A finished flake for a roofing material including a metal flake substrate having an emissivity value up to approximately 0.25 and a reflectivity value up to approximately 0.95. A first coating is provided having unpigmented sodium silicate disposed on the substrate, wherein the first coating increases the emissivity value of the substrate and decreases the reflectivity value of the substrate. A second coating is provided having sodium silicate loaded with reflective pigments non-uniformly disposed about the first coating, wherein the finished flake has an emissivity value in excess of approximately 0.75 and a reflectivity value ranging from approximately 0.4 to approximately 0.5. 1. A finished flake for a roofing material , comprising:a metal flake substrate having an emissivity value up to approximately 0.25 and a reflectivity value up to approximately 0.95;a first coating comprising unpigmented sodium silicate disposed on the metal flake substrate, wherein the first coating increases the emissivity value of the substrate and decreases the reflectivity value of the substrate; anda second coating comprising sodium silicate loaded with reflective pigments non-uniformly disposed about the first coating of the metal flake substrate, wherein the finished flake has an emissivity value in excess of approximately 0.75 and a reflectivity value ranging from approximately 0.4 to approximately 0.5.2. The finished flake according to claim 1 , wherein the metal flake substrate comprises at least one of aluminum or aluminum alloy.3. The finished flake according to claim 1 , wherein the metal flake substrate is substantially flat.4. The finished flake according to claim 1 , wherein the first coating of unpigmented sodium silicate comprises at least one of water glass or a prepolymer of silicon dioxide and sodium oxide.5. The finished flake according to claim 1 , wherein the first coating is substantially uniformly disposed on the metal flake substrate.6. The finished flake ...
