ABSTRACT:
A flat shingle style concrete roofing tile adapted to be laid over an underlayment in a series of courses on a roof and secured to the roof by mechanical fasteners and a sealant is provided. The tile has thickened edges along the front, back and sides molded to the underside of the tile, the front edge and the front portion of the side edges forming a step of reduced thickness relative to the adjacent part of the side edge which is adapted to resist a tile in an upper course from sliding down an inclined roof when engaged with the course immediately below it. The rear portion of the side edges and the back edge being shaped so as to provide an extended bearing surface along the back edge and the rear portion of the side edges of the tile when the tiles are lapped in successive courses. Complementary flanges extending from each side of the tile each form a ridge and a groove, the groove of each tile being adapted to receive and lock the ridge of an adjacent tile. The tile has weep holes molded in the bottom surface of the back edge of the tile located so as to divert the flow of water away from the mechanical fasteners, and to drain water which accumulates between the tile and the underlayment, thereby prolonging the useful life of the underlayment. In another embodiment there is provided a tile for use as the initial course of tile nearest the eaves, the tile having weep holes molded in the bottom surface of a front edge which is thicker than the remaining edges. The thick front edge also properly pitches the tiles, thus obviating the need for raising the fascia or installing a separate filler strip.
