Post-Storm Portfolio Leak Assessment in Delta, BC
After an atmospheric river, windstorm, or freeze event — every roof and site in your portfolio triaged by drone in days, damage and active water entry documented while the evidence is fresh and the insurer's clock is running. Flown by Transport Canada-certified RPAS pilots and confirmed by the ground crews serving Delta and the Metro Vancouver region — since 1999 as BC's leak detection specialists.

Flying Delta: local context
Tilbury industrial lands, port logistics, and greenhouse country — big roofs, big tanks, long lines.
Local property profile: Agricultural parcels with decades of private piping, Tsawwassen slab-on-grade subdivisions, and port-industrial lands.
Ground conditions: Lowland silts behave like Richmond — shallow water table, limited depth; the North Delta till ridge scans conventionally. Farm drainage networks add target density.

How the Delta survey runs
- 1
Portfolio intake
Site list, roof types, and any incoming leak reports set the flight order — known-vulnerable assemblies and occupied-critical buildings first.
- 2
Rapid flight wave
Visual capture documents physical damage — membrane displacement, flashing failure, ponding, debris strikes; thermal flags active moisture entry that hasn't shown inside yet. Multiple sites per crew per day.
- 3
Triage ranking
Every building graded: active entry needing immediate response, damage needing scheduled repair, and clean passes documented as clean — which matters for the claim file too.
- 4
Claim-ready package
Per-building reports with time-stamped, geotagged imagery — formatted for your insurer, your roofing contractor, and your own capital planning, all from one flight wave.
Delta questions, answered
Why fly the portfolio instead of waiting for leak calls?
Because leak calls report ceiling stains, not roof damage — and by the time the stain shows, the insulation is saturated and the claim is bigger. A post-event flight wave finds the breached membrane on the building whose tenants haven't noticed yet. Triage order set by actual damage beats triage order set by who complains loudest.
How fast can you cover a multi-building portfolio?
A flight crew covers multiple commercial roofs per day — a portfolio that would take a roofing contractor weeks to walk gets documented in days, without putting anyone on a storm-damaged membrane. Sequencing is risk-ranked, so your most vulnerable or most critical buildings are documented within the first wave.
Does the documentation help with insurance claims?
Materially. Time-stamped, geotagged imagery captured days after the event establishes what the storm did versus what was pre-existing — the exact dispute that slows claims. Clean-pass documentation on undamaged buildings also protects you when a tenant later attributes an unrelated problem to the storm. Pair with our insurance claim support service for the full file.
Can you legally fly drone leak surveys in Delta?
Yes — our pilots hold Transport Canada RPAS certification with advanced-operations capability, and Delta flights run under whatever airspace authorizations the location requires. Tilbury industrial lands, port logistics, and greenhouse country — big roofs, big tanks, long lines. Flight planning, NOTAM checks, and authorizations are part of the service, not your problem.
How do Delta ground conditions affect what the survey reads?
Delta ground is predominantly Fraser delta silts in Ladner/Tsawwassen lowlands, till ridge through North Delta. Lowland silts behave like Richmond — shallow water table, limited depth; the North Delta till ridge scans conventionally. Farm drainage networks add target density. For buried-leak work that matters: escaping water changes the moisture and thermal behaviour of exactly that ground, and our analysts interpret the surface signal against the local soil character — then our acoustic ground crews confirm the suspect zones before anyone digs.
What does post-storm portfolio leak assessment cost in Delta?
Province-wide pricing — no regional premium for Delta. Single-site surveys typically start in the high hundreds; network corridors, portfolios, and multi-asset programs are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes.
