Thermal Inspections of Buildings


Managers of commercial, industrial, institutional and multi-family residential buildings are becoming more aware of the benefits of infrared thermal imaging inspections. For example, it is estimated that 40% of flat roofs, which are the standard in large buildings, will develop problems within the first year of service. The average lifespan of these roofs is seven years, but they could last for as long as twenty years if they are correctly installed and maintained. With replacement costs ranging from $8 to $10 per square foot, it makes sense to simply maintain the roof. Infrared roof inspections stand above all the other methods in prolonging the life of a flat roof structure.

Moisture intrusion and identifying the source of moisture intrusions in buildings has been made easier with the use of infrared thermal imaging. Inadequately flashed windows and doors, poor masonry construction practices and poor construction practices overall will allow wind driven moisture to enter the building envelope and cause damage to the interior of the structure. Inadequately designed and constructed drainage planes are prevalent in buildings with moisture problems. Moisture in the building can be detected with an infrared thermal imager due to evaporative cooling. Simply put, moisture trapped in the building envelope looks cooler than its surroundings.
