Why sensors in the existing roof are pure logic
Most flat roofs in the Netherlands are existing structures. They are often at the end of their planned cycle and therefore ready for replacement according to the long-term maintenance plan. However, replacement is not always necessary.
The real value lies in the existing roof package. If it is dry and performs well, it can last for years longer and even serve as a foundation for additional insulation.Sensors reveal whether this is the case. They prove whether a roof is suitable for extending its lifespan and can serve as a basis for making it more sustainable.
That is why sensors in the existing roof are pure logic.
Take action where necessary, save where possible
Sensors allow you to see where abnormalities occur: moisture in the roof, humidity rising in bad weather, an abnormal temperature profile. And that's where you take action. You leave the rest of the roof alone.
Result: lower costs, less material loss, greater certainty.
Extend service life
An existing roof often doesn’t need to be completely replaced just because the long-term maintenance plan says so. Sensors can determine whether the roof structure is still dry and stable. If it is, the roof can often last for years to come. Instead of making major investments, you’re buying time—time during which the roof continues to function normally and you can plan maintenance and replacement for when it’s truly necessary.
Those extra years of life are pure profit. Every extension means postponing major investments, lower costs, and less inconvenience for users or residents. At the same time, you are making a significant contribution to sustainability: the existing material remains in use, CO₂ emissions from the production and transport of new materials are postponed, and the total environmental impact of the building is reduced.
Our IoT sensors and LoRa make your roof smarter. Problems are detected faster, allowing you to take action before they become bigger. Whether you are responsible for a single building or an entire portfolio, make risk management easier.
Additional insulation as a logical next step
When an existing roof is dry and stable, it often provides an excellent foundation for making it more sustainable. Instead of replacing everything, the existing roof structure can remain in place and be fitted with an additional layer of insulation. This process—retrofit insulation—prevents unnecessary demolition and makes smart use of what’s already there. Sensors provide the assurance that this can be done safely: they confirm that no moisture is trapped and that the structure can support the new layer.
The advantages of additional insulation are considerable. It is significantly cheaper than complete replacement, because labor and material use are limited. It is also faster: the building remains in use and disruption is minimal. And it is demonstrably more sustainable, because existing materials are retained and CO₂ emissions from production, transport, and waste processing are drastically reduced. This makes sustainability not only possible, but also smart, affordable, and responsible.
Investment versus savings
A frequently asked question is: "Do the costs of sensors outweigh the benefits?" The answer is simple: yes. The investment in sensors is only a fraction of the savings you achieve with them.
Preventing just one leak can save thousands of euros in damage and repair costs. Postponing a complete roof replacement often pays off, especially for larger real estate portfolios. And reusing the existing roof structure when adding insulation not only saves costs but also time and CO₂. Compared to that, the cost of sensors is negligible—while the value they deliver is structural and demonstrable.
