Key Takeaways:
Choosing the wrong roofing contractor in Illinois can cost you thousands of dollars in repairs, legal liability, and code violations. With Illinois implementing statewide building codes in 2025 and OSHA issuing six-figure penalties to non-compliant roofing contractors, homeowners face higher stakes than ever when selecting someone to work on their roof. Illinois law requires all roofing work to be performed by state-licensed contractors, yet unlicensed operators continue to target unsuspecting homeowners with low bids and aggressive sales tactics.
The difference between hiring a properly licensed, insured contractor and falling victim to an unlicensed operator can mean the difference between a successful project and a costly disaster involving voided warranties, insurance claims, worker injuries, and substandard work.
This guide walks you through the essential steps to verify contractor credentials, understand permit requirements, recognize safety compliance, and avoid the red flags that signal potential problems before they become expensive mistakes.
Illinois law mandates that only state-licensed contractors perform roofing work. The Illinois Department of Financial and Professional Regulation (IDFPR) issues two license types based on project scope, with specific requirements for qualifying parties, insurance, and bonding.
| License Type | Project Scope | Property Limitations | Use Cases |
| Limited | Residential only | 8 units or fewer | Single-family homes, small apartments, townhouses |
| Unlimited | All property types | No restrictions | Residential, commercial, industrial, institutional |
Both licenses require the same application process, qualifying party designation, and insurance requirements. The only difference is project scope limitations.
Illinois licensing protects consumers from unqualified contractors and ensures work meets safety standards. The Illinois Roofing Industry Licensing Act makes unlicensed roofing work illegal, with violations potentially classified as Class 4 felonies. Licensed contractors must carry insurance, pass examinations, and maintain active status through the IDFPR system.
Licensing also establishes accountability. Licensed contractors face license suspension or revocation for violations, creating financial incentives for quality work and regulatory compliance.
Verification takes five minutes and prevents costly mistakes. The IDFPR online portal provides real-time license status, while cross-referencing contract information ensures authenticity.
Alternative: Call IDFPR at 800-560-6420 for phone verification.
Mismatched information indicates potential fraud or identity theft.
Active status confirms the contractor is legally authorized to perform roofing work in Illinois. It means they've met examination requirements, carry required insurance, and maintain good standing with IDFPR.
Expired, suspended, or revoked licenses indicate the contractor cannot legally work. Hiring unlicensed contractors exposes homeowners to liability for worker injuries, code violations, and substandard work with no regulatory recourse.
Illinois licensed roofing contractors must carry workers' compensation and general liability insurance. These policies protect homeowners from financial liability if workers are injured or property damage occurs during roofing projects.
Workers' compensation covers medical expenses and lost wages for employees injured on job sites. Illinois law requires this coverage for all roofing contractors with employees. Without it, homeowners become liable for worker injuries, potentially facing lawsuits for medical bills, rehabilitation costs, and lost income.
This insurance also covers contractor employees working on your property, eliminating your exposure to workplace injury claims that could reach six figures for serious accidents.
General liability protects against property damage and third-party injuries caused by roofing operations. Coverage includes damage to your home, neighboring properties, vehicles, and landscaping during construction. It also covers injuries to non-employees, such as homeowners or visitors.
Minimum coverage amounts vary by license type, but reputable contractors typically carry $1 million or more in general liability protection to handle major damage claims.
Never accept expired certificates or verbal promises of insurance coverage.
Illinois implemented statewide building codes on January 1, 2025, standardizing permit requirements across municipalities. While local jurisdictions manage permits, their codes must now meet or exceed state standards based on International Code Council regulations.
Permits Required:
Permits Not Required:
Requirements vary by municipality. Always check with local building departments before starting work.
| Municipality | Permit Cost Range | Fee Structure | Notes |
| Chicago | $302 - $5,000+ | Construction factor × scope × area | $302 minimum, Express Program available |
| Cook County | $100 - $500+ | $100 residential/$500 commercial deposit | Digital submission required |
| Effingham | $100 - $400+ | $20 per 100 sq ft, $100 minimum | Up to 20,000 sq ft |
| Normal | $20 - $50+ | $20 base + $4 per unit | Varies by property type |
| Bloomington | $104 - $292+ | Sliding scale by project value | $10,001-$50,000 range |
Additional fees for inspections, plan reviews, and technology charges may apply.
Working without required permits violates Illinois building codes and municipal ordinances. Consequences include stop-work orders, fines, and forced removal of completed work. Insurance companies may deny claims for unpermitted work, and open permits create problems during home sales.
Homeowners remain liable for permit violations even when contractors fail to obtain them. The safest approach is to confirm permit requirements with local building departments before work begins.
OSHA enforces federal safety standards, while the Illinois Department of Labor covers state/local government workplaces. Both agencies focus heavily on fall protection, issuing substantial penalties to non-compliant contractors across Illinois.
OSHA requires fall protection for workers on roofs 6 feet or more above lower levels. Acceptable protection includes personal fall arrest systems (harnesses and lanyards), guardrail systems, or safety nets. Contractors must provide proper equipment and ensure workers receive fall protection training.
Recent OSHA updates, effective July 2025, strengthen enforcement and increase penalties for violations. Contractors failing to provide adequate fall protection face citations, work stoppages, and substantial fines that can exceed $250,000 for repeat violations.
Absence of this equipment indicates an unprofessional or non-compliant contractor.
| Violation Type | Penalty Range | Recent Illinois Examples |
| Serious Violations | Up to $16,131 each | Standard fall protection failures |
| Willful/Repeat Violations | Up to $161,323 each | Contractors with a violation history |
| Recent Major Penalties | $250,000+ total | Fino Exterior ($262,000), Corner Construction ($266,175) |
| Failure to Abate | $16,131 per day | Ongoing violations beyond the correction deadline |
| Multiple Violations | Cumulative penalties | 595 Construction ($287,000 for 8 violations) |
These penalties demonstrate OSHA's aggressive enforcement against contractors who repeatedly ignore safety requirements, protecting both workers and homeowners from liability exposure.
Proper contracts protect homeowners from disputes, cost overruns, and substandard work. Illinois law requires specific information in roofing contracts, while recognizing common scam tactics helps avoid fraudulent contractors.
Missing elements indicate unprofessional contractors or potential legal issues.
These tactics target vulnerable homeowners and often result in substandard work or abandonment.
Focus on value rather than the lowest price. Compare material quality, warranty terms, project timelines, and included services like cleanup and permit handling. Verify each contractor's license status and insurance coverage before price comparison.
Extremely low bids often indicate corner-cutting on materials, labor, or safety requirements. The best value typically comes from mid-range bids that demonstrate proper planning, quality materials, and realistic timelines while maintaining competitive pricing.
Selecting the right contractor requires systematic research, thorough questioning, and careful documentation review. This final step combines all verification processes into a comprehensive selection framework.
Focus on recent work and consistent patterns rather than isolated complaints.
Document all answers and verify claims independently.
Maintain copies of all documents throughout the project.
Start by obtaining multiple bids from licensed contractors, then systematically verify each contractor's credentials through IDFPR and insurance companies. Research their reputation through references and online reviews, asking specific questions about workmanship and reliability. Compare bids based on value rather than price alone, considering materials quality, warranty terms, and project timelines. Select the contractor offering the best combination of credentials, reputation, and value, then finalize a comprehensive written contract including all required Illinois legal elements before any work begins.
These steps protect against legal violations and ensure quality completion meeting Illinois standards.
