Trusted by property managers to deliver a RICS-aligned defect detection system
Our Four-Step Process
Deploy
CAA-compliant drone surveys that are 90% faster than rope access. No scaffolding. No site disruption.
Detect
AI scans thousands of data points per roof, flagging defects by urgency, cost-to-fix, and degradation rate.
Decide
Live dashboard shows portfolio health, cost forecasts and compliance status. Filter by site or defect severity.
Deliver
Scheduled maintenance plans replace reactive callouts. Track repairs, measure ROI, prove compliance.
“It gave a great insight and fantastic detail of areas that had not been visible for us to see.”

Roofs fail quietly before they fail catastrophically
Invisible Defects
Annual visual surveys miss 60% of membrane defects that cause water ingress and structural damage.
Reactive Drain
Emergency repairs cost 5× planned maintenance. One undetected leak can exceed £50k in remediation.
Compliance Exposure
HSE work-at-height regulations put surveyors at risk. Insurers demand proof of proactive maintenance.
