A ridge vent comprising a pair of opposing vent parts each fabricated from a plurality of stacked, interconnected layers of a corrugated plastic sheet material and a top panel extending between and connected to the opposing vent parts, with the entire assembled ridge vent being rolled into a spiral or coil, and secured in that configuration for later installation on a roof. The assembled ridge vent is rolled into the spiral configuration from an initially planar configuration by engaging a leading end of the ridge vent and rolling the ridge vent onto a drum or mandrel to form a tight, uniform spiral. The rolled vent can then be labeled and banded or packaged. The fabrication process from bulk rolls of sheet material to packaged roof vents can be substantially continuous and automated. Roof vents of various lengths or widths can be manufactured with only minor adjustments or substitutions in the fabrication equipment. The ridge vent is installed by placing the roll on the peak of the roof with the free end of the spiral extending over the top of the spiral and oriented away from the direction of installation. The blank is unrolled to expose a portion of the ridge vent, which is fastened to the roof. This process is repeated until the desired length is installed. Foam end caps and air deflectors optionally may be installed.

[ What is claimed is:] [1.] A roof ventilator fabricated from a corrugated plastic sheet material, said corrugated plastic sheet material having a pair of generally planar plies and a generally convoluted ply defining a grain, said roof ventilator comprising:a plurality of panels formed from the corrugated plastic sheet material, said plurality of panels being generally stacked and connected to one another to form a vent section, said vent section having a longitudinal axis, said vent section being rolled in a direction generally parallel with said longitudinal axis so as to define a generally spiral configuration.
