When you have a roof leak in Sydney, time is critical. Every day of delay means more damage to your ceiling, insulation, and home structure. But here’s the problem most homeowners face: finding the exact source of a leak is far more complex than most people realise.
At Kangaroof, we’ve spent over 20 years perfecting the art and science of roof leak detection across Sydney. We don’t rely on fancy equipment that can give false readings. Instead, we use decades of hands-on experience, systematic investigation techniques, and proven water testing methods to pinpoint exactly where your leak is coming from – every single time.
Our track record speaks for itself: We’ve never failed to find a leak. Not once in 20 years.
Once we find your leak, our expert team provides fast, permanent Roof Leak Repair Sydney – often completing repairs within 1-3 days. Your detection fee is fully credited toward repair costs, so you only pay for fixing the problem.
Why Professional Leak Detection Saves You Money
Many Sydney homeowners try DIY leak detection or hire roofers who make educated guesses about leak sources. The result? Unnecessary repairs to the wrong areas, wasted money, and leaks that keep coming back.
Here’s what makes our approach different:
- No guesswork – We systematically investigate until we find the exact source
- No expensive equipment charges – Our 20 years of experience is all we need
- No false positives – Water testing confirms the leak source before we recommend repairs
- Fix it once, fix it right – When we identify the problem, the repair actually solves it
Our leak detection fee is credited toward your repair when you proceed with us, so you’re not paying twice.
How We Find Leaks That Others Miss
Step 1: Understanding Your Leak Pattern | Step 2: Visual Roof Inspection | Step 3: Strategic Tile or Sheet Removal | Step 4: Water Testing – The Final Proof |Step 5: Comprehensive Reporting
Our Proven 20-Year Methodology
Unlike companies that rely on thermal imaging cameras or moisture meters (which can give misleading readings), we use a systematic, experience-based approach that’s proven to work:
Step 1: Understanding Your Leak Pattern
We start by asking detailed questions:
- When does it leak? (During rain, after rain, heavy rain only?)
- Where do you see water inside? (One spot or multiple?)
- Has it gotten worse over time?
- Have you had any recent work done on the roof?
This information tells us exactly where to focus our investigation.
Step 2: Visual Roof Inspection
We thoroughly inspect your roof from the outside, looking for:
- Damaged, cracked, or missing roof tiles or metal sheets
- Worn or deteriorated flashing around chimneys, skylights, and walls
- Valley issues where two roof planes meet
- Ridge cap problems
- Box gutter blockages or deterioration
- Sarking (roof membrane) failures visible from above
But here’s the key: We don’t just look at the obvious spots. After 20 years, we know the hidden areas where leaks commonly originate – the spots inexperienced roofers miss.
Step 3: Strategic Tile or Sheet Removal
When necessary, we carefully remove specific roof tiles or metal roof sheets in strategic locations. This lets us:
- Inspect the sarking (roof membrane) underneath
- Check the condition of battens and roof structure
- Identify water stain patterns that reveal the leak path
- See damage that’s completely hidden from above
We know exactly which tiles to remove based on where your internal leak appears and our understanding of how water travels under roofing materials.
Step 4: Water Testing – The Final Proof
This is the step that separates professionals from guessers. We conduct controlled water tests to confirm the exact leak source:
- We use a hose to simulate rain on specific areas of your roof
- You (or we) monitor inside to see when and where water appears
- We systematically test different sections until we pinpoint the exact entry point
- This eliminates guesswork and confirms our findings before any repair work begins
This is why we’ve never failed to find a leak. We don’t stop investigating until we have definitive proof of the source.
Step 5: Comprehensive Reporting
Once we’ve identified your leak, we:
- Show you photos of the problem area
- Explain exactly what’s causing the leak and why
- Provide a detailed, fair quote for repairs
- Answer all your questions about the repair process
- Discuss timing and what to expect
No pressure, no upselling – just honest information so you can make an informed decision.
What Happens After Detection?
Once we’ve identified your leak, you have two options:
- Proceed with repairs through Kangaroof – Your $110-$220 detection fee is fully credited toward your repair cost, and we guarantee our work. Most leak repairs are completed within 1-3 days. Learn more about our roof leak repair services →
- Take our findings elsewhere – You’re welcome to use another contractor. We provide detailed documentation and photos of exactly what needs repair.
Most customers choose to proceed with us because we’ve already demonstrated our expertise and understanding of their specific problem.
Why Kangaroof Doesn’t Use Thermal Cameras or Moisture Meters
You might wonder why we don’t use high-tech leak detection equipment when other companies advertise these tools. Here’s the honest answer:
Thermal Imaging Cameras Show Temperature Differences, Not Leak Sources
Thermal cameras detect heat variations. They’ll show you where water has caused cooling – but that’s often metres away from where water actually entered your roof.
