Electronic flat roof leak detection Testing a leaking roof Roof surveys

As a roofing surveyor, I'm often asked to do surveys on flat roofs that are leaking. Most of the time we can locate the problem without using any specialist equipment and the first thing to do on any roof is to have a visual roof survey undertaken as this is the most economic starting point.
If however, we cannot locate the roof leak on this roof inspection we will need to move to the next stage of leak detection. The electronic flat roof leak detection we are doing on this roof sends a pulse down into the roof to try to find moister deep down in the makeup of the roof, this kind of electronic flat roof leak detection is good for warm roofs as we can penetrate down to the lower deck of the roof where the water would naturally run. After griding out the roof we carry out two different sweeps of the roof trying to detection the wet spots in the roof and thus leading us to the leak in the flat roof. We mark out the sections that are the watest and form a moister map of the roof. This visual moister map of the flat roof shoud now indicate approximately where the water is getting into the roof and where it may be tracking. We can now start to investigate the roof membrane above to see if we can find where the leak is. Electronic flat roof leak detection is just one too lwe youse to try to find leaks in flat roofs Its a useful tool however it cannot be used on some rubber roofs and has a problem with metal that will give false readings. The electronic flat roof leak detection equipment we are using on this roof is a single that is suitable for finding leaks in relatively small roofs probably up to 100 m² . We also have electronic flat roof leak detection equipment that we can use on much larger roofs, these units have mobile heads and are on wheels so that the user can walk around the roof taking measurements.
