<p>A roof ridge vent comprises a one-piece, elongate body rollable into a spiral roll. The vent body has an elongate upper wall with a pair of longitudinally- extending side edges, an underside, and a plurality of bracing walls depending therefrom. The vent body further includes a pair of grillwork walls with ventilation openings extending downwardly and outwardly from the side edges of the upper wall. Still further, the vent body includes a pair of longitudinally-extending sidewalls that project from the outer edges of each of the grillwork walls and that are disposed upright with respect to the upper wall. Each of the sidewalls has a continuous, longitudinally--extending top strip and a spaced apart pair of longitudinally-extending walls depending from the top strip. The pair of walls includes a series of drainage openings which provide drainage paths through the sidewalls and which permit the sidewalls to be rolled into the spiral roll.</p> |
