If you’re wondering how to avoid being ripped off by dodgy roofers in Sydney, the short answer is this: never agree to work on the spot, always get written quotes from at least three licensed local trades, verify their NSW contractor licence on the Service NSW website, and steer clear of anyone demanding large cash deposits upfront. Sydney’s roofing trade has plenty of honest professionals, but a small group of opportunists give the industry a bad name, and they’re particularly active after storms, during long dry spells, and around older suburbs where weathered tiles are common.
Here’s what to watch out for, and how to find a roofer who actually does the job properly.
The Storm Chaser Knock
After a big southerly buster or hailstorm rolls through Sydney, expect strangers in unmarked utes to start knocking on doors. They’ll claim they were “working on a neighbour’s roof” and spotted damage on yours from the street. Sometimes they offer a free inspection, climb up, and come down with photos of “damage” that wasn’t there before they got up there.
Real local roofers don’t door-knock after storms. They’re booked solid handling calls from existing customers. If someone shows up unannounced offering urgent repairs, politely decline and ring a roofer you’ve researched yourself.
Quick tip: If you suspect storm damage, take photos from the ground first, then book an inspection with a trusted local like the team at Tomkat Roofing who can give you an honest assessment rather than a sales pitch.
The “Cash Only, Today Only” Pressure Sale
This one catches a lot of homeowners off guard. The roofer quotes a price, then says they can drop it significantly if you pay cash today because they “happen to have leftover materials from another job nearby.” The pressure is intense, and the deal sounds great.
It almost never is. Legitimate roofers don’t carry around extra tiles, sheets, or flashing hoping to flick them off cheap. What you usually get is substandard materials, no tax invoice, no warranty, and absolutely no recourse when the leak starts six months later. Australian Consumer Law gives you cooling-off periods on most contracts signed at home, which is exactly why scammers push for instant cash.

Inflated Insurance Claims
Some operators target homeowners with insurance cover, promising to “handle everything” with your insurer. The catch is they inflate the damage assessment, sometimes by damaging more of your roof to justify a bigger claim, then pocket the difference.
This is fraud, and you can end up wearing the consequences. Insurers are increasingly investigating suspicious claims, and if they prove collusion, your policy gets cancelled and future cover becomes hard to find. Always get an independent assessment before submitting a claim, and use a roofer who deals directly with you, not one who insists on dealing with your insurer behind closed doors.
The Disappearing Deposit
You pay 50% upfront for materials. The roofer comes, drops off a few pallets of tiles, then vanishes. Calls go to voicemail. The mobile number stops working. The ute that was parked out the front is nowhere to be seen.
This scam works because homeowners feel reassured when materials actually arrive. The truth is those tiles might be worth a fraction of your deposit, and chasing the operator through the courts is expensive and slow. Reputable Sydney roofers ask for a small deposit (usually 10% or less) and bill progressively as work is completed.
The Phantom Licence
NSW law requires roofers doing work over $5,000 to hold a contractor licence. Scammers know most homeowners never check, so they print a licence number on the quote that either belongs to someone else, has expired, or was simply made up.

Verifying a licence takes two minutes. Go to the Service NSW website, search the licence number, and confirm the name matches your quote. While you’re at it, check they hold roof tiling, roof plumbing, or roof slating endorsements depending on the work being done.
The “Found More Damage” Mid-Job Surprise
You agreed to a $4,000 repair. Halfway through, the roofer climbs down looking grim and announces they’ve found rotten battens, asbestos, water damage to the rafters, or some other dramatic discovery. The new quote is $15,000, and they’ve already pulled half your roof apart.
Some of these discoveries are genuine. Plenty are not. The way to protect yourself is to insist on photographic evidence of anything additional, the right to get a second opinion before approving extra work, and a written variation order before they touch anything new. Honest roofers expect this and will happily provide it.

Most reputable Sydney roofers offer free inspections for re-roofing quotes. Detailed reports with thermal imaging or structural assessments typically range from $250 to $600.
Do I need three quotes for roof repairs?
For anything over a couple of thousand dollars, yes. Three written quotes give you a realistic price range and help you spot outliers on either end.
