Roof repairs that keep your building occupants dry
Expert roof repairs for commercial and industrial properties in Brisbane and Southeast Queensland
Finding reliable roof repair services in Brisbane can feel like searching for a needle in a haystack. Many roofers prefer new builds, where they don’t have the challenge of working over an active business. At Core4, we specialise in diagnosing and repairing roof issues for commercial properties across Brisbane and Southeast Queensland, all without disrupting the day-to-day operations happening below.
For many Brisbane property managers and owners, the first sign of a roof related issue is a discoloured ceiling or a small patch of mould. Often, a plumber is called for a quick fix, but plumbers aren’t roofers. Their temporary solutions—such as slapping on some sealant—can sometimes make the problem worse, hiding the problem or trapping water and leading to further damage.
At Core4, we take a more thorough approach. We specialise in diagnosing tricky roof faults and providing localised, long-lasting repairs. Whether the issue is obvious or requires detailed investigation, we use advanced techniques like water testing and infrared scanning to pinpoint the exact cause of the problem.
And with our comprehensive roof reports, we help you fully understand the condition of your roof—critical, especially if you’ve never been up there yourself.

Our Roof Repair Services in Brisbane Include
Comprehensive Roof Assessments
A thorough roof report will help you plan for the future and at the same time highlight immediate issues. Many property owners and managers in Brisbane have never been on their roof, so they may not be aware of its condition. Our experienced team will inspect every inch of your roof and provide a clear, detailed report on any issues we find.
From there, we’ll create a customised repair plan that fits both your specific needs and your budget. Whether it’s a simple repair or partial roof sheet replacement, we’ll make sure your roof problem is fixed the right way the first time.
Advanced Water Testing Techniques
If the source of a leak isn’t immediately obvious, we use advanced water testing methods to identify exactly where the water is coming from. Depending on the issue, we might use dye testing (coloured water), flood testing (filling the area with water after blocking the drainage), spray testing (to simulate heavy rain), or infrared scanning to detect where the water is penetrating the roof.
These techniques remove the guesswork and help us pinpoint even the most elusive leaks, ensuring that our repairs address the root cause of the problem.
Long-Lasting Local Repairs
Once we’ve identified the issue, our team of experts carries out local repairs that are designed to last. We use high-quality materials and proven techniques to ensure your roof can stand up to the harsh Queensland weather. Whether it’s patching up a small area or replacing a section of roof sheets, we focus on delivering solutions that reduce the need for future repairs.
Complete Project Management
Our project management service takes care of everything, from the initial roof assessment to final inspection. We manage all necessary permits, enforce strict workplace health and safety protocols, and coordinate with other trades including electricians and air conditioning techs to ensure minimal disruption to your operations.
With Core4, you can trust that your roof repairs are handled by experts committed to quality, safety, and longevity.
Our remedial building works
Wyndham City Council
Stadium leak repairs | Melbourne
When the council’s new stadium roof sprung widespread leaks, they knew it could take a long time to resolve with the original builder.
With the roof covering a 14,000m2 stadium with basketball courts and other facilities, they needed an interim fix.
We diagnosed the problem through testing and trials and provided a temporary solution to fix more than 50 roof leaks.
This meant the basketball and netball games could continue without fear of players slipping on a wet court.
GARDA Industrial Warehouse

Safety-first Roof Maintenance
At a Morningside industrial warehouse in Brisbane, our long-term client, GARDA faced an issue: multiple water leaks were entering the factory floor below. Upon investigation, we discovered that the skylights had become brittle over time, with no safety mesh installed underneath, posing an immediate safety risk to the workers below. Additionally, the roof was compromised by rusted sheet ends and 50,000 rusted roof screws, threatening the structural integrity of the building.

About Core4
Most notable, the recent and successful completion of high-value complicated remedial works to one of our tenanted buildings. They worked closely with our engineers and stakeholders to diagnose problems and provide a scope that they would warrant. This provided a surety to us as building owners that the works would have longevity.
As always, we found Core4 to be up to the task with a trustworthy approach to the somewhat undefinable works. We would happily recommend them to others for both minor maintenance works and large-scale capital works.

Your thorough research and trials have provided us with a solution where everyone else has failed. This has allowed us to continue using our basketball courts without us worrying about injuries to our visitors. We are glad we found you guys.
