Roof Thermal Inspection in Langley, BC
Radiometric drone thermography over flat commercial and industrial roofs — trapped moisture, failed insulation, and developing leaks mapped before interior damage shows. Flown by Transport Canada-certified RPAS pilots serving Langley and the Fraser Valley region — since 1999 as BC's leak detection and inspection specialists.

Flying Langley: local context
Acreage estates, equestrian barns, and Willoughby's construction boom — roofs of every age in one township.
Local asset profile: Acreage estates with wells, septic, and undocumented private lines; Willoughby's dense new subdivisions; horse properties with buried water runs.

How the Langley survey runs
- 1
Evening flight window
Wet insulation holds daytime heat after sunset — the survey flies in that contrast window for maximum signal.
- 2
Radiometric mapping
Calibrated thermal plus visual overlay captures the full roof; anomalies are measured, not just colourful.
- 3
Verification
Thermal anomalies are confirmed as moisture (vs. shading or material artifacts) by pattern analysis and, where useful, on-roof spot checks.
- 4
Moisture plan
A roof plan with quantified wet zones — the document that turns 'replace it all' into targeted repairs.
Langley questions, answered
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.
Can you legally fly drones for inspection in Langley?
Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Langley operations run under whatever airspace authorizations the location requires. Acreage estates, equestrian barns, and Willoughby's construction boom — roofs of every age in one township. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.
How does Langley weather affect scheduling?
Aerial inspection flies in defined weather windows — wind, precipitation, and (for thermal work) the right temperature differentials. Langley sits in our standing Fraser Valley coverage, so we schedule against the local forecast and typically land the survey within days of booking rather than weeks. Mon–Sat, 8am–6pm Pacific.
What does roof thermal inspection cost in Langley?
Province-wide pricing — no regional premium for Langley. Single-asset thermal surveys typically start in the high hundreds; NDT campaigns and multi-asset programs are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes.
