quality-control inspections, especially moisture detection. Unlike
other moisture-detection techniques, 100 percent of a roof
typically can be inspected with infrared devices.
Since the introduction of infrared cameras, prices have dropped
significantly; image quality has improved; and cameras—now
weighing about 2 pounds—finally are being designed with end
users in mind. As a result, infrared thermography has become a
popular tool for roof system maintenance and building
diagnostics.
However, the confusion many inevitably will face when trying to

technology still can pose a problem. With current prices ranging
