         4 . The roofing and/or siding material as defined in  claim 2 , wherein said vinyl polymer includes a majority weight percent poly(methyl methacrylate). 
     
     
         5 . The roofing and/or siding material as defined in  claim 3 , wherein said vinyl polymer includes a majority weight percent poly(methyl methacrylate). 
     
     
         6 . The roofing and/or siding material as defined in  claim 1 , wherein said reinforcement material is a polyester material. 
     
     
         7 . The roofing and/or siding material as defined in  claim 1 , wherein said base sheet/membrane is a bitumen membrane or a modified bitumen membrane. 
     
     
         8 . The roofing and/or siding material as defined in  claim 1 , wherein a bottom surface of said base sheet/membrane includes a removable film sheet. 
     
     
         9 . A highly reflective composite material designed be applied to base sheet/membrane of a roofing and/or siding material, said highly reflective composite material comprising a reinforcement material and a multi-layer reflective film material, said reinforcement material at least partially embedded in a bottom surface of said multi-layer reflective film material, said top surface of said multi-layer reflective film material having a resulting reflectivity of at least about 70%, said multi-layer reflective film material including at least two layers, a first layer comprises a majority weight percent polyvinylidene fluoride and a second layer comprises a mixture of polyvinylidene fluoride and vinyl polymer. 
     
     
         10 . The highly reflective composite material as defined in  claim 9 , wherein said multi-layer reflective film material includes at least three layers, a first layer comprises a majority weight percent polyvinylidene fluoride, a second layer comprises a mixture of polyvinylidene fluoride and vinyl polymer, and a third layer comprises a mixture of polyvinylidene fluoride and vinyl polymer, said second layer including a majority weight percent polyvinylidene fluoride, said third layer including a majority weight percent vinyl polymer. 
     
     
         11 . The highly reflective composite material as defined in  claim 9 , wherein said vinyl polymer includes a majority weight percent poly(methyl methacrylate). 
     
     
         12 . The highly reflective composite material as defined in  claim 10 , wherein said vinyl polymer includes a majority weight percent poly(methyl methacrylate). 
     
     
         13 . The highly reflective composite material as defined in  claim 9 , wherein said reinforcement material is a polyester material. 
     
     
         14 . The highly reflective composite material as defined in  claim 12 , wherein said reinforcement material is a polyester material. 
     
     
         15 . The highly reflective composite material as defined in  claim 9 , wherein at least one of said layers of said multi-layer reflective film material includes a white pigment, white dye, or combinations thereof. 
     
     
         16 . The highly reflective composite material as defined in  claim 14 , wherein at least one of said layers of said multi-layer reflective film material includes a white pigment, white dye, or combinations thereof. 
     
     
         17 . A process for forming a roofing and/or siding material having a resulting reflectivity of at least about 50% comprising the steps of:
 a. providing a base sheet/membrane;   b. providing a highly reflective composite material, said highly reflective composite material including a reinforcement material and a multi-layer reflective film material; and,   c. securing said reinforcement material, said bottom surface of said multi-layer reflective film material, or combinations thereof to a top surface of said base sheet/membrane.   
     
     
         18 . The process as defined in  claim 17 , wherein said reinforcement material at least partially embedded in a bottom surface of said multi-layer reflective film material.
