An Australian roofing business typically sells for 2x to 4x EBITDA. Commercial operations with maintenance agreements sit toward the upper end of that range; residential and storm-damage specialists sit closer to the lower end. The single biggest valuation driver isn’t turnover — it’s how predictable the revenue is and how much the business depends on the owner.
That’s the short version. The longer version is worth reading before you take any calls from buyers.
What Drives the 2x–4x Range
The spread isn’t arbitrary. It reflects the real difference in risk between types of roofing businesses.
At the lower end — 1.5x to 2.5x EBITDA — you’ll find owner-operators where the owner also quotes, supervises, and manages the key client relationships; storm damage and insurance restoration specialists where revenue spikes unpredictably with weather events; and new-build subcontractors dependent on one or two volume builders for most of their work.
At the upper end — 3.5x to 5x EBITDA — you’ll find roofing businesses with commercial maintenance agreements, operations with a permanent team and systems in place, and businesses with diversified revenue across residential, commercial, and roofing restoration.
Rule of thumb: A roofing business turning over $1.5M with strong margins and a maintenance contract book is worth considerably more than one turning over $3M on storm work and new construction alone. Revenue size matters far less than revenue predictability.
This is the same principle that applies across trade business valuations in Australia — buyers pay for certainty, not for last year’s best number.
Maintenance Contracts: Where the Real Value Lives
If there’s one thing that consistently adds value to a roofing business, it’s commercial maintenance agreements. Strata building managers, commercial property managers, shopping centres, industrial estates, aged care facilities — these clients create scheduled work that doesn’t depend on weather, insurance claims, or the builder approval queue.
A roofing business with $150K in annual recurring maintenance revenue — gutter clearing, re-bedding, roof inspections, preventive patching, Colorbond restoration work — is more valuable than a business with $300K in one-off residential jobs, even though the one-off business has higher turnover. The reason is simple: a buyer can underwrite predictable cash flow. They can’t underwrite “it might hail again.”
Buyers typically value a documented maintenance agreement book at 0.5x–1.5x the annual contract value as a premium over and above the EBITDA multiple. A $150K maintenance book with three-year agreements signed to the company entity could add $75K–$225K to your sale price on its own.
The critical word there is “entity.” Those agreements need to be with your company, not with you personally. A maintenance arrangement with a strata manager based on a phone relationship and a handshake is goodwill that walks out the door the day you do.
Storm Work and the Weather Discount
Roofing businesses that have grown on the back of storm seasons — hail damage in Perth and Brisbane, cyclone repairs across Queensland and WA, insurance claim work following major weather events — tend to attract lower multiples. Buyers aren’t being difficult; they’re being rational.
Storm revenue is lumpy. A $2M year off the back of a major hail event can be followed by a $900K year when the weather behaves. If your EBITDA is built on storm income, a sophisticated buyer will normalise your financials — stripping out exceptional weather-event years and looking at what the business earns in an average season. That normalised EBITDA is almost always lower than your peak-year figure, and it’s the normalised figure that gets multiplied.
I spoke with an owner in Perth’s southern suburbs a couple of years ago who had two genuinely strong years off the back of a significant storm event in WA. He came to the market expecting the price those peak earnings implied. Buyers weren’t moving. The issue wasn’t the business itself — it was solid — but no buyer was going to pay a 3.5x multiple on revenues that depended on another hail season arriving on cue. He eventually sold at a multiple based on his normalised three-year average. (He took it philosophically. He’d have done better if those good years had gone into building commercial contracts rather than just absorbing the windfall, but that’s easier to say sitting across the table than in the middle of a busy storm season.)
The lesson: if you’re growing on storm work, invest those margins into maintenance contracts. That transforms volatile income into the kind of predictable revenue buyers actually pay for.
Trade Licensing: The Complication Nobody Mentions Early Enough
In Western Australia, contractors performing roofing work require registration under the Building Services (Registration) Act — specifically, a Roof Plumber or Builder registration depending on the scope of work. In Queensland, relevant QBCC licences are required. In Victoria, it’s Building Practitioner registration through the VBA.
The complication when selling: these licences attach to individuals, not companies. Your buyer needs their own licence — or needs to retain a licensed supervisor as a condition of the deal.
This isn’t a deal-breaker in most transactions, but it narrows your buyer pool and affects deal structure. If you are the only licensed person in the business, you’ve created what buyers call a key person dependency baked directly into the regulatory structure. It affects price, transition period, and — in some cases — whether a buyer proceeds at all.
Rule of thumb: If your roofing licence is the only one in the business, it limits both who can buy you and what they’ll pay. Adding a second licensed supervisor or project manager is one of the highest-ROI moves you can make in the 12–18 months before going to market.
Who Buys Roofing Businesses in Australia?
Different buyers are attracted to different business profiles. Here’s who’s active in the market right now.
Consolidating roofing groups are the most active acquirers at the $1M–$5M revenue level. A mid-size roofing operation looking to expand into Perth metro, South-East Queensland, or regional WA will acquire a smaller operator to gain licensed staff, local client relationships, and established subcontractor networks. These buyers understand the trade and can absorb a business quickly. They’re also more willing to work around licensing requirements because they typically have licence holders on their own team.
