A clear, honest pricing guide from a local contractor homeowners have trusted since 1967.
In Illinois, most roof replacement projects fall within the following general ranges:
• Typical asphalt shingle roof: $9,000 – $18,000
• Impact-resistant or upgraded shingles: $12,000 – $25,000
• Large, steep, or complex roofs: $20,000+
Several factors influence the final cost of a roof replacement, including:
• Roof size and square footage
• Roof pitch and steepness
• Tear-off versus roof overlay
• Condition of the roof decking
• Shingle type and material choice
• Ventilation and code upgrades
• Number of penetrations (chimneys, skylights, valleys)
• Access and overall roof complexity
Roof Replacement Cost by Material Type
Asphalt shingles are the most common roofing material in Illinois because they offer a balance of affordability, durability, and design options. For most homes, asphalt shingles provide reliable protection and a solid lifespan when properly installed and ventilated.
Impact-resistant shingles are designed to withstand hail and severe weather and may qualify some homeowners for insurance premium discounts. While they cost more upfront than standard shingles, they can offer added protection and long-term value in storm-prone areas.
Homeowners are often surprised by how much roofing quotes can differ from one contractor to another. In many cases, the difference is not the materials themselves, but what is included — or excluded — from the scope of work.
• Proper tear-off and disposal
• Decking inspection and replacement if needed
• Ventilation upgrades to meet code
• Licensed, insured labor
• Jobsite protection and cleanup
• Workmanship and installation warranty
The lowest bid is often missing critical steps that may not be obvious until problems appear years later.

In some situations, a roof repair may be the most cost-effective option, especially when damage is isolated or the roof is relatively new. In other cases, replacement makes more sense when the roof is near the end of its lifespan or experiencing widespread issues.
The right choice depends on age, extent of damage, long-term cost, and whether repairs will meaningfully extend the roof’s life.

Many homeowners choose to finance roof replacement rather than paying the full cost upfront. Financing can make it easier to move forward with needed work while spreading payments over time.
Financing options vary by project and approval, and a qualified contractor can explain what programs may be available during the inspection process.
A roof replacement is a long-term investment, and warranty coverage plays a significant role in overall value. Beyond materials, proper installation, ventilation, and workmanship all affect how long a roof will perform.
Understanding what is covered, how warranties work, and who stands behind them can help homeowners make a more confident decision that goes beyond upfront cost.

Roof replacement costs in Illinois typically range from several thousand dollars to over twenty thousand dollars, depending on roof size, material choice, and project complexity. The most accurate way to determine cost is through an on-site inspection that accounts for these variables.
Insurance may cover roof replacement if damage is caused by a covered event such as hail or wind. Coverage depends on your policy, roof age, and extent of damage, which is why a professional inspection is often the first step.
Most asphalt shingle roofs in Illinois last between 20 and 30 years, depending on installation quality, ventilation, and exposure to severe weather. Impact-resistant materials may offer longer performance in storm-prone areas.
Most roof replacements are completed in one to two days, depending on roof size, complexity, and weather conditions. Larger or more complex projects may take longer.
In some cases, repairs can extend the life of a roof, especially when damage is limited. Replacement is often the better option when a roof is near the end of its lifespan or has widespread issues affecting performance.
