ABSTRACT:
A single sheet of relatively stiff material is formed with a flat rim surrounding a raised area except along one open side or edge with the raised area having a low elevation so as to present a low profile when placed on the roof and is in air communication with an opening through the roof with the open edge providing an opening for air passage to the atmosphere and having a baffle at the open edge to prevent foreign materials and rain from entering and having tabs at the open edge for grasping the edge of a covering roof shingle. Preferably the vent is triangular in top plan so that the apex angle of the vent opposite the open edge can be easily inserted under a shingle between the nails which hold the shingle in place.
