  "abstract": "A commercial roofing screw machine has: a plurality of screw guns that each properly place and install screw and washer pairs, both securely and in the right location, from separate magazines; automated operation with automatic or manual fastening pattern selection; sensors to recognize insulation sheets or marking lines, the high and low rib on the decking through the insulation, and torque; an indicia generator that marks fastener locations that did not hold correctly; and wireless communications for remote status checks, new programming uploads, troubleshooting, issue and error reporting, communicating with like or complementary machines to complete tasks, communicating with a records and reporting system to document fasteners installed correctly and which ones failed and were fixed by humans, and other beneficial purpose, and enabling plans upload with feature locations identified to select a fastening pattern based on location on a building and wind uplift ratings.",
  "claims": [
    "1. A commercial roofing screw machine, comprising: a conveyance configured to move said screw machine about a roof; at least one sensor operative to distinguish roofing subfloor grooves and gaps from elevated attachment surfaces; a plurality of screw machine modules configured to each simultaneously drive roofing washers and screws through a roofing layer into said elevated attachment surface and thereby affix said roofing layer to said elevated attachment surface; said conveyance and said at least one sensor cooperative to align each of said plurality of screw machine modules to misalign with said subfloor grooves and gaps during said simultaneous driving of roofing washer and screw through said roofing layer into said elevated attachment surface; a sensor configured to distinguish a successful screw installation from a failed installation, and produce an failed installation output responsive to distinguishing said failed installation; and a marking apparatus to produce a human readable indicia responsive to said failed installation output that is indicative of and uniquely identifies said failed installation.",
    "2. The commercial roofing screw machine of claim 1, wherein said marking apparatus further comprises a visible marking fluid discharge adjacent to said failed installation.",
    "3. The commercial roofing screw machine of claim 1, wherein said roofing layer further comprises sheet roofing insulation.",
    "4. The commercial roofing screw machine of claim 1, wherein said roofing layer further comprises a roofing membrane."

  "description_excerpt": "1. Field of the Invention The present invention pertains generally to the commercial construction industry, and more specifically to the construction and maintenance of a commercial roof. In a particular manifestation, the present invention provides an automated apparatus for attaching insulation and other materials to a commercial roof. 2. Description of the Related Art Constructing a commercial roof is a labor intensive and time consuming process. Many industrial and commercial warehouses, shopping malls, office complexes, hospitals, and the like are very large, and for exemplary purpose can occupy tens of thousands of square feet, with some measured in the hundreds of thousands and even a few in the millions of square feet. In addition to shear size, a typical commercial roof will also be constructed of a plurality of layers, for exemplary and non-limiting purpose such as tar or other bituminous materials, polymer or rubber sheets, insulation, and other beneficial materials. These layers are applied and in many but not all cases may be glued or otherwise adhered together and down to the roof structure. Commonly the insulation layers are affixed to the lower layers using screws and special washers in addition to being glued to provide more mechanical connection, rigidity, and immediate permanent physical connection to the roof, thereby preventing the otherwise lightweight insulation layer from shifting or blowing about. Similarly, various membranes may likewise be at least peripherally affixed with screws and special washers.",
