Roofing Moisture Surveys

What is a Roofing Moisture Survey?

A Roofing Moisture Survey is a diagnostic service that identifies trapped moisture within roof systems using advanced tools such as infrared thermography, capacitance meters, or nuclear gauges. This non-destructive process pinpoints wet insulation and compromised areas beneath the membrane, helping property owners make informed decisions about repairs or replacements. Ideal for preventative maintenance, warranty validation, or pre-renovation planning, moisture surveys extend roof life and prevent costly damage. The service includes detailed reports and visual maps of moisture-affected zones, enabling targeted repairs and budget-friendly solutions. Fast, accurate, and essential for protecting your building’s structural integrity.

Dec Scanner / Impedance Scanner ASTM D7954

Technical Testing Technologies uses mobile, non-destructive impedance scanners to detect moisture in flat and low-slope roofs. Ideal for dry surfaces, this method maps trapped moisture within insulation or substrates without damaging the membrane. Fast, accurate, and essential for maintenance planning, repairs, and protecting long-term roof performance.

Nuclear Gauge Moisture Testing

Technical Testing Technologies offers nuclear gauge testing to accurately detect moisture within roofing systems. This non-destructive method measures hydrogen levels to locate trapped moisture—even under insulation or thick membranes. Ideal for large or complex roofs, it delivers reliable results and supports targeted repairs and long-term roof performance.
