Roofing tiles have dimensions differing from conventional tiles to allow manufacture of the tiles in a substantially greater size than conventional tile sizes. The tiles may be installed more rapidly, since each piece of material must be separately installed and a single tile may cover a greater area. Additional ribs are added underneath the interior portion of each tile than with conventional tiles. The ribs are spaced appropriately such that a person walking over each tile would have the weight of a single foot distributed over one or more ribs at all times. Moreover, the rims of each tile extend substantially deeper, through the thickness, of the tile. Each tile has material removed from the main surface portion, or the actual surface opposite the weather-exposed surface, to reduce the weight therefrom. Each tile may be configured with open air channels underneath each tile up and down the entire roof. Tiles may further be installed with no batten boards or furring strips, thus providing a complete availability of drainage and ventilation underneath the tiling system.
