How Long Things Last: A Home Maintenance Lifespan Guide
Roughly how long the major parts of a home and its appliances tend to last — so you can plan, budget, and avoid surprises.
Plan ahead, spend smarter
Knowing when big-ticket items typically need replacing helps you budget, prioritize repairs, and avoid being caught off guard — whether you’re maintaining your home, buying one, or getting ready to sell. The ranges below are typical estimates; actual life depends a lot on quality, climate, use, and how well things are maintained. Bay Area coastal weather, for example, can be tough on roofs and exterior paint.

A few ways to make things last longer
- Service your HVAC and change filters regularly — it’s the cheapest way to add years.
- Flush your water heater annually to fight mineral buildup.
- Keep gutters clear and exterior surfaces sealed and painted — water is a home’s biggest enemy.
- Address small repairs early, before they become big ones.
Please note: These are general estimates for planning, not guarantees — actual lifespans vary with quality, climate, use, and maintenance. For detailed component estimates, see InterNACHI’s life-expectancy chart.
