How long do gutters last?
How long gutters last
| Type | Published service life | Roots plans for |
|---|---|---|
| Aluminum | 20–40+ years (sources differ) | Year 20 |
| Galvanized steel | 20 years | Year 20 |
| Copper | 50+ years | Year 50 |
Service life is a planning horizon, not an expiry date. It tells you when to start budgeting, get a second quote, and stop paying for repairs on something near the end — not the day it stops working.
What changes this
Copper. Both sources state 50+ rather than a range, so treat this as a floor. Copper gutters usually outlast the owner, and the seams and hangers give out before the metal does.
Why published figures disagree
Aluminum. The ranges overlap but the midpoints are 40% apart — InterNACHI prints 20–40+, NAHB a flat 20. Planned at 20: it is the only figure both sources actually support, and the midpoint rule would otherwise hand back 30 years on the strength of one source's upper bound.

Service-life figures are typical estimates drawn from published industry references. Where a second reference covers the component, the figure is cross-checked against it and any disagreement is set out above; where only one reference covers it, that is stated. Actual life varies with installation, water quality, climate, and maintenance, and these figures shouldn't be relied on for insurance, lending, or warranty decisions.
Maintenance is what decides where in the range you land
The published range is wide for a reason: two identical units, installed the same day, routinely fail years apart. What separates them is upkeep.
For gutters, the tasks that matter most:
- Clean gutters and downspouts — Overflowing gutters rot fascia, dump water at the foundation, and cause winter ice dams.
Roots tracks the age of every component in your home alongside the upkeep that extends it, so the replacement is a planned expense instead of an emergency.
Frequently asked questions
- How long do gutters last?
- It depends on the material: Roots plans a replacement between year 20 and year 50, depending on which of 3 types you have.
- When should you replace gutters?
- Roots plans between year 20 and year 50, depending on the material. Measure from installation, and treat it as a budgeting horizon rather than an expiry date.
