Seller’s discretionary earnings and EBITDA are two ways to measure the same thing — the real, ongoing profit a roofing business produces — and the main difference between them is how they treat the owner’s salary. SDE adds one owner’s full pay back into earnings; EBITDA leaves a market-rate salary for whoever runs the company inside the earnings. Which one a buyer uses depends on the size and shape of the business.
The short version: SDE is the earnings measure for smaller, owner-operated roofing companies where the owner works in the business every day, and EBITDA is the measure for larger, managed companies that do not lean on a single person. Both are just the earnings figure that a multiple gets applied to — the multiples themselves live in what is a roofing business worth, and the operational reasons a buyer pays more or less live in what drives a roofing business’s value. This post owns the definitions: what each measure means, how they differ, and which one fits your company.
SDE and EBITDA, in one breath
Start with what both measures are trying to do: show the true earning power of a roofing business, stripped of one owner’s particular accounting choices. Raw net profit rarely does that, because how much profit a company reports depends on how the owner pays themselves, what personal expenses run through the books, and one-time costs that will not repeat. SDE and EBITDA are two standardized ways to cut through that noise. They start from the same place — the company’s profit — and they add certain things back to reveal the earnings a buyer can actually count on. The difference is in exactly what each one adds back, and that difference, small as it sounds, is what decides which measure a buyer reaches for.
What seller’s discretionary earnings means
Seller’s discretionary earnings, or SDE, is built around the working owner. It takes the roofing company’s net profit and adds back the full compensation and perks of a single owner — the salary, the benefits, the vehicle, the personal costs run through the business — along with interest, taxes, depreciation, and amortization. The logic is straightforward: for a small, owner-operated roofing business, a buyer is really buying a job plus a profit. Whoever takes over will step into the owner’s role and could pay themselves that salary or keep it as profit — either way, it is money the business generates that is available to a working owner. So SDE folds that owner’s pay back in to show the total financial benefit the business delivers to the person running it. That is why SDE is usually the larger of the two figures for an owner-run company: it counts the owner’s pay as part of the return.
What EBITDA means
EBITDA — earnings before interest, taxes, depreciation, and amortization — is built around a company that runs on hired management rather than one owner’s labor. It also starts from profit and adds back interest, taxes, depreciation, and amortization, but it does not add back a market-rate salary for the people running the business. That salary stays in as a real cost, because in a larger roofing company the management doing the work has to be paid whether or not the owner shows up. EBITDA is meant to show what the business earns after covering the true cost of running it, which makes it the natural measure for a company where the owner is more of an investor than a day-to-day operator. Because it leaves management pay inside the earnings, EBITDA is typically the smaller figure for a business of any given size — it reflects a company that already stands on its own management, not on the owner’s daily effort.
The core difference: the owner’s salary
Everything separating the two measures comes down to one line: the owner’s salary. SDE adds a full owner’s pay back into earnings; EBITDA leaves a market-rate management salary in. That single choice reflects two different questions about the same roofing business. SDE asks, “What would a working owner take home from this business, all in?” EBITDA asks, “What would this business earn for an owner who paid someone else to run it?” In a small company where the owner is the estimator, the salesperson, and the crew boss, the first question is the honest one — a buyer is stepping into that role. In a large company with a general manager and superintendents already on payroll, the second question is the honest one — the earnings should reflect the cost of the management that actually runs the work. The measures are not in conflict; they simply describe businesses at different stages of independence from the owner.
Why smaller, owner-operated roofers are valued on SDE
For a roofing business where the owner is genuinely in the business — pricing jobs, meeting customers, running or supervising the crew — SDE is the honest measure because it matches how a buyer will actually take over. That buyer is almost always another owner-operator who plans to do the same work the seller does, and who therefore expects to earn the owner’s salary and the profit both. SDE captures that combined benefit in a single figure, which is why the market for smaller companies has settled on it. It also keeps comparisons fair: two owner-run roofing businesses might pay their owners very differently, and adding the owner’s compensation back puts them on the same footing so a buyer can compare the underlying earning power rather than one owner’s pay habits. When you read a valuation range expressed as a multiple of SDE, that is the audience it is built for — the working owner buying a working business.
Why larger roofing companies are valued on EBITDA
Once a roofing company grows past a single owner’s reach — a management layer runs the work, superintendents supervise the crews, an office handles estimating and scheduling — EBITDA becomes the honest measure. At that scale the buyer is often an investor or a larger company that will not personally run the jobs; they will rely on the management already in place, and that management has to be paid. Leaving a market-rate salary for those managers inside the earnings shows what the business truly earns after the real cost of running it, which is exactly what such a buyer needs to see. EBITDA also travels better between businesses of different sizes because it does not hinge on one owner’s particular pay, making it the common language for larger transactions. The shift from SDE to EBITDA is really a signal of a business maturing away from owner-dependence — which, not coincidentally, is one of the drivers that lifts value in the first place.
Real-World Scenario: Two roofing companies each report the same modest net profit. In the first, the owner does everything — sells the jobs, prices them, and runs the lead crew — and pays themselves a healthy salary out of the business. In the second, the owner has stepped back; a general manager runs operations, superintendents oversee the crews, and the owner takes only a small salary. A buyer’s advisor would look at the first through SDE, adding the owner’s full pay back to show what a new working owner would take home — a noticeably larger earnings figure. The advisor would look at the second through EBITDA, leaving the management salaries in as real costs, because a buyer inherits those costs. Same reported profit, two different lenses — because the two businesses depend on their owners in completely different ways, and the earnings measure has to reflect that.
What normalizing the books means and why a buyer does it
Neither measure means much until the books are normalized, and understanding that step keeps an owner from being surprised in diligence. Normalizing is the cleanup a buyer’s advisor performs to reveal a roofing company’s true, ongoing earnings: removing one-time costs that will not recur, stripping out personal expenses run through the business, and adjusting owner compensation up or down to a market rate. Only after that cleanup does SDE or EBITDA carry real meaning, because only then is the earnings figure comparable to other companies rather than shaped by one owner’s choices. For an owner, the practical lesson is that clean, well-organized books make normalizing easy and the resulting earnings believable — and that a buyer discounts what cannot be verified. The measure a buyer applies matters, but the quality of the books underneath it matters just as much.
Which lens fits your business — and where it meets coverage
The quick test is how much the roofing business depends on you. If you are still the engine — selling, estimating, running crews — a buyer will most likely read the company through SDE. If you have built a management layer and the work runs without you in every decision, EBITDA becomes the lens, and the very fact that it does usually signals a more valuable, more transferable company. Neither figure is a value by itself; each is the earnings number a multiple gets applied to, and the what is a roofing business worth post walks how those multiples work, while what drives a roofing business’s value walks the operational drivers that move them. The same normalized financials a buyer studies are the ones a carrier reads when pricing the risk, which is why building a clean, well-run, less owner-dependent roofing business pays off on both sides.
