Sample insight
Tear-off and full asphalt-shingle replacement on a typical IL single-family home runs $6.50–$11.50 per square foot installed in 2026, with Chicago bungalow flat-roof replacements (modified bitumen / EPDM) commonly $11–$20 per square foot installed once parapet, scupper, and code-compliant insulation are accounted for. Metal roofs run 1.8–2.8x the shingle baseline. (Estimate based on 2024–2025 Illinois permit and bid data.)

Frequently asked
What homeowners ask before downloading.
Does the report cover Chicago bungalow flat roofs?
Yes. Chicago flat-roof replacement with modified bitumen or EPDM has its own section — parapet rebuild, scupper detailing, and code-compliant insulation that pitched-roof contractors often miss.
How does the report handle insurance claims?
We cover when a wind or hail claim is realistic versus a sales pitch, and how to read a contractor's claim-handling involvement without losing leverage on scope.
Will I get added to a contractor lead list?
No. Your email is used to deliver the report and occasional research updates. We never sell, share, or auction your information to roofers or third parties. Unsubscribe anytime.
