Invasive & Non-Invasive
-
Infrared
FEI’s in-house thermal imaging services
employ infrared technology for analysis of building surfaces and components, including
roofs and walls. Thermal imaging is conducted at night to detect thermal anomalies; it does not detect the presence of moisture. Once an anomaly is identified, invasive analysis is typically required to determine actual presence of moisture.

Deconstruction
Sometimes, it is necessary to disassemble completed
assemblies to accurately assess modes of failure, extent of damage, actual
construction, condition of materials, etc. Whenever possible, non-invasive methods are utilized prior to invasive testing to minimize the amount of deconstruction necessary.

Nuclear
Nuclear moisture testing utilizes regulated and licensed
equipment to accurately assess quantities of moisture within absorptive building
materials. This technique has been successfully utilized to assess the moisture
content of existing roofing materials prior to roofing replacement. This assessment
provides a basis for determining if existing materials can be utilized in new roofing
systems.
