The Complete Roof Leak Detection Process
Water is deceptive. A stain on your bedroom ceiling doesn’t always mean the hole in your roof is directly above it. Water routinely enters through a tiny crack, travels down rafters, foil sarking, or batten lines, and drops several meters away.
That’s why accurate leak detection is the crucial first step.
How We Locate Hidden & Complex Leaks:
Visual & Structural Inspection: We inspect your entire roof exterior—examining tile beddings, ridge capping, metal sheet laps, barge boards, flashing seals, and skylight joinery.
Controlled Water Ingress & Spray Testing: We systematically simulate rainfall on isolated sections of your roof (valleys, penetrations, and flashings) to isolate the exact point of entry.
Internal Ceiling Cavity Audit: Our team inspects the underside of your roof inside the roof cavity to trace moisture paths, inspect underlayment/sarking condition, and evaluate timber framework.
Detailed Diagnostic Findings: We provide you with an honest breakdown of the cause—whether it’s broken tiles, failed screws, rusted flashings, or blocked box gutters—along with a clear repair plan.
- Why We Don’t Rely on Thermal Cameras or Moisture Meters: Thermal cameras measure surface temperature differences—not water entry points. A thermal camera might highlight a cold spot near your ceiling light, but the actual hole in your roof could be at a valley 3 meters uphill. Moisture meters simply confirm what you already know: it’s wet. We use physical cavity audits, structural pattern recognition, and controlled water testing to find the true point of origin every time.

Signs Your Sydney Roof Has a Hidden Leak
If you notice any of the following warning signs, call for an inspection immediately to prevent major timber rot and gyprock failure:
Ceiling Stains: Yellow, brown, or dark water rings on plasterboard ceilings or upper walls.
Bubbling Plaster or Paint: Peeling paint or sagging ceiling gyprock holding water weight.
Damp or Musty Odors: Lingering damp smells in bedrooms or upper level hallways.
Dripping Sounds: Rhythmic ticking or dripping sounds inside wall cavities or roof voids during rain.
Mould & Mildew Growth: Dark spots spreading across ceiling cornices or high wall corners.

How We Find Leaks That Others Miss (Our Proven 5-Step Process)
Step 1: Leak Pattern Audit
We analyze when and where water appears inside (heavy rain vs. wind-driven, single spot vs. spreading) to isolate the water path.
Step 2: External Visual Inspection
We inspect high-risk entry points—flashing, valley trays, ridge capping, sarking, tile beddings, and sheet laps.
Step 3: Strategic Tile/Sheet Removal
When needed, we carefully lift specific tiles or metal sheets to inspect underlying battens, timber framing, and sarking moisture trails.
Step 4: Controlled Water Spray Testing
The ultimate proof. We systematically simulate targeted rainfall using a hose while monitoring inside to prove the exact point of entry before starting repairs.
Step 5: Photo Findings & Fixed-Price Quote
We show you photos of the damaged area, explain the exact cause, and provide an upfront quote. Your $110 fee is credited directly toward the repair if you proceed.
Customer Testimonials – Roof Leak Repair Expert
“Sal was an absolute legend. We initially hired another roofer to fix the serious leak we had, which was causing damage in our kitchen. The other roofer came once, then refused to try and fix it any further, even though the leak had gotten worse. Called Sal and within 24 hours he had inspected and thoroughly diagnosed and fixed the problem. Highly recommend.”

“My experience with Sal from Kangaroof was excellent! My roof has now been tested by the recent heavy rain and – not a drip! – Thanks Sal. My roof is complicated, and previous roofers had failed to fix the leaks. We had to wait a while initially, because Sal was very busy after the heavy rain earlier in the year. But he kept in touch regularly – it was worth the wait. His work was professional, careful and methodical and I have no hesitation in recommending Kangaroof.”
Mike Alexander
HORNSBY HEIGHTS
“Sal was very impressive from his level of knowledge and advice to the actual quality of work and materials used. I would happily recommend Sal to anyone needing any sort of roofing work done. Our work was specifically to track down leaks and fix them. Sal did a thorough report including photographs from both before and afterwards to ensure we could see the issues and how his work had resolved the problems we had.”
Jane Ordon
WILLOUGHBY
“We had 5 other companies attempt to fix our roof and only Sal resolved our leaking roof issues. He was upfront and honest from the beginning and was very thorough during the whole process. I highly recommend his services 100%. Thanks Sal!”

