A roof vent construction which is comprised of an assembly including a cowl, a base, and a cowl retaining member. These elements provide a structure which provides cover for rain and discourages rain from entering the vent underneath the cowl, but nevertheless allows for suitable ventilation as needed. In one embodiment a configuration is used in which an external baffle is used which air passes before passing underneath a cowl. Once the air is passed underneath the cowl, the air then passes over one and one configuration two internal baffles before the air passes out of a pair of vent cavities defined by the base. In a second configuration, a cowl extends substantially to the leading edge of the construction. Air flows underneath the leading edge of the cowl and then passes over a large internal baffle, over a first small internal baffle, and finally over a second small internal baffle before passing through the vent cavities and out of the structure. Another invention relates to the use of two surface portions on the vent assembly, one surface portion configured to match a first course of tiles and the other surface portion configured to match a second course of tiles adjacent to said first course of tiles.
