A ventilation system for an attic or rafter space that mimics the appearance of the roofing material and thus has little effect on the appearance of the building. In one aspect primary vents are installed in the roof deck below the roof tiles, and the roof tiles are mounted to as to provide air spaces in between them and thus allow air flow from the primary vents to the outside. In another aspect a secondary vent is constructed to look like the surrounding field tiles and is installed over each primary vent. One or more vent openings in the secondary vent and an opening in the primary vent conduct air between the attic or rafter space and the outside. The secondary vent has a frame with one or more vent openings and a cap covering each opening shielding the ventilating space. Frames are formed in one piece and are made to fit each different size and type of roofing tile. The caps and the frame are ribbed for rigidity. The caps are made in one size only to minimize manufacturing and inventory complexity, thus any cap may be fitted on any frame. |
