The present invention provides 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. The vent has two pieces, a primary vent and a secondary vent and they may be made of aluminum, galvanized steel or copper. The primary vent is installed on a roof deck over a ventilation opening cut through the deck. The secondary vent is constructed to look like the surrounding field tiles and is installed over the 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 skeleton with one or more vent openings and a cap covering each opening shielding the ventilating space. Skeletons are formed in one piece and are made to fit each different size and type of roofing tile. The caps and the skeleton 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 skeleton.
