A thermal roof survey is the most effective way to find wet insulation and roof leaks. This guide covers how it works, when to schedule, and what to expect.
How thermal roof surveys work
After sunset, the roof cools. Wet insulation retains heat longer than dry insulation, creating a detectable thermal pattern. Our FLIR camera captures these patterns and maps them to the roof plan.
Drone vs manned thermal roof surveys
Drone thermal: covers 50,000 sq m/hour, no roof access needed, zero fall risk. Manned thermal: better for small roofs, detailed spot checks, access to tight areas. We offer both.
When to schedule
Best results: after sunset on a clear day, following 24+ hours of dry weather. We work with your schedule. Most surveys take 30-60 minutes.
