SHINGLE WITH REINFORCED NAIL ZONE AND METHOD OF MANUFACTURING

摘要

A bundle of laminated shingles is provided. The bundle includes a plurality of shingles having an overlay laminated with an underlay. The overlay has a tab portion with cutouts normally exposed on a roof and a headlap portion. The headlap portion has a lower zone adjacent the tab portion and an upper zone adjacent said lower zone. The lower zone has substantially no granules adhered thereto. The bundle defines a central area that substantially encompasses the lower zones of the stacked shingles. The shingles are stacked such that every other of the shingles is inverted and turned 180 degrees relative to an adjacent shingle. The shingles are double-layered, wherein the lack of granules in 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 of the central area.
