Homeowners usually ask us how long "the door" will last, but a garage door is really a system of parts that wear out at different rates - and Colorado's altitude UV, hail, and freeze-thaw cycling push most of them toward the short end of their ranges. Here's what to realistically expect, part by part.
The door itself: 15-30 years
A quality steel door lasts 15-30 years depending on climate, use, and maintenance. Insulated steel doors from brands like DoorLink, Ankmar, and Amarr sit at the top of that range; builder-grade uninsulated doors at the bottom. Along the Front Range, hail resistance is worth paying for.
Springs: 7-10 years, less in Colorado
Springs are rated in cycles, not years - typically 10,000 cycles, which works out to 7-10 years at 3-4 uses a day. Colorado's big daily temperature swings fatigue the steel faster, so high-cycle springs (25,000+) are the best upgrade-per-dollar on any door here.
The opener: 10-15 years
Openers usually give 10-15 years of service. If yours predates 1993 it lacks legally required safety sensors and should be replaced regardless of whether it still runs.
Rollers, cables, and hardware: 5-10 years
Nylon rollers last 5-7 years, cables and pulleys closer to 8-10. These are inexpensive parts whose failure causes expensive damage - which is why they're checked at every tune-up.
How to stretch every lifespan
- Lubricate springs, rollers, and hinges twice a year - fall lubrication matters most here
- Test door balance annually - an unbalanced door wears everything faster
- Fix small issues (noise, jerky travel) before they cascade
- Book a professional multi-point inspection before winter
