What Does an Infrared Camera Find During Inspection?

An infrared camera, also called a thermal imaging camera, measures the heat radiating from surfaces. Wet materials cool down as water evaporates, so a damp spot on drywall or wood often shows up as a cooler area. The camera turns those temperature differences into a color image, with cooler zones in blues and greens and warmer zones in reds and yellows.

Because the camera sees only surface temperature, it cannot see through walls. What it finds are temperature patterns that suggest what is happening behind the surface. A professional uses the image as a starting point, then confirms the finding with a moisture meter or by opening a small access hole.

The camera cannot see through thick materials, and it cannot tell you if a damp area is fresh water, salt water, or condensation. It also cannot measure moisture content directly. A cold spot might be a leak, or it might be a metal stud conducting cold air from outside. That is why a pro never relies on the image alone.

The accuracy depends on the camera's settings, the distance from the surface, and the conditions in the room. Bright sunlight, a draft, or a running air conditioner can skew the readings. A good inspection takes those factors into account and uses the camera as one tool among several.

After the inspection, you receive a report with the thermal images and notes on any areas of concern. The report points out where moisture or heat anomalies appear, but it does not fix anything. You use that information to decide on next steps, such as calling a plumber for a suspected pipe leak or a roofer for a roof issue.

If the camera finds moisture, the next step is often a water damage inspection to determine the extent and what repairs are needed. For example, if drywall is wet, you might need drywall water damage repair. The cost of any repair depends on the size of the affected area, the type of material, and the cause of the leak. Policies vary, and your insurer decides what is covered.
