There's a room in a lot of Canberra homes that never quite gets enough light. A hallway with no window. A bathroom buried in the middle of the house. A kitchen facing the wrong way that needs the lights on at two in the afternoon. A skylight is usually the fix, and once people decide they want one, the next question is always the same: what's this going to cost.
Skylight installation cost is one of those numbers that's hard to pin down until someone has actually looked at your roof, because the roof changes the job as much as the skylight does. Here's a straight run-through of what skylights cost to put in around Canberra, what pushes the price up or down, and how to choose the right type for the room you're trying to brighten.
What skylights cost to install in Canberra
As a broad guide, and these are general market figures rather than a quote from us, a standard fixed skylight tends to run somewhere around $1,500 to $3,000 installed. A tubular skylight, the round kind that pipes light down through a reflective shaft, is usually cheaper, often in the $800 to $2,000 range. Opening or solar-powered models, the ones you can vent on a hot day, sit higher again, commonly $2,500 to $5,000 or more once the wiring and remote are sorted.
Swapping an old skylight for a new one of the same size is the cheapest version of the job, because the hole and the framing are already there. Cutting a brand new opening into a roof that has never had one costs more, since there's flashing to form, a light shaft to build, and on a tiled roof, tiles to cut and reseat.
What actually moves the price
When two skylight quotes come back a fair way apart, it usually means they have priced slightly different jobs. A handful of things swing the number more than the rest.
The type of skylight
A fixed pane of glass or a sealed dome is the simplest thing to install. Add the ability to open it, or a solar-powered blind and a rain sensor, and you're adding hardware, wiring and more that can go wrong later. More parts means more cost, both up front and over the life of the unit.
Tile or metal, and how the roof is built
Canberra roofs are mostly concrete tile, terracotta or Colorbond, and each one flashes up differently. A metal roof is often quicker, because the flashing folds neatly into the sheet profile. Tile takes more care: tiles get cut, the flashing is dressed in around them, and the whole thing has to shed water the way the rest of the roof already does. If you're weighing up roof types more generally, our look at how Colorbond and tile roofs compare is worth a read.
How far the light has to travel
The gap between your roof and your ceiling matters. In a single-storey home with a simple roof cavity, the shaft is short and straightforward. A room under a high or cut-up roof, or anything needing a long light shaft boxed and plastered down to the ceiling, adds framing and lining work that a plain skylight doesn't.
Access and storeys
Same as any roof work, a single-storey place with clear access is quick to get onto. A two-storey home, a steep pitch, or a roof hemmed in by trees means harnessing, ladders or a platform, and that setup time lands in the price.
Fixed, tubular or opening: which one suits the room
People often ask whether a sun tunnel or a proper skylight is better, and the honest answer is that they do different jobs.
A tubular skylight, or sun tunnel, is brilliant for a small dark space like a hallway, a walk-in robe or a windowless bathroom. It's cheaper, the light is surprisingly strong for the size, and because it's a sealed tube there's less that can leak. What it won't do is give you a view or that feeling of open sky.
A fixed glass skylight is the one most people picture. It floods a kitchen or living room with daylight and shows you the sky above. An opening skylight does all of that and lets heat and steam out, which is genuinely useful over a stovetop or in a bathroom that fogs up. It costs more, but in the right room it earns its keep.
Whichever type suits your place, the install is what makes or breaks it. Have a look at the skylight installation and leak repairs we handle across Canberra, on tile and metal roofs alike.
Do you need approval for a skylight in the ACT?
For most standard skylights going into an existing home, you generally won't need planning approval, since it's a minor change that doesn't alter the shape of the roof much. The exceptions worth checking are heritage-listed homes, unusually large openings, and anything that affects a shared wall or structure. If you're not sure, a good installer will flag it before they start, and it's cheap insurance to confirm rather than assume.
Why skylights leak, and how good ones don't
Skylights got a bad name years ago because early ones, badly flashed, did leak. A modern skylight installed properly should not. The leak almost never comes from the glass or the dome. It comes from the flashing, the metal collar that ties the skylight into the surrounding roof and carries water around it. Get that right and the unit stays dry for decades. Get it wrong and you'll see it as a brown stain spreading across the ceiling a season or two later.
This is roof plumbing work, not glazing, which is why it pays to have a licensed roof plumber form the flashing rather than treat a skylight as a window with a hole under it. We hold ACT Roof Plumber Licence 242220C, and the flashing is the part we won't rush.
A couple of things worth sorting before you book
If your roof is due for other work, think about timing. Getting a skylight cut in while a roofer is already up there for a restoration or a repair saves you paying twice for access. It's also the moment to check the tiles or sheets around the new opening are sound, because a skylight is only ever as watertight as the roof it sits in.
If a dark room in your place has been bugging you, the fix is usually simpler and tidier than people expect.
