- a body defining a handle which extends generally longitudinal in a plane parallel to the roofing material surface to be worked on, said body having a top surface, an under surface, two ends, and two external side surfaces, said handle body being comprised of two halves which are mirror images of each other, the halves having internal facing side surfaces, each internal facing side surface having two notches;
- two spaced flange pieces extending from the handle ends, each flange piece having a proximal end attached to said handle and a distal end extending away from the body under surface, at an approximate 45.degree. angle;
- wherein each flange piece is comprised of a straight, flat extender section terminating in a transversely oriented L-shaped roller bearing section, said extender sections lying in vertical planes generally parallel to the planes of the handle side surfaces, said roller being rotatably mounted on the distal end of said L-shaped roller bearing section;
- wherein each notch has a depth equal to one-half the thickness of a straight, flat extender section, wherein the notches are adapted to form sockets for holding the extender sections when the halves are joined together;
