If you're a commercial property manager in North Carolina trying to budget for a drone thermal roof inspection, you've probably noticed that nobody publishes prices. There are good reasons for that — every roof is different — but there are also bad reasons (some firms quote whatever they think you'll pay). This guide walks through what actually drives the price, what a fair quote looks like, and what to ask before you sign.
What drives the cost
- •Roof size — total square footage is the single biggest variable.
- •Number of buildings — separate roofs require separate flight setups.
- •Airspace requirements — Class B/C controlled airspace adds coordination time.
- •Site access and safety — gated facilities, escorts, and PPE requirements add labor.
- •Reporting depth — paired imagery and basic annotation vs. detailed professional reporting.
- •One-off vs. recurring — annual programs are dramatically cheaper per visit than one-offs.
- •Travel — sites within an hour of our Winston-Salem HQ skip mobilization fees.
Typical NC cost ranges
For a single commercial flat roof in the Piedmont Triad with no airspace complications: expect a few thousand dollars for a one-off thermal scan with a defensible anomaly report. Larger industrial buildings, multi-building portfolios, and roofs in controlled airspace (downtown Charlotte, near RDU, etc.) run higher. Annual recurring programs reduce per-visit cost significantly because mobilization, baseline data, and report templates are reused.
What you should be paying for
A professional drone thermal roof inspection should include radiometric—not merely colorized—thermal imagery, paired RGB context, and an annotated report that clearly separates observed patterns from possible interpretations. Infrared imagery alone does not confirm water intrusion. Thermal orthomosaics require a separate, established processing workflow and should not be assumed unless specifically included in the scope.
Questions to ask before signing
- •Is the thermal sensor radiometric (per-pixel temperature) or just a colorized visual?
- •Who reviews the imagery — a certified thermographer or just a pilot?
- •What's included in reporting — paired imagery, annotation, limitations, and recommended follow-up?
- •Do you carry aviation liability and commercial general liability?
- •Will you fly post-sunset for optimal thermal contrast?
- •What FAA authorizations are required for my site, and are they included?
