Abstract: An adjustable hopper for aiding in the transportation of old roofing material, such as shingles, to a refuse dumpster is herein disclosed. The hopper is inwardly tapered towards a false bottom and has a manually actuating release lever for vacating the contents through said false bottom. The hopper assembly is mounted on four height-adjustable leg assemblies manipulated by a handle. The hopper and leg assemblies are mounted on a support frame with heavy-duty caster wheel assemblies at each of four corners. The support frame is constructed so as to enable the entire hopper assembly to be positioned about a conventional refuse dumpster with a minimal amount of clearance.
