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;
at least one asphalt layer, disposed on the mat, comprising asphalt and an asphalt filler;
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 has a total mass that is less than the minimum mass requirements of the D3462 standard and has a fire rating of at least Class C when tested according to at least one of ASTM E 108 or UL790.

2. The roofing material of claim 1 , wherein the roofing material is an asphalt shingle.

3. The roofing material of claim 1 , wherein the roofing material is roll roofing.

4. The roofing material of claim 1 , 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.

5. The roofing material of claim 1 , wherein the mat comprises one or more 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, and wool in a woven, non-woven, or solid form.

6. The roofing material of claim 5 , wherein the mat comprises fiberglass.

7. The roofing material of claim 1 , wherein the wt./100 sq. ft. of the asphalt is less than 15.00 lbs.

8. The roofing material of claim 7 , wherein the wt./100 sq. ft. of the asphalt is 9.00 lbs. or less.

9. 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.

10. The roofing material of claim 9 , wherein the exposed surface covering material comprises minerals grade 18.

11. The roofing material of claim 1 , wherein the wt./100 sq. ft. of the exposed surface covering material is less than 25.00 lbs.

12. The roofing material of claim 11 , wherein the wt./100 sq. ft. of the exposed surface covering material is 10.00 lbs. or less.

13. 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.

14. The roofing material of claim 13 , wherein the headlap surface covering material comprises minerals grade 18.

15. The roofing material of claim 1 , wherein the wt./100 sq. ft. of the headlap surface covering material is less than 25.00 lbs.

16. The roofing material of claim 15 , wherein the wt./100 sq. ft. of the headlap surface covering material is 12.00 lbs. or less.

17. The roofing material of claim 1 , wherein the roofing material further comprises a back surface covering material disposed on the back surface, wherein the back surface covering material comprises one or more of sand, coal slag, polymer film, minerals, plastic particles or film, metal particles or film, cement particles, clay particles, paints, coatings, glass, ceramics, wood, wood fiber, and composite materials.

18. The roofing material of claim 17 , wherein the back surface covering material comprises sand.

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

20. 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 UL790.
