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
Missouri homes get humid summers, winter freeze-thaw, and severe spring storms — moisture and impact damage are the twin local patterns. Across the 1 Missouri cities we track, an average of 38.2% of homes were built before 1980 (U.S. Census Bureau, ACS 2020–2024) with average annual rainfall of 38.3 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.
