A molded roofing material tile that forms a five-sided rectangular box-like structure with a central support spine running on the underside of the tile from the back side to the front side, that permits virtually free drainage of sub-tile water through an elongated weep aperture running along the back side of the tile, thereby to drain water away that would otherwise deteriorate the tile and the underlayment. The tile has rabbeted sides that permit overlapping with side adjacent tiles laid in a roofing course. The tiles are fastened by conventional fasteners that run through reinforced fastener posts at the rear corners of the tile, and do not require application of special adhesive. No special alternative embodiment is required as an initial course of tile nearest the eaves of the building.

A molded roofing tile, comprising: (a) a planar panel having a face side and an under side; (b) a bottom flange angularly juxtaposed adjacent said panel; (c) a top flange angularly juxtaposed adjacent said panel, which top flange defines a single elongated drainage slot which is substantially parallel to the plane of said panel said slot elongated with respect to the length of said top flange; (d) a first side flange angularly juxtaposed adjacent said panel, which first side flange is molded so as to form an over fitting rabbet; (e) a second side flange angularly juxtaposed adjacent said panel, which first side flange is molded so as to form an under fitting rabbet; (f) a single support rib fixably attached to the under side of said panel, beginning substantially at said top flange and terminating substantially at said bottom flange; (g) said tiles being laid out on a roof by being affixed by suitable mechanical non-adhesive fastening means to a suitable underlayment means in courses, each tile\s over fitting rabbet being juxtaposed adjacent to and interlocking with an under fitting rabbet of an adjacent tile.
