Abstract: A laminated shingle is provided, having lighter and darker granule portions visible from the front, at different planes; the front-most or anterior lane generally having granules of lighter shading and the more rearward or posterior plane generally having darker granules. The darker granules in the more posterior plane are visible from the front of the shingle to provide visually sharp, precise delineation between zones of lighter and darker shading. The shingles may be of multi-layer construction with suitable adhesives securing the layers together. The darker granules may be visible from beneath the lower edge(s) of the anterior shingle, to provide a shadow line effect. Alternatively, or in addition thereto, the darker shingle zones from the more posterior plane may be visible through tab-separating slots of the lighter shaded anterior shingle portion.

Abstract: The variegated shingle comprises a shingle layer having front and rear surfaces the front surface including a butt portion and a headlap portion. The shingle layer contains granules on the front surface forming a plurality of horizontal striations providing gradations having color values ranging from light to dark extending between a leading edge of the butt portion and an upper portion thereof. The striations include an upper striation along the upper portion, a lower striation closer to the leading edge, and an intermediate striation between the upper and lower striations. The upper striation is darker in color value than the lower striation, whereas the intermediate striation is no darker in color value than the upper striation and no lighter in color value than the lower striation. The color values of at least one of the upper, lower, and intermediate striations vary across the granule layer.

Abstract: A method for the production of a laminated shingle wherein at least two strips of a continuously advancing sheet are coated with differently colored aggregates of granules. Present among one of the aggregates are a multitude of granules having at least one color and/or hue thereof not present among the granules of the other aggregate or aggregates. The strips are cut from the sheet and laminated one above the other so as to form at least two layers with the differently colored aggregates exposed to view. The difference in coloration creates a pleasing color contrast and accentuates the difference in elevation between the shingle layers.

Abstract: This invention is directed to a multi-layer laminated shingle, wherein each shingle layer comprises granule and bituminous coated web, with the layers laminated together and with the butt zone of the base layer disposed against a bottom surface of the tab zone of the secondary layer and with the tab zone of the base layer disposed against the bottom surface of the butt zone of the secondary layer. The shingle lends itself to having tabs spaced by voids. Because the tabs in the base layer are inverted, the base layer's butt zone is visible through voids in the tabs of the secondary layer. The method of making the shingle lends itself to complementally cutting out the tabs of two side-by-side shingles from a given line. Enhanced nailing area is provided, and stacking of shingles for packaging is facilitated.

Abstract: This invention relates to a unitary roofing shingle sheet comprising (a) an undivided cop section having an unexposable upper portion and a lower portion carrying a partially exposable horizontal band of distinguishable colors or color patterns and (b) exposable tabs in a butt bottom section depending from the lower boundary of the band in the partially exposable portion of (a); the exposable portions of said shingle being covered with weather resistant granules of distinguishable hues or patterns disposed in discrete exposable areas in the band of section (a) and on each of said tabs so as to provide a distinctive color or pattern for each tab and a contrasting color or color pattern above each tab in the adjoining exposable portion of said band of section (a).