Example: A thermal camera might show a cold spot near your skylight. But the actual leak could be at a valley 3 metres away, with water traveling along battens before appearing at the skylight area.
Result? You pay to repair the wrong spot.
Moisture Meters Only Confirm What You Already Know: It’s Wet
Moisture meters tell you there’s dampness in your ceiling – which you already knew because you saw the water stain or drip. They don’t tell you where the water entered your roof.
What Actually Works:
✓ 20 years of experience knowing where leaks typically originate
✓ Understanding water flow patterns in different roof types
✓ Strategic investigation removing the right tiles to see underneath
✓ Water testing to prove the source before recommending repairs
The Equipment We DO Use:
- Our eyes and decades of pattern recognition
- Ladders and safety equipment
- A garden hose for controlled water testing
- Camera for documentation
- Our experience-trained instinct
You Save Money: We don’t pass on expensive equipment costs, and we don’t repair the wrong spots based on misleading readings.
That’s why we’ve never failed to find a leak in 20 years.
Common Types of Roof Leaks in Sydney
Valley Leaks | Chimney Leaks | Skylight Leaks | Flashing Failures | Ridge Cap Leaks | Box Gutter Leaks | Broken or Cracked Roof Tiles | Metal Roofing Leaks | Sarking Failures
Over 20 years, we’ve encountered virtually every type of roof leak imaginable across Sydney homes. Here are the most common culprits:
Valley Leaks
Roof valleys (where two roof planes meet) are one of the most common leak sources in Sydney. Problems occur when:
- Valley metal corrodes or develops holes
- Valley flashing isn’t installed correctly
- Debris buildup causes water to overflow valley edges
- Valley metal wasn’t overlapped properly during installation
Water that enters at a valley often travels along battens before appearing inside your home – sometimes metres away from the actual entry point. This is why inexperienced roofers often repair the wrong spot.
Learn more about valley leak repairs →
Chimney Leaks
Chimneys are notorious for causing roof leaks, but the leak source isn’t always obvious:
- Flashing around the chimney base deteriorates or pulls away
- Mortar between bricks cracks and allows water entry
- Chimney caps are missing or damaged
- Counter-flashing (the upper layer of chimney flashing) fails
Many homeowners assume it’s a roof problem when it’s actually a chimney issue, or vice versa. Our systematic approach identifies the real culprit.
Learn more about chimney leak repairs →
Skylight Leaks
Skylights can leak from several sources:
- Flashing around the skylight perimeter
- The skylight seal or gasket itself
- Skylight mounting issues
- Condensation inside the skylight (not actually a leak)
We determine whether your skylight needs flashing repair, seal replacement, or complete skylight replacement.
Learn more about skylight leak repairs →
Flashing Failures
Flashing is the metal that creates a waterproof seal between your roof and vertical surfaces (walls, chimneys, vents). When flashing deteriorates or was poorly installed, leaks develop.
Common flashing leak locations:
- Wall flashings where roof meets house wall
- Step flashing along dormers
- Apron flashing at roof penetrations
- Vent pipe boots and flashings
Learn more about flashing repairs →
Ridge Cap Leaks
The ridge cap runs along the peak of your roof. Over time:
- Mortar bedding under ridge tiles deteriorates
- Metal ridge capping develops gaps or corrosion
- Flexible pointing fails and cracks
- Storm damage dislodges ridge caps
Ridge cap leaks often appear as ceiling stains along the highest point of your ceiling.
Box Gutter Leaks
Box gutters (internal gutters built into the roof structure) are common in older Sydney homes and can cause significant damage when they fail:
- Rust holes develop in metal box gutters
- Overflow occurs during heavy rain if gutters are undersized
- Outlet blockages cause water to back up
- Joints between gutter sections fail
Box gutter leaks can be particularly destructive because large volumes of water can enter quickly. Lean more about box gutter leak repairs →
Broken or Cracked Roof Tiles
Individual tile damage allows direct water entry:
- Tiles crack from foot traffic or falling branches
- Tiles break during storms
- Nail holes enlarge over time
- Corner chips allow water to bypass the tile overlap
While broken tiles seem like an obvious leak source, water often travels under multiple tiles before entering your ceiling, making the exact entry point hard to pinpoint.
