How to start or buy a roofing, siding & gutter contracting business

High-ticket residential and commercial roof replacement, repair, seamless gutter, and siding contractor operating an asset-light sales, project-management, and supplier-drop model.

Startup investment: $45,000–$165,000
Typical annual revenue: $750,000–$3,500,000
SDE (Seller’s Discretionary Earnings) Margin
Total pre-tax cash flow available to a full-time owner-operator as a % of annual revenue: Net Profit + Owner’s Salary/Draws + Interest, Taxes, Depreciation & Amortization (EBITDA) + verified one-time owner add-backs.: 15%–25% SDE margin
Resale Valuation Multiple
Typical market purchase price of an established operating business expressed as a multiple of annual Owner SDE (e.g., 2.5× SDE on $200,000 cash flow = $500,000 valuation).: 2.2x–3.6x SDE
Typical time to breakeven: 3–8 months

Three paths into this business: Start Independent vs. Buy Existing vs. Franchise for Roofing, Siding & Gutter Contracting

Path 1 · Build from Scratch

Start Independent

$45,000–$165,000

Ongoing royalties: 0% ongoing franchise royalty
Time to breakeven: 3–8 months
Tradeoffs: 100% control over pricing, vendor selection, and territory with 0% ongoing royalties—preserving the full 15%–25% SDE margin target owner cash flow once ramped. Capital is concentrated upfront in Wrapped Inspection Trucks, Drones & Safety/Ladder Equipment ($20,000–$75,000) and Roofing General Liability Insurance, Licensing & Working Capital ($11,000–$43,000); Required compliance includes State/Municipal Roofing Contractor License (3–8 months typical breakeven).

Path 2 · Acquire Cash Flow

Buy an Existing Resale

2.2x–3.6x SDE ($225,000–$2,800,000)

Ongoing royalties: 0% ongoing franchise royalty (if independent)
Timeline: 30–90 days closing (immediate Day-1 cash flow)
Tradeoffs: Immediate Day 1 revenue (typically $750,000–$3,500,000 for established operators) with trained staff, permits, and vendor accounts in place. Priced at 2.2x–3.6x SDE (Retail re-roofing and commercial flat-roof maintenance businesses command higher multiples than pure storm-chasers), typically financed via SBA 7(a) with 10%–20% down. Priority due diligence: Distinguish steady local retail/aged-roof replacement revenue from one-time hail/hurricane storm spikes.

Path 3 · Franchise System

Buy a Franchise

$73,878–$489,775

Ongoing royalties & fees: 5%–7% of Gross Sales + 2% marketing
Disclosed FDD median brand revenue: $774,915 (across 8 catalog brands)
Tradeoffs: Turnkey brand recognition, national vendor contracts, and playbooks across 8 FDD systems (including Budget Blinds, Mr. Handyman, Five Star Painting), but ongoing royalties and ad fund fees (5%–7% of Gross Sales + 2% marketing) come directly out of top-line gross sales and compress net owner take-home compared with an independent roofing, siding & gutter contracting business.

SBA 7(a) underwriting & payback takeaway:

At $2,150,000 revenue and 20% SDE margin ($430,000/yr pre-debt cash flow), buying an existing roofing, siding & gutter contracting business at 2.9× SDE ($1,247,000) generates $258,371/yr from Day 1 (2.51× DSCR), giving an immediate $57,823 Year-1 cash-flow advantage over building from scratch during a 6-month ramp-up. Once ramped in Year 2+, building from scratch ($105,000 CapEx) nets $415,548/yr (29.75× DSCR). By comparison, a 5% gross-sales franchise royalty on $2,150,000 revenue deducts $107,500/yr directly from owner cash flow.
