Abstract: Ridge vents and deck covers are disclosed that have a fibrous mesh mat and a moisture barrier. The mesh mat may be contoured to define a variety of structures and may have regions of relatively higher fiber density and regions of relatively lower fiber density. Solar cells may be exposed on the ridge vents to collect solar energy when the vents are exposed to sunlight.

Abstract: A ridge vent with powered forced air ventilation is configured to be installed along the ridge of a roof covering an elongated ridge slot on either side of the ridge. A blower is mounted in a blower opening formed at a predetermined location along the ridge vent on one side of the ridge and includes a blower housing forming an inlet within the attic and an outlet oriented to force air upwardly through the vent slot to be expelled through the ridge vent. A pair of baffles are hingedly secured to the blower housing adjacent its outlet and can be attached to a roof deck to secure the blower and help to isolate its outlet from the attic space below. An impeller is disposed in the housing and is driven by an electric motor.

Abstract: A fascia vent for a roof structure includes a fascia board for attachment along the lower ends of roof rafters that support a roof deck above an attic space. The fascia vent has an exposed outside face and an inside face at least partly exposed to the attic space. In one embodiment, a plurality of slots are formed along the inside face of the fascia board with a lower end of the slots communicating with ambience along the bottom edge of the fascia board and an upper end of the slots communicating with the attic space. In another embodiment, a plurality of spaced vent pockets are formed in the inside face and a slot is formed along the bottom edge of the fascia vent communicating with the vent pockets. In use, hot air vented from the attic is replaced by fresh air that flows through the fascia vent and into the attic space.

Abstract: A ridge ventilation system includes a plurality of ridge vent sections configured to be arranged end-to-end along the ridge of a roof covering a vent slot formed therealong. Each ridge vent section has an elongated longitudinally flexible top panel with a central portion, edge portions terminating at extreme edges of the top panel, and ventilation grids extending beneath and along the edge portions spaced from extreme edges thereof. The space between the extreme edges of the top panel and the ventilation grids forms or defines an overhang configured to receive edges of shingles in a course of shingles installed next to the vent section and to inhibit the edges of the shingles from rising up. The ridge vent sections also have depending deflectors for deflecting blowing rain and snow that might enter through the ventilation grids and filter fabric may be affixed to the bottom of the ridge vent sections to provide additional deflection of rain and snow.

In still another embodiment for installing along the longer rafter tails of wider rafters, the fascia board is wider and plunge cuts are made along the bottom edge of the fascia board to form a flow path to the vent pockets and thus to an attic space.

Abstract: A ridge vent with powered forced air ventilation includes a ridge vent that is configured to be installed along the ridge of a roof covering an elongated ridge slot on either side of a ridge beam of the roof. Hot air from the attic below escapes by convection through the ridge slot and is expelled to ambient atmosphere through the ridge vent. A blower is mounted in a blower opening formed at a predetermined location along the ridge vent on one side of the ridge beam. The blower includes a blower housing forming an inlet within the attic and an outlet oriented to force air upwardly through the vent slot to be expelled through the ridge vent. A pair of baffles are hingedly secured to the housing adjacent its outlet and can be hinged up for dropping the blower through the blower opening during installation, and then hinged down and attached to a roof deck covering the blower opening and a portion of the ridge slot on the other side of the ridge beam.

Abstract: An impeller exhaust ridge vent is provided for covering a ridge slot formed along the ridge of a roof. The ridge vent has an elongated laterally flexible center panel with edge portions along which vents are formed. Standoffs can depend from the bottom of the center panel for supporting the center panel a predetermined distance above the roof deck so that attic air can vent through the ridge slot, beneath the center panel, and exit through the vents. A base panel can be provided to cover the roof deck and form a smooth substantially sealed air duct for passage of the air. Upstanding wind baffles are disposed outboard of and spaced from the vents. One or more tangential impellers is rotatably mounted in the pace between the vents and wind baffles and can be free spinning or driven by an electric motor. Rotation of the tangential impellers creates a cross-flow fan effect that draws air forcibly from beneath the center panel and exhausts it to ambience. The attic space is thereby actively ventilated.

Abstract: There is provided a ridge ventilation system that comprises a ridge slot disposed longitudinally in a ridge of a roof and a fan disposed in the ridge slot for actively exhausting air from an attic substantially enclosed by the roof, sidewalls and ceiling into the ambient atmosphere. There is further provided a method for ventilating that comprises disposing a ridge slot longitudinally in a ridge of the roof and operating a fan disposed in the ridge slot to actively exhaust air from the attic into the ambient atmosphere. Lastly, there is provided a method for installing the ridge ventilation system that comprises constructing a ridge slot longitudinally disposed in a ridge of the roof and disposing a fan in the ridge slot to actively exhaust air from the attic into the ambient atmosphere.

Abstract: A fungus strip that release ions when precipitation flows down on the strip that are deleterious to fungus and algae. The strip is positioned on a building material. The strip has a length, width and thickness. The ions are preferably of zinc or tin. The building material can be asphaltic roofing shingles, non-asphaltic roofing, or siding.

Abstract: A soffit vent comprising a unitary bottom panel with extending side walls, one or more interior walls extending from the bottom panel, a one or more open channels created by the side walls, interior walls and bottom panel and one or more closed channels adjacent to the open channels.
