Abstract: A portable tar kettle includes a steel containment body mounted on wheels and having a handle projecting therefrom with the handle including an integral gas line that interconnects to an external propane tank and internally registers with a gas burner located within the containment body. Disposed within the containment body is a tar cooking vessel that holds the tar, and other material, to be heated and melted. The tar cooking vessel includes a lid with an integral temperature gauge. When the tar is appropriately heated and melted, the tar cooking vessel can be removed and carried to the roof of the structure, and this process can be repeated as many times as necessary to effect roof repair and maintenance.
