Stop the drip before it becomes a disaster. We find and fix the leaks that other Sydney roofers miss.
A mystery leak is one of the most frustrating issues a Sydney property owner can face. Water rarely enters the roof and drops straight down; instead, it travels along internal beams, electrical conduits, and insulation, often appearing far from the actual entry point.
At TomKat Roofing, we specialise in precision roof leak detection in Sydney. Whether it’s a minor damp patch after a summer storm or a persistent drip that won’t go away, our team uses over 20 years of local experience and advanced diagnostic tools to identify the exact source of the problem. We don’t believe in “patch and hope”—we provide permanent solutions that keep your home watertight.
In Sydney’s volatile climate—from scorching heatwaves to intense East Coast Lows—a small leak never stays small. Ignoring a leak can lead to:
Constant moisture causes timber trusses to rot and internal plasterboards to sag or collapse.
Damp environments are breeding grounds for mould and mildew, which can trigger respiratory issues for your family.
Water ingress meeting your internal wiring or light fixtures is a major fire hazard.
What could have been a simple flashing repair can quickly escalate into a full roof replacement if left untreated.
We combine traditional roofing “detective work” with modern technology to ensure 100% accuracy.
Stop guessing and start fixing. Our licenced roofing specialists provide transparent, fixed-price quotes with zero hidden fees.
Different roofing materials fail in different ways. Our expertise covers the full spectrum of Sydney architecture:
We identify cracked tiles, deteriorated bedding and pointing, and blocked valley irons that cause water to "back up" under your roofline.
Metal roofs are durable but prone to leaks at the laps, rusted screw holes, or improperly installed flashings. We are experts in securing metal roof integrity.
Flat roofs require specialised knowledge of membrane systems and box gutters. We work with strata managers and business owners to manage large-scale drainage issues across Sydney.
When you search for roof leak detection Sydney, you want a team that is reliable, local, and licensed.
We understand the specific challenges of Sydney’s coastal air and storm patterns.
We operate with total compliance with NSW building standards for your peace of mind.
No "hidden surprises." You receive a detailed report and a clear quote before any repair work begins.
We prioritise active leaks to minimise the damage to your property's interior.
A thorough check of your roof’s exterior, including flashings, gutters, and ridge caps.
We enter the roof void to trace water stains back to their origin point.
Using moisture meters or flood testing to confirm our findings.
We provide a long-term repair roadmap to ensure the leak is gone for good.

Posted on Google Helen O'ConnorTrustindex verifies that the original source of the review is Google. I have had a fantastic experience with this business from start to finish. They are professional experienced, very fair and reasonable. We needed to replace the roof on our outdoor deck which was slightly tricky. Their advice and suggestions regarding product to use was sage. After a downpour there was a bit of a leak between the main building and the deck roof which they came out to fix which resolved the issue. There have been plenty of downpours since and everything is fine. I would highly recommend this company without hesitation. They are excellent.Posted on Google Ali BugejaTrustindex verifies that the original source of the review is Google. Tomkat did a great job and they were very pleasant to deal with.

Thankyou to TomKat Roofing and particulary Scott who did an excellent job repairing my roof. I had a water stain on the ceiling in one of my rooms, I called TomKat Roofing. They sent out a technician (Tim I think his name was) to have a look at the roof and that was followed by a very clear & comprehensive quote with what work needed to be done. The quote was supported by photos of the roof showing the problem areas. Tim was very polite & knowledgeable. He explained to me what needed to be done as a matter of urgency and what would need to be done for maintenance purpose and he showed me the photos. The price was very reasonable for the work that needed to be done. Scott carried out the repair work. Scott is very pleasant to deal and he knew exactly what he was doing. He worked just about all day to finish the job for me and I was very happy with the results and my roof problems have now been solved. I was very impressed with everyone I dealt with, from the ladies in the office who prepared my quote to Scott who completed the job , they are all very friendly and most of all they know their stuff. I think they're an asset to TomKat. I highly recommend TomKat Roofing and I would definitely use them again.Posted on Google Peter ThomasTrustindex verifies that the original source of the review is Google. Tomkat Roofing was a great place to do business with from the initial phone call, to Gary who came out to give me a quote arrived on time and was very helpfull in his advise.The job was completed in a highly professional manner. I will have no problems using this company for any future roofing work. Great work to the whole team at TomkatPosted on Google Sully 71Trustindex verifies that the original source of the review is Google. I contacted the team at TomKat roofing as I noticed a small leak in my daughters room during the recent storms and I was pleasantly greeted over the phone by the admin team who took down all my details and soon after I had the scheduling team call and arrange a suitable time to come out and review my concerns. The team promptly identified what the issue was and fixed it promptly. I can’t thank the team enough and whilst I hope I never need to call them again due to a roof issue, I would gladly recommend them to anyone looking for professional workmanship.Posted on Google Mike CohenTrustindex verifies that the original source of the review is Google. I highly recommend Tomkat Roofing for an efficient, well priced and solid quality roof replacement. My old, droopy and leaking terracotta tile roof is now straight and strong with a reinforced structure, new corrugated colorbond roof, gutters, facias, downpipes and leaf guard. Some of the key positive experiences I had with Tomkat Roofing are: The efficient and friendly office staff always responded quickly and kept me informed of the progress and when the tradesmen would be onsite. At the start of the job, within a single work day, they had a team of roofers and carpenters to get the old tiles off, the roof structure repaired/reinforced and the colorbond sheets with insulation secured so that my home was protected from the weather. Fortunately the weather was clear for a few days, but it was reassuring to know that they were prepared to work incredibly fast in the summer sun to keep my home safe. The site supervisors were always friendly and took the time to explain everything to me and respond to any concerns or questions I had about the job. Being an older build home, I had a few items that needed particular attention and everything was completed to my satisfaction. A word of advice for home owners looking to get a roof replaced with Tomkat Roofing: Raise as many of your objectives and concerns as you can as early as possible. I found the Tomkat team very responsive to my overthinking mind and everything I wanted to get done was outlined in the quote and addressed during the job. Also, they do tidy up and take away all the waste building material during and at the end of the job, which is great. But be prepared each evening to clean up smaller items that take time to find, like random screws or nails that were dropped, if you have children or pets accessing the area around your home in the evenings. It is unreasonable to expect the workers to find every dropped item each day if you also want the job done quickly.
