During the day, the suns energy heats up the roof membrane and insulation underneath. As the day transitions to night and the outside temperature cools, so does the roof system. The saturated areas of insulation hold heat longer than dry areas which allows the thermal imaging to be captured and show color variation.
Did you know? An anomaly is defined as an area of potential moisture within the existing roof assembly. An anomaly is detected by sensing the differential temperatures between dry and wet roof system components. As a roof assembly is cooling (during the evening), dry components will cool-off by emitting the heat absorbed during the day, while wet components will stay warm from the absorbed heat that is retained.
Infrared roof scans of in-place roofing is performed by aerial drone and portable handheld infrared camera to detect indications of wet roofing and insulation. This service is particularly applicable as it will locate areas of wet insulation and determine the possible source of water entry and locations into your building. Locations found will be marked on your roof surface or building envelope.
IRSC then generates a report that outlines the areas identified during the survey.
