How to Value a Roofing Company in Illinois

Roofing companies in Illinois are valued at 2.5x to 4.5x SDE, with commercial roofing businesses consistently commanding the higher end. Residential-only storm-damage-focused roofers, while often highly profitable in good years, face volatile revenue tied to hail seasons and insurance claim cycles, which reduces buyer confidence and multiples.

Commercial vs. Residential Mix

Commercial roofing businesses with facility management contracts, preventive maintenance agreements, and service call revenue have more stable, predictable cash flow than residential replacement-focused companies. Illinois commercial roofing serves a large base of industrial, retail, and institutional flat-roof buildings requiring regular maintenance and planned replacements.

Crew and Subcontractor Model

Buyers evaluate whether crews are employees or subcontractors. Employee-based crews provide more quality control and schedule reliability; subcontractor models reduce payroll risk but create misclassification liability if not properly structured. Illinois labor laws around subcontractor classification are strict and will be evaluated during due diligence.

Roofing businesses with insurance restoration experience, established adjuster relationships, and Xactimate estimating capabilities are more valuable to buyers who want to pursue storm-damage work alongside their core service business.

How Illinois buyers put a number on how to value a roofing company

This page is the valuation guide. It is not the sale-process playbook. Seller’s discretionary earnings (SDE) is the cash a full-time working owner can take after you normalize the books. Start with the tax return. Add owner pay and one-time costs. Subtract the wage you must pay to replace the owner.

Roofing recasts have to survive a year without a hail event. Add back owner compensation, then isolate storm-restoration revenue, manufacturer-warranty callbacks, and any unlicensed crew-boss coded as production. A 2.5x–4x SDE band is planning language for a crew that can sell and install without the next supercell; storm-only books get a haircut.

Planning band on this vertical: 2.5x–4x SDE. That is a range, not a quote. BizBuySell’s Q2 2026 Insight Report showed a 2.7× cash-flow multiple across all reported closed deals. Do not use that marketplace average as this shop’s appraisal.

A worked planning example (illustration)

Illustration only — not a quote for any Illinois shop. A roofing companie whose tax return shows $165,000 of net profit is not worth $165,000 × a rumor multiple.

Add back the owner’s $130,000 W-2 and payroll tax, $28,000 of discretionary benefits, $10,500 of accepted one-time cost, and $12,000 of personal expenses that a buyer will not run. Then subtract $30,000 of replacement labor if the owner still diagnoses, sells, or closes the books.

Adjusted SDE in this illustration is $315,000. At 3.25x, enterprise value is $1,023,750 before debt, working capital, holdback, and tax.

SDE line items buyers actually use

1. Reported net profit (tax return, not the marketing P&L)
2. + Interest expense
3. + Income taxes (not payroll, sales, or property tax)
4. + Depreciation and amortization
5. + Owner W-2, bonuses, and payroll taxes on the owner
6. + Discretionary owner benefits that a buyer will not keep (auto, personal travel, family on payroll with no role)
7. + Accepted one-time or non-recurring expenses
8. − Market-rate replacement labor for owner work that will not transfer
9. = Seller’s Discretionary Earnings (SDE)

What moves the multiple up or down

• Retail and commercial work that exists in a non-storm year
• Staying qualifying party on the IDFPR license
• Experience-mod and safety record a carrier will renew
• Manufacturer certifications the buyer can keep
• Crew continuity versus a seller who still runs every tear-off

What does not transfer with the price

The Illinois Roofing Industry Licensing Act (IDFPR) requires a roofing contractor license statewide. It is not a municipal courtesy card. Unlimited and limited classifications matter. The license does not automatically follow the assets; the buyer needs their own IDFPR roofing license or a qualifying party who stays.

Diligence that changes the number

• IDFPR roofing license class, qualifying party, and any disciplinary file
• Storm vs retail vs commercial-reroof mix over at least two seasons
• Insurance-carrier and public-adjuster dependency
• Workers-comp experience mod, height-work training, and OSHA log
• Dump trucks, tear-off equipment, and warehouse lease
• Manufacturer certifications (GAF, Owens Corning, CertainTeed) and warranty reserves

Documents to gather this week

1. Three years of signed business tax returns and matching P&Ls
2. Year-to-date P&L, balance sheet, and three months of bank statements
3. Current lease, amendments, and a plain-English remaining term
4. License and permit list, including who holds each card
5. Top-customer concentration (names redacted until an NDA)

A simple Illinois close calendar

Plan six to twelve months from cleanup to close on a prepared Main Street deal. Start CBS-1 and any Chicago or Cook notices at letter-of-intent, not the week of funding. Landlord consent often takes longer than the lender.
