TECHNOLOGY FOCUS - POLYMERS - Preferred Tile: The roof tile includes a molded outer layer of a fire resistant UV blocking material; a fire retardant layer molded beneath the fire resistant layer and above tile core body composition; and a gel coat layer. The roof tile includes: molded roof tile having a substantially flat bottom surface that rests into full contact with roof slope, where the bottom surface includes a recessed area of a predetermined shape that includes poly adhesive receiving grooves/channels that increase adhesive area by 23%, the recessed area not having a layer of fire retardant material and not having a layer of fire resistant UV blocking material thus exposing the core body composition of the roof tile for engagement with the poly adhesive used to attach the roof tile to the roof substrate. The length of the tile is approximately 3 times longer than a standard sized roof tile of 12 inches wide. The roof tile includes: the roof tile having a substantially upper surface that includes a recessed area sized in length, width, and depth to receive a solar module that includes solar photovoltaic cells for generating electricity; a removable solar module attached to the top surface of the roof tile and having solar photovoltaic cells for generating electricity, where the solar module is sized in length, width, and depth to fit in the recessed area of the top surface of the roof tile. Preferred Roof: The roof includes: a rigid thin metal support bar having a lateral cross-section that looks somewhat like the letter 'Z', where the bar has a base portion that includes apertures spaced apart to receive individual fasteners such as nails or screws for attaching the bar to the roof deck at a location adjacent the starter tiles at the bottom of the roof, and the bar includes a perpendicular wall portion joining the base portion and a top wall parallel to the base portion that includes a lip that is forced into a field tile having its base wall adjacent the perpendicular wall portion of the bar the support bar used for supporting the rows of field tiles placed above the starter tile to prevent downward vertical movement of the field tiles. The roof includes: at least one specialized roof tile connected to a predetermined number of solar 'Module' tiles electrically, the specialized tile including electrical junction components for regulating the array of power/electricity generated by solar 'Module' tiles. Each of the molded roof tiles is constructed of the material.
