Infrared Thermal Home and Building Inspections

Infrared detects roof leaks even when the roof is dry-

Infrared reads the radiant energy emitted by any surface including a saturated roof structure when the roof surface is dry. In the daytime, the leaking roof is absorbing heat & energy, including the area that is saturated with water. Surface water that is above the roof surface evaporates during the day, leaving it difficult to determine the extent of the affected area.

After the sun goes down, the roof begins to cool. But the area affected by the roof leak, saturated by water, remains warm. When the roof cools to the point that the wet area temperature exceeds that of the dry area (the point of thermal inversion), the infrared camera will be able to detect that temperature differential, and will be able to clearly detect the temperature "signature" of the wet area. In this manner, only the affected areas need to be replaced, saving the client a significant amount on commercial flat roof repairs.

Infrared Thermal Inspections

Infrared Thermal Imaging (thermography) is a powerful tool for building performance inspections. Coupled with a blower door test, it vividly shows areas of missing building envelope components (such as the insulation in the first photo) and improper air sealing & the resulting air infiltration as in the second photograph. Note that the bath fan is not "on" in the second photograph. Attic air is coming through the unsealed, un-insulated fan housing. This will be a significant source of air leakage (and energy loss) in the winter, and adds to cooling load costs in the summer.

Infrared thermography can also be used to determine if specific components have failed or are at risk of failure. The window on the left has significant air leakage. The breaker on the right shows signs of stress and should be inspected further by a qualified electrician. Another use of this technology is moisture detection, and it can be used to find roof leaks (especially in commercial flat roofs) and moisture within wall systems.

All of our infrared scanning is conducted by a Certified Infrared Thermographer. Give us a call, and let's discuss how we can serve your infrared inspection needs.

Why use Infrared? What can it show that other inspection methods cannot?

Infrared Thermal Imaging, or thermography is a non-contact, non-destructive method of inspection that can give an early warning of issues of concern. Unlike traditional photography, it perceives a wavelength of [radiant] energy that cannot be seen with the naked eye. This energy can be measured, and used to give the thermal information of the subject or the condition being inspected.

What will infrared reveal about my home (or building)?

Infrared's unique ability to acquire thermal information allows it to show not only what is on the surface, but can reveal underlying conditions creating that situation. It can reveal missing insulation, points of air infiltration, failing building components, loose wire connections and overheating circuits. It is often used detect water damage, roof leaks, and uncontrolled moisture. In industry it is used to inspect facilities and equipment.

Is it expensive?

Our infrared inspection services generally cost no more than traditional building inspection services. All of our infrared inspections are conducted by a certified Level I Infrared Thermographer. The cost of the inspection (or "survey") is based on the scope of the area being scanned, and the amount time required to conduct a thorough inspection. Please call for a quote on your specific infrared inspection needs.
