Roofing in Illinois

Why Illinois roofing is different

Most Midwestern states leave roofing licensure to counties and municipalities, or they skip it entirely and let a general contractor tag handle everything. Illinois took a different route: a purpose-built statute, a dedicated state license administered by IDFPR, and a standalone exam for limited and unlimited contractors. For a homeowner, that is a gift — the verification step is fast, the record is public, and the line between a real roofer and a truck with ladders is a license number.

The governing statute is the Illinois Roofing Industry Licensing Act, 225 ILCS 335, and it is administered by the Illinois Department of Financial and Professional Regulation (IDFPR). No person may hold out, advertise, or bid as a roofing contractor in Illinois without an active IDFPR license — and the classification on that license tells you exactly what scope of work the contractor is authorized to perform. That is not how it works in Texas, Georgia, or most of the Midwest.

The license has two classifications. A Limited roofing contractor is authorized to perform residential roofing on structures with eight units or fewer. An Unlimited roofing contractor may perform both residential and commercial roofing work statewide, with no unit cap. The qualifying party — the person responsible for day-to-day business activities — must personally sit and pass the IDFPR examination. Limited candidates take the Illinois Residential Roofing Exam; Unlimited candidates take the Residential, Commercial, and Industrial Roofing Exam. Passing score is 70 percent.

Bond and insurance requirements are written into the rules. A Limited licensee must post a $10,000 surety bond and carry at least $250,000 of general liability coverage. An Unlimited licensee must post a $25,000 surety bond and carry at least $500,000 of general liability coverage. Both must carry property damage coverage of at least $250,000. Any contractor who cannot produce both a current license number and a current Certificate of Insurance is not a contractor you should be signing with.

Illinois is also one of the few states that produces a genuine mid-latitude weather mix on the same roof in the same year. A home in Naperville can sit through an April tornado watch, a May hailstorm, a July derecho, and a February ice dam, all of which produce different kinds of roof damage and are treated differently by insurers. The building code now standardizes part of the response: Public Act 103-0510, effective January 1, 2025, requires every Illinois municipality and county to adopt the International Residential Code for residential buildings (outside Chicago, which runs its own code). Before 2025, adoption was a patchwork.

Estimate your Illinois roof cost

Illinois homeowners insurance is harder and pricier than it was two years ago

Illinois did not rewrite its insurance market the way Florida did, but the economics have shifted sharply anyway. Hail frequency has driven loss ratios up, large carriers have pushed through double-digit rate increases, and wind-hail deductible minimums are tightening on renewal. The statutes that matter for a roof claim are mostly untouched — but the leverage a homeowner has depends on knowing them before the adjuster shows up.

The most important statute for a roof claim is 215 ILCS 5/143.1. Illinois requires that any suit-limitation clause in a property insurance policy be tolled from the date you file a proof of loss until the date the insurer denies the claim in whole or in part. Illinois also effectively sets a one-year floor on that clause through the Standard Fire Policy — any provision shorter than 12 months conflicts with statutory minimum language. Translation: your policy may say "suit within 12 months," but the clock stops while the insurer is actively reviewing your claim. The time to litigate does not quietly expire under the adjuster's pen.

If the insurer drags the file or denies without basis, Illinois has real teeth at 215 ILCS 5/155. When a court finds an insurer's delay or denial was "vexatious and unreasonable," the insured can recover reasonable attorney fees, costs, and a statutory penalty up to the greater of 60 percent of actual damages, $60,000, or the excess of the amount owed over what the insurer offered. Section 155 is the reason a paper trail — dated correspondence, photo logs, repair bids — matters. You are building the record a court would review if the claim goes sideways.

Rate environment: State Farm — the largest Illinois homeowners writer — implemented an average 27 percent statewide homeowners rate increase effective August 15, 2025, and required renewing customers to carry a minimum 1 percent wind-and-hail deductible. Allstate filed its own increase totaling nearly 9 percent on more than 200,000 Illinois policies in late 2025. Illinois ranked second in the country for three-year homeowners premium growth, with typical policies up roughly 50 percent over that window. Hail is the driver — Illinois reported $638 million in hail claims in 2024, second only to Texas.

Roof-age underwriting is the other pressure. Illinois does not have a statutory roof-age rule comparable to Florida's 627.7011, so carriers set their own thresholds — typically 15 to 20 years for asphalt — and handle them through nonrenewal or actual-cash-value-only coverage on the roof. If your carrier sends a notice threatening nonrenewal solely on roof age, ask in writing for the underwriting guideline being applied and whether an independent inspection can rebut it. That correspondence is the start of your record.

Verifying a roofing contractor under the Illinois Roofing Industry Licensing Act

Most states do not license roofers at the state level. Texas, Colorado, and Georgia leave it to counties and cities; some states do not license them at all. Illinois is different. Under 225 ILCS 335, every contractor holding out as a roofer in Illinois must carry an active IDFPR license, and the license record is a free public lookup. Skipping this step is how homeowners end up paying cash to a truck that disappears after tear-off.

