The honest answer to "how much does a louvre roof or pergola cost?" is that it depends on five or six things you can pin down in a few minutes. This guide walks through each one, then lets you put your own measurements into our calculator for an instant estimate for your project, not a national average.

Outdoor structures are priced by the area they cover, so a 3 × 4 m cover over a back door and a 6 × 5 m roof over a full entertaining deck sit in very different brackets. Measure the width along the house and how far out from it you want the roof to reach, then multiply the two. That area is what the calculator below works from.
A fixed polycarbonate roof (our Elite Canopy) is the most economical way to keep rain off while letting 25–88% of the light through, depending on the tint. A metal roof gives complete shade and rain cover. An opening louvre roof uses motorised aluminium blades you can angle for sun or close flat against rain, and costs the most of the three because of the blade mechanism, motor and wiring.
Louvre roofs and outdoor blinds both come in manual and motorised versions. Motorised adds the motor, a remote or app control and an electrician’s sign-off, and options like a rain sensor that closes the roof automatically or integrated LED lighting add to that.
The roof is only part of the budget if you also want shelter from the side. Outdoor blinds, fixed glass or louvre panels, or a fully enclosed sunroom each add cost per side, but they are what turns a covered deck into a space you use through winter.
Some open pergolas and canopies don’t need building consent, while larger, roofed or enclosed structures can. Where consent or engineering is needed, the fees and drawings are part of the real cost, so ask every supplier whether their quote includes them. You can check your own project on the government’s Can I Build It? tool.
Ground conditions, the footings needed, whether the roof fixes to the house or stands free, access for materials, and the height of the attachment point all change the labour involved. These are why an onsite measure gives a firmer number than any online estimate.

If you want full sun on some days and a sealed roof on others, yes. If you mainly want rain cover with good light, a fixed polycarbonate canopy does that for less.
Because size, roof type and site conditions move the number so much that a single “from” price is usually wrong for your project. The calculator gives you an estimate for your own dimensions, and a free measure turns it into a fixed quote.
Most single-bay canopies are installed in one to two days once materials are on site. Louvre roofs take a little longer because of wiring and commissioning, and sunrooms longer again.
