The Bailey survey: using technology for project success

Bailey Expertise

Looking to refurbish, renovate or redesign a roof? Our expert team uses the latest technology, to provide an in-depth survey of your or your client’s roof.

This survey is a vital first step to ensure that the ideal roofing solution is selected at the start of any refurbishment project, saving money and time in the long run.

Prior to starting any work on a roof, we offer an integrity test or a conditioned survey utilising thermography, electronic leak testing and core sampling to ascertain any building defects.

Missing insulation, dampness, moisture ingress and delamination are among the roofing weaknesses which the survey can bring to your attention before starting a project and, ultimately, help us help you find the most appropriate product(s) to fit you or your client’s budget and vision.


Thermal imaging

Thermographic testing uses an infrared camera to identify areas of the roof where water damage build up has caused thermal irregularities and energy inefficiency. This is a non-destructive testing procedure that’s far more effective than standard inspection techniques for identifying thermal irregularities and leaks.

Thermal imagery works by showing the varying temperatures across the roof surface. As liquids conducts heat at a faster rate than the dryer areas, wet areas of the roof can easily be distinguished from the dry, making leaks easily identifiable.

Thermographic and infrared surveys provide a decent overview of what is happening under the membrane, highlighting any thermal breaks and areas where heat is lost.  As well as helping to improve the thermal efficiency of a new or older building, thermal imaging is useful in other ways when looking to refurbish a roof. For instance, considerable savings can be made by partially stripping a roof and overlaying the areas that are actually dry rather than replacing the entire roof membrane.


Electronic leak detection

Bailey’s approach to electronic leak detection is simple yet highly effective. Using a dry test method, this technique detects pinhole penetrations in existing or new flat roof membranes. This procedure only locates the hole rather than assessing the extent of damage to the roof structure, that’s why we recommend that it is used in conjunction with thermal imaging. When combined, the two methods provides a comprehensive overview of the condition under the membrane as well as any leaks that there may be on the roof.


Core sampling

Core sampling is another method Bailey offers as part of its roofing survey service to give a conclusive answer when it comes to the current condition of a roof.  A sample of the roof will be cut out using specialist tools and assessed to provide information on the exact moisture content retained beneath the roofing membrane. Although a more intrusive testing method, core sampling will leave no lasting damage and still provide a true and accurate assessment of the state of moisture content in areas where leaks have been suspected. Each post survey report will provide all the information necessary for us to help you create an individually tailored solution to suit your roofing requirements.

At Bailey Total Envelope, we’re committed to giving you the full package. Combined with our wide range of high-performance roofing systems, these bespoke added-value services are there to support you at every stage of your refurbishment project.
