Thermal imaging has been found to be helpful in identification of many types of construction deficiencies, plumbing leaks, moisture intrusion, roof leaks, and areas of inadequate insulation in structures. This same technology can be used in evaluating the performance of flat roofs, and in many cases, saving replacement of the entire roof covering by identifying the problem areas so they can be replaced as needed. Many times, these problem areas can be identified before any indications are apparent inside the building. Infrared conduction scans of structures will be performed by certified Thermographers. Convection scans using a blower door can also be performed.
