Flat Roofs

Infrared Flat Roof Moisture Surveys

Infrared Flat Roof Moisture Surveys are used to detect and document latent moisture within a roofing system. The presence of moisture in a low slope roofing system causes changes in the thermal conductivity or thermal capacitance of the roof.

On a clear day, a roof surface is warmed by the Sun. While areas of the roof containing dry insulation resist solar loading, areas containing moisture readily absorb and retain heat. Following sunset, the roof surface begins to cool. Since wet insulation has a greater thermal capacity, those areas of the roof containing wet insulation cool off much more slowly than those areas of the roof containing dry insulation. By utilizing an infrared imager during post-sunset hours, areas of wet insulation are readily located based on their elevated temperature.

When an area of the roof with an elevated temperature is located during a walkover inspection, an invasive test is typically performed to verify the presence of moisture. This eliminates the possibility of false positive data as a result of variations in membrane materials, roof composition, or other environmental factors.

If moisture presence is confirmed, the perimeter of the moisture-damaged area is then outlined with spray paint on the roof surface. A thermogram is then recorded of the moisture-damaged area along with its size and location. Upon completion of the inspection, all imagery and associated data are incorporated into a comprehensive written report.

Reports from an Infrared Flat Roof Moisture Survey provide useful information for many purposes including:
  • Quality assurance of new or retrofitted roofs
  • Condition assessment prior to warranty expiration
  • Insurance claims to locate extent of storm damage
  • Document roof condition prior to sale or lease of building
  • Pre-bid documentation to help quantify the amount of roof to be replaced
  • Provide documentation for legal cases
