Identify the reasons of roof leaks
with our devices
CONTROFOIL system
The advantage is the ability to check the roof immediately without the need for a roof leak, because the spark test requires an electrically conductive substrate.
You can find holes with confidence and without the need for water in the roof!
So no unnecessary moisture in the thermal insulation!
Without CONTROFOIL foil?
Too bad. It could have been easy. You can only reliably check a new roof if it shows signs of leaking after heavy rain.
For measurement, water must penetrate through the leaks and create sufficient moisture to create an electrically conductive substrate for use in the spark test.
You will only find leaks through which it is already leaking into the roof.
There will be holes, but the water will remain in the roof!
Roof with CONTROFOIL detection foil
The spark test works even without the need for a leak
Step 1:Install CONTROFOIL under the mPVC sheet covering
Step 2:Use a spark tester to check the entire flat roof.
Roof without CONTROFOIL foil?
The spark test only works if the roof is leaking and there is moisture in the roof.
Step 1: Use an impedance hygrometer to locate moisture in the roof sheathing
(smaller RWS DETECTOR or larger DEC SCANNER )
Step 2: Localized damp areas of the roof can now be inspected
with the CONTROFOIL DETECTOR spark device for finding roof leaks.
