ABSTRACT:
An apparatus for removing roofing material from a roof includes a framework with driven roof contact rollers and support wheels attached thereto so that the apparatus will roll on the roof. The apparatus further includes driven roof material cutters drum attached to the framework for cutting or shredding the roofing material as the apparatus moves over the roof on the driven rollers and wheels. The apparatus has a vacuum device for conveying the cut or shredded roofing material away from the roof material cutter drum for disposal. A suspension system interconnects the driven roof contact rollers and wheels so that the cutter drum will follow the contours of the roof over which the apparatus is moved so that the cutter drum will not skip over low section of roofing material to be removed nor dig too deeply into higher section of roofing material to be removed.
