Roofing permit leads in Illinois: finding re-roof jobs from public permits
Updated October 25, 2026.
Most Illinois towns require a permit before a roof is torn off and replaced. That makes the permit list one of the few public records that shows, street by street, where roofs are being done right now.
What a roofing permit tells you
- Where the work is. Roofs on one street are often the same age, so one re-roof tends to be followed by the neighbours.
- Who is doing it. Many permits name the contractor, which shows who is busy in a town.
- What comes next. A new roof often brings gutters, siding, skylights or solar within a season or two.
- Storm patterns. A sudden run of roofing permits in one part of town often follows hail or wind damage.
Where Illinois towns publish permits
Each city and village runs its own permit office. Some publish permits through an online system the day they are issued; others release monthly reports, or keep permits on paper. Unincorporated land is handled by the county. That patchwork is why a roofer working several towns rarely has one list to watch.
How we sort permits into roofing
Permit descriptions are written by hand and vary from town to town. We sort each permit into trades from its description, and we offer roofing for a town only after checking that our sorting of that town's permits is accurate. Where it isn't yet, the permits still count in our totals, but we don't sell them as roofing leads.
What we hold today
