Abstract

A roofing material is provided having an asphalt-coated mat or felt made up of or in combinations of fiberglass, polyester, nylon, cotton, cellulosic fibers or materials, polyethylene, polypropylene, co-polymers, melamine, phenolic, acrylics, polycarbonate, carbon fiber, clay, metallic in woven, non-woven, strands or sheets, styrene compounds, rubber, silk, leather, or wool in a woven, non-woven, or solid form. The surfacing materials can be made up of or in combination minerals, plastic particles or film, metal particles or film, cement particles, clay particles, paints, coatings, glass, ceramics, wood, wood fiber, or composite materials.

First claim

What is claimed is:

1. A roofing material, comprising:
a mat, comprising top and back surfaces, the top surface comprising an exposed surface and a headlap surface;
an asphalt layer, disposed on the top surface of the mat, comprising asphalt and an asphalt filler;
a polymer layer, disposed directly on the back surface of the mat;
an exposed surface covering material disposed on the exposed surface; and
a headlap surface covering material disposed on the headlap surface;
wherein the roofing material is an asphalt shingle.

2. The roofing material of claim 1 , wherein the asphalt shingle is at least one of a strip shingle, a three-tab shingle, a laminated shingle, an architectural shingle, or a hip and ridge shingle.

3. The roofing material of claim 1 , wherein the polymer layer comprises a polyethylene film.

4. The roofing material of claim 1 , wherein the exposed surface covering material comprises one or more of minerals, plastic particles or film, metal particles or film, cement particles, clay particles, paints, coatings, glass, ceramics, wood, wood fiber, and composite materials.

5. The roofing material of claim 4 , wherein the exposed surface covering material comprises grade 18 mineral granules.

6. The roofing material of claim 1 , wherein the headlap surface covering material comprises one or more of minerals, plastic particles or film, metal particles or film, cement particles, clay particles, paints, coatings, glass, ceramics, wood, wood fiber, and composite materials.

7. The roofing material of claim 6 , wherein the headlap surface covering material comprises grade 18 mineral granules.

8. The roofing material of claim 1 , further comprising a color coating disposed on top of the top surface.

9. The roofing material of claim 1 , wherein the fire rating of the roofing material is Class A when tested according to at least one of ASTM E 108 or UL 790.

10. A system, comprising:
a roof deck; and
a roofing material on the roof deck, the roofing material comprising:
a mat, comprising top and back surfaces, the top surface comprising an exposed surface and a headlap surface;
an asphalt layer, disposed on the top surface of the mat, comprising asphalt and an asphalt filler;
a polymer layer, disposed directly on the back surface of the mat;
an exposed surface covering material disposed on the exposed surface; and
a headlap surface covering material disposed on the headlap surface.

11. The system of claim 10 , wherein the roofing material is at least one of a strip shingle, a three-tab shingle, a laminated shingle, an architectural shingle, or a hip and ridge shingle.

12. The system of claim 10 , wherein the polymer layer comprises a polyethylene film.

13. The system of claim 10 , wherein the exposed surface covering material comprises one or more of minerals, plastic particles or film, metal particles or film, cement particles, clay particles, paints, coatings, glass, ceramics, wood, wood fiber, and composite materials.

14. The system of claim 10 , wherein the exposed surface covering material comprises grade 18 mineral granules.

15. The system of claim 10 , wherein the headlap surface covering material comprises one or more of minerals, plastic particles or film, metal particles or film, cement particles, clay particles, paints, coatings, glass, ceramics, wood, wood fiber, and composite materials.

16. The system of claim 10 , wherein the headlap surface covering material comprises grade 18 mineral granules.

17. The system of claim 10 , wherein the polymer layer is a bottommost layer of the roofing material and adjacent the roof deck.

18. The system of claim 10 , wherein the roofing material further comprises a color coating disposed on top of the top surface.

19. The system f claim 10 , wherein the fire rating of the roofing material is Class A when tested according to at least one of ASTM E 108 or UL 790.
