The unspoken problem
The problem most roofs have — and nobody talks about
Landscape roofs, green roofs and buried waterproofing systems are complex. When they leak, the water travels. The entry point and the symptom are rarely in the same place. Visual inspection finds nothing. The contractor visits twice more. The defect liability period ticks down. Meanwhile the damage spreads — slowly, invisibly, expensively.
Vector changes that equation. We start with an initial site inspection to assess the roof, understand the construction and pinpoint the investigation strategy. From there, our buried leak location survey maps the defects — producing a contour map that locates leaks to within approximately one metre. No guesswork. No repeat visits hoping to catch it in the act. Just precision, backed by European sensor technology that nobody else in the UK can offer.
“Their approach accurately identified numerous leak locations, allowing us to resolve the issues with precision and minimal disruption — much to the relief of both the client and residents. I would highly recommend Vector for similar challenges.”
What we do
Three ways we protect the roof
Waterproofing Design Review
Independent review of your waterproofing specification at RIBA Stage 3. Before systems are locked in. Before mistakes become expensive. We tell you what the contractor won't.
Learn more →Sensor Monitoring & PPM
Embedded sensors. Continuous data. You stop hoping and start knowing. Ideal for complex landscape roofs, green roofs and CLT structures where moisture ingress is a latent risk.
Learn more →Buried Leak Location
Electrical field mapping. We locate the exact breach in your waterproofing membrane without destructive investigation. One visit. One report. One precise location.

The technology — and the people behind it
Precision instruments. Real expertise.
Vector has built exceptional partnerships with several niche technology suppliers across Europe. Our leak sensors come from Norway. Our buried leak testing technology comes from the Netherlands. These are precision instruments built for exactly this purpose — and we're the only firm in the UK with access to them.
But technology is only as good as the people using it. Vector's team combines a lifetime of flat roof experience — from hands-on defect investigation and quality assurance on some of the UK's most complex roof systems — with structural waterproofing consultancy at expert witness level. It's why we find what others miss, and why Tier 1 contractors and serious developers trust Vector with their most difficult projects.
