Why use Infrared Thermography on Flat Roofs
By using infrared thermography, we find the trapped moisture and mark the wet areas so that repairs can be made surgically. This can save you money because you may not have to replace the roof as soon. By marking paint directly on the roof, repair areas can be seen by anyone standing on the roofs after the survey is performed.

How it works…
During the day, the sun radiates energy onto the roof and into the roof substrate, and then at night, the roof radiates the heat back into outer space. This is called radiational cooling. Areas of the roof that are of a higher mass (wet) retain this heat longer than that of the lower mass (dry) areas. Infrared imagers can detect this heat and "see" the warmer, higher mass areas, during the "window" of uneven heat dissipation. Heat loss and other IR services can be performed at the same time.

By using the information generated by a RoofScanIR™ report, the owner’s roofing professional can recommend cost-effective removal and replacement of wet components and draw documents to prepare an adequate roofing substrate to receive a recover installation to extend the satisfactory roofing system’s service life.
