A roof vent for placement over a ventilation opening in a roof, comprising a one-piece cover plate having a first end and a second end, and a support structure extending from the cover plate for supporting at least a portion of the cover plate a distance above a surface of the roof. A portion of the support structure tapers towards the second end of the cover plate so that the distance that the cover plate is supported above a surface of the roof decreases from the cover plate's first end to its second end. The support structure defines air passageways to permit air to flow to the ventilation opening. A plurality of the roof vents can be used in overlapping fashion to provide venting along a roof ridge or hip, or the roof vents can be used to provide spot venting in the roof field.
