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.

Abstract: A siding positioner/fastener that consists of a strip 40 with a continuous length, with inserts 50 coupled to it, at spaced intervals along the length of the strip. The strips are positioned and coupled to a substrate, aligning the strips perpendicular to the channel 70 length, which is parallel to the siding length, with a strip at each interval along the siding length, and with the inserts inline and parallel across each strip interval.

Abstract: A standing seam system includes parallel, elongate panels having first and second upstanding, interconnected edges forming a standing seam. The edges include spaced-apart upstanding portions and outer end portions. The outer end portions are folded together to form a lockseam. The outer surfaces of the lockseam and upstanding portions are generally coplanar to provide a uniform appearance and effectively conceal the lockseam.