Building and construction groups looking to bring roofing capability in-house acquire trade roofing businesses — particularly those with strong builder relationships and high-volume, multi-project pipelines. They want production capacity, not maintenance books.
PE-backed trade services platforms have been consolidating across plumbing, electrical, HVAC, and roofing over the past three to four years. They target businesses with $150K–$400K EBITDA, a management layer in place, and a team that will stay post-sale. These buyers structure deals with an upfront component and an earn-out tied to team retention and revenue targets. If your business is in this range, it’s worth understanding how these deals are structured before you take any call from a platform acquirer.
Individual buyers — experienced roofers or site managers stepping up from employee to owner — represent the traditional buyer at the sub-$2M revenue level. A senior roofer with 15 years on the tools, a contractor licence, and some savings wants to skip the startup phase. They’re hands-on, they understand the work, and they’re often the right cultural fit for smaller operations — particularly if you want a genuine transition and a buyer who’ll keep your team.
What Your Business Might Actually Be Worth
| Business Profile | EBITDA Multiple | Typical Goodwill Range |
|---|---|---|
| Owner-operator, residential re-roofing only | 1.5x–2.5x | $50K–$150K |
| 3–6 staff, mixed residential and commercial | 2x–3.5x | $150K–$400K |
| 6–12 staff, maintenance contracts, job management systems | 3x–4.5x | $350K–$900K |
| 12+ staff, commercial-led, manager-run | 4x–5x+ | $700K–$2M+ |
These are goodwill figures. Plant and equipment — vehicles, scaffolding, machinery, trailers — are valued separately. Buyers will inspect your fleet carefully; a van with 280,000km on the clock is a liability, not an asset.
The Financials Buyers Scrutinise
Before any conversation about multiples, buyers will want to understand your normalised EBITDA — your actual earning capacity once owner-specific costs are stripped out. This is where EBITDA add-backs matter.
Common add-backs in roofing businesses include: owner salary above what a hired manager would cost, personal vehicles run through the business (the company ute that doubles as the family’s weekend car), one-off equipment write-offs, and any non-recurring project costs.
The other thing buyers scrutinise: work in progress. Roofing businesses often carry significant WIP at any point in time — materials purchased, labour billed, but projects not yet invoiced. If your WIP isn’t tracked cleanly, buyers can’t accurately assess what you’re owed versus what you’ve earned. Messy WIP management signals a messy business. It’s one of the fastest ways to lose credibility in due diligence.
For industry EBITDA multiples across comparable trades, it’s worth understanding how roofing sits relative to plumbing, electrical, and HVAC businesses — buyers often compare across the trade sector when assessing acquisition targets.
Three Things That Quietly Destroy Roofing Business Value
Revenue concentration. If one builder, strata manager, or insurance assessor represents more than 25% of your turnover, buyers see it as a concentration risk. Losing one client post-settlement could materially change the business they’ve just bought. Diversify before you go to market.
The owner-as-estimator problem. Quoting roofing jobs is a skill — reading plans, scoping materials, allowing for access and height considerations, pricing risk. If you’re the only person who can quote accurately and price the jobs profitably, a buyer is acquiring a business they can’t operate without you from day one. Either train a second estimator or document your pricing methodology in enough detail that it survives your departure.
Ageing equipment and vehicles. Buyers will mentally deduct replacement costs for anything nearing end of life. A scaffold set that needs replacing, a truck with high kilometres, a spray rig that’s been welded four times — all of these come off the implied price. Well-maintained, documented equipment adds confidence. Ageing equipment adds negotiation leverage — for the buyer, not for you.
Getting a Handle on Your Number
The best way to get an accurate picture is a professional assessment — not a business broker’s pitch to list your business, but an independent view of what the business is actually worth based on normalised financials, comparable transactions, and a realistic read on who’s likely to buy it and why.
Tax structure also matters when you sell. The difference between selling shares versus selling assets, and whether you qualify for the small business CGT concessions, can significantly affect what you keep after the transaction. Worth understanding before you receive any offers — see tax on selling a business in Australia for an overview.

FAQ
How can I calculate the value of a business?
For a roofing business, start by normalising your annual profit — add back owner salary above market, personal expenses run through the business, and one-off costs. Apply a multiple of 2x–4.5x depending on your revenue mix, team structure, and whether you have maintenance contracts. That range covers most Australian roofing transactions.
Where do roofers make the most money?
Australian roofing businesses generate their highest revenues in storm-prone regions — South-East Queensland, Western Australia, and the Northern Territory. But the most profitable long-term businesses tend to be commercial maintenance-focused operations, regardless of location. Storm income is high but unpredictable; maintenance income is steadier — and buyers value what’s predictable.
How much is a business worth with $1 million in sales?
Revenue alone doesn’t determine price. A roofing business turning over $1M with 20% net margins generates roughly $200K EBITDA. At a 3x multiple, that’s $600K in goodwill. At 10% margins and a 2.5x multiple, it’s around $250K. Margins and revenue quality matter far more than turnover.
What is the rule of thumb for valuing a business?
For Australian roofing businesses, the rule of thumb is 2x–4x normalised EBITDA. Residential and project-based operations sit at the lower end. Businesses with maintenance contracts, a stable team, and documented systems sit at 3.5x–4.5x or above. Owner-dependent operations without transferable client relationships often sell below the 2x floor.
