Full Cost Breakdown

Cost Category	Low	Medium	High	Notes
Truck & Trailer	$5,900	$23,600	$70,800	A strong pickup truck and flatbed trailer are the minimum. A dump trailer is a meaningful four-figure capital purchase that saves significant labor on tearoff disposal.
Roofing Tools & Safety Equipment	$3,540	$11,800	$35,400	Fall protection (harnesses, anchors, guardrails) is OSHA-mandated. Plan a meaningful four-figure cost per crew for proper fall protection equipment.
Contractor License & Bond	$590	$2,950	$9,440	Roofing license requirements vary enormously by state. Florida requires roofer-specific license; many states require only general contractor license.
Insurance	$5,750	$17,250	$57,500	Roofing is one of the most dangerous trades — workers comp is mandatory and one of the most expensive premiums in the construction trades. Premiums scale with payroll and claims history.
Roofing Materials Deposit	$2,360	$9,440	$29,500	Collecting a meaningful customer deposit (typically a third to half of contract value) before ordering materials dramatically reduces working-capital requirements.
Dumpster & Disposal Account	$590	$2,360	$7,080	A standard 15-yard dumpster is a low-to-mid three-figure per-job cost. Establishing an account ensures priority delivery during busy seasons.
Marketing & Storm Chasing	$1,180	$5,900	$17,700	Post-storm canvassing is the most cost-effective roofing marketing. After any hail or wind event, knock doors in affected areas.
Safety Equipment & OSHA Compliance	$590	$1,770	$4,720	Roofing is one of the highest-risk trades — OSHA violations are common and costly.
Total Startup Cost	$20,500	$75,070	$232,140	Required costs only

Licenses & Permits in Washington

General Business License

Washington State requires most businesses to obtain a Unified Business Identifier (UBI) through the Business Licensing Service (BLS) of the Department of Revenue. Washington has no state income tax, but does have a Business and Occupation (B&O) tax applied to gross receipts, which is unique among US states. Additionally, businesses must register for the B&O tax and any applicable retail sales tax. Many cities require a separate city business license endorsed onto the state license through a streamlined endorsement system.

Common Mistakes to Avoid

1
Skimping on fall protection — OSHA per-violation penalties for fall-protection deficiencies are substantial and compound across job sites
2
Not requiring insurance certificates from subcontractors — their injuries become your liability
3
Accepting insurance jobs without understanding the supplement process — leaving money on the table on every claim
4
Undercharging — residential roof replacement is a multi-day, multi-person, materials-heavy job; pricing must cover materials, labor, dumpster, supervision, and reasonable margin
5
Not offering financing — most customers need to finance roof replacement; offering it closes more sales

Frequently Asked Questions

Starting a roofing company spans a wide range. A solo roofer with basic tools, a used truck, and proper insurance can start in the low-to-mid five figures. A four-to-six person crew with a truck, trailer, full tool set, and marketing budget requires meaningfully more — well into the six figures. A larger company with multiple crews requires materially more capital. Use the calculator on this page to model your specific scenario.

Residential roof replacement jobs net a meaningful four-figure profit per job depending on size and materials. A typical 2,000 sq ft shingle replacement contract is a low-to-mid five-figure ticket with materials and labor consuming the bulk of revenue. Net margins are healthy with efficient crews and good material pricing.

Licensing varies dramatically by state. States like Florida, Texas, and California require specific roofing contractor licenses. Many states require only a general contractor license. Some states have no roofing license requirements at all. All states require general liability insurance and workers compensation to legally operate.

Top sources: storm damage canvassing after hail/wind events — the most profitable immediate channel, Google search ('roofing contractor near me'), referrals from satisfied customers and real estate agents, Google Ads for 'roof replacement' keywords, and relationships with insurance adjusters and restoration companies.

Roofing peaks in spring and fall when weather is mild. Summer heat limits outdoor work hours. Winter work is restricted in northern states by cold and snow. Storm season (spring-fall in many regions) drives the most profitable emergency replacement work. Companies in storm-prone areas (Oklahoma, Kansas, Texas, Colorado) can do enormous volume following major hail events.
