Abstract

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.

Dependent claims

A roof cutter that is moveable between a retracted configuration and a deployed configuration, thereby moving a blade of the roof cutter from a disengaged position to an engaged position relative to a roof structure, the roof cutter comprising:

a base having an engagement member, said base being movable between a retracted position and a deployed position, thereby moving the roof cutter between the retracted configuration and the deployed configuration, respectively;
a linkage assembly engaged with said base,
wherein said linkage assembly comprises a second linkage member extending from a first linkage member towards a rear portion of said base,
wherein said first linkage member is rotatably coupled to a front portion of said base,
wherein a stop assembly is coupled to said second linkage member,
wherein said stop assembly extends below an adjustment assembly and along the second linkage member,
wherein the adjustment assembly selectively adjusts an amount of travel of the second linkage member relative to said engagement member, and
wherein said engagement member is configured to engage with the stop assembly when the roof cutter is in the deployed configuration.
