Pre-Replacement Diagnostics

Many roofs are replaced too early and many are replaced too late. Pre-replacement diagnostics — IR, ELD where applicable, core sampling for layer history, drain and flashing audit — produce the data owners need to make the right call. We deliver these for property owners and consultants needing a defensible roof-replacement budget recommendation.

Why Rain Leak Detection for pre-replacement diagnostics

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 pre-replacement diagnostics often combine it with Infrared Roof Survey or Electronic Leak Detection (ELD) — 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).
