How Much Is a Roofing Business Worth?
A roofing business is worth what its repeatable earnings support after a market wage is paid for the owner’s own work, adjusted for how much of that profit would survive a quiet weather year and the loss of any one builder or insurer. Re-roofing and restoration work from direct customers, a trained crew and a clean safety record support a higher value than storm-driven profit or work from one or two builders.
- Storm and insurer work is real income but is allocated rather than owned, so only the repeatable part is capitalised.
- Builder work won at a fixed price per roof is exposed to one site manager’s decision and to the builder’s solvency.
- Falls from roofs are the central risk, so the safety record and working at heights system are part of the evidence for the earnings.
- Roof plumbing can be regulated plumbing work, so who holds the licence matters.
- A valuer tests what the business earns if its largest source of work disappears while the overheads stay.
What decides the value of a roofing business?
How much of the profit would still be there once the owner has gone and the weather has returned to normal. A roofing business that re-roofs homes and restores roofs for direct customers, one that roofs new builds for two project builders and one whose best year came from a single hailstorm can report the same profit and be worth very different amounts.
The profit in the tax return is only the starting point. A valuer rebuilds it into the earnings a new owner could reasonably expect to keep, then tests which parts of it repeat. The factors are set out on our page on roofing business valuations. Every figure in this guide is illustrative and none is a benchmark.
In many roofing businesses the owner measures, quotes, deals with the assessor and inspects the finished roof. We deduct a market cost for those roles and ask who else could estimate, hold the customer relationships and sign off quality.
How is storm and insurance work treated?
As real income that is allocated rather than owned. Insurer and assessor work can fill a crew for months, and a hailstorm or cyclone can produce a year of profit that does not repeat. We look at which insurer panels or repairer networks the business sits on, how it got there and who holds the assessor relationships, and at several years of results to find what the business earns without a major weather event.
The event year is treated as a spike, and the report is built on what remains once it is set aside or averaged. Restoration, leak repairs and gutter work from direct customers are steadier, which is why we ask whether the business keeps records of past customers and follows them up. Rain and wind stop roof work while crews, vehicles and equipment still cost money, so we also ask how many days were lost in past years and whether quiet periods are managed or simply absorbed.
Is builder work worth less than re-roofing for homeowners?
Per dollar of profit, it is usually read as riskier. New-build roofing is won from a handful of builders at a fixed price per roof, often through one site manager. Volume can be strong when housing starts are high and fall sharply when one builder slows down, changes roofer or fails. Re-roofing is sold to owners, landlords and insurers one roof at a time, with a wider spread of customers but more marketing cost.
Most roofing is quoted from a measure before steel, sheeting or tile prices are confirmed, and hidden repairs such as rotten battens have to be recovered as variations. So we compare quoted and actual margin on completed jobs. Our guide on customer concentration and business value explains why reliance on a few customers lowers value for a given profit.
Payment terms differ as well. Direct customers often pay a deposit and a final balance, builders pay on progress claims or at stage completion, and insurers pay against an approved scope after the job is invoiced. We check debtor ageing, insurer payment times and how extra scope is settled.
What does a worked example look like?
The illustrative business below earns from three streams. We build maintainable EBITDA from the contribution of each, using a typical year for insurer work, and then test what happens if the insurer work ends. Contribution here means revenue less direct labour, materials and job costs.
Illustrative roofing business: earnings by stream and an exposure test
Illustrative- Direct re-roof and restoration: revenue of $1,500,000 at 24%
- $360,000
- Builder new-build roofing: revenue of $1,100,000 at 14%
- $154,000
- Insurer repairs in a typical year: revenue of $600,000 at 20%
- $120,000
- Total contribution
- $634,000
- Less: overheads, including office, insurance, yard and vehicles
- $290,000
- Less: owner’s estimating, insurer liaison and roof inspection at market cost above wages paid
- $70,000
- Maintainable EBITDA
- $274,000
- Enterprise value at 3.0 times, a multiple chosen for illustration
- $822,000
- Test: maintainable EBITDA if the insurer work ended and overheads stayed
- $154,000
- Test: value at the same illustrative multiple
- $462,000
Illustrative figures only. The margins and the multiple are chosen to show the method and are not market figures. The result is an enterprise value, before debt and surplus assets.
Insurer work is about 19% of revenue ($600,000 of $3,200,000) but 44% of maintainable EBITDA ($120,000 of $274,000), because the overheads stay when the work goes. We do not delete a stream like that. We reflect the exposure in the risk applied and in how the earnings are described. In a real report the multiple would also be argued from evidence, as our guide to how trade businesses are valued explains.
How do safety, licences and warranties affect the value?
Falls from roofs are the central risk in the trade, and work health and safety laws put duties on the business as well as the roofer. We read the safety management system, training and induction records, incident history and workers’ compensation premium trend. A poor record is a cost a buyer inherits, and a good one is evidence the business is run properly. We also check whether edge protection and scaffolding are priced into every quote, because margin lifted by cutting back on protection is margin a buyer will have to give back.
Fitting gutters, downpipes and flashings can be regulated plumbing work in several states, so we ask who holds which licence and what each person is licensed to do. Roofers also give workmanship warranties, often beside manufacturer warranties that depend on correct installation, and leaks can appear years later. We read the claims history. What a buyer would need to hold is a question for the licensing authority or your lawyer.
What reduces the value of a roofing business, and what increases it?
What tends to reduce value
- Profit from one storm season or one insurer allocation. It may not return, and the allocation can move.
- One or two builders supplying the new-build work. The loss of one removes revenue while the crews and overheads remain.
- Safety gaps. Missing edge protection, thin training records or a poor incident history are costs a buyer has to put right.
- An owner who measures, quotes, deals with assessors and signs off every roof.
What tends to increase value
- Direct re-roofing, restoration and repair work, with a customer list that is followed up.
- A documented safety system and a stable crew that has worked together for years.
- More than one person who can estimate and hold customer relationships.
- Quoted margins that match actual margins on completed jobs.
What should you prepare before a roofing business valuation?
Records that separate the streams and show how repeatable each is. The most useful items are:
- Revenue and job counts for three years split into re-roofing, new construction, insurer and storm work, restoration and repair, and commercial.
- Revenue by insurer and builder, with panel or supply agreements and approved scopes of work.
- Licence holders and classes, including roof plumbing and any licence for removing older fibre cement roofing where the business does that work.
- The safety management system, training records, incident register and workers’ compensation premium notices.
- Employee and subcontractor lists with pay basis and insurance certificates.
- Warranty terms offered and a warranty claims register.
If you are a tradie weighing up a sale, a partner buying in or a succession plan, an independent valuation sets out the earnings and the reasoning in writing. Our pages on business sale and succession valuations explain what the report needs to address. An Independent Business Valuation is $1,995 + GST, and you can start online.
