Green Building Energy Sustainability (GBES) uses Infrared Technology to help locate moisture under the roof membrane. Leakage through a roof membrane can damage the roof deck, saturate insulation that will reduce energy efficiency and reduce roof life expectancy. No object in the IR images are detected via visible light wavelengths (400-700 nanometers) rather, only from infrared wavelengths of 3000-14000 nanometers. Lights and other relatively hot objects are very evident, but as a result of their heat, not light emissions.
The thermographic principles involved in a roof scan are indications of retained heat in moisture under the roofing membrane. The roof must be prepared by several hours of solar loading and then waiting until the roof surface has cooled slightly on a clear night sky. The water under the roof membrane will retain some heat and then show as a warmer area compared to the surrounding roof area. Other thermal anomalies may be evident so the determination of the characteristics may rely on the thermal signature. Water tends to have uneven flowing edges instead of square and straight edges.
Infrared Cameras and the knowledge to properly use them are powerful GBES tools for detecting water in buildings and electrical problems. Our inspectors are Level I, II, or III Thermographers trained to find moisture and electrical issues with this tool. If GBES can help you evaluate your existing building or plan for the construction of a new building, please give our staff of Engineers a call to start on your project. Our Office number is 940-891-3803.
We have a dedicated phone for our Spanish-speaking clients. If we can answer questions or schedule an inspection, please call us at 682-246-8150.
