Drone Thermography for Buildings, Explained
Thermal imaging is powerful and easy to over-sell. Here is an honest account of what drone thermography does for buildings, and what it does not.

What radiometric thermal is
A radiometric thermal camera records temperature data for every pixel, not just a false-colour picture. That lets anomalies be measured and compared, rather than judged by eye.
What it can indicate
Differences in surface temperature that can point to trapped moisture, missing or wet insulation, cold bridging and air leakage. On a flat roof it can highlight areas of suspected subsurface moisture for a closer look.
What it cannot do
Thermal imaging shows symptoms, not certainties. It does not see through walls, and it does not diagnose a cause on its own. Materials, weather and time of day all affect the reading.
That is why we flag anomalies for investigation rather than prescribing them as defects. Honest framing here matters more than a confident-sounding claim.
Getting a useful result
Capture conditions matter. Flown and interpreted properly, thermography directs a closer look to the right place, which saves opening up the wrong one. That is where it earns its place alongside visual inspection.
