Personal
U.S. Bureau of Labor Statistics

BLS OEWS May 2025 national median hourly wage, SOC 47-4011.

U.S. Bureau of Labor Statistics

Wages and salaries were 70.0% of total employer compensation cost for private industry workers in June 2026 (ECEC), so total cost = wage / 0.70.

ilostat.ilo.org

Nominal 4.4% a year, 2015-2025 (ILOSTAT hourly earnings).

Preise
Abgeleitet HomeGuide

Midpoint of HomeGuide's traditional roof inspection $75-$200.

Abgeleitet HomeGuide

Midpoint of HomeGuide's standard visual drone inspection $150-$400. A drone company (AeroDeploy) quotes ladder inspections at $300-$800 instead: sources disagree.

Roboter
Annahme

Inspections where someone still climbs (soft spots, interior attic checks).

Annahme

Electricity price per kWh (USD). Check your bill; energy is rarely a big line.

Finanzen
Annahme

Annual financing / discount rate. Nobody publishes yours; 8% is a round mid-2026 commercial borrowing guess.

Annahme

Years in the NPV comparison.

Annahme

Share of a human service price that is labour (rises with wages). Used to escalate and to adjust US service prices to other countries.

Annahme

Share of a robot service price that is labour (pilot, technician). The rest is equipment, which learning curves make cheaper.

Annahme

Share of a lease or RaaS fee that pays for hardware (learns down). The rest is service and support (moves with wages).

What the spreadsheet misses

Sicherheit
Falls from roofs are a leading cause of construction deaths; steep or fragile roofs are where drones earn their fee.
Qualität
Drones capture every slope and thermal data; a person can feel soft decking.
Flexibilität
Inspectors also check attics and gutters by hand.
Edge cases
Trees, power lines and no-fly zones near airports limit flights.
Customer experience
Photo reports help insurance claims.
Jobs and redeployment
Inspectors increasingly fly drones themselves: the human and robot are often the same person.
Regulierung
Commercial drone pilots need FAA Part 107 (US) or local equivalent.
