What we capture before engineering signs
Field notes aren’t glamour shots—they’re the measurements and constraints that keep change orders rare after permit.
Tilt and azimuth, shade CAD inputs, main service ampacity, roof attach vendor, and local fire setback rules—documented once, referenced in every downstream drawing.
Commercial flat roofs: we quote ballast versus penetration schedules separately from steep residential pitches so scope matches labor reality.
Structural surprises only move the job forward after a signed amendment—no silent rework on your invoice.
