City-by-city 2026 guides with real local housing and rainfall data — know the warning signs and how inspections work before you hire.
Last updated: October 2026
Kentucky's humid climate with freeze-thaw shoulder seasons means moisture management — flashing, caulk, and ventilation — decides how long siding lasts. Across the 7 Kentucky cities we track, an average of 53.0% of homes were built before 1980 (U.S. Census Bureau, ACS 2020–2024) with average annual rainfall of 44.5 in/yr (NOAA 1991–2020 normals).
Each city page pairs siding how-it-works guidance — warning signs, the inspection process, materials, repair vs. replace — with that city's real housing-age and rainfall data, so you can see which pattern dominates locally. When you talk to contractors, ask how their plan accounts for the local weather, and whether they probed for rot before quoting a scope.
