A hi-tech nondestructive and economical way to determine moisture in flat roof systems.
The roof structure is one of the most complex and costly parts of a building. Replacement roofs can cost as much as $8 to $10 per square foot when figuring in disposal costs of the old roof. While leaks themselves can be the owner’s biggest headache, any water introduced into the roof structure quickly results in other problems that are often more destructive and costly. An infrared scan can quickly and precisely locate areas of moisture in roofing insulation.

- Target maintenance dollars
- Early detection
- Prioritize roofing programs
- Find the source of leaks

The physical property of a material’s ability to store heat is known as thermal capacitance. The materials that roofs are made of have a low thermal capacitance. Water on the other hand has a high thermal capacitance. As the sun heats the roof up during the day, the moisture trapped in the insulation below heats up also. When the sun goes down and the roof begins to cool, the areas of wet insulation takes longer to cool down. Thus, the wet areas look like hot spots on the roof. While scanning the roof surface, the wet areas are marked on the roof with a can of marking paint. They are also transferred to a drawing to be included in the report.
