The tools are a nail gun set to the right depth, a hook blade for cutting shingles, a chalk line, tin snips for flashing, and a caulk gun. Valleys, ridges, pipe boots, and chimneys each have their own flashing details that the roofer builds by hand. On flat roofs, the welder runs along a seam at a steady speed and the roofer probes behind it with a seam tester. Waterproofing below grade brings rollers, brushes, and sheet membranes applied to foundation walls.
Head cameras on the crew record what the roofer sees as they walk a slope, set a shingle to the line, and judge a nail placement. Fixed cameras on the ground and on the roof deck record the crew moving material, the staging, and the tear-off going into the dumpster. Collection runs through full working days on real roofs in five countries.
Researchers receive episodes by roof section or by seam run, with plain-language step labels: tear off, underlayment, chalk line, shingle course, flashing, ridge cap, membrane roll out, weld, seam probe. Failure tags cover nails that missed, flashing that had to be redone, and seams that failed a probe. Hand, nail gun, shingle, and welder tracking are optional, and we deliver in your schema to your storage.
Roofers on camera are consented and paid, and the footage is cleared for commercial model training. Request a sample and it will be in your hands within a business day.
