A ridge vent for tile roofs. The vent includes first and second sub-flashing portions for spanning air gaps provided between the upper reaches of a roof deck and below a centrally located ridge beam. A plurality of ventilation apertures are provided in each of the sub-flashing portions. A top cap flashing is provided for attachment above the ridge beam. Included in the top cap flashing are a plurality of ventilation apertures defined by edge wall portions. A tile roof is provided, of the flat, low profile undulating, or of the S-tile (undulating) type. Tiles are provided in rows up to the edge of the sub-flashing. The gap between the top of the tiles and the bottom of the top cap flashing is preferably provided with a weathertight seal. Ridge cap tiles are provided in conventional stacked fashion running along above the top cap flashing. As a result, a generally triangular ventilation gap is provided along and below the lateral edges of the ridge cap tile, which allows air to enter and leave the attic space below the tile roof, while providing high resistance to wind blown water.
