Infrared Inspections

Infrared building inspections are a fast and noninvasive way to identify and document problem areas that may not be visible to the naked eye. Infrared thermography is the use of an infrared thermal imaging camera that can "see" and "measure" the invisible heat (thermal) energy that is emitted by all objects and produce thermal images (called thermograms) that can identify the thermal anomalies that represent the potential problem areas. Water intrusion, moisture problems, heat/energy loss, air infiltration, missing or damaged insulation, pest infestation and electrical overheating are all conditions that produce different thermal patterns. But not all thermal patterns or anomalies are problems. The inspection should include a thorough written report of all the findings and recommendations, as well as digital photographs and thermal images of the suspect conditions. 

Infrared inspections can be tailored to evaluate interiors, exteriors, roofing and entire buildings or can be focused on a specific area, such as water intrusion/moisture problems, energy efficiency, electrical systems and structural systems. Weather conditions prior to or during the inspection and time of day can have a dramatic effect on the accuracy of the infrared inspection or whether the inspection can be performed at that time. Exterior inspections cannot be accurately performed in rainy or windy conditions as it alters the surface temperatures of the components and does not allow for a true thermal picture. Most roofing inspections are performed in the evening after the roofing material has cooled. Long periods of no rain prior to the inspection may prevent discovery of water intrusion or moisture problems because the materials were dry at the time of the inspection and did not show a difference in surface temperature. Ideally there should be a 15 to 20 degree temperature difference between the inside and outside to provide the most accurate thermographic images.
