    摘要: A roof vent (10) comprising a one piece plastic body including a base wall (16) having transversely spaced rows (17, 18) of integral vanes extending from one surface thereof. Preferably, one (17) of each of the rows has the vanes extending at an acute angle to the axis (32) of the base wall (16) and the other row (18) has the vanes extending at an oppositely directed acute angle. Thus air is vented through sinous paths when the roof vent (10) is positioned with the vanes engaging the roof and the base wall spaced from the roof. Water and snow are prevented by the vanes from entry beneath the vent into the building.
