Benefits of technology

[0022]It is an object of this invention to provide an improved molded roof tile made of poly foam, mineral fiber or fiberglass that includes polymeric isocyanat

Problems solved by technology

Tiles create a great weight on the building structure requiring a more sturdy construction of the building.
Installing tile is labor-intensive on roofs and requires hauling and lifting heavy loads of tile pieces and yards of cement for the setup work.
These products are only available on flat roofs because of limitations of fire resistance on pitched roofs and the surface cannot be satisfactorily finished.
Solar systems penetrate roof systems thus requiring special flashings, create additional weight on structures, require separate installation, adds no insulation, and creates potential drafting and leak points in a roof surface.
Available tile roof systems need frequent maintenance and

Embodiment Construction

[0027]Referring now to the drawings and in particular FIG. 1, a field tile 10 is shown as it would appear after molding from a polyurethane material preferably polymeric isocyanate and a water-based (HCFC-2455fa) blown component. The field tile 10 shown in FIG. 1 includes a bottom flat surface 12 and a lower recessed overlap portion 14 which is used to overlap the tile below the tile shown in FIG. 1 when a roof is done. The tile 10 includes a side recessed edge portion 16 that is used to interlock each field tile with an adjacent tile having a recessed portion 20 so that the tiles interlock in a side-by-side row fashion. The end 18 is flat. FIG. 1 shows a recessed groove 12a in the surface 12 that receives a foam adhesive (not shown) that is used to attach tile 10 to a roof surface.

[0028]FIG. 1 and FIG. 4 shows the tile back side 12 and grooved or recessed pattern 12a that looks like an asterisk that is basically a groove 12a that is molded in the bottom surface of tile 10 as shown ...

Abstract

An improved roof tile that is composed of a polymeric isocyanate and water blown component, mineral fiber or fiberglass, said roof tile being molded producing a roof tile with a high R-value thermal insulation and being very light weight. Each tile includes a flat bottom surface including a groove of a predetermined pattern that receives poly foam adhesive for attaching each tile to a roof substrate.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates generally to building exterior roof tiles and specifically to an improved building roof tile that is lightweight, durable, has a high R-value providing insulation against heat and cold and is easily installed.[0003]2. Description of the Prior Art[0004]Exterior building roofs have used different materials for protecting a building from inclement weather such as rain, solar energy, heat, cold, snow, ice, and wind damage.[0005]Typical roofs are made of plywood, tarpaper and shingles. Tiles are also used to cover the plywood and tarpaper. Tiles are made in small pieces and are often made of terra-cotta or other cementious material. Tiles create a great weight on the building structure requiring a more sturdy construction of the building. Installing tile is labor-intensive on roofs and requires hauling and lifting heavy loads of tile pieces and yards of cement for the setup work.[0006]The present inven...
