Where your roof dollar actually goes
Most of your roof bill is not your roof. On a typical residential re-roof, materials and installation labour come to roughly 62 cents of every dollar you pay. A further 14 to 22 cents goes to finding you and closing you — sales commission and marketing. Here is the whole structure, with the parts nobody can honestly source left blank rather than filled in.
$35 Materials — shingles, underlayment, flashing, fasteners, vents
$27 Installation labour, including payroll burden
$8 Sales commission
$9 Marketing and customer acquisition
$79 direct and selling cost → $21 gross contribution
Less $15 overhead — office, vehicles, insurance, software, admin
Leaves $6 net profit.
This is a model, not an audit. No single dataset publishes an authoritative line-by-line national average, and sources classify these components differently — some count commission as a direct cost, others as overhead. The model is consistent with published margin data, but treat it as a reasonable shape rather than a precise measurement.
The line items, and how much we trust each one
The last column is the part most breakdowns leave out. Not every line in a roofing bill is equally knowable, and pretending otherwise is how these articles go wrong.
| Line item | Share of price | What it covers | How well sourced |
|---|---|---|---|
| Materials | 30–40% | Shingles or tile, underlayment, flashing, fasteners, vents, accessories | Good Multiple sources converge near 35% |
| Installation labour | 18–35% | Crew wages plus payroll burden — workers’ comp, taxes, benefits, which add 35–55% on top of base wage | Good Wide but consistent range |
| Sales commission | 6–10% | Typically 8–10% of contract value on company-provided leads, or 25–50% of gross profit on a split | Good Most consistent figure found |
| Marketing & acquisition | 6–12% | Ads, lead purchases, canvassing, brand. Around 7–8% at small operators, 10–12% at large regional companies | Fair Coaching-firm benchmarks |
| Overhead | 12–18% | Office and admin payroll, vehicles, liability and auto insurance, software, accounting, licensing, supervision | Fair CFO advisory benchmarks |
| Tear-off & disposal | 5–10% | Labour to strip the old roof, dumpster, landfill tipping fees | Weak Often bundled into labour or materials — risk of double-counting |
| Permit | 0.5–2% | Usually $150–$500 depending on jurisdiction. The most transparent line on the bill | Good Published fee schedules |
| Warranty reserve | Not published | Money set aside against future workmanship claims. Real, but almost never broken out | None We are not going to invent a number for this |
| Net profit | 5–12% | What the business actually keeps. See the margin section below | Fair See caveats |
Do not add these up. The ranges overlap and the classifications conflict — some sources treat commission as cost of goods, others as overhead; some fold marketing into overhead, others separate it. Summing the midpoints produces a number that looks authoritative and means nothing.
What it costs to get you as a customer
This is the part of your bill that has nothing to do with your roof, and it is larger than most homeowners would guess.
A lead is not a customer. At a realistic 25 to 50% close rate, a $228 lead implies $456 to $912 in media spend alone for one signed job — before you add the estimator’s time, the truck roll, the software and the follow-up calls. Shared marketplace leads run cheaper, $15 to $100 or more, but the same enquiry is sold to several contractors at once, so the close rate falls and the chasing cost rises.
The practical consequence: the contractor who found you through a referral, a neighbour’s yard sign, or their own repeat business did not pay $228 for you. That is real room in their price, and it is the single best reason to ask friends who they used before you start clicking ads.
Get your own roof measured and priced first. It costs nothing and it changes every conversation that follows.
Big company or local contractor?
Commissioned estimators and canvassing crews, inside sales and call-centre staff, project managers, branch premises, brand advertising, warranty administration. Marketing alone runs 10–12% of revenue against 7–8% at a small operator.
They often buy materials cheaper by volume. It rarely offsets the rest.
A lean local contractor can often underbid a heavily marketed regional company by that margin on a comparable retail re-roof — and the gap is explained almost entirely by sales, marketing and administrative overhead, not by materials or the quality of the crew on your roof.
Two honest cautions in both directions. A cheaper bid is not automatically cutting corners — it may simply carry less overhead. And a cheaper bid is not automatically safe either: verify the licence, the insurance and the warranty regardless of company size. We found one widely shared illustration of a $15,000 job costing $20,000 at a large operator, but it comes from a single privately produced source, so treat the mechanism as sound and the specific dollar figure as decoration.
Are roofers getting rich off you?
Mostly, no — and this is where the honest version of this article parts company with the sales-pitch version.
Gross margin at a managed residential replacement company typically runs 25 to 40%. For comparison, a 2024 survey of 1,290 construction companies put best-in-class gross profit at 21.8% across all construction trades.
Net profit margin lands at 6 to 12% for a well-run roofing business. That same 2024 construction survey found 6.3% average net income before tax, and 11.9% for best-in-class. Practitioners treat under 5% as distressed, 5 to 10% as ordinary, and above 12% as strong.
So on a $15,000 roof, a well-run company keeps something like $900 to $1,800 — and spent $1,000 to $1,800 acquiring you to get it. The money in your bill is not mostly going into someone’s pocket. It is going into the cost of reaching you. That is a structural problem with how the trade sells, not evidence that your roofer is greedy.
You may see a claim that the average roofing net margin is 2.8%. It traces back to a misattributed figure and no accessible industry survey supports it for recent years, so we are not repeating it. The most recent association-backed roofing-specific figure we could find is a 6% average, and it dates to 2018.
What Florida adds to a contractor’s costs
Some of the Florida price premium is not margin. It is genuinely more expensive to operate a roofing company here.
Per $100 of payroll for Florida roofing classification 5551 in 2026 — among the highest-rated classes in the state, though down from $8.24 in 2024. On $160,000 of field payroll that is roughly $10,800 before experience modification.
A 2026 broker estimate for a small Florida roofer — $500,000 revenue, three employees, two trucks — across general liability, workers’ comp, commercial auto, inland marine and umbrella. Illustrative, and underwriting varies a lot.
Florida carries roughly a 12% labour premium over the national average, with persistent skilled-labour shortages and an ageing workforce keeping upward pressure on per-square pricing.
Insurance claim work is different — but not in the way people say
The construction scope on a claim roof is identical to a retail roof. What changes is paperwork: documentation, photographs, measurements, adjuster meetings, supplements, code-coverage analysis, payment timing. That is real contractor labour, and it is a genuine cost.
But no published dataset quantifies that administrative premium as a percentage of contract value. The familiar “10% overhead and 10% profit” you will see added to claim estimates is a convention from estimating software and some case law — not a Florida regulatory requirement and not an empirically derived average. If someone presents it as a rule you must accept, they are overstating it.
Worth knowing: assignment of post-loss benefits is void and unenforceable in Florida for policies issued on or after 1 January 2023, under F.S. 627.7152. The old model where a contractor took over your claim rights and negotiated with the carrier directly is gone. You keep control of the claim — which also means the administrative work now happens on your behalf rather than in place of you.
How to use all this
Squares, material line, tear-off layers, a decking allowance per sheet, underlayment by name. You are not trying to audit their overhead — you are checking that the scope is real and comparable between bids.
Two bidders measuring your roof differently produces two totals that cannot be compared. Per-square pricing strips that out and is the only apples-to-apples number.
Not for sentimental reasons. A contractor who did not pay to acquire you has 9 to 14% of job revenue in room that an ad-driven competitor does not.
It may be a lean operator with no showroom. It may also be someone who has left the deck re-nail and the peel-and-stick off the sheet, which in Florida is not optional. The itemisation tells you which.
The commission and the marketing spend are already committed before you meet anyone. What you can do is choose a channel where they were never incurred.
