Building inspection
Thermal camera for roof inspection
Use thermal patterns to prioritize moisture and insulation investigation safely.
Short answer
Roof moisture and insulation differences can change heat retention, but weather, membrane type and construction determine whether a useful pattern appears.
A practical workflow
- Choose suitable dry weather and a useful heating or cooling cycle.
- Scan from a safe position with consistent angle and distance.
- Map anomalies to roof construction and drainage.
Common mistakes
- Walking a roof solely to obtain a thermal image
- Inspecting during unstable weather
- Calling retained heat proof of moisture
Confirmation step: Use moisture verification and a qualified roofing inspection before repairs.
Choosing a camera for this job
Start with native IR resolution, thermal sensitivity, field of view and focus. Close electronics work often needs macro or manual focus; broad building scans benefit from a useful field of view and enough native pixels to resolve an anomaly from a safe distance. Compatibility and reporting workflow matter as much as the headline detector specification.
