Choosing Roller Doors for Your Shed

10 October 2026

Start with what needs to fit through

The most common mistake is choosing a door size before measuring the things that will pass through it. Write down the height and width of your largest vehicle, including roof racks, aerials, mirrors and anything mounted on top. If you own or plan to buy a caravan, boat, motorhome, tractor or truck, measure that too. Then allow a sensible margin on each side and above, because reversing a trailer through an opening with only a few centimetres to spare is slow and stressful.

It also helps to think ahead. Many people build for the car they own today and later buy a taller four-wheel drive or a caravan. Raising a door opening after the shed is built usually means structural changes, so it is far cheaper to allow extra height at the design stage.

Door height and wall height go together

A roller door needs space above the opening for the drum the curtain rolls onto. That means the wall height of the shed has to be greater than the door height. If you want a tall door for a caravan or machinery, the shed walls need to be taller as well, which affects the overall look, cost and in some cases the approval pathway. Your builder can work through the relationship between wall height, door height and roof pitch for your site.

Roller doors vs sectional doors

Roller doors are the standard choice for most residential and rural sheds. They are simple, reliable, relatively affordable and available in a wide range of sizes and Colorbond colours. The curtain rolls up into a drum above the opening, so the ceiling space inside stays clear.

Sectional doors are made of horizontal panels that travel up on tracks and sit under the roof when open. They tend to seal better, can be insulated, and suit garages attached to or near the house where a more finished look matters. They need clear space under the roof for the tracks, which can clash with lighting, hoists or storage racks. For very large openings on commercial and industrial buildings, heavier industrial roller doors or other door systems are often used instead.

How many doors, and where

Door placement shapes the whole internal layout. A few practical points to consider:

• One door per bay is easiest for vehicles, because each car or machine can come and go without moving another.
• Doors on the gable end give a long, deep bay that suits caravans, boats and machinery.
• Doors at both ends of a bay create a drive-through, which is very handy for trailers and tractors on acreage.
• A personal access door lets you walk in without opening a roller door, which is better for security and keeps dust and heat out.
• Think about where the driveway, turning space and slope of the land are before locking in door positions.

If you are also planning a workshop area, keep it away from the main vehicle doors where possible, so benches and tools are not in the way of daily movements. Our guide to workshop shed design covers this in more detail.

Wind ratings in Queensland

Large door openings are a weak point in strong wind. When a door fails, wind can enter the building and put significant pressure on the roof and walls. In Australia, sheds are designed to a wind classification based on the site, and doors should be suitable for the same conditions. Wind-rated or wind-locked doors are often specified in exposed areas. The requirement depends on your location and site exposure, so check this with your builder and engineer rather than assuming a standard door is fine.

Manual or motorised

Smaller roller doors are easy to lift by hand. Larger and taller doors are heavier, and a motor makes daily use far more convenient, especially if you are in and out several times a day. Motors can usually be added later, but it is worth planning for power to each door at the build stage so you are not running cables across the walls afterwards. Remote controls, keypads and battery backup are common options.

Colour and appearance

Roller doors come in Colorbond colours, so they can match the walls or contrast with them. On a residential block, doors are usually the most visible part of the shed from the street or the house, so their colour has a big effect on how the building looks. Matching the doors to the trim or the house often gives a cleaner result than a strong contrast.
