Abstract

A roofing material composition and a method of applying that roofing material composition using specific angles to deflect infra-red rays and provide aesthetically nice finish is disclosed. The first coat of the roofing material is light in color and the second color may be a light or a dark color. The rough surface is prepared using specific filler, resin and paint to deflect infra-red rays and reduce heating inside a building.

Claims

1. The method of making a roofing material, comprising:

making a rough surface made of a filler, resin and paint on a substrate that is a first layer for a roof top, wherein the filler is at least one of a sand, silica sand, clashed minerals and combination thereof,

spraying a first coat using a first color of a first paint on the entire rough surface at a specific angle;

spraying a second coat using a second color of a second paint in a second specific direction at a glancing angle of at least 60 degree from the roof top to the rough surface; and

applying layer of a photo-catalytic finish to the roofing material.

2. The method of claim 1, wherein the rough surface comprising of different peaks with average peak difference being at least 1 mm.

3. The method of claim 1, wherein the rough surface is being colored based on user preferences for multi-color effects.

4. The method of claim 1, wherein the application of second color producing the multi-color effects, wherein the multi-color effect comprising of change in a color tone from a first color to a second color when observation angle is changed from 0 to 90°

with respect to a normal flat surface.

5. The method of claim 1, wherein the first color is a light color.

6. The method of claim 1, wherein the second color is a dark color.

7. The method of claim 1, wherein the first coat is not transparent.

8. The method of claim 1, wherein the rough surface at normal incidence appears to be the first color.

9. The method of claim 1, wherein the roofing material reflects an infra-red radiation.

10. The method of claim 1, further comprising:

removing excess first color by positioning the rough surface in a vertical to upside-down position.

11. The method of claim 1, further comprising

removing excess second color by positioning the rough surface to a vertical to upside-down position.

12. The method of claim 1, wherein

a non-volatile weight percent which is a weight of the resin/filler or resin mixture/filler after the rough surface gets dried exceeds 70%;

and

the first paint and the second paint is applied to obtain a color toned roof with a rough surface.

13. The method of claim 1, wherein the filler has a mean diameter between 0.1 mm and 0.3 mm;

and wherein the resin and the filler, wherein weight ratio of the resin and the filler is between ⅓ and

⅔
