The roof (200) includes a roof supporting structure (208), a radiant barrier layer (206) supported directly by the roof supporting structure (208), and a cover layer (207) laid over the radiant barrier (206). The roof (200) also includes a roof vent (210) which includes a first member (220) positioned at an aperture in the radiant barrier layer (206). The first member (220) includes a first opening (221) that permits airflow between regions above the radiant barrier layer 206 and below the radiant barrier layer (206). The roof vent also includes a second member (230) residing above the first member (220). The second member (230) includes a second opening (231) in ventilating communication with the first opening (221).