Metal Roofing Leaks
Metal roofs develop leaks from:
- Screw washer failures (rubber washers deteriorate)
- Corroded holes in sheet metal
- Poorly sealed overlaps between sheets
- Expansion and contraction creating gaps
- Rust damage, especially in coastal Sydney areas
Learn more about metal roofing repairs →
Sarking Failures
Sarking (the waterproof membrane under your roof tiles or metal) is your roof’s second line of defence. When it fails:
- Tears develop from age or installation damage
- Condensation causes deterioration
- UV exposure (where tiles are missing) breaks it down
- Incorrect installation leaves gaps
Sarking failure often causes multiple leak points or widespread dampness rather than a single drip.
Why Sydney Roofs Develop Leaks
Coastal Homes | Inland Sydney | Storm Damage | Age-Related Deterioration
Understanding why leaks develop helps explain why professional detection is so valuable:
Sydney’s Unique Weather Challenges
Coastal Homes:
- Salt air accelerates corrosion of metal flashings and roof sheets
- Stronger winds drive rain into gaps that inland homes don’t experience
- Higher humidity means condensation issues
Inland Sydney:
- Extreme temperature variations cause expansion/contraction stress
- Storm intensity can overwhelm guttering and valleys
- Bushfire risk areas have ember attack points
Storm Damage: Sydney’s severe storm seasons cause:
- Direct hail damage to tiles and metal roofing
- Tree branches breaking tiles or puncturing metal
- Wind uplift loosening flashings and ridge caps
- Debris blocking valleys and gutters causing overflow
Age-Related Deterioration
Different Sydney housing eras have characteristic leak patterns:
Pre-1960s Homes:
- Original terra cotta tiles may be cracked or worn
- Sarking often absent or deteriorated
- Box gutters common (and prone to failure)
- Chimney flashings original and failing
1960s-1990s Homes:
- Concrete tiles may be delaminating
- Original roof penetrations (vents, skylights) reaching end of life
- First-generation sarking breaking down
- Valley metal corroding through
2000s-Present:
- Screw-fixed metal roofing with deteriorating rubber washers
- Expansion issues in Colorbond roofing
- Improperly installed flashings from rushed construction
Real Stories: Complex Leaks We’ve Solved
The “Three Roofers Couldn’t Fix It” Leak – Eastwood
A homeowner in Eastwood called us after three different roofers had attempted repairs, each charging $500-$800, and the leak continued. They’d replaced tiles, resealed the valley, and even installed new sarking in one section.
Our investigation revealed: The actual leak source was 4 metres uphill from where the water appeared inside. A tiny crack in the valley metal was allowing water under the sarking, where it traveled along the batten before dripping through.
We removed strategic tiles to trace the water path, conducted water testing to confirm, then repaired the actual leak point. Total cost: Less than what they’d already wasted on wrong repairs. The leak never returned.
The Intermittent Storm Leak – Northern Beaches
This homeowner’s leak only appeared during heavy storms with easterly winds. Multiple roofers said “your roof looks fine” and suggested it might be a plumbing issue.
Our systematic approach: We knew easterly storms drive rain horizontally in coastal areas. We focused on vertical surfaces and flashings on the east-facing side. Testing revealed wind-driven rain was entering behind poorly installed wall flashing that looked fine in normal conditions.
Our flashing repair solved a 3-year mystery. Learn more about our flashing repairs →
The Skylight That Wasn’t – Hills District
A family was getting quotes for expensive skylight replacement after water appeared around their skylight during rain. Quotes ranged from $1,800-$3,500.
Our detection process revealed: The skylight was actually fine. The leak was from deteriorated chimney flashing 2 metres away – water was traveling horizontally before dripping near the skylight.
We repaired the chimney flashing for under $600. The “skylight leak” disappeared immediately.
The Multiple Leak Points – Inner West
A Leichhardt homeowner had water appearing in three different bedrooms during rain. Previous roofers quoted $8,000+ for extensive sarking replacement under the entire roof.
Our investigation: Yes, the sarking had failed – but only in specific areas. We identified three separate entry points: a valley issue, a broken tile from overhanging tree branches, and one deteriorated ridge cap. By targeting the actual problems rather than replacing the entire roof membrane, we solved all three leaks for under $2,000.
Strategic tile removal and water testing identified each source before any unnecessary work was done.

Why Professional Detection Saves Money
Consider the math:
DIY or Guesswork Approach:
- Repair attempt #1: $500-$800 (wrong spot)
- Repair attempt #2: $500-$800 (still wrong)
- Repair attempt #3: $500-$800 (maybe gets it)
- Total wasted on wrong repairs: $1,000-$2,400
- Total time with ongoing leak damage: Months
- Stress and frustration: Priceless
Professional Detection Approach:
- Detection fee: $110-$220 (fully credited when you proceed with our roof leak repairs)
- Correct repair first time: $440 – $2,200
- Total actual cost: Just the repair (detection credited)
- Leak fixed: First time, permanently
- Peace of mind: Immediate
Cost of Delaying Leak Detection
Every week you wait with an active leak:
- Ceiling damage worsens (requiring more expensive repairs)
- Insulation becomes saturated and needs replacement
- Structural timber can develop rot
- Mould and mildew develop health hazards
- Electrical systems may be compromised
- Resale value decreases if damage is visible
A $110-$220 investment in professional leak detection can save thousands in secondary damage repairs.
