Method for removing shingles from a roof

Abstract

A roof shingle peeler device which comprises a saw blade, a motor to operate the saw blade, a horizontal arm and skiis to regulate the depth of the saw blade, a wedge to remove the nails and shingles from the roof deck and enable the saw blade to cut the shingles into a predefined section, and a frame to facilitate the transportation of the predefined section of shingles for being received and collected into a bag for disposal. A hoist and return hoist are used to pull the roof shingle peeler device up and down the roof deck from the base to the crest while removing shingles.

What is claimed is: 
     
         1 . A method for removing shingles and nails from a roof deck having a base and a crest, the shingles lying in a plane substantially parallel to the roof deck, comprising the steps of:
 securing a hoist to the crest of the roof deck, the hoist accommodating a roof angle of the roof deck;   orienting a roof shingle peeler device at the base of the roof deck;   securing a hoist cable from the hoist to the roof shingle peeler device;   energizing a motor to drive a means for cutting shingles, the means for cutting shingles oriented substantially perpendicular to the plane of the shingles;   energizing a hoist motor to pull the hoist cable;   pulling the roof shingle peeler device up the roof deck from the base to the crest using the hoist and hoist cable;   controlling the pitch of the roof shingle peeler device as the roof shingle peeler device is pulled up the roof deck;   controlling the yaw of the roof shingle peeler device as the roof shingle peeler device is pulled up the roof deck;   lifting the nails under a predefined section of shingles from the roof deck as the roof shingle peeler device is pulled up the roof deck;   lifting the shingles from the predefined section of shingles upwardly from the roof deck as the roof shingle peeler device is pulled up the roof deck creating raised shingles;   cutting through the raised shingles from the predefined section of shingles as the roof shingle peeler device is pulled up the roof deck, the cutting occurring in a single cutting plane and separating the predefined section of shingles from the shingles that remain attached to the roof deck;   removing the predefined section of shingles from the roof deck as the roof shingle peeler device is pulled from the base to the crest of the roof deck;   deenergizing the motor to stop the means for cutting shingles; and   deenergizing the hoist motor to stop pulling the hoist cable.   
     
     
         2 . The method of  claim 1  and further comprising the step of directing the removed predefined section of shingles through a duct in the roof shingle peeler device. 
     
     
         3 . The method of  claim 2  and further comprising the step of collecting the predefined section of shingles directed through the duct into a bag attached to the roof shingle peeler device. 
     
     
         4 . The method of  claim 3  and further comprising the step of removing the bag from the roof shingle peeler device. 
     
     
         5 . The method of  claim 1  and further comprising the step of securing a return hoist to the base of the roof deck. 
     
     
         6 . The method of  claim 5  and further comprising the step of securing the roof shingle peeler device to the return hoist by a return cable, the hoist cable and the return cable correspondingly aligned into a straight line. 
     
     
         7 . The method of  claim 6  and further comprising the step of energizing a return hoist motor to pull the return cable. 
     
     
         8 . The method of  claim 7  and further comprising the step of pulling the roof shingle peeler device back down the roof deck from the crest to the base using the return hoist. 
     
     
         9 . The method of  claim 8  and further comprising the step of deenergizing the return hoist motor to stop the return hoist.
