ProtectSys CONTROL – Precision Leak Testing at the Right Moment
Moisture damage in flat roofs often goes unnoticed—until costly repairs are needed. A professional integrity test detects even the smallest leaks before they become serious. ProtectSys CONTROL delivers precise, targeted measurements—efficient, reliable, and completely non-invasive.
With over 25 years of experience, we know: more than 50% of all flat roofs are already leaking at the time of handover. Without regular inspections, roof tightness becomes an unpredictable risk—like surfing the internet without antivirus protection.
ProtectSys CONTROL delivers security through targeted testing—exactly when it’s needed.
Unlike permanent monitoring systems, ProtectSys CONTROL offers precise, on-demand analysis at the right time. This allows leaks to be detected early and costly damage to be prevented. Preventive testing is the key to a durable, well-maintained flat roof.

FAQ
Which Methods Are Used to Test Flat Roof Integrity?
We use various proven methods to test the waterproofing of flat roofs. These techniques not only determine whether the roof is watertight, but also allow for highly precise leak detection.
One of the most widely used methods is potential equalization testing, also known as the Electric Field Vector Mapping (EFVM®) method. It works by creating an electric field across the roof membrane to accurately locate leaks. A major advantage of this technique is that it can be applied even in hard-to-access areas—such as green roofs, gravel-covered roofs, terrace systems, or underground garage membranes.
In warm roof constructions, where the waterproofing layer lies above the insulation, the test current may not always find a conductive return path. To ensure reliable testing in these cases, ProtectSys offers a specialized procedure that combines the benefits of EFVM with a conductive layer installed beneath the membrane.
In addition to EFVM, we offer other certified leak detection methods that can identify damage early and with pinpoint accuracy. After each inspection, we provide a detailed report on the condition of your flat roof.
How Long Does Flat Roof Leak Testing Take?
The duration of a flat roof integrity test depends on the size and construction of the roof. In most cases, a thorough inspection can be completed within a short time frame—typically without any disruption to building operations.
You’ll receive a clear and reliable assessment of your roof’s condition in no time.
What Does a Flat Roof Leak Test Cost?
The cost of a flat roof integrity test depends on several factors: the testing method used, the size of the roof, and any additional effort required due to specific roof conditions.
At ILD, we believe in transparent pricing and tailored solutions. After a detailed consultation, we’ll gladly provide you with a customized quote that meets the exact needs of your building.
