ABSTRACT:
An adjustable-pitch ridge vent having accordion-shaped pleated end plugs for covering an opening at the peak of a roof. The ridge vent has a top panel having opposed lateral edges and having opposed ends, and has a flexible midsection parallel to the opposed lateral edges. A plurality of semi-circular supports extending downwardly from the underside of the top panel suspend the top panel above the roof. Lateral sidewall portions, which downwardly depend from the lateral edges of the vent, have louvered ventilation openings for allowing air to escape out of the opening at the roof's peak and pass from under the vent. Gutters with outwardly upturned lips and with drain openings are adjacent the ventilation openings. Coacting male and female joiners, respectively at the ends of the vent, sealingly join adjacent like ridge vents to each other. The endwalls of the vent each have a flexible accordion-pleated midportion end plug formed therein, and the ratio of the total pleat length to the pleated midportion length is preferably at least 1.5. Shingles are nailed atop the vent after the vent is nailed to the roof, with the vent straddling the opening at the apex of the roof.
