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
New York spans two siding climates: lake-effect snow and freeze-thaw upstate, coastal storms and humidity downstate — over some of the oldest housing stock in the country. Across the 75 New York cities we track, an average of 79.6% of homes were built before 1980 (U.S. Census Bureau, ACS 2020–2024) with average annual rainfall of 42.3 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.
