Abstract Of The Disclosure A roof structure which has a plurality of concrete tiles arranged in overlapping rows on a roof support structure is provided with at least one roof ventilation device for venting the underside of the roof support structure. The roof ventilation device receives and integrates with a plurality of shortened tiles in an upper row to provide the roof ventilation without disturbing the appearance and continuity of the roof structure. A hollow upper portion of the roof ventilation device which is generally continuous with the tiles in the upper row forms part of a ventilation path which extends from outside the roof structure to one or more apertures in the roof support structure. At the same time, the hollow upper portion has a plurality of baffles disposed therein for preventing entry of rain water from the outside. A length of mesh mounted within an inside portion of the roof ventilation device at the back of the upper portion prevents entry of insects, vermin and debris, while foam strips mounted on the mesh seal the space above tiles in a lower row. A rear portion of the roof ventilation device, which receives the lower edges of the upper row of tiles against foam strips mounted thereon, includes clips for engaging the side edges of such tiles to hold the lower portions thereof in place. A plurality of spaced apart legs extend downwardly from the rear portion into contact with the roof support structure, and extend forwardly into contact with the upper edges of a lower row of tiles. A separate venting aperture in the roof support structure below each of the tiles in the upper row has a moisture frame mounted therein with a collar extending above the roof support structure to prevent water on the roof support structure from flowing into the aperture.
