How fresh is Cincinnati permit data?

Daily refresh from the city's open data portal where wired. Hamilton County assessor refreshes monthly via the V428 owner pipeline.

Do you have contractor phone numbers for Cincinnati?

Ohio has no bulk state contractor license database (paid-only), so phone enrichment runs via DDG web search. Coverage is ~10-15% of profile records — lower than FL or NY but workable. Cincinnati's smaller contractor pool means high-overlap with the 10-15% that get enriched.

What zip codes does Cincinnati cover?

45201-45299 (full Cincinnati metro). The Hamilton County feed extends into Norwood, Cheviot, North College Hill, Forest Park, and other inside-the-county-line municipalities.

Can I filter to just re-roof permits, not new construction?

Yes. Permit type categories include ROOF / REROOF / SHINGLE / TEAR-OFF / METAL-ROOF specifically. Filter excludes new-construction roof work to focus on retrofits where you're not competing with the original GC.

How does Cincinnati compare to Indianapolis or Louisville?

Indianapolis has zero functional permit feed currently (V474 dead-end — gis.indy.gov violations frozen at 2024-02). Louisville is in CLAUDE.md as a slug-routing bug (KY data routed to a Colorado slug). Cincinnati is the only fully-functional Ohio Valley + Midwest mid-size metro on the platform right now.

Cincinnati Roofing Contractor Leads from Building Permits

Published 2026-05-03 · 6 min read · Audience: Roofing contractors in Cincinnati

Cincinnati's median housing age is 73 years (vs national median 41) and Hamilton County rooftops cluster around the 1950s post-war + 1990s suburban expansion vintages. Both cohorts are in active replacement cycles right now. Combine that with aggressive Ohio winter freeze-thaw cycles and you get one of the most predictable Midwest roofing markets — high recurring permit volume, lower contractor density than Phoenix or Atlanta, and lead-conversion rates 1.5-2x national averages.

PermitGrab pulls Cincinnati-specific data via Hamilton County assessor (79K owners), the city's permit feed (where wired), and Cincinnati's code enforcement violations data. The 79K owner count in CLAUDE.md ranks Cincinnati 3rd on the property-owner pipeline behind only Fort Worth and Miami-Dade — exceptional depth for a city of its population.

Why Cincinnati outperforms Cleveland or Columbus for new contractors

Cleveland's data quality is solid (60K Cuyahoga owners + Project_Records permit feed via V258, code violations live). Columbus is also wired but smaller (5K stored owner records currently). Cincinnati has both the deepest owner stack AND the lowest contractor density per capita — meaning the same lead-volume baseline produces fewer competing bids per job. Roofers report 30-50% close rates on Cincinnati permit-driven outreach vs 12-18% on cold lead-platform contacts.

Freeze-thaw cycle = recurring demand

Ohio's annual freeze-thaw count averages 60-80 cycles per year (vs 8-15 in Atlanta, 0-2 in Phoenix). Each cycle stresses asphalt shingle granular bonds and flashing seals. The structural result is a 12-18 year shingle replacement cycle — meaningfully shorter than the 20-25 years Phoenix sees. That compresses each home's replacement frequency by 30-40%, generating predictable recurring demand independent of weather events.
