Abstract

An improved roofing material having an upper and lower surface in which a thin layer comprising re-melted polypropylene or other suitable plastic is adhered to at least a portion of its lower surface.

Claims (25)

1. In a roofing material having a front surface, at least a portion of which is intended to be exposed to weather, and back surface facing in a direction opposite to the front surface, the improvement comprising a thin layer consisting essentially of a plastic material covering at least a portion of said back surface, said layer being at least 0.5 mils thick.
2. A roofing material according to claim 1 wherein said plastic material consists essentially of a thermoplastic material.
3. A roofing material according to claim 2 wherein said thermoplastic material consists essentially of polypropylene.
4. A roofing material according to claim 3 wherein said thin layer comprises re-melted polypropylene rolled material, pellets, flakes or fibers.
5. A roofing material according to claim 3 wherein said thin layer is between about 3 and 4 mils in thickness.
6. A roofing material according to claim 4 wherein said thin layer is between about 3 and 4 mils in thickness.
7. A roofing material according to claim 3 wherein said thin layer further comprises a pigment.
