Abstract
Shingles with connectors consist of typical or standard roofing shingles joined together with connectors to form a row of shingle. The shingles are generally rectangular in shape with a top surface, bottom surface, top edge, bottom edge, a right edge and a left edge. The connectors are alternatively attached to the left and right edges of the shingles. The connectors act as hinges such that a specific number of shingles can be folded to form a bundle. Once the first shingle of the bundle is placed, the bundle is unfolded to form a row of shingles in proper position on a roof for attachment, thereby eliminating the need to place and position each individual shingle.
