A method of reducing humping of a laminated roofing shingle when the shingle is stacked with others of the shingle involves shingles that include a longitudinal central area having an overlay laminated with an underlay. The method involves providing a depression in the shingle that extends through at least a portion of the central area. In another embodiment, the invention is a method of reducing humping of a laminated roofing shingle including an overlay, an underlay, and an adhesive between the overlay and the underlay in an area of the shingle. The method involves providing a depression in the shingle that extends through at least a portion of the adhesive area. In a further embodiment, the invention is a method of reducing humping of a roofing shingle having a sealant in an area of the shingle. The method involves providing a depression in the shingle that extends through at least a portion of the sealant area.
A method of reducing humping of a laminated roofing shingle when the shingle is stacked with others of the shingle, each laminated roofing shingle including a shingle overlay having a plurality of spaced apart tabs defining cutouts therebetween, and a generally uniform thickness, each cutout having an inner end, and a shingle underlay having a generally uniform thickness, and an inner end, the method comprising:
A method of reducing humping of a laminated roofing shingle when the shingle is stacked with others of the shingle, each laminated roofing shingle including a shingle overlay having a plurality of spaced apart tabs defining cutouts therebetween, a generally uniform thickness, and a longitudinal central area at an inner end of each cutout, and a shingle underlay having a generally uniform thickness, and a longitudinal central area at an inner end of the underlay, wherein the inner end of each cutout of the shingle overlay and the inner end of the shingle underlay further define a longitudinal central area of the laminated roofing shingle, the method comprising:
A method of reducing humping of a roofing shingle having a sealant in an area of the shingle, the method comprising providing a depression in the shingle that extends through at least a portion of the sealant area, the shingle including an asphalt coating, and wherein the depression is provided by a pressing step when the asphalt coating is at a temperature within the range of from, about 130° F. (54° C.) to about 325° F. (163° C.).
