Abstract
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.
