  • Patent number: 5457920
    Abstract: A ridge type roof vent. A roof vent is provided for use on a ridge of a roof. The vent has grillee portions flexibly located longitudinally along the lateral edges. The grille portions have at their distal end a set of flexible teeth adapted to fit on shingles and down between shingles in the gaps therebetween, so as to prevent passage between the grille and the shingle of any debris, insects, or vermin. The grille portions have void defining structures therein adapted to receive therethrough a nail guide and support, which guide is suitable for locating a nail to affix the vent to a roof. The vent is manufactured in a flat configuration, and thus it is capable of being easily packed and shipped. When folded at the hinged bends by the installer, the vent provides full venting capability while protecting against passage therethrough of unwanted debris, insects, or vermin.
