Flat Roof Electronic Testing

The operator surrounds the area to be tested with a trace wire and uses two electrodes and a pulse generator to send an electrical pulse through the roof surface.

Flat roof electronic testing.

Electronic leak detection eld is remarkably quicker and therefore more cost effective than most other methods of roof leak detection. Electronic leak detection eld is compatible with almost 99 of flat roofs and roofing membranes capable of detecting pinhole sized leaks quickly and efficiently. Cost effective visual condition surveys ideal for use on any flat or low pitched roof to identify breaches in exposed membrane or ballasted systems. An exposed metal wire is then placed in a circle loop on the membrane and attached to the positive side of the testing equipment.

Applying technology to flat roofing. The entire roof area is then wetted with water which creates an electrical plate at the entire top side of the membrane when charged by the test. Using electronically charged bristles it is an non intrusive roof leak detection method can identify problematic areas with pinpoint precision. Useful for testing roof drainage systems metal coping joints and penetrations.

Electronic testing methods for flat roof leak detection. Wet roof testing requires the roof surface to be soaking wet as transmission of electricity through the water in the leak source provides the signal that there is a leak. The process was also adopted early on as a method for confirming the waterproofing integrity of membranes the world first project being the prestigious broadgate development adjacent. Integrity testing is the holy grail of building envelope work.

Electronic integrity testing is ideal for use on flat or low pitched roofs and because all roof membranes are more or less non conducting the electrical pulse from the wire ring circuit chooses a path across the moisture to where the leak is located. Electronic leak detection eld is a non destructive diagnostic used to identify water leak entry and areas of trapped water within a flat or low pitched roof construction. Dye testing can be used where sophisticated electronic leak detection systems are not applicable. Thornton roof leak detection was the first uk consultancy to offer this service starting in early 1987.
