Concrete Rooftop Waterproofing & Leak Repairs

Concrete rooftop waterproofing plays a critical role in protecting commercial or multi-residential buildings – especially for those located in Brisbane, the Gold Coast and Sunshine Coast. Being constantly exposed to Queensland’s harsh climate – over time even the most durable rooftop waterproofing systems can break down, leaving your building vulnerable to costly water ingress, concrete damage and internal leaks.

Whether you’ve noticed signs of moisture seeping into the top floor of your building, or your rooftop membrane is showing visible signs of wear – our experienced team is here to help.

We specialise in identifying the source of rooftop leaks and delivering tailored remedial waterproofing solutions backed by over 15 years of experience.

Our team provides a full assessment and tailored repair strategy for your rooftop, which may include removal and re-application of trafficable membranes, crack injection or concrete repair.

We use premium waterproofing products, industry-proven techniques and modern equipment to restore the integrity of your roof and protect your building long-term.

Common Causes of Leaking Concrete Rooftop Areas

Rooftop areas—particularly those in older or high-use buildings—are often overlooked when it comes to regular maintenance. But as the first line of defence against water ingress, the rooftop waterproofing membrane must be monitored and maintained to remain effective.

Here are the most common causes of rooftop leaks we see throughout South East Queensland:

UV Degradation and Weather Exposure

Constant exposure to sunlight and harsh weather conditions slowly breaks down membranes, leading to cracks, bubbling, or brittleness that allows water to penetrate.

Water Ponding and Poor Drainage

Flat or low-sloped roofs can experience water pooling if not properly graded or drained, increasing membrane stress and the risk of leaks over time.

Failed or Deteriorated Membranes

Older membrane systems may shrink, lift at the seams, or crack, especially around penetrations such as vents, ducts and pipework.

Structural Movement or Settlement

Rooftops are prone to movement due to thermal expansion, structural settlement or vibration, which can cause cracks or split joints that compromise waterproofing.

Damaged or Poorly Sealed Penetrations

Pipe penetrations, plant equipment bases, lift overruns and ducting all create weak points if not properly sealed—often the origin of hard-to-find leaks.

Inadequate Maintenance and Repairs

Temporary patch jobs or poor workmanship during repairs often fail under pressure, allowing hidden leaks to worsen over time.
