How to buy a roofing company (and test whether the revenue lasts)

Published October 25, 2026 · Facts checked as of October 2026

Short answer

To buy a roofing company, first separate revenue by source: retail replacement, insurance-claim (storm) work, commercial roofing and repairs. Storm-driven revenue can spike after a hail or wind season and fall away the next year, so look at three or more years. Then check lead sources and whether they belong to the business or the owner, how crews are engaged (employees or subcontractors), workmanship warranties still outstanding, licensing, and workers' compensation and safety history.

Roofing is a big-ticket, weather-sensitive, labor-heavy business. A roofing company can show one spectacular year that doesn't predict the next.

Worked example: averaging out the storm year

Illustrative example, not a real company

A company's revenue over four years: $2.1 million, $2.3 million, $4.6 million (the year after a major hailstorm) and $2.9 million (the most recent year, with storm work still trailing off). Earnings before the owner were $310,000, $340,000, $920,000 and $480,000. The seller prices on the last two years' average: ($920,000 + $480,000) ÷ 2 = $700,000. The four-year average is ($310,000 + $340,000 + $920,000 + $480,000) ÷ 4 = $512,500. Strip storm work out of each year using the job list (job source tells you which were insurance claims) and the steady business may be closer to the first two years. Which number you believe changes the deal by hundreds of thousands. Lenders use historical earnings and will ask the same question.

Insurance work: receivables, deductibles and state rules

Storm restoration revenue arrives through homeowners' insurance claims, which means slower collections, supplements negotiated with adjusters, and the homeowner's deductible collected separately. Ask for receivables aged by carrier and by homeowner. Some states regulate how contractors interact with insurance claims, including restrictions on contractors acting like public adjusters and on waiving or rebating deductibles. If the company's sales pitch relies on practices your state restricts, that revenue isn't something to pay for. Ask the seller how claims are handled and have your attorney check the state's rules.

Add-back and liability traps

Documents to request

Crews, safety and licensing

Falls are a leading cause of death in construction, and OSHA's fall protection standard for construction (29 CFR 1926, Subpart M) applies to roofing work. Ask for the safety program, the injury log, any OSHA citations, and the workers' compensation experience modifier, which affects premiums and whether commercial customers will hire the company. Many roofers use subcontracted crews. Get every subcontract, certificates of insurance (general liability and workers' comp), and check whether crews are treated like employees in practice. If a sub's worker is hurt and the sub has no coverage, the claim may land on you. Licensing varies: some states license roofers specifically, others through general contractor licences, and cities may add their own. Find out who holds the licence and whether it stays.

Worked example: pricing workmanship warranties you inherit

Illustrative example, not real claim rates

The company installed about 1,800 roofs over the last ten years with a 10-year workmanship warranty. Its claims log shows 2% of roofs needing warranty work, at an average cost of $1,600 per claim, spread over the warranty period. Roughly 1,800 × 2% = 36 claims across ten years, or about 3.6 a year; at $1,600 each, about $5,800 a year. Modest, if the log is complete. Now ask whether claims were recorded consistently: if the seller fixed many leaks himself on weekends without logging them, the real rate could be several times higher. Treat the warranty book as a liability, estimate it from the records, and negotiate a holdback or price adjustment if the records are thin.

What moves the value of a roofing company

We don't value deals or publish multiples we can't verify. Appraisers and lenders weigh these factors:

FactorSupports a higher valuePulls it lower
Revenue sourceRetail replacement and repairs, steady across yearsStorm work from one event
Lead generationOwned channels: referrals, reviews, repeat customersPaid leads and door-knocking that stop when the owner leaves
SalesSeveral trained estimatorsOwner inspects and sells every roof
CrewsStable, insured, properly engagedUninsured subs, classification risk
Warranty exposureLow claims, documented workmanshipRising callbacks
SafetyLow experience modifier, clean OSHA historyCitations, serious injuries

The first 90 days after you buy

Confirm the licence holder, insurance and workers' compensation are in place for your entity before the first job. Keep crews and estimators, and finish every job in progress to the seller's standard; a leaking new roof in month one is the worst possible introduction. Review open insurance claims and receivables weekly, and set up your own warranty tracking so you know what you've promised.

How jobs are sold, and who owns the leads

Roofing revenue depends on how the work is sold: door-to-door canvassing after storms, referrals and repeat customers, insurance adjuster relationships, or general contractors. Ask for revenue by lead source for three years. If commissioned sales reps sell most of the jobs, read their agreements: commission rate, when it is earned, clawbacks on cancelled or unpaid jobs, and any non-solicitation terms. A team of reps who could leave together and take the pipeline with them is a risk you should price.

Ask too whether crews are employees or subcontractors, and how they are insured. Subcontractor crews without their own workers' compensation can leave the company liable for injuries on its jobs.

Questions to ask the seller

Material costs and supplier accounts

Shingles, underlayment and other materials can be a large share of job cost, and prices change. Ask for supplier invoices and job cost reports for a sample of jobs, and check how quickly the company passes price changes through to customers. Find out which supplier accounts and credit terms the business has, and whether those terms rely on the seller's personal guarantee. You may start on less favourable terms until suppliers know you, which affects working capital.

Ask for the company's online reviews over time, too. A sudden change often follows a crew or sales team change.

Frequently asked questions

Why is storm work risky for buyers?

Insurance restoration volume depends on weather events. A record year after a big storm can be followed by a much quieter one. Average across years and look at revenue by job type.

Are roofing crews usually employees?

Many roofing companies use subcontracted crews. That shifts labor cost but raises classification, insurance and quality-control questions. Check contracts and certificates of insurance.

What warranties should I worry about?

Workmanship warranties the company gave on past roofs. If you buy the entity, those obligations come with it; in an asset purchase, customers may still expect them honored.

Is roofing licensed?

Many states and localities license roofing contractors or require general contractor licences. Requirements vary; check where the company operates.

How do I verify a roofing company's revenue?

Tie the job list (customer, address, contract amount, insurance carrier if any) to invoices, bank deposits and tax returns. Material purchases from roofing distributors are a strong cross-check: shingles and underlayment bought should roughly match the squares installed. Insurance jobs should also show carrier payments and homeowner deductibles collected.

Should I buy a roofing company's stock or its assets?

Asset purchases are common because they leave behind claims from past jobs, but customers with workmanship warranties may still expect the business to honor them, and licences may need to be reissued. In a stock purchase every past job's warranty and liability comes with the company. Price the warranty exposure either way, and have your attorney review the warranty terms.
