Abstract:
1. A multi-layer laminated shingle comprising: (a) an anterior shingle layer of uniform thickness and of a first width between upper and lower edges and having front and rear surfaces with at least one cutout extending into the width of the anterior shingle layer an amount terminating in an upper cutout edge; (b) a posterior shingle layer of a second width, less than the first width, and having front and rear surfaces; (c) with the anterior shingle layer having upper and lower areas on the rear surface thereof; (d) with the front surface of the posterior shingle layer being disposed against the lower area of the rear surface of the anterior shingle layer and comprising with the anterior shingle layer a double layer area, leaving the upper area of the rear surface of the anterior shingle layer not having the posterior shingle layer disposed thereagainst; (e) a bituminous adhesive having heat resistance to a predetermined temperature level disposed between said shingle layers, securing said layers together; (f) a visibly marked first fastening zone on the front surface of the anterior shingle layer, with said first fastening zone being defined by upper and lower demarcation limits on the front surface of the uniform thickness anterior shingle layer; (g) the upper demarcation limit being opposite the upper area of the rear surface of the anterior shingle layer; (h) the lower demarcation limit being opposite the lower area of the rear surface of the anterior shingle layer, and above the upper cutout edge of the anterior shingle layer; (i) whereby the first fastening zone on the anterior shingle layer has a portion of smaller width through a common bond area of both anterior and posterior shingle layers and has a portion of greater width through only the anterior shingle layer, with the portion of greater width through only the anterior shingle layer comprising a second fastening zone; and (j) whereby when the shingle is installed on a sloped roof and fastened through only the second fastening zone in the single thickness upper area of the anterior shingle layer, the thus fastened shingle and the adhesive together comprise means whereby the posterior shingle layer will remain in place, adhered behind the anterior shingle layer by the adhesive.
