What does a one-crew Kentucky roofing company need to open?
The canonical configuration is intentionally narrow so the economics can be reproduced in another state without quietly changing the business. It is an independent Kentucky LLC, not a franchise; one mobile installation crew of three wage-and-salary roofers; an owner who estimates, sells, schedules and manages projects; one used three-quarter-ton pickup; one 7×14-class dump trailer; a home-office administrative base rather than a leased showroom; and a core mix limited to residential asphalt-shingle replacements plus repairs. Commercial roofing, metal roofing, gutters and siding are excluded from the Base case.
Startup scope
Why $125,250 is the practical Typical funding target
This is a cash-to-opening model, not a list of accounting expenses. A truck, trailer and tools are capital uses; refundable deposits are cash uses but not expenses; opening supplies are shown once and excluded from initial net working capital; and the operating-cash reserve is distinct from both contingency and working capital.
| Use of funds | Lean | Typical | Premium |
|---|---|---|---|
| Used work truck | $22,000 | $36,000 | $52,000 |
| 7×14-class dump trailer | $7,000 | $12,000 | $15,000 |
| Tools, safety gear & technology | $9,000 | $16,500 | $26,000 |
| Registration & professional setup | $1,200 | $3,750 | $7,000 |
| Insurance binders & deposits | $3,000 | $5,000 | $8,000 |
| Launch marketing + pre-opening payroll | $5,000 | $10,500 | $20,000 |
| Opening supplies + refundable deposits | $2,500 | $4,500 | $8,000 |
| Initial net working capital | $3,000 | $4,000 | $6,000 |
| Opening operating-cash reserve | $18,000 | $25,000 | $35,000 |
| Contingency | $5,000 | $8,000 | $12,000 |
| Total project cost / founder cash, no financing assumed | $75,700 | $125,250 | $189,000 |
Typical combined opening-supplies/deposits row = $3,000 consumables plus $1,500 refundable deposits. Initial net working capital excludes those supplies and is defined as accounts receivable + inventory + prepaid operating items – accounts payable – accrued operating liabilities – customer deposits/deferred receipts; $4,000 is the modeled opening balance. No debt, equipment financing, grant or landlord reimbursement is assumed, so founder cash required = $125,250 project cost – $0 committed external funding = $125,250, and permanent founder equity equals peak interim founder cash.
The trailer line is unusually well anchored. Three current Kentucky observations for new 7×14, 14K-class dump trailers were $11,800, $11,995 and $12,500; the median is $11,995, rounded to $12,000 in the Typical case. A statewide 2021 Ford F-250 listing analysis showed a much higher all-trim median, so the $36,000 truck allowance deliberately targets an older or work-trim unit rather than treating a mixed-trim statewide median as the right founder purchase. Both vehicle and insurance numbers still require quotes before signing.
Launch sequence
A 4 – 8 week launch depends more on local registration than state trade licensing
Kentucky's state-level business formation is relatively light for this model. The Kentucky Department of Housing, Buildings and Construction lists licensing programs for trades such as plumbing, electrical, boiler and fire-protection work, but not a general roofing-contractor trade license. That does not authorize a roofer to work everywhere: the Department of Revenue explicitly tells construction firms to check the city or county of the principal office and each jurisdiction where they transact business.
The 4 – 8 week total is not the sum of those boxes. Formation, insurance shopping, equipment procurement, supplier onboarding and marketing overlap. The critical path is usually whichever local registration/occupancy step must be complete before a contractor account or permit can be issued, plus insurance documentation and crew readiness. Where an authority does not publish a processing SLA, this article does not convert a filing deadline into a fake approval time.
Regulatory gates
Which Kentucky rules can stop a roofing job from starting?
