A roof's lifespan depends heavily on the material it's made of. Here's the general range by roofing type:
| Roof material | Life expectancy |
|---|---|
| Asphalt shingles | 15–25 years |
| Clay tile | 30+ years |
| Concrete tile | 50 years |
| Wood shake / shingles | 15–35 years |
| Slate tile | 35–100 years |
| Tar and gravel (built-up) | 10–30 years |
| Other materials | 5–25 years |
A widely-cited Florida Realtor Magazine infographic on home component life expectancy focuses narrowly on asphalt shingles, putting that material's typical life at around 20 years — within the broader 15–25 year range above.
Sourced from the National Association of Home Builders / Bank of America equity study on life expectancy of home components:
| Component | Life expectancy |
|---|---|
| Air conditioning unit | 10–15 years |
| Carpeting | 8–10 years |
| Deck (wood) | 10–15 years |
| Driveway | 10–20 years |
| Exterior paint | Up to 15 years |
| Flooring (wood or stone) | 100 years |
| Furnace | 10–18 years |
| Garage door opener | 10–15 years |
| Garbage disposal | 12 years |
| Heat pump | 16 years |
| Kitchen cabinets | 50 years |
| Kitchen faucets | 15 years |
| Roof (asphalt shingles) | 20 years |
| Windows | 10–30 years |
If a seller hasn't already factored in the age of a home's components, a buyer may come back and try to renegotiate price once an inspection turns up components nearing (or past) their typical replacement window. An appraisal can also come back lower than expected for the same reason. The ranges above cover a wide variety of components — not every one will apply to every house, but knowing where your roof, AC, and other major systems sit in their expected lifespan helps you set realistic price expectations before a buyer's inspector finds it for you.
