ABSTRACT:
This invention relates to a ridge tile which defines a ventilating gap between the outside surface of that end portion of the tile which is overlapped in the roof and the inside surface of the overlapping end portion of the adjacent ridge tile in that its end portion which is overlapped in the roof has a flat surface and the lower portions of the outside surface of its overlapped end portion define a clearance with the inside surface of the overlapping end portion of the adjacent ridge tile. It is an object of the invention to provide a ventilating ridge tile which is of the kind defined first hereinbefore and together with an adjacent ventilating ridge tile of the same kind defines a larger effective ventilating cross-sectional area whereas the external size and shape of the ventilating ridge tile are substantially preserved and the universal usability of the ventilating ridge time in a mortar bed or with unbonded joints on roof pane tiles or ridge-adjoining tiles is obstructed or reduced. This is accomplished in that the overlapped end portion of the ridge tile is provided with additional, outwardly sloping, flat surfaces between the surface at the apex of the tile and those portions which define a clearance with the adjacent ridge tile.
