A snow removal hammer including a first pole assembly, a second pole assembly and a striking assembly. The first pole assembly includes a first pole. The first pole has a proximal end and a distal end. The proximal end of the first pole has a threaded portion. The second pole assembly includes a second pole. The second pole is telescopically inserted into the distal end of the first pole. The striking assembly includes a striking head. The striking head is threadedly attached to the first pole. The striking head is used to strike and smash ice that accumulates in roofs.

A ski device for use in combination with a snow removal device (such as a roof rake) is disclosed. The ski device includes ski portions that may be used to protect a surface (such as a roof surface) from damage by preventing a head of the snow removal device from directly contacting and scraping along the surface from which snow, ice, and/or debris is to be removed. The ski device also allows the amount of clearance between the head of the snow removal device and the surface to be adjusted. This allows a user to position the ski device to provide for a desired amount of clearance, which allows for adjustment of the amount of snow, ice, and/or debris that is to be removed, as well to allow for clearance of other structures (such as rain deflectors, etc.) on the surface.

A snow rake device comprises an open shape rake head operatively coupled to a gear assembly, handle assembly, and motor. The motor drives a flex shaft to rotate, which is pinioned into a linear reciprocating motion by the gear assembly, causing the rake head to move in opposite distal and proximal directions. Cutting bars on the rake head may then break up compacted snow and ice to more efficiently clear a building roof from snow.

A snow clearing machine is configured for operation on flat roofs and is designed to not damage the roof on which it is operated. The snow clearing machine is configured to leave a layer of snow beneath it, clearing the remainder, so that the machine avoids contact with the roof. As such, the snow clearing machine may be used on a flat roof or other fragile surface without damaging it.

An overhead snow moving device for moving snow positioned overhead includes a plurality of rods. Each rod has a first end and a second end, and comprises a plurality of nested sections. Supports are coupled to and extend between the rods proximate to top ends of the nested sections. A strut is coupled to and extends between the rods proximate to the first ends of the rods. First couplers are positioned proximate to the top ends of the nested sections. Second couplers, complimentary to the first couplers, are positioned proximate to bottom ends of the nested sections. Each of a plurality of extenders is angularly coupled to and extends from a respective second end of a rod. A plow is coupled to each of the extenders distally from the second ends of the rods.

A manually operated snow removal device designed for generally flat surfaces such as roofs includes a box-shaped device having a scalloped or undulating front and rear edge to cut through the snow; a leading bottom edge which protrudes from the box-shaped device to prevent the device from falling off roofs and a load belt made of a length of HPDE material for transporting the snow loaded on the load belt. A telescopic pole attaches to the device and allows the operator to remove approximately 10 square feet of snow and subsequently moved that snow to a desired location on the roof. The operator than moves the device such that the load belt folds over the edge of the roof dumping the snow in a desired location.

A building intelligence gathering, assessment and decision-support system including a GPS system deployed about the Earth and supporting a plurality of GPS satellites for transmitting GPS signals to the surface of the Earth. A building data sensor network, including a plurality of GPS-tracked rooftop-mounted sensors, are mounted on the rooftop surface of the building, and adapted for collecting GPS-indexed data specifying conditions on the rooftop surface at particular dates and times of the year. The building rooftop conditions includes one or more conditions selected from the group consisting of snow load conditions, windspeed and direction, and temperature. The system also includes one or more hand-held mobile augmented-reality (AR) based rooftop navigation and inspection devices, each configured for communication with communication servers within a data center over a wireless data communication network. Each hand-held mobile AR-based inspection device is capable displaying digital images of objects and scenery captured in its field of view (FOV) while the user is moving about the rooftop surface, along with graphical indications of GPS-tracked rooftop-mounted sensors collecting data regarding conditions on the building rooftop surface. By virtue of the present invention, users can now navigate building rooftops, inspect rooftop situations, identify where GPS-tracked rooftop-mounted sensors have been installed, and quickly determine where particular conditions have been automatically detected during rooftop inspections.
