pressure differential above the upwardly facing vents to assist in ventilating air beneath the roof.
