Nationwide Roof Surveys

Electronic Leak Detection & Roof Condition Surveys Nationwide
The services we offer to all of our clients include:
- Electronic Leak Detection
Earth Leakage Leak Detection
Often referred to as the "wet test", this method is ideal for use on any flat or low-pitched roof to identify defects in exposed membrane or ballasted systems without the need to remove ballast (loose stone chippings, paving slabs, landscaped).
This test is performed in wet conditions (rainfall) or with a hosed down wetted test area.
Method
A pulse generator emits pulses with a voltage of 40V which are conducted onto the roof structure via a wire ring circuit. Since all roof membranes are more or less non-conducting, the electrical pulse chooses a path across the moisture to where the leak is located and then flows over the damp roof in all directions to reach the ring circuit.
We can now determine the currents direction of flow and trace it back to its source. This source is exactly the spot where moisture is penetrating the roof membrane.
Holiday DetectorTest
Often referred to as the "dry test". This method is ideal for use on any flat or low pitched roof to identify defects in exposed membrane systems allowing for a quicker testing schedule identifying defects such as pinholes and punctures.
This test can only be performed in dry conditions
Method
The detector delivers, via a phosphor-bronze brush, a stabilised D.C. output voltage across the non conductive waterproofing membrane under test. Detection of defects is by an audible tone and a visual spark from the search electrode (brush)
- Thermal Imaging Surveys
Thermography is a non-destructive type of testing, and is an invaluable resource for predictive maintenance to assess flat roofs for damaged insulation and entrapped moisture allowing building owners to make an informed decision to action any defects identified to extend the life span of your roof.
All our Thermographers use the Flir Systems P640 range of equipment, the highest resolution camera available to ensure we pick up details lesser cameras may miss.

- Ultrasonic Leak Detection
The Ultrasonic Leak Detector allows us to identify leaks around glazing seals, metal profile and standing seam roofs and roof penetrations.
- UV Dye Leak Detection
Ultra Violet Dye testing allows us to test around areas where other testing methods are not suitable such as rain water outlets, planters and penetrations.
The dye used is invisible to the naked eye and can only be detected by U.V. light enabling easy location of ingress point in difficult to access areas. Standard dye testing is also available.
- Roof Maintenance Programme
Roof Surveys for Industrial and Commercial clients throughout the UK.
