The roof vent comprises upper and lower ends and side edges within which a planar grille is disposed, and a drainage outlet at the lower end. The vent also includes means to capture precipitation (e.g. rain) entering the grille and eject the same via the drainage outlet. Ideally, the vent is formed of two half-vent portions 2; an exterior portion having a venting area 4 to permit passage of air and an interior portion including the means to capture/eject precipitate. In one embodiment the capture/eject means comprises a plurality of interior members 5 offset from corresponding exterior members such that rain passing through outer openings 12 of the venting area 4 are caught by the interior members and channelled to the drainage outlet. In another embodiment the capture/eject means comprises a cowl chamber (29, figure 17). Walls (23, figure 12) and hooks (9, figure 11) may be included to fold and clamp felt about the vent during installation. The felt may also be clamped between half-vent portions.
