Roller, Sectional or Tilt Garage Door? A Sunshine Coast Technician Compares Them

Question 01

What's the difference between a roller, sectional and tilt garage door?

It's how they open. A roller door is one steel curtain that rolls around a drum above the opening. A sectional door is a row of hinged panels that runs up curved tracks and lies under the ceiling. A tilt door is one big panel that pivots out and up on arms and springs.

Steel-Line describes a roller door as sliding up its tracks and rolling around a barrel or drum. A sectional door bends at its hinges and slides back along a track until it sits under the ceiling. Door Systems Australia explains that on a tilt door with jamb hinges, up to half the door can stick out past the opening when it's up.

For styles and colours, see garage door types. What follows is what each door is like to live with day to day.

Question 02

How much headroom and side room does each garage door need?

A roller door needs the most height right above the opening, because the rolled-up curtain sits there. B&D puts it at around 450mm. A sectional door needs less there, around 350mm, but it also needs a clear run along the ceiling. A tilt door needs very little headroom but plenty of driveway.

• Headroom is the gap from the top of the opening up to the ceiling, or to the lowest thing in the way, like a beam or a pipe.
• Side room is the wall space beside the opening, where the guides or tracks and their brackets fix on.
• Backroom is the depth of the garage behind the door. A sectional or tilt door needs it clear to lie flat when it's open.
• Driveway room is the clear space out the front. Only a tilt door needs it, because it swings out.

The exact figures change with the maker, the model and the door size. Steel-Line asks for at least 430mm of headroom for its roller doors. B&D's instructions for its Panelift sectional door ask for 120mm of side room for a standard fit. With less room than that between the opening and a wall, it needs a special low side room setup. The opener matters too. B&D says a roller door's opener sits to the side of the door, while a sectional door's opener hangs from the ceiling behind it.

Tilt doors are the odd one out. Steel-Line says a tilt door can work with less than 200mm of head height at the opening, which it notes is common in some older homes such as the Queenslander. But the door still needs somewhere to go. Steel-Line says a tilt door won't suit a garage with a low ceiling and no room to store the open door.

Question 03

Which is better, a roller or a sectional garage door?

Neither wins everywhere. A roller door suits a garage with good height over the opening and a busy or sloping ceiling, and it's usually the cheaper door. A sectional door suits a flat, clear ceiling. It takes insulated panels and comes in more styles. If a panel gets damaged, it's often easier to fix.

A roller door might suit you if:

• Your garage ceiling has beams, a slope or storage up high. B&D says that's when a roller door is most likely the best fit.
• There's good height right above the opening.
• You want the ceiling left clear for storage.
• You'd like the lower-cost option. Steel-Line calls roller doors the most cost-effective choice compared with a sectional door.

A sectional door might suit you if:

• The ceiling is flat and clear, with room for the tracks to run back.
• There's room beside the opening for the tracks and brackets.
• You want insulated panels, windows or a particular look. Steel-Line says sectional doors are highly customisable.
• The garage is part of the house and you'd like it quieter. Steel-Line says insulated sectional doors can reduce noise from outside.

Damage is the other big difference. Steel-Line says a roller door that's hit by a car will need the whole door replaced, while a sectional door can be easier to repair if one panel is damaged. Dented garage doors covers what's fixable and what isn't.

Springs differ too. On a roller door they're hidden inside the barrel, and Steel-Line says they're less likely to snap. A sectional door carries its weight on torsion springs, cables and drums above the opening. Steel-Line notes it has more moving parts than a roller door, which can mean more upkeep over the years.

Question 04

Are tilt garage doors still a good choice?

They still suit some homes. A tilt door can fit an opening with very little headroom, and it can be made from timber, aluminium or steel. The catch is the swing. The bottom kicks out as it opens, so you can't park close, and a sloped driveway can get in the way.

Steel-Line lists what a tilt door does well: very low openings, a choice of materials, windows or other features, and running by hand if you'd rather not have an opener. It also lists the downsides. Cars have to park back a safe distance. An uneven or sloped driveway makes the door hard to open. The traditional look won't suit every modern home. And it can be expensive.

B&D doesn't sell tilt doors at all. It says they need a lot of room in front to swing open, that the outward swing is a hazard if the springs snap, and that the lack of side support leaves them open to wind damage, draughts and dents.

B&D's guide to garage door springs says extension springs are found on older and tilt door systems. They sit on either side of the door and stretch and pull back as it opens and closes. B&D says they carry a higher risk if they snap without safety cables.

