Infrared Roof Survey

Infrared roof surveys identify trapped moisture in low-slope insulation, long before the leak appears on the interior. The work is best done at the right time of day — late afternoon into evening — when dry insulation cools faster than wet, producing a clear thermal contrast. We deliver these for capital planning, due-diligence assessments and pre-replacement scoping on commercial, institutional and multi-family buildings across Greater Vancouver.

Why Rain Leak Detection for infrared roof survey

Rain Leak Detection 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.

Pairs well with

Clients booking infrared roof survey often combine it with Electronic Leak Detection (ELD) or Flood Testing Supervision — particularly when the underlying issue spans multiple systems or when documentation needs to support a broader investigation.

How to prepare for your visit

1. Document what you're seeing. Photos, dates, sounds, water-bill changes, anything unusual. The more we know in advance, the faster we can locate.
2. Clear access to the suspected area. Move furniture, stored items, and rugs. Non-invasive methods still need clear sightlines.
3. Have system history ready. Recent plumbing work, prior leaks, renovations, age of property, prior insurance claims.
4. Confirm the email for your report. Photo-linked report delivered within 48 hours (often same-day for residential).
