Tector, in collaboration with Teknologisk Institut and funded by We Build Denmark and the Danish Ministry of Higher Education and Science, has completed a landmark research project into how moisture behaves in flat roofs. The findings not only validate the role of sensors in construction but also accelerate the evolution of Tector’s moisture detection system, where real-time alerts transform risk into resilience for owners, insurers, and operators.
Shaping the next generation of building health technology
Testing Rockwool insulation in warm flat roofs revealed that water often travels to hidden cavities rather than being absorbed immediately. This highlighted the need for resilient sensors capable of operating under short-term submersion, directly informing the design of Tector’s next-generation flat roof sensor, which has a patent pending.
The real breakthrough goes the hardware. By combining field data with advanced AI analysis, the study confirmed that real-time monitoring can map moisture spread across insulation layers, identify patterns of seasonal movement, and predict risk before costly damage occurs. These insights are already being embedded into Tector’s SaaS platform, ensuring every customer gains actionable intelligence rather than raw data.
From measurement to prevention
One of the clearest outcomes was the impact of seasonal conditions. In summer, heat drives moisture deeper into insulation layers, creating condensation risks at the bottom of the roof. Without monitoring, these effects often remain invisible until damage is severe. With Tector’s platform, these shifts become visible in real time, enabling proactive interventions that prevent expensive repairs, claims, or downtime.
The project also uncovered how Rockwool insulation changes the electrical conductivity of water, a discovery now feeding into calibration improvements that will enhance the accuracy and predictive value of Tector’s reporting.
Real-time assurance for every stakeholder
One of the clearest findings was the impact of seasonal conditions on moisture. In summer, heat pushes moisture down into the lower insulation layers, driving up humidity and in some cases sending wood moisture levels above 100%. In winter, the opposite occurs near the surface, where cold air and underlying warmth create condensation risks. Lab tests couldn’t fully replicate the effect, real-world monitoring confirmed it, showing why live data is essential to understand what’s really happening inside a roof.
The collaboration reinforces the importance of live, data-driven assurance in construction and property management.
- Building owner: Protect long-term asset value
- Contractors and consultants: Reduce delivery risks.
- Insurers: Lower claims exposure.
- Data centre operators: Safeguard uptime and equipment integrity.
