Abstract

The invention is directed towards a system and method for removing shingles from a roof comprising a shingle removal head, a boom arm assembly, a vacuum, and a containment bin. The head includes a frame that defines a shingle disposal area and includes a prying member having a lifting surface for engaging the underside of shingles and lifting them from the roof and directing them to the shingle disposal area. The head also includes a cutting member for receiving and decreasing the size of the removed shingles for removal from the head by the vacuum into the containment bin, both of which may be carried by a transportation unit. The head may be attached to the boom arm assembly that is carried by a transportation unit so that the assembly causes the head to engage and lift shingles from a roof, allowing operation of the head frame from the ground.

Claims20

Dependent claims

An apparatus for removing shingles from the surface of a roof comprising:

a moveable shingle removal head having a head frame;
a prying member comprising a plurality of prying elements individually and reciprocally biased across a prying width of said head frame for lifting and removing shingles from the surface of the roof and allowing biased reciprocal movement of said prying elements along a longitudinal axis for retraction of one or more of said prying elements upon contacting an elevated obstruction on the roof;
a cutting member carried by said head frame for cutting the removed shingles into smaller shingle pieces;
and
a shingle disposal section carried by said head frame for receiving the shingle pieces;
a shingle outlet formed in said shingle disposal section for the removal of the shingle pieces from said shingle disposal section;
whereby, when said apparatus is positioned and moved over shingles on a roof, said prying member engages beneath free edges of the shingles to lift and remove the shingles for being cut into shingle pieces for removal from said shingle disposal section through said shingle outlet wherein contact of one or more of said prying elements with the elevated obstruction causes said one or more prying elements to retract along said axis into a position elevated from the obstruction allowing said one or more of prying elements to continue operative movement over the surface of the roof, while allowing a remainder of said prying elements to continue operative movement over the surface of the roof without retracting.

4 more elements

A ground based shingle removal system for removing shingles from a roof comprising:

a mobile transportation unit stationed on the ground;
a moveable boom arm assembly carried by said transportation unit;
a shingle removal head for removing shingles from the roof carried by said boom arm assembly;
a prying member carried by said and comprising a plurality of prying elements individually and reciprocally biased across a prying width of said shingle removal head for lifting and removing shingles from the surface of the roof and allowing biased reciprocal movement of said prying elements along a longitudinal axis for retraction of one or more of said prying elements upon contacting an elevated obstruction on the roof;
said boom arm assembly being remotely operable for moving said shingle removal head over the roof so that said prying member removes shingles from a desired area of the roof;
a vacuum unit carried by said transportation unit, said vacuum unit including a vacuum hose carried by said boom arm assembly and connected to said head for transporting the removed shingles to the ground;
and
a cutting member carried by said head and disposed adjacent said prying member for receiving the removed shingles and cutting the shingles into smaller pieces to be removed by said vacuum unit.
