First claim

What is claimed is:

1. A method of reducing humping of a bundle of stacked laminated roofing shingles, each laminated roofing shingle having an overlay sheet laminated with an underlay sheet, the overlay sheet having a tab portion with cutouts normally exposed on a roof and a headlap portion normally covered-up on a roof, the headlap portion having a lower zone adjacent the tab portion and an upper zone adjacent the lower zone, the method comprising:
providing a groove in the lower zone having substantially no granules adhered thereto;
providing a reinforcement member in the groove;
stacking the shingles such that every other of the shingles is at least one of inverted and turned 180 degrees relative to an adjacent one of the shingles, thereby defining a bundle of stacked laminated roofing shingles,
wherein the bundle defines a central area that substantially encompasses the lower zones and wherein the laminated roofing shingles are double-layered, and
wherein the lack of granules in the grooves of the lower zones of the stacked shingles results in the central area of the bundle having a height substantially identical to a height of a remainder of the bundle outside the central area; and
wherein the lack of granules in the grooves of the lower zones of the stacked shingles results in the stacked shingles weighing less than an otherwise identical stack of roofing shingles having no reinforcement members.

2. The method according to claim 1 , wherein the reinforcement member defines a nail zone.

3. The method according to claim 1 , wherein the reinforcement members of the laminated roofing shingles have substantially no granules adhered thereto.

4. A method of reducing humping of a bundle of stacked laminated roofing shingles, each laminated roofing shingle having an overlay sheet laminated with an underlay sheet, the overlay sheet having a tab portion with cutouts normally exposed on a roof and a headlap portion normally covered-up on a roof, the headlap portion having a lower zone adjacent the tab portion and an upper zone adjacent the lower zone, the method comprising:
providing a groove in the lower zone;
providing a reinforcement member in the groove, wherein the reinforcement members of the laminated roofing shingles have substantially no granules adhered thereto;
stacking the shingles such that every other of the shingles is at least one of inverted and turned 180 degrees relative to an adjacent one of the shingles, thereby defining a bundle of stacked laminated roofing shingles,
wherein the bundle defines a central area that substantially encompasses the lower zones and wherein the laminated roofing shingles are double-layered, and
wherein the grooves of the lower zones of the stacked shingles results in the central area of the bundle having a height substantially identical to a height of a remainder of the bundle outside the central area.

5. The method according to claim 4 , wherein the reinforcement member defines a nail zone.
