Roof Thermal Inspection in Victoria, 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 Victoria operations run under whatever airspace authorizations the location requires. Heritage masonry, government precinct, and YYJ-area airspace handled under authorization — plus Canada's oldest roof stock. 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. Victoria sits in our standing Vancouver Island 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 Victoria. 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.