| Requirement | Level / status | Fee / renewal | Dependency | Evidence |
|---|---|---|---|---|
| Articles of Organization | State; mandatory for modeled LLC | $40 initial | Precedes tax accounts and many local applications | KY Secretary of State |
| Annual report | State; recurring | $15; due annually by June 30 | Maintain entity good standing | Official annual-report page |
| EIN | Federal; needed for modeled employer | $0 direct from IRS | Payroll, bank and credit setup | IRS |
| Kentucky tax accounts / MyTaxes | State; employer/entity dependent | No registration fee modeled | Online route preferred; paper can take up to 3 weeks | KY Department of Revenue |
| Limited Liability Entity Tax | State; modeled LLC | Minimum $175 where receipts or gross profits are ≤$3m | Annual business-level tax; not owner income tax | KY Department of Revenue |
| Workers' compensation | State; mandatory with modeled employees | Quote required | Carrier binder often required by local contractor registration | KY Education & Labor Cabinet |
| Local occupational / contractor registration | City / county; varies | Varies by city/county | May require occupancy proof, insurance and tax account | State local-registration warning |
| Roof/building permit per project | Local; scope dependent | Varies by jurisdiction and job | Confirm before mobilization; inspection rules vary | Local quote / authority required |
| Fall protection; EPA lead-safe rules | Federal; OSHA mandatory, EPA conditional | Training/equipment modeled; EPA certification if applicable | Residential fall protection at ≥6 ft; lead-safe rules may apply when disturbing painted pre-1978 components | OSHA + EPA |
For sales tax, Kentucky's contractor guidance matters to the model. The Department of Revenue contractor clarification says contractors are consumers of tangible personal property incorporated into real property, so those purchases are subject to sales tax; the finished construction project is realty rather than a retail sale subject to sales and use tax. Kentucky's sales and use tax page states the statewide rate is 6%. Accordingly, the Base model treats sales tax on job materials as part of materials cost and does not inflate roofing contract revenue with a 6% customer tax pass-through. The revenue-stream map treats both replacement and repair contracts as real-property contractor work under that basis; separately sold products, bundled non-realty services or other fact-specific transactions must be reviewed separately with a Kentucky tax professional.
Local variation and address checks
Large-market example
Louisville's contractor-license materials distinguish annual Type A and one-permit Type B paths and require insurance/employment compliance. Treat those amounts as local examples only, not Kentucky fees.
Local variation and address checks
Urban-county example
Lexington's contractor-registration page requires an occupational business license, insurance and contractor registration; a home-office certificate is $10 and an existing commercial certificate of occupancy is $25 when applicable.
Local variation and address checks
Regional example
Bowling Green/Warren County lists $100 specialty and $250 general contractor licenses, plus insurance requirements and separate occupational-license checks. Scope determines which category applies.
Revenue and capacity
Can one crew support $70,400 a month?
Yes, under this defined mix. The Base case assumes four mid-size architectural-asphalt replacements at $15,400 each plus eight repair jobs at $1,100 each. That is 12 completed jobs per month, not 12 full replacements. The replacement ticket is evidence-led; the repair ticket is deliberately labeled a model assumption because a comparable three-market repair series was not found. At $4,500 of Base monthly marketing spend, the simple blended marketing cost per completed job is $375; true CAC should be tracked by source and won job because referrals and repeat repair work are not separately estimated.
Base monthly revenue = (4 replacements × $15,400) + (8 repairs × $1,100) = $70,400.
Base annualized stabilized revenue = $70,400 × 12 = $844,800.
The $15,400 replacement ticket comes from a current Kentucky state planning basket for a comparable mid-size home and architectural asphalt specification. Three verified 2026 observations (observation 1, observation 2, observation 3) were $12,200 – $19,635, $11,808 – $19,004 and $11,774 – $18,949. Taking each range midpoint and then the median gives about $15,406, rounded to $15,400. This is an observed-price planning basket, not a government average, and roof pitch, tear-off layers, decking, access, insurance scope and shingle system can move a quote substantially.
| Driver / result | Downside | Base | Upside |
|---|---|---|---|
| Replacement jobs | 2.8 | 4.0 | 4.8 |
| Repair jobs | 6 | 8 | 10 |
| Net operating revenue | $49,720 | $70,400 | $84,920 |
| Variable operating cost | $29,040 | $41,209 | $49,645 |
| Fixed non-owner cash cost | $9,000 | $10,000 | $11,500 |
| Fixed owner-replacement labor | $7,606 | $7,606 | $7,606 |
| Passive-owner cash operating profit | $4,074 | $11,584 | $16,169 |
| Working-owner pre-tax business cash benefit | $11,680 | $19,191 | $23,775 |
Downside/Base/Upside hold the same one-crew Typical physical configuration. The fixed-cost tier rises from $9,000 to $11,500 as marketing and administration step up; scenario totals are not plugs. Payment-processing fees are shown as variable costs, not netted from revenue. Calculations use unrounded labor inputs, so displayed rounded components can differ from a displayed result by $1.
