1. (WO2015142379) LIGHT WEIGHT MOLDED ROOF TILE WITH INTEGRATED SOLAR CAPABILITIES
Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

CLAIMS

What I claim is:

1. A roof tile comprising;

a tile body in the shape of a six-sided polyhedron, each side being mostly rectangular, said tile body constructed of polyurethane foam ; said tile body sides including a top surface, a bottom surface, a front surface, a rear surface, and first and second parallel side surfaces;

said tile body having an outer layer of a fire resistant, 100% solid aliphatic polyurea UV protective material on said top, front, parallel sides and back surface, and a portion of said bottom surface;

said tile body having a fire blocking inner layer of an intumescent mixture of a non-halo-genated phosphate affixed beneath said outer layer of fire resistant, aliphatic polyurea UV protective material and to said bottom surface to form a fire blocking barrier;

said roof tile bottom surface having a flat area configured to contact a roof substrate, said tile body bottom surface including a recessed area of a predetermined dome shape that includes poly foam adhesive receiving grooves/channels that increase adhesive contact area, and in said tile body bottom surface recessed area not having an outer layer of fire resistant 100% solid aliphatic polyurea ultra-violet material and not having a or inner layer of fire blocking material thereby exposing the foam polyurethane composition, the core foam tile body, within the dome shaped recess area of the roof tile for engagement with a standardized poly foam adhesive to be used to attach the roof tile in brick like fashion to an acceptable roof substrate.

2. The roof tile as in Claim 1, wherein: the length of said tile is approximately 3 times longer than a standard sized roof tile of 12 inches wide.

3. The roof tile as in Claim 1, including a gel coat layer

4. The roof tile as in Claim 1 including: said roof tile having a substantial top surface that includes an upper recessed area sized in length, width, and depth configured to receive a removable and upgradable solar "module" attachable to the top surface of said roof tile and having solar photovoltaic cells for generating electricity, to fit in the recessed area of the top surface of said roof tile.

5. A roof tile as in claim 1, comprising:

at least one specialized roof tile configured to include solar cell electrical junction components for regulating an array of power/electricity generating cells.

6. A light-weight roof tile usable with an array of identical tiles to cover the exterior roof substrate of a building comprising:

a roof tile body shaped to form a polyhedron constructed from a closed cell lightweight polyurethane foam in a predetermined shape that includes a top surface, a bottom surface, a front surface, a back surface, and first and second parallel side surfaces;

a foam adhesive applied to said bottom surface of said roof tile body that is useful for permanently attaching said roof tile body to an exterior roof substrate of a building;

said roof tile body bottom surface including a flat surface portion for contact with a building exterior roof substrate and a recessed area portion for receiving said foam adhesive, said roof tile bottom recessed area having a predetermined shape and size to increase the effective foam adhesive attachment area by at least 20% of the roof tile flat bottom surface area that receives foam adhesive increasing the attachment strength of said roof tile body to an exterior roof substrate;

an outer fire resistant aliphatic material layer ; and

an inner fire blocking layer made of a 100% solid intumescent mixture that includes non-halogenated phosphate attached to said outer layer fire retardant layer and said top surface, said portions of bottom surface, said front surface, said back surface and said first and second parallel side surfaces of said polyurethane foam tile body..

7. A roof tile as in claim 6, wherein:

said roof tile bottom surface recessed area is centrally located relative to the roof tile bottom surface and the roof tile front rear and side surfaces.

8. A roof tile as in claim 6, including:

said roof tile body including a fire resistant 100% solid aliphatic polyurea ultra-violet (U.V.) layer of material on said outer surface, said front and back surfaces, and said first and second side surfaces, and the flat area of said bottom surface.

9. A roof tile as in claim 6, including:

a fire blocking layer of material positioned on said roof tile body beneath said roof tile body fire resistant U.V. layer of material, said roof tile body bottom surface recessed area not having any fire resistant or fire blocking layers thereupon to enhance the attachment properties of said foam adhesive to the recessed area in said roof tile bottoms surface.

10. A roof tile as in claim 6, wherein:

said roof tile body is constructed from 31b and denser different foam components for light weight and strength and thermal insulation properties.

11. A roof tile as in claim 6, wherein:

said roof tile body is constructed from polymeric isocyanate and water-based HCFC-2 4 5 5 blown
