NOVELTY - The system (100) has a roof deck (112) including roofing elements (114) placed on the roof deck. Wires (102) extending along a roof (110) are placed within a tube (104) having an outer surface (106) that is exposed and complements appearance of the roofing elements. The tube comprises a rigid conduit with roofing granules affixed to the outer surface of the tube. The tube is formed from a sheet of granule-covered asphalt roofing material and into a cylinder with a seam axially running along the tube. The roofing granules are matched with appearance of the roofing elements.    USE - Wiring system for use with a roof mounted electrical system e.g. photovoltaic system, windmill, evaporative cooler, light, antenna, satellite dish and audio equipment (all claimed), on a non-horizontally pitched roof of a residential/commercial building or home.    ADVANTAGE - The system provides aesthetically appropriate building elements with the photovoltaic system with more controllable and desirable aesthetics in roofing applications, while retaining sufficient efficiency in electrical power generation. The system allows solar reflectance to reduce effective temperature of the tube, thus improving efficiency of power transferred by a cable and preventing thermal failure of the material. The system allows coating composition to reflect solar radiation that penetrates an outer coating, thus improving color and solar reflectivity. The system can be made to aesthetically and mechanically integrate with wiring features at an edge of the roof or at roof penetration.    DETAILED DESCRIPTION - The roofing granules are solar reflective granules, ceramic-coated mineral core particles, natural mineral mailers, polymeric granules and synthetic granules. The tube is formed from a polymeric material or ceramic material. An INDEPENDENT CLAIM is also included for a method for constructing a wiring system.
