How Much Is a Roofing Business Worth in Australia?
A roofing business in Australia is typically worth between 2 and 4 times its annual owner earnings — what most buyers and brokers call EBITDA, or earnings before interest, taxes, depreciation, and amortisation. For a well-run residential roofing business turning $1.5 million in revenue with $300,000 in owner earnings, that means a sale price somewhere between $600,000 and $1.2 million, depending on a handful of factors that most sellers don't know matter.
The variance in that range isn't random. It reflects real differences in risk, repeatability, and how dependent the business is on the owner to function at all.
This is the same framework covered in Module 4 of the Playbook — if you're buying or considering selling, it's worth understanding how valuers think about this before you sit down with a broker.
What EBITDA Multiple Should You Expect?
Most Australian roofing businesses sell at 2x to 4x normalised EBITDA. The average sits around 2.5x to 3x for a standard owner-operated residential trade business. That multiple jumps toward 4x or higher when the business has strong recurring work, documented systems, and minimal owner involvement in day-to-day operations.
A few reference points from recent market activity:
- Sub-$500K revenue: Often sold asset-only, valued more on equipment and goodwill than EBITDA. Sale prices typically $100K–$300K.
- $500K–$2M revenue: EBITDA multiples of 2x–3x are most common. At $200K EBITDA, expect $400K–$600K.
- $2M–$5M revenue: Buyers pay 3x–4x for businesses with proper systems, commercial contracts, and non-owner-dependent operations.
- $5M+ revenue: Strategic buyers and roll-ups enter the picture. Multiples can reach 4x–5x if there's a genuine management team in place.
Plumbing business valuations work similarly — the same EBITDA framework applies across most trades, with slight differences depending on licensing complexity and how recurring the revenue is.
One rule of thumb worth knowing: a multiple of 3x EBITDA implies the buyer expects to recover their investment in about three years from earnings alone — before debt service, before any growth. That's the floor for what most buyers find acceptable.
What Actually Drives the Multiple Up (or Down)
The multiple isn't a number you find in a spreadsheet. It's a judgement about risk. Here's what moves it.
Owner dependency
This is the single biggest value killer in trade businesses. If the roofing business relies on the owner to quote jobs, manage crews, or maintain key customer relationships — buyers discount heavily, because the business doesn't really exist without that person.
I've seen brokers list roofing businesses at 3x and watch them actually transact at 1.8x once buyers understand the owner quotes every job and the three lead roofers are family members. (The family member issue is a separate problem, but it compounds quickly.)
If you're selling, the most valuable thing you can do before going to market is step back from the tools and the quoting process — even for 12 months — to demonstrate the business can run without you.
Residential vs commercial mix
Commercial roofing work — schools, warehouses, strata complexes, retail centres — generally attracts a higher multiple because it comes with longer contracts, repeat billings, and more predictable forward revenue. Purely residential work is transactional: once the job is done, there's no guarantee the customer calls back.
A business with 30% commercial contract work and 70% residential will often attract a meaningfully better multiple than an identical-revenue business with no commercial relationships at all.
Subbies vs employed crews
A roofing business built entirely on subcontractor labour has a different risk profile than one with employed, trained teams. On one hand, lower fixed cost base. On the other, zero control over quality, availability, or licensing compliance — and buyers know it.
Employed crews add payroll cost, but they also add predictability and defensible quality. Most sophisticated buyers prefer a mix: a small core of employed supervisors and estimators, with flexed subcontractor labour for volume.
Licensing and compliance
Roofing is a licensed trade in most Australian states. Queensland, NSW, and Victoria all have their own licensing frameworks. A business with proper contractor licences held by employed staff (not solely the selling owner) is worth more than one where the licence walks out the door with the previous owner.
This also affects the timeline of any deal — if a licence transfer adds eight weeks to settlement, some buyers will reprice accordingly (or walk).
Seasonality and geographic concentration
Roofing in northern Queensland or the NT is more weather-sensitive than work in Melbourne or Adelaide. Summer cyclone exposure, wet season shutdowns, and heat-related productivity drops all affect consistency of earnings. Buyers in affected regions expect to see at least two full years of financials to understand the seasonality pattern — and they'll normalise for it.
