A limited thermal infrared survey was conducted at Fischer Honda in Ypsilanti, MI in general accordance with industry accepted standards for thermal imaging. The roof of the building was scheduled to be replaced due to issues identified by the tenants. Prior to the roof replacement, a thermal infrared survey was conducted to provide additional insights into the roofing systems.

From visual observation, the roofing membranes utilized on the roof were presumably single-ply Ethylene Propylene Diene Terpolymer (EPDM) and Thermoplastic Polyolefin (TPO) membranes adhered to an underlying insulation.


The thermal infrared survey can be considered limited for the following reasons:

  • The construction of the roofing systems was not characterized through destructive sampling or otherwise prior to the thermal infrared survey.

  • Destructive sampling was not conducted to verify the presence of moisture within suspected areas.



As a result of the thermal infrared survey, several thermal anomalies were identified within the roofing system.

Scaled drawings were developed for both color and thermal imagery. Roof sections and thermal anomalies were delineated within the drawing. Tables were developed with delineated areas quantified in square feet (SF).

Using the scaled drawings and acquired data, a final report was developed in general accordance with industry accepted standards.
