Asphalt shingle roof replacement by roof size: Chicago vs Decatur
Roofing is priced per 'square' (100 sq ft of roof). A roof is bigger than the home's footprint because of pitch and overhangs — a 2,000 sq ft home often has a 2,200–2,600 sq ft roof. Asphalt runs about $3–$5 per sq ft installed.
| Size | Chicago | Decatur |
|---|---|---|
| 1,000 sq ft (10 squares) | $4,850–$8,650 | $3,950–$7,050 |
| 1,500 sq ft (15 squares) | $6,250–$11,600 | $5,100–$9,450 |
| 2,000 sq ft (20 squares) | $7,100–$14,600 | $5,750–$11,850 |
| 2,500 sq ft (25 squares) | $9,250–$17,000 | $7,500–$13,800 |
| 3,000 sq ft (30 squares) | $11,050–$20,550 | $8,950–$16,700 |
| 3,500+ sq ft (35 squares) | $12,800–$24,150 | $10,400–$19,600 |

Cheapest time for asphalt shingle roof replacement in either city
Storm season pushes demand — and prices — up through summer, since shingles need warm, dry weather to bond correctly. Roofers with open winter calendars will often deal to fill a spring slot.
Where does a smart roofing budget go in 2026?
Two roofs of the same square footage can price hundreds apart because of something you can't see from the ground — the deck under the old shingles. Add the tear-off-versus-overlay call and the shingle grade, and you have the decisions that actually move the number.
The do-it-right case
Pay for a full tear-off and quality underlayment, flashing and ventilation. An overlay saves money today but traps heat, voids some warranties and costs more at the next replacement.
The value case
Architectural shingles sit between bargain 3-tab and premium metal or tile, and for most houses that middle ground is exactly right. They carry longer wind and wear ratings than 3-tab for a small step up in price, without the four-figure jump metal or tile demands.
The risk case
The surprise that wrecks a roofing budget is rot in the decking, and you rarely see it until the old shingles come off. Fix the price per replacement sheet in the contract before the crew starts, so a low bid can't quietly climb once the deck is open.
Three habits keep a roof from costing more than it should: strip to the deck, choose an architectural shingle, and get the decking-repair rate on paper before the tear-off begins. Storm season tends to produce the lowest bids and the shortest-lived roofs.
