A system for removing shingles on a roof is provided. One embodiment includes a navigational apparatus for traversing the roof and a roof shingle removal apparatus attached to the navigational apparatus for removing the shingles. The improved removal apparatus pries existing shingles from the roof, and then stores the shingles in a debris bin before emptying the shingles in a precise location.

A system for diverting fluids consisting essentially of a wedge installed on a surface. The wedge is preferably triangular in area, but may be in the form of other shapes as required by the application. When viewed from the side, the wedge will often have a triangular shape because the front edge of the wedge is substantially lower than the rear edge, corner, or other shape to induce fluids and other materials to run off the sloped surface of the wedge. The system may include an adhesive to join the wedge and the surface. It may also include a sealing material disposed over the wedge and the surface to prevent incursion of fluids and other materials between the wedge and the surface.

A roof inspection and repair device is disclosed that can be wheeled along a roof to identify loose shingles and dispense the sealant necessary to secure them in place. The roof inspection and repair device has both a blowing system and a sealant dispensing system. The blowing system may include an air tube having an air tube inlet that can be connected to a blower and an air tube outlet. The sealant dispensing system may include one or more sealant storage containers connected to a sealant dispenser by one or more sealant tubes. The roof inspection and repair device may further include a shingle lift mechanism.

The invention is directed to an attachment for an oscillating or reciprocating tool. More specifically, the attachment is used to cut shingle. The attachment comprises a cutting portion comprising an attachment member adapted to be received by a head of the oscillating tool. The attachment also comprises a guiding portion operatively connected to the cutting portion. The guiding portion comprises at least one winglet defining a surface substantially parallel to the cutting portion and located at a pre-determined distance from the cutting portion. In use, the at least one surface is in contact with a guiding surface and trims material that exceeds the pre-determined distance as the tool is moved forward and parallel to the reference surface.

A system including a first tile, an actuator mechanically connected to the first tile, and a mechanical link mechanically connecting the first tile to a second tile, wherein the mechanical link is configured to allow the actuator to move the first tile a first distance in a first direction without causing the second tile to move, and to cause the second tile to move in the first direction when the first tile is moved in the first direction further than the first distance. A method for withdrawing a tile from an array of tiles including moving a first tile a first distance in a first direction without causing a second, adjacent tile to move, thereby distancing the first tile from the second tile, and withdrawing the first tile from a front face of the array of tiles. Related apparatus and methods are also described.
