The present invention is directed roof edge seal and barrier devices and their method of manufacture. A method of manufacturing a comb-like sealing strip for use as a roof edge seal or barrier comprises stamping or cutting an elongate strip of material along a sinuous path located between the edges of the strip and then separating the strip into two portions, each of which consists of a fixing edge corresponding to the edge of the original strip from which project a series of teeth or prongs forming a comb structure.

A ventilation system includes a building that has a soffit. A vent is coupled to the soffit and the vent is positionable between and open position and a closed position. The vent allows air to pass through the soffit when the vent is in the open position. The vent restricts a flow of the air through the soffit when the vent is in the closed position. The vent prevents objects from passing through the soffit when the vent is in the closed position. A control is coupled to the vent such that the control urges the vent between the open position and the closed position. The control is in electrical communication with an extrinsic electronic device thereby facilitating the vent to be remotely positioned between the open position and the closed position.

A roof vent for ventilating the roof of a building to the atmosphere. The roof vent includes a flange portion to lay against the roof, the flange portion having an opening to let air vent from the interior of the building (e.g. an attic). The roof vent can optionally include a collar portion extending from the flange portion and enclosing, at least in part, about a periphery of the opening and a cap dimensioned and configured to cover over the opening (including the hole in the roof) and optionally over the collar portion. The cap is configured to provide a passage (between the flange portion and the cap) through which air can pass between the atmosphere and the opening. The roof vent also includes a corrugated filter plate, e.g. partially enclosed by the cap, and interposed between the central opening and the passage, the corrugated filter plate having a pore size sufficient to permit air to pass through but inhibit the passage of snow particles, cinder particles and/or water droplets there-through.

A roof exhaust for exhausting gas from a building is provided. The roof exhaust includes: an enclosure including a base and a hollow body extending from said base, the enclosure having side sections and a front section extending between the side sections; a conduit extending within the hollow body along a central axis, the conduit having an inlet connectable to a source of gas and an outlet for exhausting the gas from the conduit; a hood extending in the front section over the outlet, the hood comprising an aperture and being configured to direct gas exiting the outlet through the aperture in a downward direction towards the base; and a baffle extending in the hood and sloped towards at least one of the side sections, thereby being configured to deflect gas exiting the aperture in a lateral direction substantially perpendicular to the downward direction.

A construction system for releasing moisture from a building is provided. The system is especially suitable for use in buildings having a hip, valley or gable roof. More specifically, the device gives the hip, valley or gable roof adequate ventilation and moisture vapor release portals so as to allow air and water vapor to properly rise through the interior of the hip, valley or gable roof and out through ridge vents without becoming trapped by rafters of the hip, valley or gable roof. The system has a first unit and a second unit, wherein the first unit allows air and water vapor to pass through passageways of the first unit up through the underside of the hip, valley or gable roof up and out through the ridge vent(s) and the second unit allows air from the exterior to pass into the roof cavity to circulate through the roof cavity and into the first unit.

A vent for a building has a cover attached to a base. The base has an aperture permitting gas to pass. A moisture directing means on an underside of the cover directs moisture move under the influence of gravity to fall outside of the aperture. The cover may include a slanted side wall portion, with the aperture positioned with its center displaced from the center of the cover toward the slanted side. The base may include a pair of moisture deflecting features along at least a portion of one of the nonslope sides to prevent moisture flowing along the base from within an area on the base covered by the cover to outside of the covered area at the nonslope sides. The base may also include a water deflecting ridge on its underside positioned between a downslope edge and the aperture to deflect water away.

A ventilation baffle for construction of a manufactured home has two or more parallel truss channels funning along a length of a sheet of material separated by a regularly spaced interval. The parallel truss channels are constructed to be placed over trusses and to be affixed to the trusses using the same fasteners used to secure the roof decking to the trusses. The regularly spaced interval may be one half or one third of an interval between trusses measured center to center. At least four gussets reinforce the two opposing sides of each truss channel, with at least two gussets along each of the opposing sides. The ventilation baffle creates an enclosed space when affixed to trusses with roof decking secured above. The enclosed area is inaccessible by a person when the manufactured home is complete.

A pre-vented soffit panel with an integrated screen to exclude wind-blown embers from entering the attic space. Vent holes are created in the soffit, and a screen is integrated therewith, in the factory or on a production line. The screen material is fire-resistant. The pre-vented soffit panel with integrated screen can then be packaged and shipped to a job or construction site, and installed instead of, or in place of, a prior-art soffit panel. The integrated soffit screen also prevents the intrusion of wind-blown snow and several types of insects. This integrated solution provides for more rapid and cost-effective job site installation without the need to perform costly retrofitting of metal vents into prior-art soffit panels.

A ventilation baffle skirt for construction of a manufactured home has two or more truss slots separated by a regularly spaced interval, as well as a plurality of truss overhangs with each of the plurality of truss overhangs connected to one of the two or more truss slots. Each of the truss overhangs are connected to a corresponding one of the two or more truss slots at a top portion. The ventilation baffle skirt may have the regularly spaced interval equal to one half or one third of a distance between trusses a roof structure in a manufactured home. The ventilation baffle skirt may be used with a ventilation baffle to retain insulation material in an enclosed space while providing an air gap for air circulation in the area beneath a roof.
