Abstract: A shingle roll system for shingling a roof structure quickly and easily. The system includes an elongate shingle sheet having top and bottom surfaces, a pair of opposite end edges and a pair of side edges extending between the end edges of the shingle sheet. The shingle sheet has a dividing line extending between the end edges of the shingle sheet which divides the shingle sheet into exposed and coverage portions. The exposed portion has a width about five-sixths the width of the coverage portion.
