Roofing apparatus comprises: (a) a longitudinally elongated blade having a laterally presented sharp edge section adapted to initially penetrate between two stacked shingles, and a laterally presented thickened edge section adapted to spread the two shingles as the blade further penetrates laterally therebetween, (b) and structure to separate one of the two relatively spread shingles from the other by movement of the one shingle in a direction generally parallel to the other. Other mechanism allows feeding of the shingles, successively, off the apparatus and onto a roof.
