There is disclosed a roof vent having rain control means to reduce rain water splashing into the opening in a roof vent. The baffle has a number of ridges or channels that direct rain water into a number of droplet pathways. The falling water creates a rain curtain that deflects rain water that enters into the roof vent from travelling into interior of the building. At the base of the roof vent is one or more splash deflectors that changes the angle of water impacting the base of the roof vent to limit the amount of deflected water that can enter into the opening in the roof vent. The rain curtain and one or more splash deflector may act in concert to further divert rainwater.