The two classes are Limited and Unlimited. A Limited licensee can perform residential roofing on any structure up to eight units — a typical single-family, duplex, fourplex, or small multifamily. An Unlimited licensee can perform residential and commercial roofing with no unit cap. The license number is printed on every legitimate contract, vehicle, and business card. If it is missing, stop.

The verification step takes about a minute. IDFPR runs a public license lookup portal at online-dfpr.micropact.com/lookup. Search by the contractor's name or license number. The record shows status (active, inactive, lapsed, suspended, revoked), issue date, expiration, qualifying-party name, and any disciplinary history. Screenshot the page with a timestamp. That single piece of paper is the strongest artifact you can hold onto when comparing bids.

Unlicensed work carries real criminal exposure — for the contractor. Under 225 ILCS 335, a first violation of the Act is a Class A misdemeanor punishable by a fine up to $2,500; a second or subsequent violation is a Class 4 felony punishable by a fine up to $25,000. Each day of unlicensed work is a separate offense. For the homeowner, the consequences are economic rather than criminal: the mechanics-lien rights an unlicensed contractor would otherwise claim are unenforceable, warranty promises from a dissolved unlicensed entity are usually uncollectible, and insurers routinely deny claims on work performed without a required license.

If a contractor offers to waive, discount, credit, or absorb your insurance deductible — or quietly pads the estimate by the deductible amount — that is not a favor. It is the setup for an insurance-fraud claim against you, and it is a pattern Illinois prosecutors have taken seriously. The Illinois Attorney General's Consumer Protection Division, IDFPR's enforcement unit, and the Illinois Department of Insurance all take tips at no cost to the reporter.

Licensing, bonding, and the Chicago overlay

The Illinois license is statewide, but the city of Chicago adds its own registration on top. A contractor working in Chicago must carry both an active IDFPR license and a Chicago Department of Buildings roofing contractor registration. A contractor working in suburban Cook County or downstate needs the IDFPR license plus — depending on the municipality — a local permit-puller or business registration. The state license is the floor; it is never the whole story.

The IDFPR license renews every two years, expiring December 31 of odd-numbered years. The renewal fee, current as of the 2026 cycle, is $125 per two-year period. Renewal requires a current certification of bond and insurance compliance, a designated qualifying party, and payment of the fee. Lapsed licenses trigger automatic suspension — the lookup record will show the status shift, and a "lapsed" or "not renewed" result on the portal is the same answer as "do not hire this contractor."

Chicago registration is separate and runs through the Department of Buildings. The city requires a proctored exam, a $10,000 surety bond, and general liability coverage at the city's current minimum ($1 million per occurrence / $2 million aggregate at last confirmation), plus auto liability and workers' compensation. Annual renewal runs through April 30. Inside the city, no IDFPR license alone lets a contractor pull a re-roofing permit — both registrations must be active.

Outside Chicago, municipalities run the permit step. Cook County suburbs each have their own permit portal; downstate cities — Rockford, Peoria, Springfield, Champaign, Bloomington, Naperville, Aurora, and the Metro East municipalities — publish their own residential permit fee schedules and inspector contacts. The IDFPR license is the qualification to work statewide; the local permit is the authorization to touch a specific roof. Ask the contractor which municipal permit desk they will be filing with, and call that desk once to confirm the contractor is known to them.

A note on penalties for shortcutting the license. Under 225 ILCS 335, each day of unlicensed work is a separate Class A misdemeanor on the first offense and a Class 4 felony on any subsequent offense — $2,500 and $25,000 maximum fines respectively. The Home Repair Fraud Act, 815 ILCS 515, layers criminal exposure on top: home repair fraud involving a contract over $1,000 is a Class 4 felony, and aggravated home repair fraud against an elderly or disabled person is a Class 2 felony. These are the statutes IDFPR's enforcement unit and the Illinois Attorney General's Consumer Protection Division actually use.

Tornadoes, hail, derechos, and ice — all on the same roof

Illinois sits in the convergence zone for four very different kinds of roof-damaging weather. Spring brings tornadoes and severe hail; summer brings derechos and heat-baked UV cycling; winter brings ice dams along the Lake Michigan snow belt and across the northern third of the state. Each one produces a different damage pattern, a different insurance conversation, and a different filing posture — but all of them share one thing: the clock from 215 ILCS 5/143.1 starts running the moment the event happens.

Peak tornado months are April, May, and June; about 60 percent of Illinois tornadoes between 1950 and 2025 occurred in that three-month window, with May the single busiest month. The afternoon-evening window (3 p.m. to 7 p.m.) produces half of all touchdowns. Hail runs on a similar calendar, and Illinois has been among the three most hail-hit states in the country for three consecutive years — 305 severe hail events in 2023, 225 events in 2024. For homeowners, the practical pattern is straightforward: document the roof before hail season, know what your deductible looks like before a storm, and do not wait more than a few weeks to file.

Document before you call anyone. Dated ground-level or drone photos of all roof planes, plus photos of gutters, fascia, and any interior water staining. Check your attic for daylight at deck penetrations. If you have a pre-storm inspection, a prior year's roof condition report, or an HO declarations page that notes roof age, pull those as well. Adjusters weigh documented before/after evidence far more heavily than homeowner recollection, and the paper you gather in the first 72 hours is what carries a claim if the insurer disputes it later.

