Abstract
A system, method, and apparatus for constructing and installing a roofing tile having an arbitrary design of color, patterns, textures, and the like in accordance with the requirements of a user, a designer, an architect, or the like, and provides an ability to select a color scheme for a base tile, variegations within the color of the base tile, as well as accent medallions having color, textures, and the like. Moreover, a texture may be provided to improve adhesion of the accent medallions to the base tile. In alternative embodiments, no texturing is required, but may be provided simply as a design element affecting shading in varied lighting.

A method for decorating and installing a cementitious substrate, the method comprising:
- selecting a base color scheme for a plurality of substrates formed of a cementitious material;
- selecting an accent color scheme of colors distinct from the base color scheme;
- providing the plurality substrates, each having the base color scheme, a substrate width in a lateral direction, a length in a longitudinal direction orthogonal to the lateral direction, and a top surface, the top surface having an exposed portion and a covered portion;
- providing another cementitious material comprising water, pigment, cement, and aggregate proportioned to have substantially zero slump when applied on the top surface;
- applying before curing, by impact directed substantially exclusively toward and onto the exposed portion of the top surface of each substrate of the plurality of substrates, a distribution of globules of the other cementitious material deforming to form medallions as accents, colored in the accent color scheme, the distribution varying substantially randomly in lateral width along the longitudinal direction;
- the applying, further comprising forming the medallions in shape and height substantially exclusively by impact of the other cementitious material striking at least one of the top surface and other medallions previously formed on the top surface;
- curing each substrate and corresponding medallions simultaneously, leaving the medallions bonded onto the top surface and extending above the top surface a distance controlled by the impact and the proportion of water, cement, and aggregate;
- and
- installing the plurality of substrates, after curing as a roof covering with the exposed portions of some of the plurality of substrates overlapping the covered portions of others of the plurality of substrates.

A method comprising:
- molding a plurality of roofing tiles in an uncured cementitious material, each tile of the plurality of roofing tiles having a tile width extending in a lateral direction, a tile length extending in a longitudinal direction orthogonal to the lateral direction, and a top surface comprising an exposed portion and a covered portion;
- selecting an accent color scheme substantially corresponding to naturally occurring hues of biota;
- throwing by hand onto substantially exclusively the exposed portion of each tile before curing, a substantially random distribution of globules of another cementitious material having substantially zero slump and, upon impact, deforming to form medallions as accents, colored in the accent color scheme, contacting directly and substantially exclusively the exposed portion of the uncured cementitious material, the distribution varying substantially randomly in lateral width along the longitudinal direction and the medallions varying substantially randomly in mass and height along the longitudinal direction;
- curing each tile and corresponding medallions simultaneously, leaving the medallions bonded onto the top surface and extending above the top surface;
- and
- installing the plurality of roofing tiles, after curing, on a roof with the exposed portions of some of the plurality of roofing tiles overlapping the covered portions of others of the plurality of roofing tiles.

A method comprising:
- forming a tile by extruding a top surface thereof in a pre-determined, constant, cross-sectional shape, the substrate having a base color scheme, a permanently uncovered portion, a covered portion, and formed of a cementitious material;
- selecting an accent color scheme of colors distinct from the base color scheme;
- mixing another cementitious material comprising water, cement, and aggregate by selecting the amounts thereof having substantially zero slump, in order to effectively limit spreading of the cementitious material to substantially exclusively movement in response to the momentum of impact thereof at the top surface;
- hand throwing against the permanently uncovered portion, before curing, the other cementitious material, pigmented by a first color of the colors of the accent color scheme, by directing simultaneously theretoward masses of the other cementitious material randomly sized;
- forming medallions, by the masses, upon impact of the masses at the top surface;
- the forming, further comprising distributing the medallions in a substantially random distribution of size and location about a portion of the permanently uncovered portion;
- the forming, wherein each the of medallions adopts a shape and height substantially exclusively controlled by the impact thereof at one of the top surface and another medallion on the top surface;
- repeating the hand throwing and forming, by simultaneously directing masses of the other cementitious material, pigmented by a second color of the colors of the accent color scheme;
- curing together the substrate and the medallions, leaving the medallions bonded onto the top surface and extending thereabove the same shape and height adopted immediately upon impact;
- and
- installing the tile in an overlapping arrangement having the permanently uncovered portion exposed.
