Is your Illinois roof nearing its “sell-by date,” or should you honestly have replaced it a few years ago? Although you look forward to a brand-new, beautiful, and potentially more energy-efficient roof over your head (who wouldn’t?), you have the feeling that the cost of that much-needed roof replacement in IL will be a bitter pill to swallow.
How much does roof replacement cost in Illinois in 2025?
The national average cost of a roof replacement is $11,500 — and most homeowners spend anywhere between $6,700 and $80,000.
If that ballpark idea seems a little too broad to be useful, that’s because nearly everything about your choices can impact the cost of a new roof.
1. The Materials You Choose
Asphalt shingles, which adorn 75 percent of all American homes, are the most affordable choice. They usually cost between $4.50 and $8 per square foot. That’s the national average, and Illinois neatly falls into it. Although the cost of a roof replacement goes up in major metro areas, typical costs in Chicago are quite reasonable, at an estimated $6 to $8 per square foot.
If you choose solar shingles for your roof, on the other hand, you can expect to pay closer to $35 per square foot. Are you interested in metal roofing, natural slate, concrete roof tiles, or luxury asphalt shingles? The cost of your roofing materials will fall somewhere between these extremes.
Table 1: Roof Replacement Cost by Material
| Material Type | Cost Per Square Foot | Estimated Total Cost for 1,500 sq. ft. |
| Asphalt Shingles | $4.50 – $8.00 | $6,750 – $12,000 |
| Solar Shingles | $35.00+ | $52,500+ |
| Metal Roofing | $9.00 – $15.00 | $13,500 – $22,500 |
| Natural Slate | $15.00 – $30.00 | $22,500 – $45,000 |
| Concrete Roof Tiles | $10.00 – $20.00 | $15,000 – $30,000 |
| Luxury Asphalt Shingles | $8.00 – $12.00 | $12,000 – $18,000 |
2. The Size of Your Roof
It goes without saying that your new roof’s cost depends on its size. The larger your Illinois roof is, the more material your roofers need to finish the job — and the longer it will take. (Don’t worry! That doesn’t mean your roof replacement will take weeks. Experienced roofers work efficiently and quickly in the right weather conditions, but a small roof installation still goes faster than a very large one.)
Table 2: Roof Replacement Cost by Size
| Roof Size (Square Feet) | Cost Range for Asphalt Shingles | Cost Range for Metal Roofing | Cost Range for Solar Shingles |
| 1,000 | $4,500 – $8,000 | $9,000 – $15,000 | $35,000+ |
| 1,500 | $6,750 – $12,000 | $13,500 – $22,500 | $52,500+ |
| 2,000 | $9,000 – $16,000 | $18,000 – $30,000 | $70,000+ |
| 2,500 | $11,250 – $20,000 | $22,500 – $37,500 | $87,500+ |
3. The Pitch
Steeper roofs are more complex to install, and because they have more square footage compared to low-pitched roofs, more materials are needed. What’s more, your roofing team also incurs bigger risks when replacing steep roofs. So it’s understandable that your roof’s pitch influences your total replace roof cost, isn’t it?
Table 3: Factors Impacting Roof Replacement Cost
| Factor | Cost Impact |
| Materials | Higher-end materials significantly increase the total cost. |
| Roof Size | Larger roofs require more materials and labor. |
| Roof Pitch | Steeper roofs increase costs due to additional labor and material requirements. |
| Roof Condition | Repairs to the deck or insulation add to the total cost. |
| Contractor Choice | Experienced contractors may charge more but offer higher quality results. |
4. The Roofing Company You Choose
Over 1,000 different roofing companies replace and repair roofs in Illinois — but it may come as a surprise to learn that just over 12 percent of roofers have been in the business for more than a decade.
Illinois homeowners shopping around for the best roofing company may request estimates from a few and find themselves tempted to go with the most affordable roof estimate. Watch out, though, because cheaper isn’t always better!
Ask any roofing company about their experience and professional affiliations before you make your choice, and don’t be scared to ask for references from previous customers, either. After all, roofing is among the most skilled jobs in the construction industry and beyond, and the quality of your roof replacement sets the stage for your roof’s performance.
5. Your Roof’s Condition
Some homeowners think of their roof as nothing more than roofing materials they can see — but there’s a lot going on under the surface, too. If your roof deck is in excellent condition, it won’t need extensive repairs to get it ready for a roof replacement, lowering your total costs. On the other hand, if you’re looking to make major upgrades or have more efficient insulation installed, the price tag goes up.
How Do I Estimate the Cost of a New Roof in 2025?
So to recap, understanding what goes into your roof replacement estimate can give you more control over the final cost. Factors like materials, roof size, pitch, and the condition of your existing roof all contribute to the total cost.
