What does infrared surveying detect?

Explanation:
Infrared surveying uses infrared thermography to capture surface temperature, translating emitted infrared radiation into temperature maps. On a roof, this shows up as hot and cold spots, which reveal where insulation is missing, damp insulation, or air leaks altering the heat flow. The key point is that the method detects temperature differentials, not the amount of moisture present, nor does it directly measure structural integrity or quantify air leakage rates. So while thermal patterns can hint at problems like moisture or leaks, the fundamental measurement is surface temperature differences, making temperature differentials the correct focus.
