Choosing a Roofer in Perth: Licences, Quotes and Red Flags

Your roof is one of the most expensive and important parts of your home. It has to cope with Perth's hot, UV-heavy summers, sudden winter storms and, if you live in Rockingham, Safety Bay, Baldivis or Waikiki, salt-laden coastal air that speeds up corrosion. A good roofer protects your investment for decades. A poor one can leave you with leaks, voided warranties and expensive rework. This guide covers what to check before you hire, how to compare quotes properly, and which warning signs to take seriously in 2026.

Understanding Roofing Licences and Registration in Western Australia

Roofing in WA sits across a few regulatory areas, and which one applies depends on the work. Rules and dollar thresholds can change, so confirm current requirements with the Building and Energy division of the Department of Mines, Industry Regulation and Safety (DMIRS) before signing anything.

Building contractor registration

Under the Building Services (Registration) Act 2011, a contractor carrying out residential building work above the prescribed value (currently $20,000 for most work) generally needs to be a registered building contractor. Full roof replacements often reach this threshold. Smaller repairs may fall below it, but that is no reason to skip your checks. Ask for the contractor's registration number and verify it through the Building and Energy public register.

Plumbing licences for gutters, downpipes and flashings

Much roof drainage work, including installing gutters, downpipes and stormwater connections, counts as plumbing work in Western Australia. This work should be done by a licensed plumber, so ask who will be doing it. Some roofing companies employ licensed plumbers directly. Others subcontract the work. Either is fine as long as the person doing the job holds the correct licence. You can check licences through the Plumbers Licensing Board.

Asbestos roofing: a special case

Many Perth homes built before the late 1980s have asbestos cement roof sheeting, and some later ones still contain asbestos products. In WA, removing more than 10 square metres of bonded asbestos https://emilianoqaou401.fotosdefrases.com/how-to-handle-a-roof-insurance-claim-after-a-perth-storm material requires a licensed asbestos removalist, and the work must follow WorkSafe requirements. If your roof might contain asbestos, do not let a general roofer simply "pull it off". Ask for testing first, and check that anyone handling removal holds the right class of licence.

Building permits and council requirements

Some roof work needs a building permit, particularly if you are changing the structure, roof pitch or materials in a way that affects the building. Like-for-like replacement may have different requirements. Your roofer should know the rules, but the responsibility ultimately rests with you as the owner. If you are unsure, contact the City of Rockingham or your local council before work starts.

Insurance and Protection You Should Confirm

Licences show a contractor is allowed to do the work. Insurance protects you when something goes wrong. Ask to see current certificates for:

Public liability insurance: covers damage to your property or neighbouring property caused by the work, such as a dropped tile or a storm hitting while the roof is exposed.
Workers' compensation insurance: covers workers injured on your site. Roofing involves working at heights, so this is essential.
Home indemnity (domestic building) insurance: in WA, this is generally required for residential building work above the prescribed value. It protects you if the builder dies, disappears or becomes insolvent. Ask for the certificate before paying a deposit.

Do not rely on a verbal promise. A reputable roofer will provide certificates without hesitation, and you can phone the insurer to confirm the policy is current.

How to Get and Compare Roofing Quotes

Aim for at least three written quotes. Comparing them is easier when each contractor has quoted on the same scope, so give every roofer the same information and let them inspect the roof in person. Be wary of anyone who quotes a full replacement without going up on the roof or inspecting the roof space.

What a good quote includes

A detailed quote makes it clear what you are paying for. Look for:

The contractor's business name, ABN, and registration or licence numbers
The exact materials, including brand, profile, thickness and colour (for example, Colorbond steel and its base metal thickness, or the tile manufacturer and range)
Whether the product suits coastal conditions, which matters in Rockingham and other suburbs near the water
Removal and disposal of old materials, including how asbestos will be handled if relevant
Details of battens, sarking or anticondensation blanket, insulation, ridge capping, valleys, flashings and fixings
Gutter and downpipe work, and who will carry it out
Start and completion dates, and what happens if bad weather causes delays
Payment schedule, GST, and warranty details for both workmanship and materials

Compare more than price

The cheapest quote is rarely the best value. A low price often means thinner steel, fewer fixings, no sarking, reused battens, or skipped steps such as re-bedding and repointing ridge tiles. Two quotes that look similar in total can describe very different jobs. Ask each roofer to explain any differences, and check the materials against the manufacturer's specifications and warranty conditions.

Know your contract rights

In WA, the Home Building Contracts Act 1991 sets requirements for domestic building contracts above a certain value, including that the contract be in writing and contain specific information. It also limits the deposit a builder can ask for. Check the current rules with Building and Energy, and never agree to a deposit well above what the law allows.

Red Flags to Watch For

Most roofers in Perth are honest tradespeople, but a few warning signs are worth taking seriously.

Unsolicited door-knocking or flyers claiming your roof is "dangerous". Storm-chasing and pressure sales do occur after bad weather. Get an independent opinion before agreeing to anything.
Pressure to sign on the spot or "today only" discounts. A genuine quote will still be valid after a few days.
Large upfront deposits or cash-only payment. Excessive deposits, and requests to pay in cash with no receipt or invoice, are common in complaints.
No written quote or contract, or a vague one that lists only a total price.
Reluctance to show registration, licences or insurance, or details that cannot be verified on the public registers.
No fixed address, only a mobile number, and no verifiable reviews or past work you can inspect.
Suggesting you do not need a permit or that asbestos "is fine to break up". This can create legal and health risks for you.
A quote far below the others. Underquoting is often followed by variations, shortcuts or abandoned jobs.

Questions to Ask Before You Hire

A short conversation can reveal a lot. Ask how long the business has been trading, whether the crew are employees or subcontractors, and who will supervise the job day to day. Ask what happens if rain is forecast while the roof is open, how they protect your garden and driveway, and how they handle clean-up. Ask for recent local references, and if possible look at completed roofs in your area. Check online reviews across several platforms, and look at how the business responds to complaints as well as praise.

Choosing Materials for Rockingham and Coastal Perth

Local conditions should influence your choice. Near the coast, salt spray can shorten the life of unsuitable metal roofing and fixings, so ask about coastal-grade options, correct fasteners and manufacturer warranty conditions for your distance from the ocean. Terracotta and concrete tiles are common across Perth and perform well, but ridge capping, pointing and valley gutters often need maintenance before the tiles themselves fail. Light-coloured roofing can reduce heat absorption in summer, and good insulation and sarking improve comfort and energy efficiency. These matter more as electricity costs and heat extremes remain a concern into 2027 and beyond.

Before Work Begins and After It Finishes

Before the job starts, confirm the written contract, permit status if required, insurance certificates, start date and payment schedule. Keep copies of all documents together. Once the roof is finished, inspect the work with the roofer where possible, check that gutters drain properly, and ask for written warranties, product documentation and any compliance certificates. Pay the final instalment only when you are satisfied the work matches the contract.

If a dispute arises and you cannot resolve it directly, Building and Energy provides a complaint and dispute resolution service for building work, and the Plumbers Licensing Board handles plumbing matters. Acting early and keeping good records puts you in a much stronger position.

Final Thoughts

Choosing a roofer is about more than finding a good price. Check registration and licences, confirm insurance, compare detailed written quotes and pay attention to red flags. Taking a little time at the start helps ensure your roof withstands Perth's sun, wind and coastal conditions for many years. If you are unsure about any requirement, a quick call to Building and Energy or your local council can save a lot of trouble later.