Got a tilt door that works well? There's no need to rush out and replace it. RJ Garage Doors says a tilt door runs best when its springs and pivot arms stay balanced, and a regular garage door service checks that balance.

Question 05

Which garage door is quieter and better insulated?

A sectional door is the pick for insulation, because it can be made with insulated panels. Steel-Line says standard roller doors can't take insulated panels, since they have to roll up, although insulated aluminium slat rollers exist. Insulated panels also help keep outside noise out. But a worn or dirty door of any type is the loud one.

Steel-Line says insulated sectional panels can cut energy costs and reduce noise from outside. B&D offers insulation on its sectional doors to reduce noise as well. For roller doors, Steel-Line says weather seals and stripping can stop draughts, and B&D fits felt running strips along the edges of its roller doors for smooth, quiet running.

On the Sunshine Coast, insulation earns its keep when the garage sits under the house or shares a wall with a bedroom. It also helps a door that cops the afternoon sun. If the garage is a separate shed for the car and the mower, it matters a lot less.

A lot of the noise comes down to condition rather than type. Dirty guides, dry hinges, worn rollers and loose brackets all make a door louder. Steel-Line lists an excessively noisy door as one sign its tracks need cleaning. Noisy garage doors matches each sound to its likely cause.

Question 06

Which type of garage door handles strong wind best?

A wind-rated roller or sectional door. Roller doors come in wind-locked versions with clips that keep the curtain in its guides. Wind-rated sectional doors use heavy struts or removable brace posts. B&D says tilt doors are more prone to wind damage because they have no side support.

B&D says the clips on its wind-rated roller door keep the door in its track in high winds, which cuts the chance of it being forced open. Steel-Line builds wind-rated sectional doors two ways. One uses heavy-duty struts and hinges, so it needs no posts. The other uses removable steel posts that you fit to the door once a cyclone warning is issued.

Steel-Line's homeowner manual adds two points for roller doors. Windlocks should be fitted in high-wind areas, and they add security too. But a windlocked door with an opener shouldn't be run while it's windy.

Whether your home needs a wind-rated door, and how to check the one you've got, is covered in storm-ready garage doors.

Question 07

Which type of garage door is most secure?

Any of them is only as secure as its lock and its condition. B&D says its sectional panels offer excellent strength, and it sells an automatic bolt that locks the door every time it shuts. Roller doors lock with bars that slide into the guides. A bent door, or one left half open, is the weak spot.

B&D's roller door instructions show a centre lock with a bar on each side that slides through a slot in the guide. Steel-Line's homeowner manual says that if a roller door has an opener, or gets one later, the manual lock should be put out of action or removed.

• Shut it all the way. A door stopped a hand's width off the floor is an easy way in.
• Clear old remotes when you move in. The new home garage door checklist covers how.
• Get a bent or loose door fixed. A door that sits crooked may not lock or close properly.
• Lock it again after a blackout. If you've opened the door by hand, opening a garage door in a power outage explains how to lock it back up.

Question 08

What goes wrong with each type, and what does a service check?

Each type wears in its own spots. Roller doors lose spring tension and drag in dirty guides. Sectional doors wear their cables, drums, rollers and hinges, and their springs can break. Tilt doors wear their springs and pivot arms. A regular service checks the parts that matter on your door.

B&D's sectional door care notes tell owners to check the cables for rust, fraying or tangling, and to call for a service if they find any.

Every garage door service runs the same five checks: spring tension and balance, roller and track lubrication, hardware tightening, cable and drum inspection, and an opener and safety-reverse test. What each door needs most is different. On a roller door, the guides need to stay clean and free of grease, because B&D says grease or oil clogs the felt strips. On a sectional door, the cables and drums need a close look. B&D's care notes for both suggest a service by an experienced technician every 12 months, and more often in extreme conditions or with frequent use.

Question 09

What changes the cost of a roller, sectional or tilt door?

For a new door, size, type, finish, insulation and wind rating all move the price. Makers say roller doors usually cost less than sectional doors. For the door you've got now, repairs and servicing are booked as a callout valued between $200 and $300 depending on the door size and the labour involved.

What moves the price of a new door:

• Size. A double door takes more material than a single.
• Type. Steel-Line calls roller doors the most cost-effective option and says tilt doors can be expensive. B&D says a sectional door may need a little more budget.
• Extras. Insulated panels, windows, a wind rating or a custom finish all add to it. Steel-Line says a lot of add-ons can push up the cost of a sectional door.
• The job around the door. An opener, taking the old door away and any change to the opening all count.
