New Roof Cost in Illinois by Square Footage
Illinois has a median home size of 1,700 square feet, which is notably smaller than the national average of 2,411 square feet, according to the National Association of Home Builders. This smaller average reflects the state’s mix of historic urban homes and compact suburban developments.
Your home’s square footage is one of the primary drivers of roofing costs, as larger homes require more materials, longer installation times, and often more complex roof designs. However, the relationship between square footage and price isn’t always proportional. Smaller homes may have higher per-square-foot costs due to installers charging minimum project fees and fixed costs of equipment setup.
Illinois homes often feature moderate roof pitches that are suitable for shedding snow and rain, although urban areas may have steeper pitches for aesthetic appeal. The state’s diverse housing stock means roof complexity varies widely, which can affect both material needs and labor costs.
The table below shows the average cost of an Illinois roof replacement based on the square footage and estimated number of stories of a home:
Roof Replacement Cost in Illinois by Material
Asphalt shingles are the most common material for new roofs, with nearly 75% of homes in the nation using them as their material of choice. That said, homeowners also use various roofing materials, including metal, wood, clay, and slate.
In Illinois, the materials contractors select are heavily influenced by the state’s harsh climate conditions, including significant temperature fluctuations that can cause expansion and contraction. Asphalt shingles remain the most popular choice due to their cost-effectiveness and solid performance in Illinois weather. Note that you should consider upgrading to architectural or impact-resistant shingles for better durability.
Metal roofing is a popular choice in areas prone to severe weather, as it provides excellent protection against hail and can effectively handle heavy snow loads. Wood shingles and shakes, while visually pleasing, require frequent upkeep in Illinois due to the state’s humid summers to prevent rot. Clay and slate materials offer superior longevity, but are less common due to their weight requirements and higher installation costs. These high-end materials make sense, however, for historic renovations or high-end homes that seek maximum durability and a distinctive appearance.
The table below shows the total cost and average cost per square foot of roofing materials in Illinois. The total cost figures are based on the median square footage of a typical home in Illinois.
| Roofing Material | Cost Per Square Foot in Illinois | Average Total Cost |
|---|---|---|
| Asphalt | $4.70 | $5,081 |
| Metal | $8.77 | $9,467 |
| Wood | $11.16 | $12,057 |
| Clay | $15.33 | $16,559 |
| Slate | $15.41 | $16,643 |
Other Potential Roof Replacement Costs in Illinois
Beyond the basic material and labor costs, you may incur additional expenses during your roof installation, which can impact your total roofing project budget. Understanding these potential costs can help you avoid budget surprises and ensure you’re prepared for the complete scope of your roofing project.
Removing Existing Roofing
According to Homewyse, it typically takes about 1.5 labor hours to remove 100 square feet of roofing material, depending on your contractor’s hourly rate, speed, and roof size. In Illinois, disposal costs may be lower in urban areas with convenient disposal facilities. Rural areas, where longer hauls to approved disposal sites are typically required, often increase fees.
Inspections and Permitting
Illinois municipalities typically require permits for full roof replacements. Large metropolitan areas, such as Chicago and other major cities, may have additional inspection requirements. Cook County and other urban areas often have more stringent permitting processes that can add time and cost to your project.
Dry Rot
Sometimes, if your roof has not withstood wear and tear, your contractor will find signs of rot that you should plan to repair. The amount you pay for new wood and the removal of damaged material depends on the extent of the damage. Illinois’s humid summers and freeze-thaw cycles can be particularly damaging to roof decking, making rot issues more common in homes with poor ventilation or a history of previous leak problems.
New Roof Cost in Illinois Compared to Nearby States
Illinois roofing costs are generally competitive when compared to neighboring Midwest states. The Prairie State’s costs fall within the middle range among regional neighbors, with some states showing slightly higher or lower averages due to local economic conditions and weather-related demands.
For instance, Wisconsin’s marginally higher costs often reflect the state’s more severe winter conditions that require enhanced snow load capabilities and specialized installation techniques. Indiana also shows slightly higher costs compared to Illinois, despite similar climate conditions, likely due to regional labor market differences and material distribution networks.
Michigan’s costs are surprisingly close, and Iowa’s lower costs reflect the state’s more rural nature and generally lower labor rates. Missouri’s costs fall between Illinois and Iowa, consistent with regional economic patterns.
These comparisons aim to help you understand that your roofing investment provides good value while meeting the demanding requirements of Midwest weather conditions. The table below details the average cost per square foot for an asphalt roof replacement based on the state.
FAQs About Roof Replacement Costs in Illinois
What is the average lifespan of a roof in Illinois?
The lifespan of your roof depends on the material you choose and how well it handles the state’s weather conditions. Asphalt shingles typically last 20–25 years in Illinois, although this duration can vary depending on the quality of the materials. Architectural shingles often outperform basic three-tab shingles, lasting approximately 25–30 years due to their enhanced durability and wind resistance.
How much should a 2,200-square-foot roof cost in Illinois?
A 2,200-square-foot roof replacement would cost approximately $8,821–$9,866 in Illinois, based on our research. The final price you pay will depend on several important factors. Your home’s architectural complexity plays a major role. For example, a simple ranch-style home with a basic gable roof will cost significantly less than a multi-story colonial with dormers, valleys, and multiple roof planes.
Do I need to consider special roofing requirements for Illinois’s climate?
Yes, Illinois’s continental climate and severe weather patterns require specific roofing considerations to ensure optimal performance and longevity. The state’s significant temperature swings, from sub-zero winters to hot, humid summers, can cause materials to expand and contract repeatedly, leading to leaks and premature failure. To prevent future issues, we recommend investing in high-quality materials and reputable contractors who can properly install your new roof.
When is the best time to replace a roof in Illinois?
The best time for roof replacement in Illinois is typically late spring through early fall, with May through September offering the most favorable weather conditions. This timeframe avoids the harsh winter months when snow, ice, and freezing temperatures can make roofing work difficult.
How We Get Our Roofing Cost Data
The cost to replace a roof varies based on a few key factors: the home’s square footage, number of stories, roof pitch, type of roofing material, and pricing in your area.
For each home size, we used calculator.net to calculate a total roof area, using a 6/12 roof pitch with one-foot eave overhangs. The calculation includes a weighted average of one-story versus two-story homes across the United States.
We converted the roof area measurement into “squares” (the roofing industry’s standard unit, with one square covering 100 square feet) to align with how materials are sold and priced. Then we sourced material costs directly from RSMeans data from Gordian®, the industry’s leading construction pricing database used by professional contractors nationwide.
For state averages, we used clark.com to find the median home size in each state. While these figures provide an estimate for budgeting purposes, actual prices vary based on region, specific property characteristics, location, and current market conditions. For the most accurate pricing, we recommend requesting quotes from at least two reputable roofing companies in your area.
