A punch system for producing pilot holes through standing seam type roofing includes a punch having a striking end and a tip portion; and a punch guide that directs and controls action of the punch. The punch guide has an alignment member sized and shaped to conform to a raised rib portion of the standing seam type roofing; a tubular member affixed to the alignment member; and a force controlling mechanism contained within the tubular member and further including a punch centering sleeve, a plurality of spacers and a spring. The spacers set a stroke length for punch and sharpening of the punch is accommodated by rearrangement of the spacers.

A fastener driving tool and an adapter for a fastener driving tool are described herein for permitting accurate placement of fasteners with respect to an edge of a board (e.g., a top edge of a siding board). The adapter may include an adapter body having a central opening for receiving a head of a fastener driving tool and two or more pins positioned in the adapter body. At least two of the pins are positioned in the adapter body such that, when the central opening receives the head, the pins are equidistant from a center of a barrel through which the fastener driving tool drives fasteners.

A system including a plurality of photovoltaic shingles installed on a roof deck, a plurality of roofing shingles, such as asphalt shingles, installed on the roof deck, and a plurality of step flaps. One end of the roofing shingle overlays a first side of a corresponding one of the step flaps, and one end of photovoltaic shingle overlays a second side of the corresponding one of the step flaps.

A mounting device for covering a roof penetration in a roof includes a base formed from a sheet of material. The base includes a top, a bottom, a socket depending from the top toward the bottom, and an outer perimeter structure encircling the socket and depending downward from the top to the bottom. An internal reservoir is defined between the top and bottom of the base for holding a sealant against and in cooperation with the roof. The internal reservoir includes an upper cavity and a lower cavity. The upper cavity is bound within the socket. The lower cavity continuously encircles the socket and extends both below the socket and between the socket and the outer perimeter structure.

A plate advancement mechanism is configured to cooperate with a stack of plates consisting of alternating first and second roofing plates with alternately positioned indexing notches along an indexing edge of the plates. An indexer including at least one indexing tab that projects beneath the indexing edge of the plates reciprocates parallel to the indexing edge of the roofing plates between a first feed position and a second feed position. The indexer first feed position aligns the indexing tab with the indexing notch of the first plates and the indexer second feed position aligns said indexing tab with the indexing notch of the second plates. The indexer first feed position and said second feed position are coordinated with shuttle movement to release the lowermost roofing plate from the stack onto the shuttle by aligning the indexing tab (or tabs) with the indexing notch (or notches) of the lowermost plate

A roof cutter and a method of cutting a roof is provided. The roof cutter includes a basethat 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.
