What roofing costs across Illinois

Across the 52 Illinois cities covered here, architectural shingle replacement on a 2,000–2,500 sq ft home spans $11,000–$24,900, with a state midpoint of $17,200.

Unusually, pricing barely moves across the state: only 7% separates the lowest market (Addison) from the highest (Chicago). In Illinois, roof complexity and deck condition will move your number far more than location does.

Illinois’s climate is not uniform either. Annual snowfall runs from 12 in around Belleville to 44 in around Waukegan, which changes whether ice-barrier depth at the eave is the detail that decides service life or a line item that barely matters.

Roofing work is generally administered under state-adopted residential code frameworks with municipal permit and inspection enforcement. Across the 52 Illinois cities where we have fee data, permit and inspection costs cluster near $415.
