ABSTRACT:
The invention is directed to a covering remover, the covering including roofing shingles. Removal of roofing shingles and other coverings presently requires hand tools, such as crow bars, hammers, shovels and nail pullers. This manual method is time and labor-intensive, as roofing needs to be removed in small individual sections. The present invention comprises a cylinder assembly with a rotatable shaft within the cylinder. Strapping is attached to and extends from the cylinder. A lifting force underneath the covering to be removed is accomplished when the cylinder assembly is rotated about its axis. This rotating assembly lifts whole sections of roofing and when removed from the cylinder, leaves the rolled-up section in a bale for convenient disposal.
