US 6,381,914 B1 · Roof tiles, roof tile layout, and method of manufacture

Abstract

Complementary roof tiles for a staggered roof tile layout are provided by: (i) extruding and conveying a composite ribbon; (ii) demarcating the composite ribbon into an alternating succession of a first roof tile type and a second roof tile type by engaging the composite ribbon with an upstream cutting blade and a downstream cutting blade, such that each roof tile type is demarcated at an upstream tile edge by one of the cutting blades and at a downstream tile edge by the other of the cutting blades, and such that a selected one of the roof tile types includes a pair of cut-out portions demarcated along one of the upstream and downstream tile edges on opposite ones of the ribbon side edges; (iii) separating the succession of demarcated roof tile types into distinct roof tiles; and (v) curing the distinct roof tiles to form a set of cured roof tiles.

A roof tile comprising:

an upper surface;
a lower surface;
a top edge;
a bottom edge;
an underlocking side edge;
an overlocking side edge;
a pair of nail holes provided in said upper surface and spaced a first distance from said top edge;
a first generally rectangular cut-out portion formed along a portion of said underlocking side edge and extending through said roof tile from said upper surface to said lower surface and from said bottom edge in the direction of said top edge;
and
a second generally rectangular cut-out portion formed along a portion of said overlocking side edge and extending through said roof tile from said upper surface to said lower surface and from said bottom edge in the direction of said top edge, wherein said first cut-out portion and said second cut-out portion extend substantially the same distance from said bottom edge along said respective side edges.

A staggered roof tile layout comprising a plurality of roof tiles arranged in series of tile rows, wherein at least one of said tile rows includes an alternating succession of a first roof tile type and a second roof tile type, and wherein:

said first roof tile type comprises
an upper surface,
a lower surface,
a top edge,
a bottom edge,
an underlocking side edge, and
an overlocking side edge;
said second roof tile type comprises
an upper surface,
a lower surface,
a top edge,
a bottom edge,
an underlocking side edge,
an overlocking side edge,
a pair of nail holes provided in said upper surface and spaced a first distance from said top edge,
a first generally rectangular cut-out portion formed along a portion of said underlocking side edge and extending through said roof tile from said upper surface to said lower surface and from said bottom edge in the direction of said top edge;
and
a second generally rectangular cut-out portion formed along a portion of said overlocking side edge and extending through said roof tile from said upper surface to said lower surface and from said bottom edge in the direction of said top edge, wherein said first cut-out portion and said second cut-out portion extend substantially the same distance from said bottom edge along said respective side edges,
said underlocking side edge of said first roof tile type engages an overlocking side edge of an adjacent tile of said second roof tile type;
said overlocking side edge of said first roof tile type engages an underlocking side edge of an adjacent tile of said second roof tile type;
said underlocking side edge of said second roof tile type engages an overlocking side edge of an adjacent tile of said first roof tile type;
said overlocking side edge of said second roof tile type engages an underlocking side edge of an adjacent tile of said first roof tile type;
said first cut-out portion of said second roof tile type extends from said bottom edge of said tile of said second type as far as said bottom edge of an adjacent tile of said first type, whereby said bottom edge of said adjacent tile of said first type is substantially aligned with a top-most extent of said first cut-out formed in said tile of said second type and is substantially misaligned relative to said bottom edge of said adjacent tile of said second type;
and
said second cut-out portion of said second roof tile type extends from said bottom edge of said tile of said second type as far as said bottom edge of an adjacent tile of said first type, whereby said bottom edge of said adjacent tile of said first type is substantially aligned with a top-most extent of said second cut-out formed in said tile of said second type and is substantially misaligned relative to said bottom edge of said adjacent tile of said second type.
