How Much Does a New Roof Cost in Illinois? (2026 Guide)
Short answer: most homeowners in Northern Illinois spend roughly $8,000 to $25,000 on a new asphalt-shingle roof, with the typical suburban home landing around $12,000–$18,000. The spread is wide because the number depends on your roof's size, pitch, material, and how much old roofing has to come off. Here's how to figure out where your house falls before a single salesperson knocks.
What drives the price
Five things move a roofing quote more than anything else:
- Size (the biggest factor). Roofing is priced per "square" (100 sq ft). An average home is 20–30 squares.
- Pitch & complexity. Steep roofs and lots of valleys, dormers, or hips cost more labor.
- Tear-off. Removing one or two existing layers adds labor and disposal cost.
- Material/line. 3-tab is cheapest, architectural is standard, designer and metal cost more.
- Extras. New decking, ventilation, ice-and-water shield, and flashing add up.
Cost by shingle line (installed, per square)
| Line | Per square installed | Notes |
|---|---|---|
| 3-Tab | $90–$110 | Budget/rental look; mostly phased out |
| Architectural (standard) | $120–$160 | What ~80% of IL homes get today |
| Designer / luxury | $170–$250 | Mimics shake or slate; $5K–$10K more on an average roof |
| Metal | $250–$450+ | Long life, higher upfront |
On a typical 22-square roof, that's roughly $2,600–$2,400 (3-tab) up to $3,700–$5,500 (designer) just in shingle line — before tear-off and extras, which is why the all-in number lands in the ranges above.
The hail/insurance angle (Northern IL specific)
Our region sees enough hail that Class 4 impact-resistant shingles are worth a look. They add about $1,800–$2,400 on an average roof but can earn a 15–30% discount on the roof portion of your homeowner's insurance — often a 7-year payback before you even count the hail protection. Same color palette, no appearance tradeoff.
How to get an accurate number (and tighter bids)
Two moves: first, decide what you actually want — line and color — so you're comparing apples to apples across bids. Our free Roof Visualizer lets you see any color on your actual house in about 25 seconds, so you walk into bids with a specific product in mind. Second, get three local bids on the same spec. Contractors bid tighter when they know you've done your homework.
