Abstract

A laminated shingle is provided, having lighter and darker granule portions visible from the front, at different planes; the front-most or anterior plane 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.

Claims

1. A composite shingle For roofing or the like, comprising:

(a) an anterior shingle layer having front and rear surfaces between edges thereof, with the front surface having a layer of granules thereon comprising at least one visible zone of a first, lighter shading;

(b) a posterior shingle layer having front and rear surfaces between edges thereof;

(c) with substantial portions of the front surface of the posterior shingle layer being covered by the anterior shingle layer;

(d) with the posterior shingle layer having visible front surface portions that are uncovered by the anterior shingle layer;

(e) with the visible front surface portions of the posterior shingle layer being at a posterior plane relative to the plane of the front surface of the anterior shingle layer and having a layer of granules thereon comprising at least one zone of a second, darker shading than said first shading.

2. The shingle of claim 1, with edges of said anterior shingle layer comprising visually sharp, precise delineation between zones of lighter and darker shadings.

3. The shingle of claim 2, wherein an adhesive substance is provided between the front surface of the posterior shingle layer and the rear surface of the anterior shingle layer, in adhesive securement of said layers together.

4. The shingle or claim 3, wherein said adhesive substance is provided in the form of a plurality of strips.

5. The shingle of claim 2, wherein the shingle layers each have upper and lower edges, and wherein the visible front surface portions of the posterior shingle layer extend below the lower edges of the anterior shingle layer.

6. The shingle of claim 2, wherein the anterior shingle layer has upper and lower edges and slots extending into the layer from a lower edge thereof, and wherein the visible front surface portions of the posterior shingle layer are disposed behind, and are visible through, said slots.

7. The shingle of claim 2, with edges of said anterior shingle layer comprising visually sharp, precise delineation between zones of lighter and darker shadings;

wherein the shingle layers each have upper and lower edges, and wherein the visible front surface portions of the posterior shingle layer extend below the lower edges of the anterior shingle layer; and

wherein the anterior shingle layer has upper and lower edges and slots extending into the layer from a lower edge thereof, and wherein the visible front surface portions of the posterior shingle layer are disposed behind, and are visible through, said slots.

8. The shingle of claim 7, wherein an adhesive substance is provided between the front surface of the posterior shingle layer and the rear surface of the anterior shingle layer, in adhesive securement of said layers together.

9. The shingle of claim 2, wherein the posterior shingle layer extends behind, and is in engagement against, substantially the lower half of the rear surface of the anterior shingle layer.

10. The shingle of claim 2, wherein the posterior shingle layer extends behind, and is in engagement against, substantially the entirety of the rear surface of the anterior shingle layer.

11. The shingle of claim 1, wherein the lower end of the posterior shingle layer comprises a straight line, irrespective of any interruptions therein.
