This application relates to roof vents with diverters that prevent or reduce the likelihood that water or other debris can be driven through the vent by wind. For example, a roof vent can include a lower portion and an upper portion attached to the lower portion at an upslope edge, the upper portion angling away from the upslope edge to create a space therebetween. The roof vent can also include a front opening between the lower portion and the upper portion at a downslope edge of the upper portion to allow airflow into and out of the space. The roof vent can include a diverter positioned downslope of the front opening and attached to the lower portion for preventing or reducing the likelihood that water or other debris can be driven through the vent by wind.
