Flat roofs are common in commercial buildings, hospitals and residential apartment blocks and they can provide a range of benefits such as space for air conditioning units or solar panels. However, they are more prone to leaks than pitched roofs due to their design, materials used and damage caused by contractors. Flat roof leak detection can be challenging, but it is essential to prevent water damage and maintain the integrity of the building structure. All roofing membranes have a limited lifespan, but this can be extended by ensuring any weak spots which may result in water ingress are identified promptly and roof condition surveys are carried out to address any remedial work before a more costly roof replacement is necessary.

There are several methods for flat roof leak detection and Thornton Consulting has an experienced team of field testers and consultants who are skilled in determining the right procedure to identify any breaches. Signs of damage on a flat roof won’t be visible from the ground and even with a physical inspection of the roofing material, minor splits and cracks may not be identified with an untrained eye. A visual inspection won’t easily reveal the source of the leak if this is minute in size, but even pin-holes in the roofing membrane can result in significant damage over time.

An initial survey will determine the testing method most compatible with the roofing material, assessing whether a wet or dry test should be applied. As pioneers of the electronic integrity leak detection method in 1987, Thornton Consulting provides a comprehensive electronic leak detection service for clients throughout the UK and Ireland. The non-destructive testing of newly installed waterproofing membranes can be extremely beneficial for main contractors, roofers and architects to ensure the flat roof is watertight before the final sign-off, avoiding a time-consuming and expensive call-back.

Once the leak is detected, it is essential to carry out a repair promptly to prevent further damage to the building structure. Water infiltration may well not be visible within the interior of the property until there is a deterioration of walls and ceilings with evidence ofdamp patches or mould growth. This is especially relevant when the leak is above a part of the building which has limited or irregular access.

Thornton Consulting offer an accurate and pro-active flat roof leak detection and consultancy service to prevent water damage from occurring and to extend the life of the roof.
