Proactively examine your roof for watertightness and possible leaks

Are you planning to install solar panels, a car park or a green roof on your flat roof? Do you, as a contractor, want to prove that your work has been carried out properly and do you want a report or certificate to avoid possible problems later on? Or do you, as a principal, want someone to check the work that was performed?

We can perform watertightness tests to find out whether there is any damage to the roofing and try to identify any spots where problems could possibly occur in the future.

Just as in the case of leak detection, the expert knowledge of a specialist is of paramount importance. The person who carries out the waterproofing tests must be an expert on roofs, have a solid understanding of all the regulations and know perfectly how to install the different types of roof coverings.

A thorough knowledge and an accurate interpretation of the results of various specialised tests are also of crucial importance.

The importance of watertightness tests

Insight into the quality of the installation

In addition to detecting possible problems, we always conduct a general inspection to detect the quality of the installation and identify any spots where problems could possibly occur in the future.

Extra security

Have your roof proactively checked before installing solar panels, a car park, a green roof, a roof terrace and similar! There is hardly anything more frustrating than discovering a leak after a roof has been installed and finished, after all!

Allocation of responsibilities

After the roofing work has been completed, you will receive a baseline measurement of the roof that you can refer to in case of problems after intensive use or further finishing on top of the roof.


Have you detected any problems with your roof and the warranty still applies? If so, you can still have the repairs carried out under warranty.

Detect leaks early

Often proactive tests like these bring minor problems to light. This allows you to intervene quickly before they grow any worse and major costs become unavoidable.

Our detailed reports can be used as evidence in the event of a discussion between different parties.
