Siding lifespan (years) by material

Typical published planning values — NOT a certified spec or professional advice. Coverage and exposure vary by product and installation; confirm on the manufacturer’s installation instructions and stated coverage. Moisture, flashing, sheathing and pre-1978 lead paint on old siding are a pro’s call — follow the manufacturer’s instructions, local code and the EPA RRP rule and hire a certified firm; lead-paint abatement, structural and moisture repairs and code certification are not engineered here.

Lifespan depends on climate, install quality and upkeep — wood needs the most maintenance to hit its range. These are LABELED planning typicals, not a warranty; confirm the manufacturer’s data. Use them with the lifespan & maintenance reference and the material selector.
