ABSTRACT:
A roofing saw assembly and corresponding method of use for cutting into a roof a predetermined depth. The saw assembly may or may not include the saw itself. But it otherwise includes a frame having a base and a handle. Front and rear wheel sets are carried on the frame for supporting the frame in rolling movement above a roofing surface. A dead-man brake assembly is associated with at least one of the wheel sets wherein the brake is engaged with the wheel set until it is released to permit wheel rotation. A saw platform is carried on the frame, with the platform being adapted to support the power saw a predetermined height above the roofing surface. A height adjuster is disposed between the frame and the platform for adjusting the saw platform relative to the frame. The assembly can be used to cut roof sections of a predetermined size for easy and tidy removal.
