Door types and construction
What is a roller garage door?
A roller garage door is made of interlocking aluminium slats that coil into a compact barrel above the opening as it opens, leaving the ceiling and walls clear inside the garage. In the UK an electric insulated aluminium roller typically installs for around £1,895, with a realistic range of £1,700–£2,800.
Why rollers suit small garages
Because the slats coil into a barrel fitted at the top of the opening rather than running back on tracks, a roller door needs very little space inside the garage — no side tracks eating into wall space and no panels overhead once open. This makes it a common choice where the garage doubles as a workshop or storage space and every centimetre of usable width matters.
Insulation and operation
Roller slats are usually foam-filled aluminium for thermal performance, and the vast majority of UK roller garage doors are supplied electric as standard rather than manual, given the size and weight of the barrel assembly.
Questions people ask
- Are roller garage doors noisy?
- A well-installed and regularly serviced roller door should run smoothly with a low hum from the operator; grinding or rattling usually points to worn rollers or a misaligned track, a repair typically costing £90–£200.
- Do roller garage doors reduce garage headroom?
- A roller door needs clearance above the opening for the barrel, typically around 250–300mm, which can slightly reduce usable ceiling height compared with a sectional door — an installer will confirm exact clearance for your opening.
- Is a roller garage door secure?
- Interlocking aluminium slats give a roller door a continuous locking surface with no visible hinge points, but overall security still depends on the specific lock and product certification rather than the door type alone.
