Roof ridge ventilators include two panels joined by bendable hinges with each of the panels having an upper and lower surface. The lower surfaces of these panels include a plurality of spaced-apart, downwardly-projecting supports joined to the lower surfaces at substantially right angles and extending transversely across them. The support means on each panel have differing heights, with the first of the supports, of greatest height, being positioned near one end of the bottom surfaces, and with each successive support, behind the first, having successively smaller height than the preceding support. Each of the lower surfaces has substantially the same number of supports with substantially the same sizes and spacing to permit bending the ventilator over and attaching the ventilator to a roof ridge. The ventilator also includes air passages, such as a plurality of openings, of sufficient size and shape to facilitate overlapping these passages with a portion of the bottom surface of another of the ventilators. The ventilators are installed on a roof ridge by placing a cap shingle over the upper surface of the ventilator with the air passages left substantially uncovered by the shingle to form a first ventilator/shingle combination.
A roof ridge ventilator comprising two panels joined by bendable hinge means, each of said panels having an upper surface and a lower surface, each of said lower surfaces including a plurality of spaced-apart, downwardly-projecting support means joined to said lower surfaces at substantially right angles, and extending transversely across the widths of said lower surfaces, said support means on each panel having differing heights, with the first support means of greatest height being near one end of said bottom surfaces, and with each successive support means behind said first support means having successively smaller height than the preceding support means;
A method for attaching to a roof ridge a roof ventilator comprising two panels joined by bendable hinge means, each of said panels having an upper surface and a lower surface, each of said lower surfaces including a plurality of spaced-apart, downwardly-projecting support means joined to said lower surfaces at substantially right angles, and extending transversely across the widths of said lower surfaces, said support means on each panel having differing heights, with the first support means of greatest height being near one end of said bottom surfaces, and with each successive support means behind said first support means having successively smaller height than the preceding support means;
A roof ridge ventilator comprising two panels joined by bendable hinge means, each of said panels having an upper surface and a lower surface, each of said lower surfaces including a plurality of spaced-apart, downwardly-projecting support means joined to said lower surfaces at substantially right angles, and extending obliquely across the widths of said lower surfaces, said support means on each panel having different heights, with the first support means of greatest height being near one end of said bottom surfaces, and with each successive support means behind said first support means having successively smaller height than the preceding support means;
A roof ridge ventilator comprising two panels joined by bendable hinge means, each of said panels having an upper surface and a lower surface, each of said lower surfaces including a plurality of spaced-apart, downwardly-projecting support means joined to said lower surfaces at substantially right angles, and extending longitudinally along the lengths of said lower surfaces, each of said support means being of greatest height near one end of said bottom surface, and gradually diminishing in height along the length of each of said support means;
