Full Cost Breakdown

Cost Category	Low	Medium	High	Notes
Truck & Trailer	$6,750	$27,000	$81,000	A strong pickup truck and flatbed trailer are the minimum. Dump trailers ($5,000-$12,000) save significant labor on tearoff disposal.
Roofing Tools & Safety Equipment	$4,050	$13,500	$40,500	Fall protection (harnesses, anchors, guardrails) is OSHA-mandated. Budget $1,500-$4,000 for proper fall protection per crew.
Contractor License & Bond	$675	$3,375	$10,800	Roofing license requirements vary enormously by state. Florida requires roofer-specific license; many states require only general contractor license.
Insurance	$6,250	$18,750	$62,500	Roofing is one of the most dangerous trades — workers comp is mandatory and expensive. Budget $5,000-$20,000/year for a small crew.
Roofing Materials Deposit	$2,700	$10,800	$33,750	Collect 30-50% deposit from customers before ordering materials. This dramatically reduces capital requirements.
Dumpster & Disposal Account	$675	$2,700	$8,100	A 15-yard dumpster costs $300-$600 per job. Establishing an account ensures priority delivery during busy seasons.
Marketing & Storm Chasing	$1,350	$6,750	$20,250	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	$675	$2,025	$5,400	Roofing is one of the highest-risk trades — OSHA violations are common and costly.
Total Startup Cost	$23,125	$84,900	$262,300	Required costs only

Licenses & Permits in California

General Business License

California does not have a statewide general business license, but most cities and counties require a local business license or business tax certificate. Businesses must register with the California Secretary of State for entity formation, obtain a seller's permit from the California Department of Tax and Fee Administration if selling taxable goods, and register with the EDD for payroll taxes if employing workers. San Francisco, Los Angeles, and other major cities have their own business registration and tax requirements.

AB 2221 (2022) expanded rights for home-based food businesses under the Homemade Food Operations Act. Some cities, including Los Angeles, have updated their home occupation rules to allow more types of businesses post-pandemic.

Common Mistakes to Avoid

1
Skimping on fall protection — OSHA fines for safety violations run $1,000-$15,000 per violation
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 should clear $3,000-$10,000 profit depending on size
5
Not offering financing — most customers need to finance roof replacement; offering it closes more sales

Frequently Asked Questions

Starting a roofing company costs $15,000 to $180,000. A solo roofer with basic tools, a used truck, and proper insurance can start for $15,000-$35,000. A 4-6 person crew with a truck, trailer, full tool set, and marketing budget typically costs $50,000-$120,000. A larger company with multiple crews can exceed $180,000.

Residential roof replacement jobs net $2,000-$8,000 profit depending on size and materials. A 2,000 sq ft shingle replacement contract runs $8,000-$15,000 in revenue. Materials and labor cost $4,000-$9,000. Net margins of 25-40% are achievable 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: (1) storm damage canvassing after hail/wind events — the most profitable immediate channel, (2) Google search ('roofing contractor near me'), (3) referrals from satisfied customers and real estate agents, (4) Google Ads for 'roof replacement' keywords, and (5) 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.
