Electronic Leak Detection (ELD) for Roofs & Membranes in British Columbia
On a flat roof, a plaza deck, or a planter over occupied space, a single membrane breach can let water travel far before it surfaces. Electronic leak detection (ELD) finds the exact breach in the waterproofing membrane non-destructively — the precise, defensible method commercial and institutional owners and roofing consultants rely on.
Leaks.ca is the educational leak detection hub and service-support division of Leak.ca, helping BC property owners understand leak risks and connect with professional detection services when needed.
Electronic leak detection uses low-voltage (vector mapping) and high-voltage (spark) testing to locate breaches in roof, plaza-deck and below-grade waterproofing membranes by detecting where an electrical path forms through the membrane to the conductive deck below. It pinpoints the actual hole — even under ballast, pavers, overburden or green-roof assemblies — so the repair targets the breach, not the symptom.
- Punctures and seam failures in flat-roof and plaza membranes
- Breaches under pavers, ballast, planters and green-roof overburden
- Failed details at penetrations, drains and parapets
- Construction damage to below-grade waterproofing
Why It Matters
Pinpoints the actual membrane breach, even under overburden
Non-destructive and defensible for warranty and consultant review
Avoids replacing sound membrane to chase a single leak
Electronic Leak Detection (ELD) for Roofs & Membranes — FAQ
ELD applies a low- or high-voltage potential across the membrane and detects where current flows through a breach to the conductive deck below. That marks the exact hole — even beneath pavers, ballast or a green roof — so the repair targets the breach rather than guessing.
Low-voltage vector mapping can locate breaches on membranes under wet overburden, and the method is chosen to suit the assembly. It's the non-destructive standard for finding the precise leak point on plaza decks and protected membranes.
