ABSTRACT:
A vent for a roof, said vent2includes a box4, shaped to be a somewhat vertical chimney, in order to maximize an upward hot air flow out of the vent. The box has an upper rim and the rim has sides. A translucent hatch extends beyond the rim to provide overhangs of several inches and thereby provide rain protection at the rim when the hatch is open. A hinge allows lifting the hatch at all sides of the rim, to allow a breeze from any direction to venturi air from the chimney, without creating an air-scoop that would cause a downdraft, which downdraft would counteract the upward hot air flow. Above a preset temperature, a heat-actuated lifter lifts the hatch. The lifter increases the lift distance at higher temperatures, and decreases the lift distance at lower temperatures. The lifter closes the hatch below the pre-set temperature. The translucent hatch admits light, and inside surfaces of the box transmit that light by reflection to a space below.
