Abstract
A synthetic roofing shingle or tile is provided, in which a core material is formed, of generally less expensive material, and with a skin material provided, disposed on a plurality of surfaces of the shingle or tile, with the skin material being generally of greater expense and having desirable weather-withstanding qualities.
Claims20
A synthetic roofing element of the shingle or tile type, for exterior application comprising a multi-layer structure having:
- (a) a skin including a first thermoplastic material;
- (b) a core including a second thermoplastic material;
- (c) wherein the first material is a highly weather resistant polymeric material relative to the second material;
- (d) wherein the second material is a polymeric material having filler therein and;
- (e) wherein the core is comprised of a substantially greater volume of second material than the volume of first material that comprises the skin;
- and
- (f) wherein the skin encapsulates a plurality of surfaces of the core.
A roof covering comprising a plurality of synthetic roofing elements applied to a roof, side by side, forming a plurality of courses, with roofing elements in given courses comprising underlying courses and having other courses comprising next-overlying courses partially covering the roofing elements in an underlying course, with each roofing element being of the shingle or tile type for exterior application comprising a multi-layer structure having:
- (a) a skin including a first thermoplastic material;
- (b) a core including a second thermoplastic material;
- (c) wherein the first material is a highly weather resistant polymeric material relative to the second material;
- (d) wherein the second material is a polymeric material having filler therein and;
- (e) wherein the core is comprised of a substantially greater volume of second material than the volume of first material that comprises the skin;
- (f) wherein the skin encapsulates a plurality of surfaces of the core.
A method of covering a roof comprising providing a plurality of roofing elements and applying them to a roof, side by side, in courses, and placing them such that the roofing elements in a given course comprise an underlying course, then providing another course that comprises a next-overlying course partially covering the roofing elements in the underlying course, then successively applying additional courses, such that roofing elements in each next-overlying course partially cover roofing elements in a next-underlying course, and wherein the step of providing roofing elements comprises providing synthetic roofing elements of the shingle or tile type for exterior application;
- and wherein the step of providing roofing elements also includes providing the roofing elements in the form of multi-layer structures, each structure having:
- (a) a skin including a first thermoplastic material;
- (b) a core including a second thermoplastic material;
- (c) wherein the first material is a highly weather resistant polymeric material relative to the second material;
- (d) wherein the second material is a polymeric material having filler therein and;
- (e) wherein the core is comprised of a substantially greater volume of second material than the volume of first material that comprises the skin;
- (f) wherein the skin encapsulates a plurality of surfaces of the core;
- and
- (g) wherein the skin includes at least one surface having three-dimensional relief therein, simulating a natural material, comprising any one of:
- (i) wood shake;
- (ii) tile;
- and
- (iii) slate.
