What Moves The Price In Illinois

The honest factors.

Labor. Illinois roofers earn a median $37.45/hr (BLS OEWS, May 2025) against a national median of $26.65/hr. Our Illinois rates adjust the national dataset by that difference, applied to the labor share of the job.

Weather and code. Freeze-thaw cycles and Chicago union labor rates make Illinois one of the priciest states per square.

Licensing. Illinois requires a state roofing contractor license from IDFPR — verify it.

The invisible stuff. Decking replacement ($65–$95 per sheet, installed) and extra shingle layers are only fully countable after tear-off — which is why every number on this page is a range, and why our satellite estimate shows its imagery date.

Optional — Real Prices

Want real prices instead of a range?

Want real prices? We can send your roof details — size, pitch, and the estimate — to local roofers and let them send you their price. We never give them your phone number. You compare in peace, and if you like one, you decide who gets to contact you.

Coming soon to Illinois: the real-prices step launches area by area as local roofers are vetted. The free estimate above works everywhere, today.

What's in it for us? If you choose one of these roofers, they pay us a small referral fee. You never pay us anything, and it doesn't change the price they give you.

No thanks — I'll just use the free estimate. That's fine. It stays free either way.
