Why roof replacement costs differ in Illinois

These figures start from the US national average for a roof replacement ($9,500 typical) and adjust for Illinois using a state construction-cost index of 105 (100 = national average). That index reflects local labor rates, material delivery, and permitting — the things that make the same project cost different amounts in different states.

The biggest swing factors for a roof replacement are roofing material, roof size, pitch and complexity, with labor running 50–60% of the total. Quoted rates typically run $4–$11 per sq ft. Always get at least three local quotes — a single contractor's bid can vary widely from the market rate.
