Moisture within a building envelope system can go undetected without visible signs, but infrared thermal imaging offers a powerful, non-invasive way to identify hidden issues. Wet insulation conducts heat rather than blocking it, increasing energy costs and reducing performance.

Infrared technology, especially when used after sunset, reveals temperature differences between dry and wet areas. Longwave or shortwave cameras are selected based on roof type and surface material. Accurate imaging requires skilled operators, and when done correctly, it enables targeted repairs and helps extend the systems lifespan.
