A pipe lifting apparatus and method related thereto are provided, wherein the pipe has a base with outriggers, a vertically extending beam having a pulley at its upper end and a cable attached to a winch and extending over the pulley. The pulley and winch are oriented so that the cable extends naturally in line with a vertex between two of the outriggers such that, when a pipe in a vertical sleeve is attached to the distal end and is lifted by the cable, the pipe passes adjacent to the vertex. The apparatus is configured to raise pipes from a vertical pipe sleeve used in floating roofs of above-ground storage tanks. The apparatus can be used to raise and lower pipes and to move them around the upper surface of the floating roof of the tanks
