FAQ – Roof Diagnostics

In lieu of our latest blog post, we’re feeling a little bit like rock stars. Do you know what else rocks? (Other than awesome roofing songs) Roof diagnostics.

Okay, hear us out. We’re big fans of all things roofing. More than that, we’re bigger fans of making sure your business is safe and risk free. Roof diagnostics ensures your roof isn’t an accident waiting to happen and if it is, you can make sure it never happens.

So what kinds of roof diagnostics are there?

We’re glad you asked.

Electronic Leak Detection

We identify trapped areas of water within a roof or potential leaks by using a small pulse generator. This clever little diagnostic is non-destructive and can detect leaks as small as screw holes. It works by identifying where there’s water in a roof by completing a pre-set ring circuit. Sounds tricky right? It is a little, but all you need to know, is it’s a quick and accurate solution to get to the bottom of any leaking commercial roof.

Moisture Probe

Works great on built up roofs where there’s heat generating sources at roof level. A moisture probe is placed into a small core of your roof, it then generates a scan of your entire roof, showing if and where it needs repairs. Once that’s complete we’ll be able to identify where the work needs to be carried out, which could potentially save you replacing your entire roof.

Thermal Roof Survey

Using infra-red technology, we can identify thermal anomalies in your roof. Sounds fancy right? It is. We’ll be able to show you where there’s defective areas and dangerous faults in your roof and exactly how they look in infra-red. It’s a concise way to diagnose roof faults. As a bonus, it’ll also shows you if there’s any insulation missing in your roof, along with how energy efficient your current roofing solution is.

Core Sampling

A small section of your roof is cut out (using specialist cutting tools) and tested for moisture content. The sample is weighed as is, dried out and weighed again. We’ll then identify just how much moisture (if any) is trapped within your roof AND we’ll also be able to test if there’s any asbestos in your roof. Don’t worry, any core samples taken are replaced appropriately and sealed to remain completely water tight and safe.

Extended Camera Survey

If you’ve got a smaller roof, or one that’s a tad fragile, we’ll often use extended camera surveys to diagnose issues. This simple little diagnostic gives a full photographic report of any potential roof problems.  This can be used on almost any roof in any location, it’s also quite handy if you’ve ever wanted to see photographs of your roof. You can then happily file them away, or make a collage – we don’t mind.


We saved the best till last, this is by far our favourite roof diagnostics solution, why? We get to fly a mini helicopter, attached with small camera, above and over your roof to create a quality survey of your roof. It’s great for areas with restricted viewpoints or restricted onsite access plus, we get to fly a helicopter. Everyone’s a winner.

Roof Diagnostics, Rock

That’s right, they do. With all these different ways to find out if your roofs in good health, it’d be crazy not to think so. More importantly, because there’s so many different diagnostic solutions available, there’s guaranteed to be one that’s right for you and your business.