How to Calculate What Your Roofing Business Is Worth
The calculation starts with normalised EBITDA — the actual owner earnings the business produces, adjusted for things that distort the reported profit figure. Common adjustments include:
- Adding back owner salary above what you'd pay a manager to replace yourself
- Adding back personal expenses run through the business (vehicle, phone, sometimes much more)
- Removing one-off costs or revenue items that won't recur
- Adjusting for below-market or above-market rent if the premises are related-party
The result is a clean number: what would this business earn if someone else was running it?
Then apply a multiple. If normalised EBITDA is $280,000 and the business attracts a 3x multiple, the enterprise value is $840,000. From there, you adjust for working capital (whether receivables are above or below normal), equipment condition, and whether the deal is structured as an asset sale vs share sale.
If you want to do this properly before talking to a broker, the EBITDA normalisation checklist walks you through every common add-back line by line.
What Buyers Are Actually Paying in Australia Right Now
The Australian roofing sector has seen steady transaction activity in the $500K–$3M revenue range. Demand from owner-operators and small PE-backed roll-ups has kept multiples relatively stable — this isn't a sector where sellers are taking distressed prices.
That said, the financing environment matters. Most buyers in this range are using a combination of bank debt (typically 50%–60% LVR on business acquisitions) and vendor finance or equity. A roofing business with clean books and three years of consistent earnings is financeable; one with undeclared cash and irregular BAS lodgements is not — regardless of what the owner thinks it's worth.
One broker told me recently about a deal where the seller had been running a profitable roofing business for 15 years, but had declared minimal profit for tax purposes (which is fair enough, as a strategy). When it came to selling, they couldn't demonstrate the earnings — and the buyer couldn't get finance. The business sat on the market for 18 months before eventually selling at a steep discount for asset value only. It's a very common outcome.
Before you sell, getting your financials in order for at least two to three years is non-negotiable. Read more about how to check financials when buying a business — the same checklist applies in reverse when you're preparing to sell.
What the ATO Says About Roofing Benchmarks
The ATO publishes benchmark data for roofing services, which gives you a sense of where a typical business sits. Their figures show cost of sales running between 55% and 70% of turnover for roofing contractors, with labour the dominant cost.
If your margins are materially outside those ranges, a buyer or their accountant will ask why — and you'd better have a good answer. Significantly higher margins might indicate unreported cash; significantly lower might signal operational inefficiency or underpricing. Both are flags.
The ATO benchmark isn't a valuation tool — it's a reasonableness check. Buyers use it when they're trying to understand whether the numbers they're being shown are plausible.
Get a Second Opinion Before You Price It
Most business owners overprice on the way in and undersell on the way out. The seller anchors to the life they've put into the business; the buyer prices what the numbers support.
The gap between expectation and reality is almost always narrowed by good preparation — clean books, documented processes, and a business that demonstrably functions without its owner present for six weeks.

Frequently Asked Questions
How much is a roofing business worth in Australia?
A typical Australian roofing business sells for 2x–4x normalised EBITDA (owner earnings). At $300,000 in annual earnings, expect $600,000–$1.2 million. The multiple depends on owner dependency, revenue mix, systems, and crew structure.
Is a business worth 3 times profit?
Three times annual profit (EBITDA) is a common reference point for small trades businesses in Australia. Well-systematised businesses with recurring revenue attract 3.5x–4x; owner-dependent operations often transact at 2x–2.5x.
How do you calculate the value of a roofing business?
Start with normalised EBITDA — add back owner salary above replacement cost and any personal expenses run through the business. Multiply by a relevant multiple (2x–4x for roofing). Adjust for working capital and deal structure.
Does residential vs commercial work affect the price?
Yes, meaningfully. Commercial roofing contracts improve multiple because they're more predictable. A business with 30%+ commercial revenue will typically attract a better multiple than a purely residential operation of the same size.
What kills the value of a roofing business?
Owner dependency is the biggest value destroyer — if the owner quotes all jobs and manages all client relationships, buyers price in execution risk. Poor records, licensing held solely by the owner, and heavy reliance on cash revenue all reduce value significantly.
