How to Spot Roofing Scams and Dodgy Contractors in Perth

6 min read

Every year we hear from Perth homeowners who’ve been burned by dodgy roof contractors - jobs abandoned halfway through, cheap paint failing within months, or “inspectors” who knock on the door claiming urgent repairs are needed.

The roofing industry attracts its share of fly-by-night operators because roof work is hard for homeowners to inspect and easy to cut corners on. Here’s how to protect yourself.

The Most Common Roofing Scams in Perth

The Door Knocker

Someone turns up uninvited claiming they were “working in the area” and noticed your roof needs urgent attention. They offer a special price because they have leftover materials or their crew is already nearby.

Why it’s a scam: Legitimate contractors don’t need to cold-call for work. They’re usually booked weeks in advance. The “special price” is either inflated from the start, or the work will be substandard.

The Storm Chaser

After a big storm, operators appear from nowhere offering emergency repairs. They want payment upfront, do a quick patch job, then disappear.

Why it’s a scam: Real emergency repair companies exist and are established in the area long before the storm hits. Storm chasers often aren’t licensed, don’t carry insurance, and won’t be around when the patch fails.

The Lowball Quote

A quote comes in dramatically lower than everyone else - sometimes half the price. The contractor asks for a large deposit upfront to “secure materials.”

Why it’s a scam: Either they’ll use cheap materials and skip critical preparation steps, or they’ll take the deposit and vanish. If a quote seems too good to be true, it is.

The Invisible Prep

The contractor offers roof painting at a reasonable price but skips the cleaning, repairs, and priming. They paint straight over a dirty, damaged roof. It looks great for a few months, then the paint peels off.

Why it’s a scam: Paint applied to a poorly prepared surface will fail. The full preparation - high-pressure cleaning, repairs, flexi-point, primer - is where most of the labour goes. Skipping it saves the contractor time and money at your expense.

Red Flags to Watch For

Before hiring:

• No fixed business address or just a mobile number
• No ABN or refuses to provide one
• Can’t show proof of insurance (public liability and workers’ compensation)
• No portfolio of completed work or references
• Pressures you to sign immediately or offers “today only” pricing
• Asks for more than 10-20% deposit upfront
• Won’t provide a written quote with detailed scope of work
• Has no online presence, reviews, or verifiable history

During the job:

• Different crew shows up than who quoted the job
• Skip the high-pressure clean or do a light hose-down instead
• Don’t do any repairs before painting
• Rush through the job in a day when a full restoration takes 3-5 days
• Can’t tell you what products they’re using or refuse to leave product data sheets

After the job:

• No completion photos or documentation
• Won’t provide a warranty in writing
• Disappear when you call about issues
• The paint starts chalking, peeling, or fading within 12-18 months

What a Legitimate Contractor Looks Like

A reputable roofing contractor in Perth will:

• Have a registered business with an ABN and a verifiable history
• Carry insurance - public liability (minimum $10 million) and workers’ compensation
• Provide a written quote that details every step: cleaning method, repairs, primer, coats of paint, product names, and warranty terms
• Be happy to show past work - photos, addresses you can drive past, Google reviews from real customers
• Give you time to decide - no pressure to sign on the spot
• Use branded, name-brand products and be able to tell you exactly what’s going on your roof
• Offer a workmanship warranty in writing separate from the manufacturer’s product warranty
• Be accredited by the paint manufacturer they use - this means the manufacturer has vetted their work quality

Questions to Ask Before You Sign

1. “Can I see your certificate of currency for public liability and workers’ comp?” - Any legitimate contractor will have this ready. If they hesitate, walk away.

2. “What products will you use, and can I have the data sheets?” - A professional knows exactly what they’re applying and is proud of the products they use.

3. “What does the preparation involve?” - The answer should include high-pressure cleaning, drying time, repairs to broken tiles/pointing/flashings, and a primer coat before the topcoats.

4. “How many coats of paint, and what’s the coverage rate?” - Manufacturer specifications require minimum coverage rates. Stretching paint too thin is a common corner-cutting tactic.

5. “What’s your warranty, and is it in writing?” - Verbal warranties are worthless. Get it on paper with specific terms.

6. “Are you an accredited applicator for the products you use?” - Accreditation means the manufacturer trusts the contractor’s workmanship enough to back it with their warranty program.

7. “Can I see three recent jobs in my area?” - A busy, reputable contractor will have plenty of examples.

What to Do If You’ve Been Scammed

If you’ve already paid for substandard work:

1. Document everything - photos of the work, copies of any quotes or receipts, text messages, emails
2. Contact Consumer Protection WA (Department of Mines, Industry Regulation and Safety) - they handle complaints about building and trade services
3. Leave honest reviews on Google and social media to warn others
4. Contact your bank if you paid by card and the contractor has disappeared - you may be able to dispute the charge
5. Get an independent assessment - another contractor can document the defects and provide a report for your complaint

The Real Cost of Cheap Roof Work

A proper roof restoration in Perth costs what it costs because the materials, labour, and expertise aren’t optional. When someone offers the same job for half the price, they’re not more efficient - they’re cutting corners you can’t see from the ground.

A failed roof coating that needs to be stripped and redone costs more than doing it right the first time. And a paint failure voids the manufacturer’s warranty entirely, because the product was applied outside their specifications.

The Bottom Line

The best protection is a combination of research, written documentation, and trusting your instincts. Get at least two or three quotes, check reviews, verify insurance, and don’t let anyone pressure you into a decision on the spot.
