Flat roof inspection is the most common form of infrared roof inspection. Many roofs need to be replaced prematurely due to moisture damage from leaks and improper installation. Infrared thermography has a proven track record in finding damaged portions of roofing structure so they can be repaired before water damage rots your whole roof.

Infrared roof inspections work on the principal that different materials in the roof have different thermal mass. In the daytime the sun heats the roof structure. After the sun sets the roof begins to cool. If there is a leak in the roof membrane the insulation inside the roof will become wet. The wet insulation has a higher thermal mass than the rest of the "dry" roof structure. As a result of this difference the "wet" areas will maintain heat energy longer than other areas providing the infrared inspector with a clear picture of the damaged area. The temperature difference between damaged and "dry" roof is very small (typically 2-4 degrees).
