A system and method for removing shingles from a roof with an automatic triggering of power to a fastener engaging member which is accomplished with the aid of relative movement occurring when a leading edge of the system encounters a fastener coupled to a substrate with shingle coupled thereto.

A shingle remover includes a fork riser, a pusher, and front and rear crank shafts. The fork riser includes forks separated by fork spacers. The forks are configured to push under shingles and separate them from roof structures. The fork spacers and forks pull out the nails associated with the shingles. Scoops on some of the forks urge pulled shingles away from the shingle remover for disposal. A fork carrier associated with the fork riser secures the forks to a front crank shaft while a cam associated with the front crank shaft periodically urges the forks forward under the shingles. A slot in the fork carrier engages with the rear crank shaft to limit movement of the forks to a substantially horizontal back-and-forth direction. The pusher includes tines that bite into the roof to oppose movement of the shingle remover as the forks push under and remove the shingles.

A roof cutter and a method of cutting a roof is provided. The roof cutter includes a base that is movable between a retracted configuration and a cutting configuration. In the retracted configuration, the blade is displaced from the roof. In the cutting configuration, the blade is positioned so as to facilitate cutting of the roof. The roof cutter includes a stop assembly and an engagement member that is configured to engage with the stop assembly when the base is in the cutting configuration, thereby establishing a maximum cutting depth. A dampening mechanism softens impacts associated with the blade moving to the cutting depth and absorbs vibrations associated with cutting the roof at the cutting depth. An adjustment assembly is configured to selectively adjust the cutting depth and/or to selectively restrain the base in the retracted configuration, thereby preventing the blade from cutting the roof.

A circle cutting system with a blade coupled to a body that rotates and is pressed into sheet material for the separation of circular portions from a larger sheet of the material, such as roofing material.

A motorized shingle remover may utilize a motor to rotate a plurality of cutting blades that may cut and remove shingles and roofing nails. The motorized shingle remover may have a body that covers the plurality of blades to protect the user and may have a vacuum that may pull away the debris or an air nozzle in front of each wheel to blow debris away. The plurality of cutting blades may be angled. The motorized shingle remover also may include a scrapper that may pull debris away from the plurality of cutting blades. The motorized shingle remover may include a braking mechanism. The motorized shingle remover may increase the rate and efficiency that shingles and roofing nails may be removed.

Systems and methods for collecting roofing debris are provided. A number of support poles are provided, each of which are configured to rest against a wall of a structure being serviced. A debris collection chute comprising a number of attachment points spaced apart along an upper edge of the debris collection chute is also provided. Each of the support poles comprise an attachment device configured to selective engage one of the number of attachment points such that the debris collection chute is suspended in a vertical orientation at an angle from the wall.

The present invention is a device to remove gravel from a roof. The device is a blade assembly vertically mounted on a riding drive mechanism, such as a tractor, and the blade assembly has a smooth, horizontal blade, such as used for snow plowing, and mounted proximate and parallel to the smooth blade is a serrated blade having an up position and a down position. In the down position, the serrations extend to the roof to loosen and remove gravel. In the up position, the serrations are above the edge of the smooth blade which scrapes the loosened gravel. A downward force is provided to force the serrations between the gravel.

The invention relates to a blade assembly for a tool for removing a slate from a roof, the blade assembly comprising: a blade having a length, a width, and a plurality of teeth; and a blade support, the blade being mounted to the blade support; wherein the blade support extends over at least 30% of the width of the blade; and wherein the thickness of the blade support to a first side of the blade is greater than the set of the teeth of the blade. The invention further relates to a blade assembly for a tool for removing a slate from a roof, the blade assembly comprising: a blade having a length, a width, and a plurality of teeth; and a blade support; wherein the blade support extends over a sufficient portion of a first side of the blade such that, in use, the teeth of the blade are prevented from coming into contact with a slate adjacent the first side of the blade assembly. The blade assembly may be included in a saw, further comprising a handle.

A roof waste removal assembly is provided and includes a chute system and a self-propelled expanding trailer. The chute system includes a roof guide and a gutter shield. The self-propelled expanding trailer includes a frame, an extension device secured to the frame, and a storage bin secured to the extension device.
