Can thermography determine exactly where water entered the building?

Not necessarily. A thermal anomaly may indicate where moisture is affecting a surface, but the actual entry point can be elsewhere. Water can migrate through walls, roofs, slabs and other assemblies before producing a detectable thermal effect.

Can thermography be used to inspect roofs?

Yes. Under appropriate conditions, infrared roof surveys can help identify thermal anomalies potentially associated with differences in moisture or thermal behaviour within roofing assemblies. The effectiveness of the technique depends on the roof construction and environmental conditions.

Can thermography identify wet roof insulation?

It can help identify areas exhibiting thermal behaviour consistent with possible moisture under suitable conditions. These areas may then require additional investigation or verification before conclusions are made regarding the condition of the roof assembly.

Why is thermography useful for large roof areas?

Thermal imaging can allow large accessible surfaces to be screened efficiently for patterns or anomalies. This can help focus more detailed investigation on specific areas rather than assuming that the entire roofing system is affected equally.

Can infrared thermography replace a roof inspection?

No. Thermography is a complementary diagnostic tool. A proper roof assessment can also require visual inspection of membranes, flashings, drains, penetrations, parapets, previous repairs and other components.

Can thermography be used on building facades?

Yes. Thermal imaging can help investigate temperature variations across exterior walls and facades. Depending on conditions, anomalies may be associated with insulation, thermal bridges, moisture, air leakage or differences in construction materials.

Can thermography help investigate window problems?

Yes. Thermal imaging can help identify temperature patterns around window frames, perimeter joints, sills and adjacent wall assemblies. These patterns may indicate areas requiring further investigation for air leakage, insulation or moisture-related conditions.

Can thermography detect air leakage?

Thermal imaging can help identify surface-temperature patterns associated with air movement when there is sufficient temperature difference between indoor and outdoor environments. Other testing methods may be used when more detailed air-leakage assessment is required.

What is thermal bridging?

A thermal bridge is a location where heat transfers more readily through the building envelope because of material properties or construction geometry. Structural components, balconies, slab edges and certain wall connections can create thermal bridges.

Can infrared thermography identify thermal bridges?

Yes. Under appropriate conditions, thermal bridges can create recognizable surface-temperature patterns. Thermal imaging can help document these patterns and support further evaluation of the building-envelope assembly.
