Roof-Insulation-Drying

Efficient and eco-friendly damage restoration

Avoiding costs through smart damage repair

When refurbishing flat roofs, the entire roof structure is often torn down down to the base layer without considering alternative, more environmentally friendly and cost-effective drying methods. One such method is insulation drying, where dry air is passed through the insulation to remove moisture without removing the insulation.

When refurbishing flat roofs after water damage, the drying of the insulation layer plays a crucial role. ILD offers professional methods and procedures that reliably dehumidify the flat roof insulation layers and thus prevent long-term damage. Trust in our technologies and our experience, which ensure effective technical flat roof dehumidification.

We would be happy to advise you individually and adapt the measures precisely to the specific requirements of your building. Our goal is to ensure that you can use your property safely..

ILD is specialized in drying insulation layers for flat roofs and carries this out professionally. We use the most modern equipment and drying processes to remove water from the insulation layers. In this way, we dry water damage efficiently and renovate the roof sustainably in order to preserve the value of your property, prevent long-term damage and enable its full use.

We restore the function of your insulation layer through technical drying (dehumidification) and in this way quickly and cost-effectively save you the consequences and disadvantages of progressive water damage.

However, the following applies: The damage must be identified and repaired quickly, because insulation that has been soaked for many years can only be dried with great effort or even has to be completely replaced. If you use the innovative ProtectSys monitoring process with permanent monitoring, the smallest leaks are localized and the effort involved in drying the insulation layer as well as the effort required to eliminate the leak is kept to a minimum.

With ILD’s services, you protect property values ​​and contribute effectively to successful risk management.

Flat roof: Refurbishment vs. Insulation Drying

How much does technical drying of the flat roof insulation layer cost?


The costs for a complete roof renovation are on average between 280 and 350 € per square meter (sometimes significantly higher if the old materials are disposed of).

The costs for leak detection, water extraction and drying amount to a total of around 28 to 38 € per square meter.

The renewal or complete renovation of a flat roof causes costs that are many times higher than the drying of the insulation layer! And because it avoids waste, it is also the more environmentally friendly option.

Conclusion: In most cases, dehumidification is the best solution from both an economic and an ecological perspective.

Frequently asked questions

How does insulation drying work?

In a first step, the technical drying out of a flat roof involves extracting the standing water in the layer structure using a water separator in conjunction with a so-called side channel compressor or turbine. This procedure significantly shortens the drying time, as this water in the insulation layer does not have to be removed through time-consuming drying out. Now the actual part of flat roof drying begins, in which, similar to screed insulation layer drying, heated, dry air is flooded in using pulling and blowing units and drawn off elsewhere. For us, the drying of the insulation layer goes hand in hand with comprehensive services that ensure a complete renovation of the building. To do this, we use specialized equipment to extract moisture from the insulation layers. First, we analyze the water damage in detail to get an overview of the extent and the affected areas. Our technicians then install drying devices that specifically introduce dried warm air into the insulation layers and extract the existing moisture. This process ensures that the water is removed quickly and efficiently. We monitor the moisture in the insulation layers throughout the entire operation to ensure that drying occurs optimally. This will provide you with comprehensive water damage restoration and return your building to its original condition. The value is retained.

How long does it take to dry the insulation layer?

The duration of insulation layer drying depends on the severity of the water damage and the size of the affected area. Depending on the extent, the drying process can take anywhere from a few days to several weeks.

Our professional service ensures that all measures are carried out with maximum efficiency to enable the fastest possible drying time.

How much does insulation drying cost?

Drying the insulation layer is the most effective way to save costs when repairing moisture damage. Otherwise, the vapor diffusion barrier, the roof seal and the entire insulation layer would have to be laboriously disposed of and then completely replaced. A flat roof insulation layer drying saves you the environmentally harmful complete renovation. In the first step, the standing water within the individual layers of the roof structure is sucked out. For this purpose, a water separator is used in conjunction with a turbine or a side channel compressor. This procedure significantly shortens the time for the insulation layer to dry. Dried and heated air is then flooded in and then sucked out at another point.

The costs for drying the insulation layer vary depending on the extent of the water damage and the drying process used. Drying carried out by us offers several advantages: We use modern equipment and carry out the drying professionally, which means less follow-up work is required. This saves you unnecessary costs and ensures that you can continue to use your building as usual.
