“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 breach in your waterproofing membrane without destructive investigation. One visit. One report. One precise location.

From design review to lifetime monitoring
We protect the roof at every stage.
- 01
Design Review
We review the waterproofing design at RIBA Stage 3 — catching risks before they become defects.
- 02
Sensor Design
We design a bespoke leak sensor array tailored to the building's construction and risk profile.
- 03
Quality Assurance
On-site QA during installation ensures the waterproofing and sensors are commissioned correctly.
- 04
Long-Term Prevention
Planned preventative maintenance and continuous sensor monitoring — protecting the building for its lifetime.
Recent work
Real sensor installations.
A recent retrofit installation — coring through the existing build-up, fitting the sensor, restoring the membrane lap above. Hundreds of these now silently monitoring roofs across the UK.
