"Why do we use small Unmanned Aerial Vehicles (sUAV) for thermal imaging of roofs?"

A Bird's Eye View provides the best vantage point to see the stored energy in the wet insulation

See the Big Picture- A thermal image of the entire roof (in one image) is easier to understand than many images that have to be pieced together

Safety- Some roofs are dangerous to walk on... especially at night

Quality- Thermal Imagery is best with the proper view angles (see diagram below)
