Abstract
A method and apparatus are utilized to produce panels which simulate overlapping red clay roof tile. The panels are fire resistant, impact resistant, opaque, lightweight, and have sufficient strength to support fully the weight of an individual walking on the tile.
Claims2
A method for manufacturing a panel simulating a plurality of overlapping roof tile, comprising the steps of
- (a) manufacturing a mold including a plurality of spaced apart generally parallel rows each replicating the appearance of a plurality of overlapping stepped arcuate roof tile;
- (b) preparing a viscous polymer mixture including
- (i) from 30% to 75% by weight synthetic polymer resin,
- (ii) from 15% to 50% by weight filler,
- (iii) from 0.5% to 5.0% by weight catalyst to harden said resin,
- (iv) from 1% to 10% by weight pigment composition to color said polymer mixture;
- (c) conforming a pliable sheet of fiberglass to said parallel rows;
- (d) applying said viscous polymer mixture to said mold to cover said fiberglass sheet and conform to said parallel row to form a layer of said mixture which has generally uniform thickness, covers said fiberglass sheet, conforms to said parallel rows, and defines a series of generally parallel rows each replicating the appearance of a plurality of overlapping stepped arcuate roof tile;
- (e) hardening said layer;
- (f) removing said hardened layer from said mold.

A method for installing roofing on the roof of a building structure, including the steps of
- (a) manufacturing a panel simulating a plurality of overlapping roof tile, comprising the steps of
- (i) manufacturing a mold including a plurality of upstanding spaced apart generally parallel rows each replicating the appearance of a plurality of overlapping stepped arcuate roof tile,
- (ii) preparing a viscous polymer mixture including from 30% to 75% by weight synthetic polymer resin, from 15% to 50% by weight aluminum trihydrate filler, from 0.5% to 5.0% by weight hydrogen peroxide catalyst to harden said resin, from 1% to 10% by weight pigment-resin composition to color said polymer mixture;
- (iii) conforming a pliable sheet of fiberglass to said parallel rows;
- (iv) applying said viscous polymer mixture to said mold to cover said fiberglass sheet and conform to said parallel row to form a first panel layer of said mixture which has generally uniform thickness, covers said fiberglass sheet, conforms to said parallel rows, and defines a series of hollow arcuate generally parallel rows each replicating the appearance of a plurality of overlapping stepped arcuate roof tile;
- (v) hardening said first panel layer;
- (vi) removing-said hardened first panel layer from said mold;
- (b) using the mold and process of step (a) to produce a second panel layer having a shape and dimension equivalent to said first panel layer;
- (c) positioning said first panel layer on the roof of the building structure;
- and,
- (d) positioning said second panel layer on the roof of the building with said arcuate hollow rows of said second panel overlapping a portion of said arcuate hollow rows of said first panel layer.
