The infrared camera detects heat, and wet roofing is hotter than dry roofing during its cooling cycle. The inspection crew finds, then verifies areas of moisture damage utilizing thermographic technology. It should be noted that the inspection is complicated by adverse weather conditions, variations in the roof system mass, uneven areas of solar load on a roof and the thermal variations that are inherent to the multitude of roofing designs. In light of all the complexities of this inspection technique, O.R.C. uses both a high quality infrared imaging system (sensitive to 0.1 deg. C.) and skilled certified thermographers to inspect your roof and provide your report.
