How long do garage doors last?
Nobody sets an official figure. We found no standards body or government lifespan for a garage door, only what the makers themselves say, and their numbers shift from page to page and year to year.
B&D's article on door life says fitters generally agree a garage door lasts somewhere between 10 and 30 years, depending on several factors. Steel-Line's roller door page says a roller door can last 15 to 20 years or more with proper maintenance. Its May 2025 article goes further: a good-quality roller door can last up to 30 years if it is looked after, though some parts may need replacing along the way.
What each maker says, and when
| The maker's figure | Where it comes from | |
|---|---|---|
| A garage door | Between 10 and 30 years, the range B&D says fitters generally agree on | B&D's article on how long its doors last (no date shown) |
| A roller door | 15 to 20 years or more, with proper maintenance | Steel-Line's roller door page, read November 2026 |
| A roller door | Up to 30 years, with proper maintenance | Steel-Line article, May 2025 |
| A B&D Roll-A-Door | Over 15 years at five opens and closes a day, from testing at 20,000 to 30,000 cycles | B&D's roller door page |
| An opener | Typically 10 to 15 years | Steel-Line article, May 2025 |
| Garage door rollers | Replace every 10 to 20 years, depending on use | Steel-Line maintenance guide, 2021 |
| Garage door rollers | 7 to 15 years, depending on the material | Steel-Line article, May 2025 |
| Springs | 7 to 12 years on average in Australian conditions | Steel-Line springs article, February 2026 |
| Torsion springs | 10,000 cycles, about 7 to 10 years for most homes at 3 to 4 uses a day | B&D springs article (no date shown) |
| Opener backup battery | 3 to 5 years for Merlin's E475M; 4 to 5 years for ATA's next generation kit | Each maker's battery backup manual |
| Brush seals | Replaced every three to five years for most homes | B&D brush seal article |
| Gate openers | Designed for over 150,000 cycles | Merlin's gate opener page |
Why Steel-Line's numbers don't agree
Read two Steel-Line pages a few years apart and you get two answers. Its 2021 maintenance guide said rollers need replacing every 10 to 20 years depending on use, and its May 2025 article says they last 7 to 15 years depending on the material. For the roller door as a whole, its product page says 15 to 20 years or more, while the 2025 article says up to 30.
Each is Steel-Line's figure from that page in that year. None is a promise for your door, and putting them together does not make a typical figure.
Garage door life is counted in cycles
A cycle is one opening and closing. B&D says its minimum test for a new door design is 30,000 cycles, which it equates to 30 years at an average of 1,000 cycles a year, and that some of its models have passed 60,000 cycles in testing.
Your own habits change that sum. Steel-Line says the average family uses its garage door 3 to 5 times a day, nearly 2000 times a year, which is double the yearly figure in B&D's sum. A door that is the main way in and out of the house reaches its count much sooner than one opened on weekends.
Warranties are written in cycles too. B&D's warranty table pairs each door's years with a cycle limit, whichever comes first: Roll-A-Door 5 years or 30,000 cycles, Panelift 3 years or 10,000 cycles, Rollmasta 3 years or 15,000 cycles. Its Power Drive opener carries a 7 year or 20,000 cycle warranty, which B&D says works out at roughly seven to eight cycles a day. A warranty is not a lifespan, but it shows the makers think in uses as much as in years.
How long do garage door springs last?
Springs wear by use more than by age. Steel-Line's February 2026 article says most springs in Australian conditions last 7 to 12 years on average, and that standard residential springs are typically rated for 10,000 to 20,000 cycles. B&D's springs article puts torsion springs at 10,000 to 20,000 cycles depending on grade, and high-cycle springs at 20,000 to 30,000.
B&D's warranty page rates the springs at 15,000 cycles on Rollmasta and Firm-A-Door, and 20,000 on Flex-A-Door, StormShield and Designer Door. Its Smart Pro manual adds that springs naturally lose tension over time, so a door that slowly gets heavier can be a spring wearing out.
Never replace a spring yourself. The broken spring guide and spring and cable repairs explain what a door specialist does.
How long do garage door openers and motors last?
Steel-Line's May 2025 article says openers typically last 10 to 15 years. That is the only opener life figure from a maker in Australia that we could confirm. Other makers publish cover rather than a forecast: Merlin gives 3 to 7 years of warranty on its openers depending on the motor, and B&D says all its motors carry a warranty of between five and seven years.
Some parts give out sooner. Merlin's E475M manual says its backup battery lasts 3 to 5 years under normal use, and ATA's next generation Battery Backup Kit manual says its batteries should not need replacing for 4 to 5 years. Remotes can run out of matches, too: Gliderol says its newer G+ rolling code remotes may not suit a motor more than 15 to 20 years old.
An older opener can also be short on safety features. Steel-Line calls an opener's reversing feature only a precaution and strongly recommends adding a photo eye, and B&D says a Standards Australia change from 1 December 2020 made safety beams compulsory with the sale of any smart opener device. Replacing a garage door motor covers the swap.
Rollers, seals and cables
Rollers are the part most likely to be replaced along the way. Steel-Line says a standard five-section door has a dozen rollers and they should all be done at once, and that nylon rollers need less maintenance than metal ones.
B&D says most bottom weather seals last several years, depending on climate and use, and suggests checking them once a year for cracks, gaps or hardening. It says most brush seals need replacing every three to five years, depending on weather and use.
For lift cables, B&D gives seals, springs and lifting cables a 1 year warranty and treats them as normal wear and tear that a regular service replaces.
What shortens a garage door's life
- Salt and industry nearby: B&D's warranty brochure says prolonged exposure to marine, industrial or other corrosive environments affects a door's life expectancy, including any install within 1 km. The rust guide has each maker's coastal limit
- Heavy use: more cycles a day means the springs and opener reach their ratings sooner
- Skipped services: ATA's GDO-6 manual says failing to maintain the garage door voids the opener warranty, and Steel-Line's longer figures assume proper maintenance
- A door out of balance: Steel-Line says a roller door that is out of balance strains the motor
- No rain washing: B&D names doors under an eave, carport or verandah reaching more than 600mm from the wall
Signs a door may be near the end
- Rust has eaten through the curtain or a panel, not just marked the surface
- The same fault keeps coming back after each repair
- A damaged section that is no longer made
- The opener has no safety beams and new remotes won't pair with it
- It stays heavy to run by hand even after a service
Replace the door, or keep it going?
A door's condition matters more than its birthday. A sound door with a tired spring, worn rollers or an old seal is a repair, and a service shows which parts are due. When the curtain or panels themselves are failing, garage door replacement sets out what changes and what can stay.
Worn springs and cables stay with the door specialist
A spring near the end of its cycles still holds the force that balances the whole door. Steel-Line warns never to loosen any fastener on a sectional door's spring assembly or bottom cable fixtures, and never to try to tension a roller door, at risk of serious injury or death. B&D says spring replacement is not a DIY task.
What you can do, and what to leave
You can
- Count roughly how often the door runs each day
- Find the install date and the door and opener models
- Keep service records with the warranty papers
- Check the seals once a year
Leave to a door specialist
- Springs and cables at the end of their life
- Rollers, tracks and hinges
- Opener drive, backup battery and safety beams
- Telling a tired door from one past saving
What we would do
Before you replace a door because of its age, book a service and ask for a written list of what is worn. A door that balances, runs smoothly and has sound panels can carry on with new springs, rollers or seals, and that list gives you something real to weigh against a new door.
