ABSTRACT:
TECHNICAL FIELD
This invention relates in general to a shingle, and in particular, to a laminated roofing shingle including an overlay with cutouts and tabs and an underlay with shadow lines such that the shingle provides a three-dimensional effect with richness and depth.
BACKGROUND OF THE INVENTION
In the past, roofing shingles have had to satisfy two main functions when applied to a roof deck. The first function is to provide a durable, weatherproof covering for the roof deck. Roof shingles, whatever their form, are intended to provide a means of sheltering the structure below the shingles from precipitation and the deleterious effects of sun and wind. Roof shingles installed on the roof deck must perform these protecting functions for a reasonable period of time. The second function is to present an aesthetically pleasing architectural feature which enhances the overall appeal of the structure to which the shingles have been applied. This aesthetic function has been satisfied by providing asphalt shingles with various butt edge contours and surface treatments which operate to simulate more traditional, and in most cases more expensive, forms of roof coverings, such as thatch, wooden shakes, slates, and even tiles of various forms.
Although several attempts have been made to design a laminated shingle with a shadow look, there is a need to produce a shingle on a production scale with a high style shadow look.
SUMMARY OF THE INVENTION
This invention relates to a laminated shingle. In one embodiment, the laminated shingle comprises an overlay member and an underlay member. The overlay member has a front surface, a rear surface, an upper portion, and a lower portion. The lower portion includes one or more tabs having non-parallel vertical edges. The tabs are separated by cutouts. At least one cutout includes a pair of spaced apart non-parallel vertical edges extending from a lower boundary of the upper portion of the overlay member to a lower edge of the lower portion of the overlay member. A width of the at least one tab at the lower boundary of the upper portion of the overlay member is larger than a width of the at least one tab at the lower edge of the lower portion of the overlay member. At least one cutout also includes an upper edge extending between the pair of cutout vertical edges.
The underlay member includes a front surface attached to the rear surface of the overlay member, and includes a layer of granules on the front surface to form at least one vertically-oriented underlay shading area having two substantially vertical edges. At least one edge of the underlay shading area is substantially parallel to an edge of the tab of the overlay member. The vertically-oriented underlay shading area is darker in appearance than a portion of a remainder of the underlay member. One of the cutout vertical edges is arranged so that it is positioned between the vertical edges of the underlay shading area, thereby exposing a portion of the vertically-oriented underlay shading area.
According to this invention, there is also provided a laminated shingle including an overlay member having a front surface, a rear surface, an upper portion and a lower portion, the lower portion includes one or more tabs separated by cutouts. At least one tab includes a pair of substantially parallel upper vertical edge portions and a pair of substantially parallel lower vertical edge portions. At least one cutout includes a pair of spaced apart substantially parallel upper vertical edges and a pair of spaced apart non-parallel lower vertical edges. The combined upper vertical edges and lower vertical edges extend from a lower boundary of the upper portion of the overlay member to a lower edge of the lower portion of the overlay member. The at least one cutout also includes an upper edge extending between the pair of cutout upper vertical edge portions. An underlay member includes a front surface attached to the rear surface of the overlay member, and includes a layer of granules on the front surface to form at least one vertically-oriented underlay shading area having two substantially vertical edges. At least one edge of the underlay shading area has a contour substantially corresponding to the contour of the upper and lower edge portions of the tab of the overlay member. The vertically-oriented underlay shading area is darker in appearance than a portion of a remainder of the underlay member. One of the combined upper vertical edges and lower vertical edges of the cutout is arranged so that it is positioned between the vertical edges of the underlay shading area, thereby exposing a portion of the vertically-oriented underlay shading area.
According to the invention there is also provided a laminate shingle including an overlay member having a front surface, a rear surface, an upper portion, and a lower portion. The lower portion includes one or more tabs having non-parallel vertical edges. The tabs are separated by cutouts. At least one cutout includes a pair of spaced apart non-parallel vertical edges extending from a lower boundary of the upper portion of the overlay member to a lower edge of the lower portion of the overlay member. A width of the at least one tab at the lower boundary of the upper portion of the overlay member is smaller than a width of the at least one tab at the lower edge of the lower portion of the overlay member. A lower edge of the at least one tab has a substantially curve contour. The at least one cutout also includes an upper edge extending between the pair of cutout vertical edges. An underlay member includes a front surface attached to the rear surface of the overlay member, and includes a layer of granules on the front surface to form at least one vertically-oriented underlay shading area having two substantially vertical edges. At least a portion of a lower edge of the underlay shading area has a substantially curved contour. At least one vertical edge of the underlay shading area is substantially parallel to an edge of the tab of the overlay member. The vertically-oriented underlay shading area is preferably darker in appearance than a portion of a remainder of the underlay member. One of the cutout vertical edges is arranged so that it is positioned between the vertical edges of the underlay shading area, thereby exposing a portion of at least one vertical edge and at least a portion of the lower edge of the vertically-oriented underlay shading area.
According to the invention there is also provided a laminate shingle including an overlay member having a front surface, a rear surface, an upper portion, and a lower portion. The lower portion includes one or more tabs having non-parallel vertical edges. The tabs are separated by cutouts. At least one cutout includes a pair of spaced apart non-parallel vertical edges extending from a lower boundary of the upper portion of the overlay member to a lower edge of the lower portion of the overlay member. A width of at least one tab at the lower boundary of the upper portion of the overlay member is smaller than a width of the at least one tab at the lower edge of the lower portion of the overlay member. A lower edge of the at least one tab has a substantially curve contour. The at least one cutout also includes an upper edge extending between the pair of cutout vertical edges. An underlay member includes a front surface attached to the rear surface of the overlay member, and includes a layer of granules on the front surface to form at least one underlay shading area. At least a portion of a lower edge of the underlay shading area has a substantially curved contour. The underlay shading area is darker in appearance than a portion of a remainder of the underlay member. One of the tabs is arranged so that it covers a portion of the underlay shading area, thereby exposing a portion of the lower edge of the underlay shading area.
