We at roofSec invented the world´s first fully automated leak-detection and monitoring-system with a built in just-in-time-notification. Just like a smoke detector, but for flatroofs and water instead of fire.
Our product consists of 3 main parts: A sensor-cable, a communication unit and the cloud-servers with our software and database.
The sensor cable is made up of a 100-meter cable plus a 50-meter connection cable. The main cable has a board with microprocessors, several electronical components and a capacitive sensor (which measures the moisture) on it. The gap between the boards is one meter and they are coated to resist those environmental impacts they have to deal with on the roof for 30 to 40 years. Every board has its unique ID, which is necessary for the leak-detection. The cable is installed in the roof between the vapour barrier and the insulation. So it is always situated in a constant climate with temperatures between 0 and 40 degrees Celsius, it is not exposed to the sun, to rain and it is protected against mechanical impacts. The sensors measure the respective moisture-level every 10 minutes and send the data via the connection-cable to the 12 Volt operated communication-unit (CU) which is situated in the electrical cabinet inside the house. The CU, which is also connected to the internet, reviews the data and when moisture is detected a signal is sent out to our cloud. Here the information is processed through fully automated algorithms, and when all false alert causes can be excluded it triggers a message to the home-owner via email , showing the exact position of the leak on the roof (within 2-4 m²).
Our system can be installed in nearly every type of flat roof - depending on the physical composition - and makes every flat roof a smart roof, an essential part of the Internet of Things. This creates several positive benefits, such as prolonging the durability of the entire building, saving much time in localizing a leak in the structure, saves resources which otherwise must be replaced for losing their function, and of course saving a lot of money in the long term in the event of damage to the roof. In addition, our system itself functions over the entire life-cycle of the building. Allowing for the scenario where apps or email may no longer be used in 30 years, adaptions to such new technologies and use cases can be made server-sided without changing the installed hardware or bothering the customers.