What Type of Leak Do You Have? Find Out in 30 Seconds
Question 1 of 5
Is water actively dripping from your ceiling right now?
Question 2 of 5
You see stains or marks on your ceiling. Do you know when the leak occurred?
Question 2 of 5
Is it dripping fast? (More than 1 drip per second)
Question 3 of 5
Does your leak happen every time it rains?
Question 4 of 5
Does it only leak during heavy rain or specific wind directions?
Question 5 of 5
Have you already tried repairs that didn't work?
🚨 EMERGENCY LEAK - Call Immediately
Your leak is causing active, ongoing damage right now.
Fast dripping means significant water is entering your home. Every hour of delay means more damage to ceilings, insulation, electrical systems, and structural timber.
What you should do RIGHT NOW:
- Place buckets under all drip points
- Turn off electricity to affected rooms if water is near lights or outlets
- Move valuables and furniture away from the leak
- Call us immediately for same-day emergency service
We can often provide temporary repairs immediately to stop further damage while you decide on permanent solutions.
⚠️ HIGH URGENCY - Call Within 24-48 Hours
Your leak needs professional attention quickly.
A consistent leak that happens every time it rains means you have a reliable leak source. Even if it's not actively dripping right now, the damage is progressing and will get much worse with the next rain.
Why this is urgent:
- Water damage compounds with each rain event
- Mould can develop within 24-48 hours of water exposure
- Ceiling materials weaken and may collapse if water-saturated
- Structural timber can begin rotting
Schedule your leak detection now before the next storm:
Remember: Your leak detection fee is fully credited toward repairs when you proceed with Kangaroof.
⚠️ HIGH URGENCY - You Need Professional Leak Detection
Previous roofers likely repaired the wrong spot.
This is exactly what we specialize in. When other roofers guess at the leak source and fail, we use our proven 20-year methodology to find the actual entry point.
Why repairs fail:
- Water travels along battens and sarking before appearing inside - often metres from the entry point
- Roofers repair where you see water, not where it's actually entering
- Without systematic water testing, it's just guesswork
Our approach is different: We systematically investigate, remove strategic tiles to see underneath, and conduct water testing to PROVE the source before recommending repairs.
We've never failed to find a leak in 20 years.
Stop wasting money on wrong repairs. Contact us for professional leak detection
Your detection fee is credited toward the correct repair. You only pay once, and the leak gets fixed properly.
📋 MEDIUM URGENCY - Schedule Within 1-2 Weeks
Your leak should be addressed soon, but you have a bit of time to schedule.
Intermittent leaks (only during heavy rain or specific conditions) typically indicate wind-driven rain entering through flashings or vertical surfaces. These leaks get worse over time as gaps widen from thermal expansion, wind stress, and ongoing deterioration.
Why you shouldn't delay too long:
- Even intermittent leaks cause hidden damage you can't see
- Insulation absorbs water and loses effectiveness
- Timber stays damp between leaks, promoting rot
- Small gaps become larger gaps during Sydney's storm season
Smart move getting professional detection first: You'll avoid wasting money on guesswork repairs that don't solve the problem.
Book your leak detection before Sydney's next storm system. We offer same-day or next-day scheduling in most cases.
✓ PREVENTATIVE - No Active Leak Detected
Great! You're being proactive.
Even without visible signs of leaking, it's smart to consider a roof inspection if:
- Your roof is over 15 years old
- You've recently had severe storms
- You've noticed damaged or missing tiles from the ground
- You're planning to sell and want peace of mind
- You've had leaks in the past
Preventative inspections catch small problems before they become expensive leaks.
Common issues we find during preventative inspections:
- Cracked or deteriorating valley metal (future leak risk)
- Loose or damaged flashing around chimneys and skylights
- Worn ridge caps that need rebedding
- Minor tile damage that will worsen
- Blocked or deteriorating gutters
Or call us for a preventative roof inspection: 0403 944 466
Fixing small issues now costs hundreds. Waiting until they become leaks costs thousands.
