A multiple layer shingle having an anterior shingle layer and a posterior shingle layer, with the anterior shingle layer being of predetermined thickness between upper and lower surfaces thereof; comprising a web of reinforcing material coated with a solidified coating material, with the shingle having a butt portion adapted to be substantially covered by another shingle when installed on a roof, and a tab portion adapted to be substantially exposed when installed on a roof; each of which portions extend longitudinally of the shingle; with the butt portion having a lower end and an upper end and with the tab portion having a lower end and an upper end; and with the lower end of the butt portion merging with the upper end of the tab portion; with a layer of granules adhered to the coating material on the butt portion of the shingle; with a plurality of longitudinally spaced-apart first areas of granules adhered to the coating material on the tab portion of the shingle, leaving transverse longitudinally spaced-apart second areas between adjacent ones of said first areas; said transverse second areas having granules adhered to the coating material thereon; with the granules in said transverse second areas being of a visually distinct shading that is visually different than the shading of granules in said first areas; with transverse slots extending into said second areas from said lower edge thereof, toward said butt portion, separating said longitudinal tab portion into a plurality of tabs spaced apart by slots, with each slot being narrower in the longitudinal direction than the said transverse second area in which it is located; and with visually distinct granules of said second areas being longitudinally spaced apart on each side of each said slot, with each layer other than the anterior shingle layer comprising a web of reinforcing material coated with a solidified coating material with granules carried thereby, and with an adhesive securing the layers of the laminated shingle together.
