Testing Dry Roof Surfaces
Buckleys roofing test kits have been used for many years to locate leaks in roof membranes. The Dry Roof
Pro' leak detector kit can be used to find faults in non-conductive roof membranes with great success.
Capable of testing non-conductive roofing membranes ranging from 64 microns to 25.6mm in thickness,
the Dry Roof Pro' provides an effective, quick and dependable method of testing a wide range of flat
roof coverings for leaks and defects.
Principle of operation
The earth lead from the Dry Roof Pro' is connected to a
convenient earth point on the structure. A high-voltage
DC current ― calculated against the membrane
thickness ― is applied (using an electrode) to the dry
surface of the membrane.
When there are no faults present, the membrane acts
as an electrical insulator by stopping the flow of current
out of the Dry Roof Pro'. When the electrode passes
over a fault or hole, the high-voltage jumps the
gap between the electrode and the water (or
conductive layer) under the membrane,
causing a current to flow.
The audible and visual alarm on the Dry Roof Pro'
will alert the operator, who can then mark the
area in need of repair.
Two types of electrodes are recommended for
testing; a phosphor bronze brush for uneven
surfaces, or a special roller for large smooth areas.
