Abstract: A method and apparatus for shaping flat rectangular shingle blanks into curved shingles includes a heating chamber and shingle shaping device. The shingle shaping device is comprised of an elongate upwardly convex fixed shaping member and a plurality of hingedly mounted, downwardly concave movable shaping members. A plurality of shingle blanks are first steamed and then place on edge in side-by-side relation between the fixed shaping member and the movable shaping members. The movable shaping members are then moved into closed clamping relation with the fixed shaping member to clamp the shingle blanks into curved configuration for use with roofs having a thatched cottage appearance.