Red flags specific to Illinois

Illinois has four consumer-protection statutes that stack on top of each other when a roofer misbehaves: the Roofing Industry Licensing Act, the Home Repair and Remodeling Act, the Home Repair Fraud Act, and the Consumer Fraud and Deceptive Business Practices Act. Knowing which statute each red flag trips is how you know which agency to call.

• No IDFPR license number on the bid or contract225 ILCS 335

  Every legitimate Illinois roofer operates under an IDFPR license. The license number should appear on the bid, the contract, the vehicle, and the business card. Absence of a number — or a number that does not resolve on the IDFPR lookup — is a violation of 225 ILCS 335. Each day of unlicensed work is a separate Class A misdemeanor on first offense.

• No written contract, no "Know Your Consumer Rights" pamphlet815 ILCS 513

  Any residential repair over $1,000 must be supported by a written contract with specific disclosures, and the Illinois Attorney General's pamphlet must be handed to you before you sign. A contractor who walks in with a clipboard and a one-page work order for a $12,000 re-roof is violating the Home Repair and Remodeling Act on its face.

• "We'll handle the insurance claim for you"815 ILCS 513/15.1

  Under 815 ILCS 513/15.1, a contractor may not represent a homeowner on an insurance claim, may not file the claim, and may not negotiate the claim. They may submit a written estimate and discuss scope with the adjuster. Anything further is unlicensed public adjusting. "We know how to work the claim" is the pitch this statute was written to stop.

• Offer to waive, credit, or absorb your deductible815 ILCS 505 and 815 ILCS 515

  An insurance deductible is not a negotiable line item a contractor can erase. Any contractor who offers to waive, rebate, discount, or "build in" your deductible is asking you to participate in a fraudulent claim against your insurer. The conduct is actionable under the Illinois Consumer Fraud and Deceptive Business Practices Act (815 ILCS 505) and — if the misrepresentation is material — triggers Home Repair Fraud Act exposure as well.

• Post-storm door-knock pressure to sign "today only"815 ILCS 515 and Illinois AG three-day rule

  Door-to-door solicitation after a storm is not illegal on its own, but pressure to sign a contract on the spot — especially if the contractor refuses to leave the bid so you can compare — is the signature pattern of the Home Repair Fraud Act cases the Illinois Attorney General has pursued. You have a three-business-day right to cancel any at-home-signed contract. That right must be disclosed in writing.

What drives Illinois pricing

Illinois asphalt-shingle replacement tracks close to the national median downstate and runs above median in and around Chicago. The gap is mostly labor, permit complexity, and the ice-and-water shield requirement in the northern half of the state. Understanding which of those apply to your house is the difference between comparing bids fairly and getting talked into a five-figure upsell.

On a typical 1,800-square-foot asphalt-shingle re-roof, downstate Illinois bids generally run $9,000–$15,000. Chicago and the near-suburbs run materially higher — $15,700–$26,800 is the commonly cited range for 2025 — because of the dual-registration requirement, higher prevailing-wage expectations, tighter permit coordination, and the two inspection visits the Chicago Department of Buildings typically requires. The drivers below are the line items that carry the actual price difference, not the metro label.

• Ice-and-water shield at eaves (northern IL required)+$200–$600 material

  The International Residential Code — now mandatory statewide under Public Act 103-0510 as of January 1, 2025, and previously adopted by most northern Illinois municipalities — requires a self-adhering ice barrier extending from the roof edge to at least 24 inches inside the exterior wall line, in any area with a history of ice damming. That covers Chicago, Cook County, the collar counties, Rockford, and most of the state above I-80. Skipping it on a northern-IL bid is a code violation, not a cost-saving shortcut.

• Chicago dual-registration and permit overhead+15–20% total (Chicago jobs)

  A Chicago re-roof requires both an IDFPR license and a Chicago Department of Buildings roofing registration. The city's permit fee, inspection schedule, and prevailing-wage expectations add real cost above downstate jobs. Contractors working inside the city must hold $1M/$2M general liability as part of city registration — coverage meaningfully above the IDFPR minimum and meaningfully above what a suburban-only roofer typically carries.

• Class 4 impact-resistant shingle option+$1,000–$2,500 material (optional, carrier-credit-eligible)

  Illinois is a top-three hail state by claim dollars. Most large carriers — State Farm, Allstate, USAA — offer a premium discount on homeowners policies when the roof is an IR-rated (UL 2218 Class 4) shingle, typically 10–25 percent off the wind-hail portion. Material uplift for Class 4 over standard architectural runs $0.50–$1.25 per square foot installed. On a 20-square roof, that's roughly $1,000–$2,500 more upfront, often paid back in 3–6 years of insurance credit.

Estimated ranges derived from Illinois contractor bid surveys and the Chicago Department of Buildings permit schedule. Individual jobs vary with roof size, pitch, decking condition, and product tier.
