Visual photographs are taken earlier in the day or the next day. Both visual and infrared images are used to do the analysis by overlaying the AutoCAD drawing of the roof ‘over’ the digitized photographs and thermographs. The drawings are created indicating areas of suspected moisture contamination. HomeTech’s thermographers, use infrared inspection tools in conjunction with state of the art nondestructive moisture meter to locate hidden defects and potential problems that a typical roof inspection company simply cannot show you. The process measures the thermal properties of a low slope insulated or flat roof to identify differences in temperature across the entire structure.
How An Infrared (IR) Survey Detects Moisture
During the daylight hours the heat of the sun warms the roof of your building and at night the roof radiates that heat back towards the sky. This is known as radiational cooling. Wet areas of the roof have a higher mass and because of this they will retain the heat longer. Meanwhile areas that are dry, which have a lower mass, cool more rapidly. Infrared imagers detect and display the uneven heat dissipation and thereby accurately identify areas of the roof needing attention.

The recorded difference in heat signatures shows the Thermographer problem areas such as:
- Moisture/Water intrusion
- Insulation deficiencies
- Flat- Insulated Roofing leaks
- Electrical systems
- Structural issues
- Mechanical Issues
- Building / Home Energy Loss
- Foundation deficiencies
- Plumbing obstructions
