Roof Thermal Inspection in Whistler, BC

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.

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.

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.

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.

Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Whistler operations run under whatever airspace authorizations the location requires. Resort lodges, steep chalet roofs, and snow-load concerns — aerial inspection avoids winter roof access entirely. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.

Aerial inspection flies in defined weather windows — wind, precipitation, and (for thermal work) the right temperature differentials. Whistler sits in our standing Sea-to-Sky 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.

Province-wide pricing — no regional premium for Whistler. 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.
