Leak testing and flat roof using R.O.S.I.
With R.O.S.I. we and our R&D partners have developed what is probably the most innovative sensor for the most reliable flat roof monitoring on the market. Rely on precise measurement results using this unique technology and minimise the maintenance and servicing
And the best part is: The R.O.S.I. sensors are available free of charge for NIS leak testing. Be it for monitoring the construction phase, as proof of successful renovation work or for drawing up leak protocols to achieve greater resale value - there is much to be said for R.O.S.I.

R.O.S.I. Sensor antenna
Placing R.O.S.I. Sensor antenna directly under the waterproofing seal. Access through measuring shaft (25 cm x 25 cm) for loaded areas
R.O.S.I sensor
Placement of the sensor on the vapour barrier to read out the humidity values
R.O.S.I. PROOF
Passive, maintenance-free monitoring system
With the R.O.S.I. PROOF equipment version, our patented sensors are installed on the entire roof surface according to a specified installation plan.
Manual reading of the sensors is carried out as part of the NIS leak test at the time of installation and as required, e.g. as part of maintenance cycles.
This allows the moisture value in the roof layer package to be determined at any time, covering the entire area and non-destructively. The cost of the sensors is included in the price of the NIS leak test.
R.O.S.I. HYBRID
Combination of passive and active monitoring system
With R.O.S.I. HYBRID, we offer you an individual monitoring solution for your flat roof that combines the best of both worlds.
In addition to the passive R.O.S.I. sensors installed throughout the roof, fully automatic R.O.S.I. sensors are installed at neuralgic points on the roof surface. DIGITAL PRO radio modules installed.
This combination creates a monitoring system perfectly adapted to the conditions of your flat roof for maximum safety at the best price.
R.O.S.I. DIGITAL PRO
Active monitoring system for permanent monitoring
Our active monitoring system R.O.S.I. DIGITAL PRO is a fully automatic monitoring system for permanently reading and reporting the moisture values and temperature in the roof layer package.
The data is transmitted 24/7 in a cloud-based customer portal and compared with the existing values so that alarms are triggered immediately in the event of moisture penetration.
R.O.S.I. DIGITAL PRO offers you the safest solution to monitor the moisture status of the roof package in real time.
