Light weight molded roof tile

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...

AI Technical Summary

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 isocyanate and a water-based blown component that is lightweight, has a high R-value for thermal insulation, is pre-molded into individual units, and is easy to install.

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 leak after a short service time.

Available pitched roof systems cannot hold up to category 4 hurricane winds.

Hail storms damage all roof systems often allowing major water penetration into the building and massive interior damage.

When struck, even if hard enough to crack or dent the tiles, water penetration is not immediately possible because of the characteristics of the tiles core.

Concrete and terra cotta roof tiles are subject to degradation due to the composition of the products and the effect of the elements.

This causes the tiles to become brittle and routinely fracture and break when basic maintenance is performed.

Typical Tile roof systems are highly material and labor intensive.
