Each city page names the registry its rows came from and links each business to its own record. A listing is not a recommendation. Where a city has no usable license file, the page lists top-rated businesses from a Google Maps search and shows the month those ratings were checked. A rating is not a license check. Local facts on city pages, such as housing age, wages, climate and hazard ratings, come from the datasets below. Cost figures, where this site publishes them, are copied from the cited pages with the date each one was checked. The "Updated" line on a city page or cost guide is the newest of those source dates. Dataset assembled November 2026. License registries used on this site: - Florida Department of Business and Professional Regulation (8,236 listings) - California Contractors State License Board (4,754 listings) - Illinois Department of Financial and Professional Regulation (3,619 listings) - Washington State Department of Labor & Industries (1,203 listings) - Virginia Department of Professional and Occupational Regulation, Board for Contractors (808 listings) - Oregon Construction Contractors Board (566 listings) - Connecticut Department of Consumer Protection (440 listings) - Nevada State Contractors Board (222 listings) - Minnesota Department of Labor and Industry (206 listings) Datasets behind the local facts: - [U.S. Bureau of Labor Statistics: Occupational Employment and Wage Statistics (OEWS), May 2025](https://www.bls.gov/oes/special-requests/oesm25ma.zip) - [U.S. Census Bureau: American Community Survey 5-Year Estimates, table-based Summary File (2024 table-based Summary File)](https://www2.census.gov/) - [OMB / U.S. Census Bureau: Core Based Statistical Area Delineation File (List 1) (July 2023)](https://www2.census.gov/) - [U.S. Census Bureau: 2026 TIGER/Line Gazetteer County Subdivision file (Connecticut only)](https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2026_Gazetteer/2026_gaz_cousubs_09.txt) - [U.S. Census Bureau: 2026 TIGER/Line Gazetteer Files (places, counties, ZCTAs, states)](https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2026_Gazetteer/) - [U.S. Census Bureau: 2020 Census Place by County reference file](https://www2.census.gov/geo/docs/reference/codes2020/place_by_cou/) - [U.S. Census Bureau: 2020 Census ZCTA-to-County Relationship File](https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_county20_natl.txt) - [U.S. EPA / DOE, ENERGY STAR: ENERGY STAR Version 7.0 Climate Zones by County/ZIP (Windows, Doors, and Skylights) (V7.0)](https://www.energystar.gov/sites/default/files/asset/document/ClimateZones_County.xls) - [Florida Building Commission: Florida Building Code 2023, Chapter 2 Definitions - High Velocity Hurricane Zone (FBC 2023)](https://up.codes/viewer/florida/fl-building-code-2023/chapter/2/definitions#high_velocity_hurricane_zone_) - [FEMA: National Risk Index for Natural Hazards - County-level table, v1.20 (v1.20, December 2025)](https://www.fema.gov/about/reports-and-data/openfema/nri/v120/NRI_Table_Counties.zip) - [NOAA National Centers for Environmental Information: U.S. Climate Normals 1991-2020 (annual/seasonal and monthly, by station)](https://www.ncei.noaa.gov/data/normals-annualseasonal/1991-2020/access/) - [Pacific Northwest National Laboratory (DOE Building America): Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270) (2021 IECC)](https://basc.pnnl.gov/sites/default/files/ClimateZoneDataFiles.zip) ## Optional - [Privacy](https://roofleakrepair.net/privacy/) - [Terms](https://roofleakrepair.net/terms/)
