Why a roller door suits so many Geelong garages
A roller door winds up into a roll directly above the opening, so the ceiling inside stays clear for storage, a low beam or a shed's open roof frame. That makes it a common pick for carports and sheds as well as garages.
Size has limits, though. B&D's Series 1 Roll-A-Doors are made up to 3150mm wide, curtain overlap included, and up to 3000mm high depending on the model. Wider shed openings move into bigger ranges, such as Steel-Line's "B" light industrial series at 2855mm to 5500mm wide.
Headroom above the opening, by maker
| B&D (September 2026 guide) | Steel-Line (2026 brochure) | |
|---|---|---|
| Smaller residential doors | 430mm to 470mm (Series 1) | 430mm to 510mm ("A" and "AA" series) |
| Larger doors | 515mm to 620mm (Series 2 and 3) | Up to 570mm ("B" series) |
| How firm the figure is | Depends on the model and door height | A guide only |
Motors for roller doors
Roller door motors usually sit beside the roll, but not always. Gliderol's Rollamatic GEN II fits inside the roll and suits residential roller doors up to 12 square metres, while its Glidermatic Heavy Duty needs 120mm of side room. Steel-Line's roller opener has F-linX Wi-Fi and handles single or double doors up to 16 square metres.
In Victoria, a new power point for the motor is electrical installation work for a Registered Electrical Contractor, whose licensed electrician leaves you a Certificate of Electrical Safety.
Roller doors on bushfire prone land
The City of Greater Geelong says building in a designated bushfire prone area needs a BAL report, and even BAL-Low land must be built to BAL-12.5. For a garage door, the level sets the seals and gaps it needs.
Sources disagree on the level at which roller doors need brush seals and tight guide tracks, so the BAL report and the building surveyor make that call for each home. B&D adds that its BAL-40 tested BAL-Maze system is only for its sectional doors, not roller doors.
Spring tension is never a home job
The springs inside the drum are wound tight to balance the curtain. Never loosen the U-bolts or try to re-tension the door: Steel-Line warns it can bring the door down with force and cause serious injury or death.

The Bellarine and the bay
Gliderol's 7 year curtain corrosion warranty does not stretch to homes within 800 metres of high salt, so ask about cover if you live near the water in Portarlington, St Leonards or Clifton Springs.
Surf Coast towns
Torquay, Jan Juc and Anglesea were in the path of the 1983 Ash Wednesday fire. Out that way, find out the home's BAL before you pick a roller door.
Victoria's rules
No licence exists for garage doors in Victoria, and BPC registration only comes in once a job is worth more than $10,000.
What we would do
Measure from the top of the opening to the ceiling or the lowest beam before you ask for quotes. Between B&D and Steel-Line the headroom they ask for runs from 430mm to past 600mm depending on the door's size, and a tight space narrows the choice quickly.
