Abstract:
A roofing ridge ventilator for venting a roof for air passage between the interior of a roof and the outside ambient through sides of the ventilator and through ends of the ventilator; the ventilator being adapted to be installed longitudinally overlying an open ridge of a roof; the ventilator being sufficiently flexible to be arcuately bent to accommodate a variety of different roof pitches; the ventilator comprising:(a) an elongate top wall having a predetermined length and width and top and bottom surfaces;(b) a pair of outer side walls, each one integrally formed along the longitudinal length of and depending from a respective bottom surface of said top wall and at a predetermined angle with respect to said top wall, with each of said side walls including a plurality of apertures extending therethrough for air passage therethrough;(c) a pair of upturned edge members, each one integrally formed with and extending from a respective distal end of said outer side wall opposite said top wall and extending along the longitudinal length of, and at a predetermined angle with respect to, a said side wall, said upturned edge members extending toward said top wall a predetermined distance to effectively shield at least a portion of said apertures;(d) a plurality of brace members positioned at predetermined intervals along the length of said bottom surface of said top wall, for engagement with a roof surface;(e) a pair of transverse end walls, one each integrally formed along opposite ends of the ventilator, with each end wall being discontinues at a center section thereof and comprised in said center section of a plurality of tabs depending from the bottom surface of the top wall and disposed in a first transverse row, with said tabs in said first transverse row at each end wall being transversely spaced apart from each other to define first gaps for air passage therebetween when the ventilator is installed on a roof;(f) with tabs in said first row having gaps; therebetween,(g) a second transverse row of tabs at each end of the ventilator, depending from and integrally formed with the bottom surface of the top wall, with said tabs in said second transverse row being spaced apart from each other to define second gaps for air passage therebetween when the ventilator is installed on a roof;(h) with tabs in said second row being longitudinally spaced apart from the tabs in said first row to define third gaps for air passage between said first and second rows of tabs when the ventilator is installed on a roof,(i) whereby said first, second and third gaps cooperatively comprise means providing circuitous paths for air passage between the interior of a roof and the outside ambient, across ventilator end walls, when the ventilator is installed on a roof; and(j) whereby said first and second gaps permit arcuate bending of the ventilator without providing end wall resistance to arcuate bending resulting from end wall continuity.
