Locate trapped water in commercial roof assemblies before failure.
Flat and low-slope roofs are the most expensive envelope element to replace and the most commonly mismanaged. A thermal moisture survey, conducted at the right time of day, shows exactly where water has entered the insulation layer — long before it reaches the deck or the interior. We produce these for property managers planning roof-replacement budgets, for buyers conducting due diligence, and for envelope consultants needing condition data. The deliverable is a thermal map overlay with quantified wet-area square footage, suitable for capital planning.
Moisture Analysis is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.
We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.
Clients booking flat roof moisture survey often combine it with Building Envelope Imaging or Moisture Mapping — particularly when the underlying issue spans multiple systems or when documentation needs to support a broader investigation.

Yes — winter scans use the reverse principle, but require careful weather conditions.
We provide condition data; repair scoping is best done by your roofing consultant working from our findings.
