Licensed roofing contractors in Illinois must hold a Roofing Contractor License issued by the Illinois Department of Financial and Professional Regulation (IDFPR). This license requires contractors to pass an examination demonstrating knowledge of roofing materials, building codes, safety standards, and business practices. The exam covers topics like proper installation techniques, weather protection, ventilation requirements, and compliance with the Illinois Building Code. Licensed contractors must also carry workers' compensation insurance and maintain proof of their credentials.

General contractors with roofing divisions represent another category. These contractors hold a General Contractor License but may specialize in roofing work as part of broader construction services. General contractors often manage larger projects that include roofing alongside other building components like structural repairs or full renovations.

Residential roofing specialists focus specifically on homes and small residential buildings. They typically have extensive experience with common residential roofing materials like asphalt shingles, architectural shingles, metal roofing, and tile. Commercial roofing specialists work on larger buildings and often handle flat roofs, built-up roofing systems, TPO membranes, and other commercial-grade materials.

Chicago also has roofing inspectors and estimators who may not perform installation work themselves but assess roof conditions and provide cost projections. Understanding these different roles helps clarify what services you may need.

Practical Takeaway: Before hiring a contractor, ask about their specific license type, what it covers, and how many years they have worked in their particular roofing specialty. Request to see their current license and proof of insurance.

Common Roofing Materials Used in Chicago Homes and Buildings

The roofing material you choose affects durability, cost, maintenance requirements, appearance, and how well your roof performs in Chicago's climate. Chicago experiences significant weather variations—hot summers, cold winters with snow and ice, spring storms with heavy rain, and occasional hail. Understanding material options helps you make informed decisions about what might work for your property.

Asphalt shingles remain the most widely used roofing material in Chicago. They cost between $3 and $5 per square foot (a square equals 100 square feet) and typically last 15 to 20 years. Standard asphalt shingles come in three-tab and architectural styles. Three-tab shingles are thinner and less expensive. Architectural shingles appear thicker with more dimension and generally last longer. Both types come in various colors to match different home styles. Asphalt shingles handle Chicago winters reasonably well, though extreme cold and ice dams can shorten their lifespan.

Metal roofing has grown in popularity in the Chicago area. Standing seam metal roofs cost between $6 and $12 per square foot and can last 40 to 60 years. Metal reflects sunlight, which reduces cooling costs in summer. Metal roofs handle snow and ice well because snow slides off more easily than from asphalt shingles. They are also fire-resistant and resist wind damage better than shingles. The main drawbacks are higher upfront cost and noise from rain and hail unless proper underlayment is installed.

Slate and tile roofing represents a premium option costing $10 to $25 per square foot or more. These materials can last 50 to 100+ years and provide a distinctive appearance. However, they are heavy, require strong structural support, and need specialized contractors for installation and repair. Chicago has some historic neighborhoods where slate and tile roofs are common.

Flat roofing systems cover many Chicago commercial buildings and some residential properties. Common flat roof materials include TPO (thermoplastic polyolefin), EPDM rubber, modified bitumen, and built-up roofing. Each has different lifespans, costs, and maintenance requirements. Flat roofs require proper drainage and regular inspection to prevent water pooling.

Practical Takeaway: Consider your budget, the age of your current roof, and local weather patterns when evaluating materials. Get quotes for at least two different material options to understand cost differences and expected lifespans.

Roof Inspection and Assessment Process

A thorough roof inspection is the foundation for understanding your roof's condition and determining what repair or replacement work may be needed. Professional inspectors use systematic methods to evaluate the roof surface, flashing, gutters, ventilation, and underlying structure. Knowing what a proper inspection includes helps you ask the right questions and understand what contractors are recommending.

Visual surface inspection involves examining the roof from the ground and from above for signs of damage, wear, or deterioration. Inspectors look for missing, cracked, or curling shingles; areas where shingles are lifting; visible cracks or splits; granule loss (bald spots where the protective coating has worn away); and discoloration indicating algae or moss growth. They check for damaged or corroded flashing around chimneys, vents, skylights, and roof penetrations. Flashing failures are among the most common sources of roof leaks because water can seep behind the flashing even when the roofing material itself is intact.

Structural and interior inspection examines the attic space and interior of the building for signs of water damage. Inspectors look for water stains on rafters and decking, mold growth, condensation, wood rot, and pest damage. Proper ventilation in the attic space is critical to roof longevity. Inadequate ventilation traps moisture and heat, which accelerate deterioration. Inspectors assess whether attic vents are functioning properly and whether soffit vents and ridge vents are clear of debris.

Gutter and drainage assessment looks at gutters, downspouts, and how water flows away from the building. Clogged or damaged gutters prevent proper water drainage and can cause water to back up under the roofing material. Downspouts should direct water at least 4 to 6 feet away from the foundation to prevent foundation problems.

Age assessment is important because roofing materials have predictable lifespans. An inspector can often determine approximate age by examining the materials and installation style. Knowing the age helps predict when replacement might be necessary. Many insurance companies require roof replacement after a certain age, even if the roof is still functional.

Professional inspectors typically provide a written report documenting findings, photographs, and recommendations. This report becomes valuable documentation for insurance claims, real estate transactions, and planning future maintenance.

Practical Takeaway: Schedule a professional inspection every 3 to 5 years or after severe weather events. Ask the inspector to provide a written report with photos and priority recommendations for repairs.

Roof Repair Versus Replacement Decision-Making

One of the most significant decisions property owners face is determining whether a roof should be repaired or replaced. This choice has major financial implications and depends on multiple factors. Understanding these factors helps you make decisions aligned with your property's long-term maintenance needs.

Cost comparison forms the obvious starting point. Minor repairs might cost $200 to $1,000 for things like replacing a few damaged shingles, resealing flashing, or cleaning gutters. More extensive repairs addressing larger damaged areas, significant flashing issues, or multiple problem spots can range from $2,000 to $10,000 or more. Full roof replacement typically costs $8,000 to $25,000 or more depending on square footage, material choice, and complexity. When repair costs approach 50 percent of replacement cost, replacement often becomes the more sensible choice because you eliminate ongoing problems.

Roof age is a critical factor. Most asphalt shingle roofs last 15 to 20 years. If your roof is 15 to 20 years old or older, replacement is usually the better option even if it currently seems functional. Older roofs become increasingly prone to problems, and repairs become more frequent. Materials like metal, tile, or slate can last 40 to 60 years or longer, which changes the repair versus replacement calculation.

Extent of damage determines whether repair is viable. If damage is localized to one section or a few specific areas, repair may be appropriate. If damage is widespread across multiple sections or the
