Double and wide roller garage doors

A double roller garage door is a single roller curtain wide enough to cover a double garage opening, typically from 3 m up to about 5.5 m across, so one door replaces what might otherwise be two. It coils into one box above the opening and runs in a guide rail at each side. Wider curtains usually use larger laths for rigidity and are normally electric.

Can one roller door cover a double garage opening?

Yes, one roller curtain can span a double garage opening, and our price list covers single doors for openings up to about 5.5 m wide.

Because a roller door coils straight up into a box, it doesn't need the heavy frame and arms of a wide up-and-over door, and nothing swings out across the drive. The guide rails sit at each end of the opening, leaving the full width between them clear when the door is up.

What matters on a wide door is stiffness. A long curtain is more likely to flex than a short one, so wider doors usually use larger laths, around 77 mm, which add rigidity. That larger lath makes a bigger roll when the door is open, so the box needs more headroom too. Openings wider than 5.5 m are priced on survey, because the door, lintel and fixings need to be specified individually.

Is one wide door or two single doors better for a double garage?

One wide door gives you a single clear opening, while two single doors keep the central pier and let you open one side at a time.

If your garage already has one wide opening, a single wide roller door is the natural fit. If it has two openings separated by a brick pier, you can either fit two single doors or remove the pier to create one opening. Two doors keep the existing structure, each curtain is smaller and lighter, and if one door needs a repair you can still use the other.

Taking out a pier is structural work. It needs a lintel that spans the new opening and may need Building Regulations approval, so it's priced on survey and shown separately in your quote. Our guide to wide and double roller garage doors goes through the choice in more detail, and we'll talk it through with you at the survey.

How much does a double roller garage door cost?

An insulated electric roller door costs £2,195–£3,295 inc VAT for a double opening of 3.0 to 4.0 m, and £2,595–£3,995 inc VAT for a wide double of 4.0 to 5.5 m.

Other options for wide openings are:

Electric single-skin, 3.0 to 4.0 m: £1,795–£2,595 inc VAT
Electric single-skin, 4.0 to 5.5 m: £2,195–£3,195 inc VAT
Manual single-skin, 3.0 to 4.0 m: £1,395–£1,995 inc VAT
Steel electric, up to 4.0 m: £2,095–£3,095 inc VAT

Every price includes supply and fitting, commissioning for electric doors, and taking away your old roller or up-and-over door, with VAT at 20%. Battery backup adds £149–£279 inc VAT. Openings over 5.5 m, steel doors over 4 m, a new lintel and pier removal are all priced on survey, so your written quote shows each one as its own line.

What should I check before choosing a wide roller garage door?

Before choosing a wide roller door, check the lintel across the full span, the headroom for a larger box, the floor level from one side to the other, and the power supply.

Lintel: on a wide opening the box fixes along a long lintel, so any cracks, sagging or movement need to be dealt with first.
Headroom: a wider door often uses a larger lath, which makes a bigger roll and needs a deeper box.
Floor: a slope or dip across a wide opening can leave a gap under part of the bottom rail.
Side room: each guide rail typically needs around 75 to 100 mm of wall.
Power: an electric door needs a socket or fused spur near the box.

None of these will necessarily stop a wide door being fitted, but each can change the specification or add work, which is why we check them all at the free survey.

What happens at the survey and on fitting day for a double door?

For a double door, the survey takes the width, height and floor level at more than one point across the opening, and fitting day is about getting a long curtain into place and commissioning it.

Wide openings are rarely perfectly square, so we measure at several points and work to the narrowest. We also check access, because a curtain for a 5 m opening is long and needs a clear route from the van to the garage. After the survey you get a written quote, and once you accept it your fitting date is confirmed in writing, depending on installer availability.

On the day, the old door is removed and taken away. The box is fixed along the lintel, the guides are set level and parallel, and the curtain is hung. For an electric door, the installer sets the limits, tests the closing force and safety devices, and hands over the commissioning paperwork.

Questions about double and wide roller garage doors

Is a manual roller door practical on a double garage?

It can be, but only up to 4 m in our price list, and you'll be lifting a long curtain by hand each time, even with spring assistance. For a garage opened every day, or anyone who would find that hard work, an electric door is usually the better choice. Wide doubles between 4 and 5.5 m in our price list are electric.

Will a roller door give me more width than my double up-and-over door?

Possibly a little. An up-and-over door has a frame and swing-out arms at the sides, and a roller door doesn't, so converting can improve the clear width slightly. The guide rails still need some side room at each end. We measure the clear width you'd get at survey, so you know before ordering.

What if my garage opening is wider than 5.5 m?

We price it on survey. Openings over 5.5 m fall outside our standard price bands, because the door, the lintel and the fixing points need to be checked and specified individually. You can still use the online tool to tell us about the opening, and we'll arrange a free survey and give you a written quote.

Do I need permission to turn two garage openings into one?

Removing a pier and fitting a longer lintel is structural work, and it may need Building Regulations approval. Whether planning permission is needed depends on your property, so check with your local authority, especially for listed buildings or homes in a conservation area. Our guide to planning and building regulations covers the questions to ask.

Can I convert a double up-and-over door to a roller door?

Yes. We remove the old door and its frame, or keep the frame if it's sound, then check the lintel and reveals. The box is fitted behind the lintel and the guides to the reveals. Any extra work, such as a new lintel or building out the reveals, is priced on survey and listed separately in your written quote.
