Thermal Drones for Roof and Building Envelope Inspection
Wet insulation holds heat differently from dry insulation, and that difference is largest in the first hours after sunset on a clear day. That single fact is what makes a thermal drone the fastest way to survey a roof: a twenty-minute flight shows the moisture map a contractor would otherwise find by cutting cores. Unlike most missions, this one is won on timing and altitude rather than payload weight. You need enough resolution to separate wet from dry at a safe, legal height, a wide enough lens to cover a roof in few passes, and the discipline to fly in the window when the temperature difference is actually there. On residential work, that also means a small, quiet aircraft that does not draw a crowd.

What this mission demands
Fly the right hour
The survey works because wet and dry insulation cool at different rates. Fly too early and everything reads hot; too late and the difference has faded.
Resolution at a legal altitude
You want to read moisture patterns, not individual shingles. A 640-class sensor resolves roof detail from a height that keeps you inside Part 107 limits and clear of neighbours.
A wide enough lens
Wide coverage means fewer passes and a shorter flight, which matters on a commercial roof where the survey window is narrow.
A quiet, compact airframe
Residential work happens over occupied houses. A smaller aircraft draws less attention and is easier to fly in tight lots.

Questions buyers ask
Late afternoon into early evening on a clear day, after the roof has absorbed heat and begun to shed it. Wet insulation still holds heat while dry areas cool, and the contrast peaks in that window.