“Going on his website reviews we expected big things of Sal and he did not disappoint! He assessed our leak efficiently and explained what he needed to do with a tricky little bit of roof to not only solve the current problem but to avert some likely future damage. He fitted our job in sooner than promised and provided photos and clear explanations of everything he did (which was exactly as quoted with a small freebie thrown in). Most importantly, we left it a while to write a review so we could confirm he has solved our problem and several thunderstorms later it’s thumbs up. Sal’s a lovely guy. 10 out of 10, we would use Kangaroof again if needed.”

“Absolute LEGEND!
He came, he saw, he fixed.
After 4 years, 3 builders and countless roof repair companies who couldn’t solve my leaking roof problem, I stumbled upon Sal!
We’d been having a mysterious ceiling water leak that would occur on and off during storms for at least a few years. Some storms had it leaking like a tap, other storms had it leaking like a drip. Builders and roof repair guys were stumped and no one could pinpoint the reason for the adhoc leaks. By then we were on the verge of putting it down to a poltergeist!!
Sal was a random google search that turned out to be heavenly. An absolute professional and it helped to have his background knowledge on building construction.
He came and took an hour or so to survey our roof on a fine sunny day. He was confident he found the source of the problem. Surprise surprise we haven’t had a leaky roof in 7 months since Sal diagnosed our roof problem despite Sydney experiencing some major storm activity this year.
I can’t recommend him enough.
Professional, friendly and an absolute legend. He got the job done when countless others couldn’t.”

“This is the 2nd time I have used Kangaroof. My huge mistake was to use someone else in between when I couldn’t get them in time. First time they solved a roof problem in mins on my 100 yr old tile roof that I had used ‘specialist’ roofers for over 10 yrs + 9 plumber visits – no-one had a clue. He could see immediately the problem & fixed it. I couldn’t believe that 4 other professionals couldn’t see something that made perfect sense to me.
Then I needed a new Kliplock roof 2 yrs ago. Got someone else to do it. TOTAL nightmare. Many roof leaks for first time ever, terrible leaks. They ‘fixed’ them twice & still leaking. That is roof hell and so stressful. Even my good builder couldn’t work out the leaks & he is really good.
I am very thorough and even I could see some of the problems but no idea how to fix once they’d been built into the new roof (by the bad so called expert roofer).
Then I rang Sal again to ask him PLEASE to come. Best choice in 2yrs.
He is very smart, could have done any career at all. Great brain, great diagnostician, problem solver & highly professional & talented.
He seriously, intelligently & methodically worked out what he thought it was, the numerous faults & weak points & knew how to make various pieces of custom flashing and angles to fix my new roof nightmare. He did temp fix to test, it worked. Heavy rain no problems. WHEW!!!
Then I accepted his quote, he came, he installed his awesome flashing and custom made solutions to my sad new roof that had at least 6 major faults that were always going to lead to leaks again & again.
My only hesitation in writing this glowing review is if he gets too busy to come whenever I might need him for my other house roof. Do yourself a favour. If you want a roof done well or to fix a nightmare some other roofer has caused you – ring Kangaroof. And he is a very nice man as well. 10/10. Wonderful to find a wonderful professional who really cares in this day & age. Thankyou Kangaroof”

Frequently Asked Questions
Most leak repairs are completed within 1-3 days of inspection. Emergency temporary repairs can often be done same-day to stop active leaking.
Absolutely. We provide detailed photo documentation and reports to support your insurance claim for storm damage or sudden leak events.
We can perform temporary repairs in most weather conditions. Permanent repairs requiring sealants or bonding may need to wait for dry conditions.
If a leak returns in the area we’ve repaired, we’ll come back and make it right. We stand behind our workmanship.
After our inspection, we’ll give you honest advice. If your roof has many years left and only needs localised repairs, we’ll tell you. If it’s near end-of-life, we’ll explain why replacement makes more sense.
Water can enter through a tiny crack, open sheet lap, or degraded washer seal and travel several meters along internal rafters, insulation, or sarking before dropping onto your ceiling. We combine internal ceiling cavity audits, structural visual checks, and controlled spray testing to trace the water path back to its exact point of entry.
Our diagnostic leak detection fee is $110. If you decide to proceed with the recommended repairs through Kangaroof, that entire $110 fee is credited directly toward your total repair costs.
Yes, it is best if someone is on-site. We often need access inside your home to inspect the ceiling cavity, check plasterboard moisture levels, and trace internal water stains directly beneath the roof structure.
No. Our diagnostic methods are entirely non-invasive. We isolate leak points using visual inspections, moisture auditing, and controlled water testing without cutting holes or causing damage to your property.
