A ridge vent for tile roofing includes a vent member attached to a longitudinally extending ridge member and extending over at least a portion of a longitudinally extending vent opening. The vent member includes a number of passageways that connect the vent opening to the ambient atmosphere. A layer of air permeable and moisture resistant material covers the vent member so that air from the vented space passes through the material layer. Moisture from outside the structure coming into contact with the material layer is repelled. In one embodiment, tire material layer provides a form for a sealing layer of mortar or mastic between the tile and the vent member preventing mortar from flowing into the vent opening. In another embodiment, flexible flashing material is used to provide a seali ng structure between the tile and the vent member.
