Abstract:
Roof ridge vent system adapted for housing a plurality of fans in a central airflow channel positioned directly over the opening in a ridge portion of a roof for ventilating a plurality of vent chutes or attic space comprising: a hood member engaged with outer edge portions of vent members having air-passageway holes defined therein and inner edge portions preferably being hinged respectively to inner edge portions of base members so as to be adapted for installation on variously-pitched roofs, each base member also having outer edge portions defining a wall adapted for blocking wind from being blown into the vent and for causing airflow over the top of the vent to encourage airflow through the vent system. Vent member sections may be installed end-to-end to define an elongated airflow channel adapted for ventilating with or without assistance from the fans.
