What’s different about Chicago
Chicago's strict permitting, unionized labor, and high cost of living make it Illinois's priciest market, with harsh freeze-thaw winters adding durability demands.
- Snow load and ice dams call for ice-and-water shield and sturdier decking, pushing roof cost up.
- Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.
How the cost is built
Roof cost scales with roof area (measured in 100 sq ft 'squares'), pitch, and material — asphalt shingles are the budget choice, while metal, tile, and slate run two to four times more. Steep or complex rooflines, multiple layers to tear off, and new decking or flashing all add to the total.
