Building Diagnostics Group is an industry leader in water intrusion diagnostic services. We provide fast and affordable infrared roof inspection services on multi-family, commercial, industrial and institutional buildings in Atlanta and across the nation.
Building Diagnostics Group (BDG), founded in 2002, specializes in the non-destructive detection, investigation and resolution of water intrusions. With our state-of-the-art thermography (FLIR) equipment, our team can rapidly identify hidden damage and provide you with an independent analysis of a roof’s structural integrity.
Extend the Life of Your Roof
It is estimated that up to 40 percent of all commercial roofs will develop leaks during the first year of service. The average life span of these roofs is seven to ten years, but they can last as long as 20 years if correctly installed and property maintained.
Far too often, the cause of a roof failure is the absence of proper maintenance and inspection. Periodic inspections and routine maintenance to correct deficiencies can significantly increase the long-term service life of any roof system and avoid expensive emergency costs that can arise without routine maintenance.
How Infrared Thermography Can Help
Infrared roof inspections work on the principle that different materials in the roof have different thermal masses. In the daytime, the sun heats the roof structure. After the sun sets, the roof begins to cool. If there is a leak in the roofing membrane, the insulation inside the roof will become wet.
The wet insulation has a higher thermal mass than the rest of the dry roof structure. This difference means that the “wet” areas will maintain heat energy longer than other areas, providing the infrared thermographer with a clear picture of damaged areas.
Roof Inspection Services
BDG offers several types of inspection services depending on the roof type, location, and client needs.
Walk-over method: Our visual photographic inspection uses professional grade infrared camera equipment to capture high-resolution digital images. These images can be provided in a traditional PDF report format that outlines concerns found during the inspection and recommendations for proper repairs. They can also be uploaded to our cloud reporting platform to produce a large format stitched image or a 3D model that can easily be annotated, measured, and shared with other construction managers, building owners, or the appropriate repair personnel.
Aerial method: Our aerial drone thermal infrared roof inspections are ideal for determining active roof leaks during due diligence of commercial or multi-family property acquisitions and can significantly reduce the time and expense of commercial roof inspections when compared to conventional methods. This service is performed just after sunset to detect warm trapped moisture under the roofing membrane. We can detect otherwise unobservable areas of water damage without requiring roof access or causing disruption to the occupants of the building.
BDG provides a written inspection report that includes IR images and digital photos of each “anomaly” or fault found during our visit. By request, we can mark each suspect anomaly on the roof so it can easily be assessed and/or repaired by a licensed roofing company.
