A roof vent which may be mounted transversely across any roof ridge and or roof hip regardless of its contours or roof angles. A roof vent which may comprise of a combination pre-formed vent and shear resistant roof element, which may provide both ventilation from the interior of an attic space and provide a shear resistance value to the roof diaphragm. A roof vent element which may provide both attic ventilation and a shear value to the roof diaphragm. A roof vent element to provide openings to allow for the passage of air flow from the attic cavity to the outside atmosphere, a pre-formed one piece product made from a variety of metals and or plastics based upon installation requirements, said improved product made to be a strap which can be made to contour to either truss framing designs and or conventional roof framing designs. In one embodiment the roof vent and shear element is installed as a part of the roof wood sheathing diaphragm and then may have any number of roof ridge vent products on the market installed over it as with asphalt composition shingle systems. In another embodiment the roof vent and shear element is installed as part of the roof wood sheathing diaphragm and then may have any number of roof ridge vent products on the market installed over it as with concrete and or clay tile roofing systems, said concrete and or clay tile roofing systems which may or may not be supported by wooden and or metal batten systems and or any number of systems relating to concrete and or clay tile roofing systems. This exemplary roof vent addresses the need for providing a continuous ridge ventilation system while at the same time providing roof diaphragm nailing requirements as required by building codes. An improved product which may be made from pre-formed metal composites and or plastics based upon weather, geographic, seismic, building code requirements and or other conditions which may prevail. An improved product which can be pre-formed to match the contour of both conventional and truss framed roof structures. A roof shear vent which may comprise a pre-formed metal strap which is installed to the roof framing members along the hip and or ridge of a roof. A roof shear vent which may comprise a pre-formed plastic strap which is installed to the roof framing members along the hip and or ridge of a roof. A roof shear vent which may comprise holes, slots, or breaks to allow for air flow through the vent. This exemplary roof shear vent which may comprise of a contour which allows the proposed invention to settle down into a slot cut in the wood sheathing along the hip and or ridge of a roof and against the roof framing members to which it is attached. Said roof shear vent which may comprise a shape which may return vertically and then horizontally back on top of the wood sheathing and to which it may be fastened, said vent which may comprise a flange which runs parallel to the wood sheathing and which covers the wood sheathing, said roof vent element with said flange which may cover a roof underlayment material of different compositions or roof overlayment material of different compositions and which may provide a termination point for said underlayment or overlayments, said roof vent which may comprise a roof shear vent which may meet the requirements for roof diaphragm nailing along the hip and or ridge of a roof, a said roof vent element which may become a component of the wood roof shear diaphragm system. A roof shear vent which may comprise ventilation holes, slots and or breaks in which said openings may vary in size and spacing as needed to allow for different ventilation requirements, said vent in which the angle of the vent apex may vary depending on application.
