A roof vent for ventilating a roof of a building via a hole in the roof to atmosphere, the roof vent comprising: a flange portion for resting on the roof, the flange portion having an opening for overlapping with the hole; a frame portion for maintaining a cap in a spaced apart relationship with the flange portion; the cap connected to the frame portion and covering over the opening; and an integrated shield mounted on the flange portion and extending transverse to the flange portion on a side of the flange portion configured for facing a peak of the roof, the integrated shield spaced apart from the frame portion by a predefined distance and for deflecting water running down the roof to either side of the roof vent.

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.

A ridge vent system is provided including a ridge vent having opposing exterior sidewalls that each define multiple fastener recesses that extend inward from the exterior sidewalls and downward from a top plate, where each recess has multiple recess slots that cooperate with adjacent sidewall slots to form contiguous vented areas along each of the opposing exterior sidewalls to provide enhanced attic ventilation and/or airflow through the ridge vent, while still providing fastener recesses that facilitate rapid and efficient application of fasteners therethrough.

A roof vent includes a continuous elongate mat composed of a mesh of randomly oriented fibers. The mat has a top surface, a bottom surface, and a first longitudinally extending side surface. A portion of the mat proximate to and forming the first longitudinally extending side surface is configured as a wind baffle. The wind baffle includes a wind deflector lip, formed from the mesh, which extends above the top surface of the mat.

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 vent is disclosed for use in ventilating attic spaces beneath a hip roof. The vent is configured to be installed along a hip of the roof overlying and covering a ventilation slot. The vent includes an elongated laterally flexible top panel from which baffle arrays depend. The baffle arrays include a plurality of curved vanes that arc away from the slot. The vanes are configured to redirect wind-blown rain and snow away from the slot and block the migration of rain and snow through the vent. Filler strips can be attached beneath the edge portions of the vent. The filler strips conform to underlying shingles when the vent is installed to fill gaps that might be formed between the vent and the shingles. A weather filter can be positioned over some of the baffle arrays to allow attic air to pass but prevent ingress of blown snowflakes and raindrops.

A ventilated solar panel system mounted on a roof of a building (1), comprising a plurality of joists (12, 112) arranged substantially normal to an upper ridge (14) of the roof, and extending from the upper ridge (14) to a lower region of the roof, and a set of rectangular solar panels (2, 13), arranged on and supported by the joists (12, 112). The system further comprises a set of electrical fans (25), each fan (25) being arranged in the lower region of the roof and being aligned with one of the joists (12, 112), wherein each fan (25) is configured to create a flow of air towards the ridge (14), and wherein each joist (12, 112), in an end facing one of the fans (25), is formed with a dividing edge (32, 132) configured to divide the flow of air into two sub-flows (26a, 26b), a first sub-flow (26a), directed to a first side of the joist (12, 112), and a second sub-flow (26b) directed to a second side of the joist (12, 112), opposite to the first side.

Ridge vents are configured to cover an open ridge of a roof and allow a flow of air to exit from the open ridge through the ridge vents. The ridge vents include a projection and a projection receiving area. When a first ridge vent is secured over a ridge opening, the projection of a second ridge vent is at least partially receivable in the projection receiving area of the first ridge vent.

Ridge vents configured to cover an open ridge of a roof and allow a flow of air to exit from the open ridge through the ridge vents are provided. The ridge vents include a center portion having a length and a plurality of grooves. Left and right portions are connected to the center portion. The center portion is configured to flex along it's length, thereby forming a ridge vent angle between the left and right portions. The formed ridge vent angle is configured to correspond with a slope between roof decks defining the open ridge.
