An overlay band of adhesive, continuous or discontinuous is provided, with granules thereon, increasing the thickness of the shingle material being made, in predetermined bands, relative to the remainder of the shingle material. The shingle material is slit longitudinally, and one portion can be laminated to another portion, preferably creating a multiple-ply laminated shingle material with thickened overlay portions and optionally with shadow line portions.

The shingles are then stacked and wrapped.
