ABSTRACT:
Laminated shingles are manufactured from roll stock roofing material that is wider than that used to make similar laminated shingles. The roll stock includes longitudinal edge strips having a reduced thickness. The roll stock is cut into strips of tabbed top sheets and backing sheets. The strips of material used for the backing sheets are at once wider than commonly used in the industry, and include the longitudinal edge strips of reduced-thickness material. Because the backing sheet is wider two rain seal strips are laid down on the backing sheet prior to being laminated to the tabbed top sheet. The backing sheets are laminated to the tabbed top sheets with the longitudinal edges aligned. The wider backing sheet provides a substantially wider nail zone. In addition, since it allows for a second rain seal strip, provides somewhat more protection against leakage. The portion of the backing sheet that comprises the added width is relatively thinner than the remaining portions of the sheet. Paired shingles may therefore be oriented adjacent one another in opposite directions and stacked and bundled. The total thickness of the stack will be the same throughout the stack, so the stack of shingles is flat.