Capacity check
A replacement uses about 54 productive crew-hours; a repair uses about seven. Base production therefore consumes roughly 272 crew-hours a month. Upside consumes about 329 hours. Against a planning ceiling near 350 productive hours after travel, loading, weather and non-billable time, Upside is tight but still feasible. A second crew is not hidden inside the Upside case. The monthly scenarios represent stabilized average economics, not a promise of even production: winter weather, heavy rain and storm-driven peaks can shift jobs between months and increase bench payroll or collection timing.
Ramp and collections
The cash model ramps earned revenue at 35%, 55%, 75%, 90% and 100% over months one through five. It assumes 80% of revenue is collected in the earning month and 20% one month later. Customer deposits are treated as deferred cash until work is earned, not as extra revenue or founder funding.
Cost structure
Roofing margins hinge on materials, labor load and leads
The model starts with Kentucky's 2025 roofer median wage of $22.57 per hour from CareerOneStop's BLS-based wage data. Productive crew time is loaded by 37% for payroll taxes, workers' compensation and normal payroll burden. That 37% is a modeled planning load, not an official Kentucky insurance rate; roofing workers' compensation must be quoted.
| Cost line | $/month | % revenue |
|---|---|---|
| Materials / shingle systems | $26,240 | 37.3% |
| Disposal + jobsite fuel/consumables | $4,800 | 6.8% |
| Productive crew labor, fully loaded | $8,409 | 11.9% |
| Processing + callback reserve | $1,760 | 2.5% |
| Variable-cost subtotal | $41,209 | 58.5% |
| Marketing / lead generation | $4,500 | 6.4% |
| GL / commercial auto / tools insurance | $1,250 | 1.8% |
| Weather/bench payroll + training | $1,250 | 1.8% |
| Software, maintenance, office, professional, compliance & admin | $3,000 | 4.3% |
| Fixed non-owner cash-cost subtotal | $10,000 | 14.2% |
The $3,000 combined fixed line comprises $500 software/phones, $700 vehicle/trailer maintenance, $300 home-office/storage, $450 bookkeeping/professional, $150 recurring compliance accrual and $900 other administration. Workers' compensation tied to productive roofing labor is in the loaded labor line, not duplicated in fixed insurance.
Material sensitivity
+$2,480/mo
A 10% increase in the $6,200 material allowance per replacement adds about $620 per replacement, or $2,480 at four Base replacements.
Volume sensitivity
≈$6,065/job
One lost replacement job removes roughly $6,065 of passive/economic contribution before fixed costs, almost halving Base passive profit.
Lead-spend sensitivity
$1-for-$1
An extra $1,500 of monthly lead spend with no additional won work lowers passive cash operating profit by the same $1,500.
Those are the three lines most likely to break the Base case: shingle-system cost, signed replacement volume and lead efficiency. An early-warning dashboard should therefore track contribution per replacement, won-job CAC, direct crew-hours per job, material variance versus estimate, callback dollars, days from completion to final collection and weather backlog. Revenue alone can look healthy while margin leaks through supplements, rework and unpriced decking.
Owner economics
What does the owner really earn?
The Base owner is working in the business, so a clean model must separate compensation for that labor from return on invested capital. CareerOneStop reports a 2025 Kentucky median of $79,370 for general and operations managers. Applying a modeled 15% employer burden produces a fully loaded replacement-labor cost of $91,276 annually, or $7,606 per month.
Passive-owner view
Base contribution of $29,191 minus $10,000 fixed non-owner cash costs minus $7,606 fixed owner-replacement labor leaves $11,584 per month, or about $139,000 annualized, of normalized cash operating profit before D&A. This is the residual business return after paying market replacement labor for the owner's management role.
Working-owner view
Add back only the owner-replacement labor actually avoided by the working owner: $11,584 + $7,606 = $19,191 per month, or about $230,000 annualized. That amount is not “salary.” It combines imputed compensation for the owner's work with the residual return on capital.
Unit economics and break-even
How many jobs cover Kentucky break-even?