Frequently Asked Questions About Roof Leak Detection
Experience is everything. After 20 years and thousands of leak investigations, we’ve developed an instinct for where leaks originate. We know that water rarely enters where it appears inside – it travels along battens, sarking, and roof structure before dripping through your ceiling.
We also use systematic water testing rather than guesswork. We don’t recommend repairs until we’ve confirmed the exact source.
These tools can give false readings:
- Thermal cameras show temperature differences, not necessarily leak sources
- Moisture meters detect dampness, but can’t tell you where water entered
- Both can lead to repairing the wrong areas
Our experience-based approach, combined with visual inspection and water testing, is more reliable and accurate. Plus, we don’t pass on expensive equipment costs to you.
In our 20 years of service, we’ve never failed to find a leak source. Some leaks are more complex and require more investigation time, but by systematically eliminating possibilities and conducting thorough water testing, we always identify the entry point.
Occasionally, a home may have multiple leak sources that were masked by each other, but we find them all.
This is common and actually gives us valuable information. The conditions when your leak appears tells us:
- Wind-driven rain leaks indicate wall flashings or vertical surfaces
- Heavy-rain-only leaks suggest overflow issues or capacity problems
- Leaks after rain suggest pooling water finding slow entry points
We can simulate these conditions during testing, or schedule our investigation during appropriate weather if needed.
We take great care when inspecting. When we need to remove tiles or metal sheets, we:
- Choose strategic locations that give us the information we need
- Remove the minimum necessary
- Properly replace and reseal everything we remove
- Leave your roof in the same (or better) condition than we found it
All our work is fully insured, and we’ve never caused damage during leak detection in 20 years.
Most leak detections take 1-2 hours, though complex cases might require longer. Factors include:
- Size and complexity of your roof
- Number of potential leak sources
- Whether water testing is required
- Accessibility challenges
We’ll give you an estimated timeframe when we schedule your inspection.
We provide:
- Photos showing the exact problem
- Clear explanation of what needs repair
- Detailed, itemised quote for the repair work
- Our recommendations for timing and urgency
- Answers to all your questions
You’re under no obligation to proceed with repairs through us, but your detection fee is credited if you do. Most customers proceed because we’ve already proven we understand their specific problem.
It’s helpful to have you or someone home who can:
- Show us exactly where water appears inside
- Monitor during water testing
- Ask questions about our findings
- Receive the detailed report and quote
If you can’t be home, we can work with photos you provide and follow up with a phone call, though we prefer to communicate findings in person.
Often, yes! If:
- We have the materials on hand or can source them quickly
- The repair is straightforward
- Weather conditions are suitable
- You want to proceed immediately
For more complex repairs, we’ll schedule a separate visit with all necessary materials and equipment. Emergency temporary repairs can usually be done immediately to prevent further damage.
If there’s a delay between detection and repair, and rain is forecast, we can often provide temporary protection like tarping or sealant to minimise damage until the permanent repair is completed.
How much will the repair cost?
Repair costs vary widely depending on:
- The specific problem identified
- Materials required
- Extent of damage
- Accessibility
- Whether scaffolding is needed
Typical repair ranges:
- Simple tile or flashing repairs: $440-$880
- Valley repairs: $440-$1500
- Chimney flashing repairs: $550-$2200
- Skylight repairs: $440-$1800
- More extensive repairs: $1500-$3000
We provide detailed, itemised quotes with no hidden fees. Remember, your detection fee is credited toward your repair cost.
Absolutely. All our repair work is guaranteed. If a leak persists after our repair (which is extraordinarily rare), we return and make it right at no additional cost.
Yes. We provide detailed documentation including:
- Photos of the damage and leak source
- Description of the problem
- Itemised repair quote
- Professional assessment of cause (storm damage, age-related failure, etc.)
Many of our customers successfully claim roof leak repairs through their insurance, especially when storm damage is involved.
We investigate until we find all leak sources. Sometimes what appears as multiple leaks is actually one source with water traveling to several ceiling spots. Other times, there genuinely are multiple entry points.
Our systematic approach identifies all problems, and we prioritise repairs based on urgency and your budget if needed.
A: We provide complete leak solutions. Our roof leak repair service fixes the exact problem we’ve identified – typically within 1-3 days of detection. Your detection fee is fully credited toward repair costs, so you’re essentially getting free leak detection when you proceed with repairs. Most customers choose to have us complete the repair because we’ve already proven we understand their specific problem and can fix it permanently.

Customer Testimonials – Leak Detection Specialists
“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.”
Paul Coles
MARRICKVILLE
“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!”
Geraldine
TURRAMURRA
“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.”
Christine Binskin
NORTH ROCKS
“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.”
Gloria Howard
LINDFIELD
“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”

“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.”
