What does an aluminium pergola cost in South Africa?

An aluminium pergola is one of the more affordable ways to put a proper engineered roof over a patio, and the pricing is simpler than most people expect. Ours start from R3 000 per square metre, supplied and installed. In this guide we work through what that means for a typical patio, what pushes the number up or down, and how it stacks up against composite pergolas and louvre roofs.

Where the number starts

Our extruded aluminium pergolas start from R3 000 per square metre, supplied and installed. One rate, covering the structure, the roof and the labour. There is no separate installation bill waiting at the end, and no kit standing on your driveway that still needs a builder.

That from-rate buys the entry configuration: a straightforward span, a standard colour and a clean fixing surface. Every project is quoted individually after a free site visit, because the things that move the number are physical and specific to your house. A pergola bolted to a double-storey wall in Constantia prices differently to a freestanding one on an exposed Langebaan plot, and a from-rate cannot know that.

What a typical patio works out at

The arithmetic is worth doing before anyone visits. A 4 x 5 m patio is 20 square metres, which puts the starting point at around R60 000. A smaller 3 x 4 m courtyard is 12 square metres, so from about R36 000. A generous 6 x 4 m entertainment area comes to 24 square metres, from roughly R72 000.

Treat those as orientation figures, not quotes. They tell you which league you are shopping in, and that is exactly what they are for. If the space is an odd shape, measure the rectangle you actually want covered; the rate applies to roof area, not paving.

What moves the price

Two pergolas with the same footprint can land on quite different numbers. These are the things we price when we walk a site:

• Size and span. More area means more total cost, but long unsupported spans are the real driver: they call for heavier profiles and extra posts.
• Roof choice. Fixed multiwall polycarbonate gives a fully watertight roof with soft, filtered light. Retractable shade fabric opens the whole space to the sky on good days. They carry different prices.
• Colour and finish. Standard baked-enamel colours sit at the entry point; special powder-coat colours add a little.
• Footings and fixing. Bolting into a sound wall is the simple case. Freestanding structures need footings, and some older walls want reinforcement before they can carry a roof.
• Site access. A ground-floor stoep with side access installs quickly. A third-floor terrace where every length comes through the house takes longer, and time is money.

How it compares with composite pergolas and louvre roofs

Of the pergola family we build, the extruded version is the entry point. Composite pergolas start from R3 500 per square metre and give you a timber look with none of the sanding, sealing or rot that real wood demands. On that 4 x 5 m patio the step up is about R10 000 at the starting rates, and it earns its keep where the structure has to sit against a deck or a farm-style home.

A louvre roof starts from R3 200 per square metre, roughly R4 000 more on the same patio. For that you swap a fixed roof for rotating aluminium blades: open for sun and airflow, closed for around 95% weatherproof cover with integrated gutters, and you can add motorised operation with rain and wind sensors. If you want one space that adapts through the day, the step up is small over the life of the structure. If all you need is permanent watertight cover, the polycarbonate pergola does it for less.

What the price includes

The rate is not a materials price. It includes measurement and design, engineering for wind (everything we build is specified for the Cape Doctor, which regularly tops 80 km/h), fabrication in marine-grade aluminium with stainless fasteners and no ferrous metal, installation by our own teams, and a lifetime corrosion guarantee on the aluminium. Anywhere near the coast, that last line is the one that matters in year ten.

When you compare quotes, compare what sits inside them. A cheaper number that leaves out the engineering or the guarantee is a different product, not the same one at a better price.

Getting a real number

The instant estimator on our pricing page takes your dimensions and roof choice and gives an indicative figure. It is a useful way to sanity-check a budget before you commit to anything.

For the real number, arrange a free site visit. We measure, check the fixing surface and access, talk through polycarbonate versus retractable fabric, and send a fixed written quote within 48 hours. The number on that quote is fixed, so what you accept is what you pay. Lead time from acceptance is 4 to 5 weeks to installation.

FAQ

How much does a 4 x 5 m aluminium pergola cost?

At the starting rate of R3 000 per square metre, a 20 square metre pergola works out from about R60 000 supplied and installed. The final figure depends on roof choice, span and site, so we confirm it with a fixed quote after a free site visit.

Is an aluminium pergola cheaper than a louvre roof?

As a starting point, yes. Extruded aluminium pergolas start from R3 000 per square metre against R3 200 for a louvre roof, and motorisation and sensors on a louvre roof add further to that.

Does the per square metre price include installation?

Yes. Our rates are supplied and installed, and they include design, wind engineering and the lifetime corrosion guarantee on the aluminium.

How long does an aluminium pergola take from order to install?

Allow 4 to 5 weeks from accepting the quote to installation. The quote itself arrives within 48 hours of the free site visit.
