Ridge Ventilator
A ridge vent is an air exhaust vent installed on the peak of a roof. When installing this vent, an air slot is first cut in the roof deck at the roof's peak.
This air slot is then covered by the ridge vent itself. They help to provide continuous, uniform exhaust ventilation at the highest portion of the attic and are designed to help resist wind-driven rain and snow, as well as insect and debris infiltration.
