How to Start a Roofing Business in Illinois After Getting Licensed

You passed the exam. You've got your Illinois roofing contractor license from IDFPR. Now what?

A license lets you work legally. It doesn't give you a business. Plenty of licensed roofers never make the jump because the paperwork side intimidates them. Don't let it. Starting a roofing business in Illinois is straightforward — you just need to knock out the steps in the right order.

This guide is for the roofer who's ready to stop working for someone else and start running their own outfit. No startup jargon. No "unlock your potential." Just the checklist, the costs, and the order of operations.

1. Form Your Business Entity

Before you sign a single contract or bid a single job, you need a legal business structure. In Illinois, you've got three realistic options:

• Sole proprietorship — Easiest to set up. Zero paperwork. Also zero liability protection. If someone sues you, they're suing you — your house, your truck, your savings. For a roofer, this is a terrible idea.
• LLC (Limited Liability Company) — The smart choice for most roofing contractors. It separates your personal assets from your business liabilities. If the business gets sued, your personal assets stay protected (assuming you run the LLC properly). Reasonable cost, simple to maintain.
• S Corporation — Same liability protection as an LLC with different tax treatment. Makes sense when you're pulling in serious revenue and want to optimize how you pay yourself. Overkill for most startups.

Why an LLC Is the Right Call for Most Roofers

You're climbing ladders and walking on 8/12 pitches. Accidents happen. If your roofing business is an LLC and something goes wrong, the lawsuit targets the business — not your personal assets. A sole proprietorship offers none of that. Don't risk everything you own to save $150 on a filing fee.

The Illinois Secretary of State charges $150 to file your Articles of Organization online ($175 if you file by paper). Processing takes about 10 business days for online filings. You'll need:

• A business name that's not already taken in Illinois (search on the Illinois SOS business search)
• A registered agent with a physical Illinois address (this can be you, or you can hire a service for $50–$150/year)
• A credit card for the filing fee

Once you're approved, the state emails you your Articles of Organization. Print them. Save them. You'll need them to open a bank account.

2. Get Your EIN and State Tax Registration

Your EIN (Employer Identification Number) is your business's Social Security number. You get it from the IRS, it's free, and it takes about 5 minutes online. Go to IRS.gov, search "EIN," and follow the prompts. You'll have your number before your coffee gets cold.

Next, register with the Illinois Department of Revenue through MyTax Illinois. If you're selling and installing roofing materials, you need to collect and remit Illinois sales tax. The state wants its cut, and they don't mess around with contractors who skip this step. Registration is free.

While you're at it, check whether your city or county requires a local business license. Chicago, Aurora, Naperville, Rockford — many municipalities have their own registration requirements separate from the state. A 10-minute call to your city clerk's office saves you a headache later.

3. Insurance: What the State Requires, and What You Actually Need

Illinois doesn't just suggest insurance for roofing contractors — it's written into the law. Section 9 of the Illinois Roofing Industry Licensing Act (225 ILCS 335/9) spells out exactly what you need to carry before you can legally operate. Here's the breakdown.

Surety Bond

Every licensed roofing contractor in Illinois must file a surety bond with IDFPR. The bond amount depends on your license type:

• Residential license: $10,000 bond
• Unlimited license: $25,000 bond

Important: you're not paying $10,000. The bond premium — what you actually pay — is typically $100 to $500 per year, depending on your credit. If your credit is rough, you might pay more. But you're never writing a five-figure check up front.

General Liability Insurance

Illinois requires a minimum of $500,000 in general liability coverage. This protects you when something goes wrong on the job — property damage, bodily injury, the usual nightmares. For a solo residential operation, expect to pay $1,500 to $4,000 per year, depending on your revenue, location, and claims history.

Ask your agent about higher limits. $500,000 is the state minimum, but many general contractors and commercial clients require $1 million or $2 million before they'll let you on site. If you plan to bid commercial work, price $1M/$2M coverage from day one.

Workers' Compensation Insurance

Illinois is strict on this one. Under the Illinois Workers' Compensation Act (820 ILCS 305), any employer with one or more employees must carry workers' comp. There's no "small employer exemption" in Illinois. If you hire a single laborer, you need coverage.

Roofing is classified as high-hazard work, so your rates will be higher than a desk job — roughly $450+ per employee per month. Even if you're a one-man show with no employees right now, get a quote so you're not blindsided when you grow.

Commercial Auto Insurance

Your personal auto policy won't cover you when you're hauling materials to a job site. If your truck or van is used for business — even part-time — you need a commercial auto policy. It's not an IDFPR requirement, but it's common sense. One accident while carrying a load of shingles, and your personal insurer can (and will) deny the claim.

Rough budget: $1,500 to $3,000 per vehicle per year for commercial auto in Illinois.

