How it works

  1. 1

    Evening flight window

    Wet insulation holds daytime heat after sunset — the survey flies in that contrast window for maximum signal.

  2. 2

    Radiometric mapping

    Calibrated thermal plus visual overlay captures the full roof; anomalies are measured, not just colourful.

  3. 3

    Verification

    Thermal anomalies are confirmed as moisture (vs. shading or material artifacts) by pattern analysis and, where useful, on-roof spot checks.

  4. 4

    Moisture plan

    A roof plan with quantified wet zones — the document that turns 'replace it all' into targeted repairs.

Frequently asked

How does thermal imaging find roof moisture?

Water has high thermal mass: insulation that got wet during the day re-radiates heat after sunset noticeably longer than dry insulation. A radiometric sensor measures that differential — wet zones literally glow against the cooling roof field, and the imagery maps their boundaries.

Why fly it instead of walking the roof with a camera?

Coverage, consistency, and membrane safety. A drone maps hectares in an evening at uniform angle and altitude with GPS-tagged frames — no missed bays, no foot traffic on an aging membrane, no fall exposure. Walking surveys still have a place for verification cores; the aerial map decides where.

Can you inspect any roof type?

Best results come from flat and low-slope membrane systems (BUR, mod-bit, EPDM, TPO) over absorbent insulation. Ballasted and inverted assemblies attenuate the signal and are assessed case-by-case. Metal and steep roofs are usually better served by our envelope thermal service.

What does the deliverable look like?

A scaled roof plan with outlined moisture zones, the radiometric evidence per zone, square-metre quantities, and repair-priority ranking — formatted for owners, roofing contractors, and insurers to act on directly.
