Using Infrared Thermography in Flat and Low-Sloped Roofing Systems

As part of a roof asset management system, roof moisture surveys that use infrared thermography can help save substantial dollars. Thermal imaging care narrow roofing areas that contain moisture to a finite and targeted amount, thus ensuring that maintenance staffs or contractors need only replace these wet areas. Similarly, building commissioning agents can use thermal imaging results to see problems with design and/or construction defects during and after construction. This article explains how different roof types and compositions need special considerations to perform infrared thermography correctly. It offers tips and techniques for effect on-roof, under-roof, elevate-vantage-point, and aerial surveying.
