Abstract: A ridge vent for covering an open ridge of a roof comprises an elongated panel having two opposed lateral edges; a pair of elongated sidewalls, each extending downward from one of the lateral edges; a pair of elongated floor portions, each extending outward from one of the sidewalls; a pair of elongated baffles, each extending upward from one of the floor portions, each baffle combining with one of the sidewalls and one of the floor portions to form an elongated trough along one side of the panel; and a filtering structure over each trough between the sidewall and the baffle to prevent particles and debris from collecting in the trough while allowing free flow of air.

Abstract: A ridge vent for covering an open ridge of a roof comprises an elongated panel with two opposed lateral edges; a pair of elongated sidewalls extending downward from one of the lateral edges; a pair of elongated floor portions each extending outward from one of the sidewalls, each floor portion having an underside; and a sealant on the underside of at least a part of each floor portion to improve the seal between the floor portions and the roof.
