How to Value and Sell a Commercial Roofing Company

Selling a commercial roofing business is not like listing a house. Buyers are sophisticated, due diligence runs deep, and the difference between a good deal and a great one often comes down to how well the owner prepared before they ever picked up the phone.

Whether you're thinking about an exit in 12 months or five years, understanding how your company gets valued is the first thing you need to get right.

The most common valuation method for commercial roofing businesses is a multiple of EBITDA (earnings before interest, taxes, depreciation, and amortization). 

For most small to mid-size commercial roofing companies, that multiple lands between 3x and 6x.

Companies with $5M+ in revenue, recurring maintenance contracts, and a management team that doesn't need the owner in the building every day tend to land toward the higher end.

Revenue alone doesn't move the needle much. A $10M company with thin margins and one customer representing 40% of revenue might fetch a lower multiple than a $6M company with diverse accounts and a 12% net margin.

Buyers price risk. Concentration, whether in customers, employees, or geography, is risk.

A few specific factors that influence where your multiple lands:

• Gross margin percentage (commercial roofing averages run roughly 20-30% gross margin)
• Percentage of revenue from recurring maintenance or service contracts vs. one-off projects
• Customer concentration (no single customer should represent more than 15-20% of revenue if you want top dollar)
• Owner involvement in day-to-day operations
• Backlog size and quality at the time of sale
• Age and condition of equipment
• Reputation, licensing, and any outstanding litigation

Expect any serious buyer to request three years of tax returns, three years of profit and loss statements, an aging accounts receivable report, and a current balance sheet. They'll also want a breakdown of revenue by customer and project type.

One thing many sellers don't anticipate: buyers will recast your financials.

 Recasting (also called normalization) means adjusting reported earnings to remove personal expenses run through the business, one-time costs, and above-market owner compensation. 

This gives a cleaner picture of true earnings. If you've been running personal vehicle expenses, a boat, or a family member's salary through the company, a buyer will add those back to arrive at seller's discretionary earnings (SDE) or adjusted EBITDA.

These ranges are general. A particularly well-run company can exceed them. A business with obvious problems will come in below.

The buyer landscape has changed significantly since private equity started rolling up specialty contractors around 2015. Today, you'll generally encounter three types of buyers.

Strategic buyers are larger roofing contractors, national service companies, or facility maintenance platforms looking to expand into a new geography or add capacity.

They often pay the highest prices because they can realize synergies (shared crews, equipment, overhead) that an individual buyer can't.

PE-backed platforms are private equity-sponsored roofing companies that are actively acquiring smaller operators to build scale.

They move fast, know the numbers, and typically require the seller to stay on for 12-36 months post-close. If you're not willing to stay involved after the sale, make that clear upfront.

Individual buyers are usually owner-operators or entrepreneurs buying their first business. They often rely on SBA financing, which means more time, more paperwork, and deal structures that may require seller financing.

The upside: they don't push as hard on earnouts and may be a simpler close for smaller companies.

Most business brokers will tell you the ideal time to start preparing is two to three years before you want to exit. That's not just a sales pitch. It takes time to fix the things that drag down your multiple.

Here's what actually moves the needle:

• Reduce owner dependency. Document your estimating process. Promote a project manager who can run jobs without you. Buyers will not pay a premium for a business that stops functioning when the owner leaves.
• Grow your service/maintenance contract book. Recurring revenue is valued higher than project-based revenue because it's predictable. Even adding 10-15% of total revenue as recurring contracts can improve your multiple.
• Diversify your customer base. If one client represents 30% of your revenue, spend the next two years winning new accounts.
• Clean up your books. Get a CPA to prepare reviewed or audited financials. This builds buyer confidence and speeds up due diligence.
• Address deferred maintenance. A buyer's inspector will find everything. Fix it before it becomes a price reduction conversation.

Once you're ready to go to market, the process typically follows this sequence:

1. Hire an M&A advisor or business broker with specific experience in construction or specialty contracting. General business brokers often undervalue these companies.
2. Prepare a confidential information memorandum (CIM): a detailed document covering financials, operations, customer profile, and growth opportunities.
3. Identify and approach potential buyers under NDA.
4. Receive and compare letters of intent (LOIs). The highest offer isn't always the best. Look at deal structure, earnout provisions, and seller note requirements.
5. Enter exclusivity with the winning buyer and complete due diligence (typically 60-90 days).
6. Negotiate and sign a purchase agreement.
7. Close and transition.

The entire process from engaging an advisor to closing typically takes 6-12 months. It can move faster with a clean business and a motivated buyer. It can drag longer if due diligence surfaces surprises.

Not all purchase prices are created equal. A $4M offer with 100% cash at close is worth more than a $5M offer where $1.5M is tied to hitting post-close revenue targets you may not control anymore.

Earnouts are common in this industry and often reasonable, but the terms matter more than the headline number.

Seller notes (where you finance part of the deal yourself) are also frequent, especially with individual buyers or SBA transactions. A seller note typically ranges from 5-15% of the deal value and carries an interest rate of 6-8%.

When reviewing an LOI, pay attention to: what percentage is paid at close, earnout structure and measurement period, any personal guarantees required, employment or consulting agreements post-close, and non-compete terms (geography and duration).

The structure of your sale determines how much you actually keep. An asset sale (most common for smaller companies) typically means the buyer buys the company's assets rather than its stock. 

The tax treatment differs by asset class: goodwill is taxed at capital gains rates, while equipment and other assets depreciated below market value trigger ordinary income tax on the recaptured depreciation.

Talk to a CPA or tax attorney before you sign anything. Restructuring the deal or timing the close differently can sometimes save six figures in taxes. This is not something to sort out at the closing table.

Selling a commercial roofing company rewards preparation more than almost any other factor.

The owners who get the best outcomes are the ones who treated the exit as a multi-year project, not a transaction they figured out when they were ready to leave.