The unit model treats productive crew labor as variable because it is driven by job-hours within the one-crew capacity band. The owner's estimating/sales/project-management role is fixed, so its replacement labor belongs below contribution rather than being pushed into every roof.
| Metric | Base result | Formula / basis |
|---|---|---|
| Replacement contribution | $6,065 | $15,400 revenue – $9,335 materials, disposal, loaded crew labor, fuel, processing and callback reserve |
| Repair contribution | $616 | $1,100 revenue – about $484 direct variable cost |
| Weighted Base contribution margin | 41.46% | $29,191 contribution ÷ $70,400 net revenue |
| Weighted average job contribution | $2,433 | Base mix: four replacements + eight repairs = 12 jobs |
| Cash-survival break-even | $24,117 / 4.1 jobs | $10,000 fixed non-owner cash costs ÷ 41.46% contribution margin |
| Sustainable working-owner / passive break-even | $42,462 / 7.2 jobs | ($10,000 fixed + $7,606 target owner replacement labor) ÷ 41.46%; same here because owner role is fixed management |
| Base revenue utilization | 80.0% | $70,400 ÷ $88,000 planning revenue capacity at five replacements + ten repairs |
| Base working-owner project payback | Month 10 | Monthly cumulative pre-tax unlevered cash schedule; Typical $125,250 project cost; 5-month ramp; no distributions during ramp |
| Base passive-owner project payback | Month 17 | Uses manager replacement labor and a larger ~$38,000 ramp reserve, increasing passive startup capital to about $138,250 |
The working-owner payback schedule starts with the full $125,250 capital contribution at month zero, holds the $25,000 opening reserve inside the business, keeps a $20,000 minimum cash floor and makes no distributions during the five-month ramp. A ramp loss funded from that already-contributed reserve is not treated as a second owner contribution. Under the same Typical scope, modeled working-owner payback is month 15 in Downside, month 10 in Base and month 9 in Upside. These are pre-tax, unlevered project results and include an $800/month stabilized maintenance-capex reserve in Base.
State market context
Kentucky demand is broad, but address-level economics still matter
A reliable Kentucky roofing-market revenue amount is not publicly determinable from the category data reviewed here without combining incompatible sources or inventing a statewide spend rate. The better planning approach is to use direct demand and supply proxies, then validate the final trade area before committing marketing capital.
Housing base
2.07 million
Kentucky housing units, July 1, 2025 Census estimate. A large installed housing stock supports replacement and repair demand but is not roofing-market revenue.
Owner occupancy
68.3%
Owner-occupied housing-unit rate for 2020 – 2024. It is a useful buyer-base proxy, not a conversion rate.
New-build pulse
14,940
Building permits reported for 2025. The canonical business focuses on residential replacement/repair, so new permits are contextual rather than the revenue model.
A Census-based 2023 extraction reports about 255 Kentucky employer roofing establishments and 2,033 employees in NAICS 238160. That supply proxy suggests a fragmented contractor market, but it does not reveal self-employed-only operators, current 2026 capacity, storm-driven temporary entrants or revenue by service mix. The model therefore does not label establishment count as “market size.”
What to validate before choosing an address
- Permit and contractor-registration rules for the principal office and target service counties.
- Local occupational-license tax base and rate; the statewide Base intentionally leaves it unmodeled.
- Supplier delivery radius, dump/tipping fees, material credit terms and storm-season availability.
- Roof-age distribution, insurer claim mix, competitor response time and lead cost by ZIP.
Risk-to-KPI map
- Material inflation → contribution dollars per replacement.
- Lead inflation → marketing cost per won job and estimate-to-close rate.
- Weather downtime → productive crew hours versus paid hours.
- Collections drag → days from completion to final payment and unrestricted cash floor.
Methodology
Sources, method and what still needs a local quote
Research was reviewed on August 29, 2026. Dollar figures are 2026 planning USD unless a source period is stated. Official fees and rules are taken from issuing authorities; occupational wages are government-derived; replacement pricing and trailer pricing are observed market quotes; truck, insurance, repair pricing, payroll burden and several startup allowances are modeled planning assumptions with their limitations stated.
Evidence confidence is highest for Kentucky entity fees, workers' compensation coverage rules, tax-registration guidance, the state sales-tax treatment cited, Census housing statistics and federal fall-protection rules. It is moderate for occupational wages and the three-market replacement-price basket. It is lower/model-dependent for insurance premiums, the $1,100 repair ticket, used work-truck allowance, lead-generation spend and local permit/compliance budget. The largest single uncertainty is the final address: local occupational tax, contractor registration, permit practice and insurer/carrier pricing can materially change both opening cash and monthly margin.

Before using this model as a budget, obtain written quotes for workers' compensation, general liability, commercial auto, truck, trailer, dump/tipping arrangements and material supplier terms; then confirm zoning/home-office status, occupational licensing, contractor registration, job-permit rules and local tax treatment with the issuing city/county. This research is a planning model, not legal, insurance or tax advice.