4. Open a Business Bank Account and Set Up Your Books

Do not run your roofing business through your personal checking account. It's not just messy — it can pierce the liability protection your LLC gives you. A separate business account keeps your books clean and makes tax time survivable.

What you need to open a business bank account:

• Your state-approved Articles of Organization
• Your EIN letter from the IRS
• Your Illinois roofing contractor license
• Your driver's license

For accounting, don't overcomplicate it. QuickBooks or Wave (free) will handle invoices, expenses, and taxes for a small roofing operation. Pick one, learn the basics, and track every dollar from day one. Your CPA will thank you, and you'll save thousands in overlooked deductions.

5. Local Permits and Municipal Requirements

Your state license says you can roof in Illinois. Your local municipality says you need a permit for this specific job at this specific address. Every city and county is different. Some require a permit for every residential reroof. Others only require it above a certain square footage. A few have no permit requirements at all.

Chicago and the collar counties are the strictest. Chicago requires a separate city contractor registration on top of your state license, plus job-specific permits through the Department of Buildings. Cook, DuPage, Lake, and Will counties each have their own rules. Call the local building department before you bid a job. The 10-minute call saves you the $500+ fine.

Also worth knowing: Illinois roofing permits increasingly require compliance with the Illinois Energy Code (based on ASHRAE 90.1). That means minimum R-values for commercial roof assemblies and specific insulation requirements. If you're doing commercial work, know the energy code.

6. Getting Your First Jobs

You're licensed, insured, bonded, and registered. Now you need customers. Here's what works for new roofing businesses in Illinois:

• Let everyone know. Text your old crew, former bosses, subcontractor contacts, and every general contractor you've ever worked with. Most first jobs come from people who already know your work.
• Claim your Google Business Profile. When someone searches "roofer near me" or "roofing contractor Illinois," Google shows local results first. A complete profile with your license number, service area, and a few photos puts you on the map — literally.
• Get on the major contractor directories. HomeAdvisor, Angi, and Thumbtack bring leads. The lead fees sting, but when you're starting out and don't have a reputation yet, they fill the pipeline.
• Talk to insurance adjusters. Illinois gets hail, wind, and ice damage. Insurance adjusters need reliable roofers to handle claims. Build relationships with a few local adjusters and you'll get steady referral work — especially after storm season.
• Build a simple website. Doesn't need to be fancy. Your license number, your service area, what you do, how to reach you. That's it. Cost: a few hundred bucks once, or build it yourself with Squarespace or Carrd for less.

Don't compete on price. The unlicensed guys will always underbid you. Compete on being licensed, insured, and professional. Homeowners who care about quality will pay for peace of mind. The ones who only care about the lowest number aren't your customers anyway.

FAQ: Starting a Roofing Business in Illinois

Do I need an LLC to start a roofing business in Illinois?

No, the state doesn't require an LLC specifically — but you'd be foolish not to form one. A sole proprietorship offers zero liability protection, and roofing is dangerous work. LLC formation costs $150 online in Illinois. That's cheap insurance for your personal assets.

How much does it cost to start a roofing business in Illinois after getting licensed?

Beyond your licensing costs (exam fee, application fee, study materials), budget roughly $3,000 to $7,000 for your first year. That covers LLC formation ($150), EIN (free), surety bond ($100–$500), general liability insurance ($1,500–$4,000), workers' comp if hiring, and basic tools and marketing. You can start lean and add expenses as revenue comes in.

Can I operate a roofing business in Illinois as a sole proprietor?

Technically, yes. Practically, it's a bad decision. As a sole proprietor, there's no legal separation between you and your business. If a job goes wrong — injury, property damage, lawsuit — your personal assets are on the line. For $150, form the LLC and protect yourself.

What insurance is absolutely required for Illinois roofing contractors?

Three things, per the Illinois Roofing Industry Licensing Act: (1) a $10,000 surety bond for residential ($25,000 for unlimited), (2) $500,000 minimum general liability insurance, and (3) workers' compensation insurance if you have any employees. Commercial auto isn't legally required but is standard practice for anyone driving to job sites.

Do I need a local business license in addition to my state roofing license?

It depends on your city and county. Chicago requires separate city registration. Many other municipalities do too. Check with your local city clerk or building department. Also register with the Illinois Department of Revenue through MyTax Illinois if you're selling materials (which you are — you're a roofer).

How long does it take to get everything set up and start bidding jobs?

If you move fast: 2 to 4 weeks. LLC online filing is about 10 business days. Your EIN is instant. Insurance quotes come back in 24-48 hours. Bond approval is usually same-day or next-day if your credit is decent. The bottleneck is usually waiting on yourself to pull the trigger — not the government.
