You have got one room in the house that never quite wakes up. A hallway with no windows, a bathroom that needs the light on at lunchtime, a kitchen that feels gloomy even when the sun is out. A skylight sorts that out, often in a single afternoon, and the first thing most people want to know before they ring anyone is simple: what does it cost.
Skylight installation cost on the Mornington Peninsula usually lands anywhere between a few hundred dollars and several thousand, and that spread is not us being cagey. It genuinely depends on the type of skylight, what your roof is made of, and how far the light has to travel from the roof down into the room. Here is how the numbers break down, and what actually moves them.
The honest price range, by type of skylight
There are really four kinds of skylight, and they sit at very different price points. The figures below are typical fully installed ranges across Australia. They are not a quote, but they will tell you which ballpark you are in before anyone climbs on your roof.
- Tubular skylights are a small dome on the roof feeding a reflective tube down into the room. They run around $800 to $2,000 installed, and basic units for a hallway or laundry can start lower. This is the cheapest way to get daylight into a small, dark space.
- Fixed skylights are a sealed glass or acrylic panel that does not open. Expect roughly $1,200 to $5,000 installed. This is the usual choice for living rooms and kitchens where you want as much light as the room can take.
- Opening skylights that you crank open by hand sit around $1,800 to $4,500. You get the light plus a way to let hot air escape, which is worth having through a Peninsula summer.
- Electric and solar skylights, often with a rain sensor that shuts them for you, start near $4,000 and can climb past $8,000 for high or awkward ceilings.
You will also spot eye-catching figures like “from $259” advertised by the big hardware chains. That price is usually the labour to fit one specific budget product, not the finished job with the light shaft lined and painted. Always read what is actually included before you hold it up against anything else.
Why one quote can be double another
Two installers can look at the same dark bathroom and come back with prices hundreds of dollars apart, and neither is necessarily overcharging. They are pricing different amounts of work. A handful of things move the number far more than the skylight unit itself.
What your roof is made of
Cutting and flashing a tiled roof is slower and fiddlier than a metal roof, so a tile roof generally adds a few hundred dollars to the job, often in the $200 to $500 range. On the Peninsula we see plenty of both: concrete tile on a lot of the older brick homes through Mornington and Mount Martha, and Colorbond on newer builds, extensions and beach houses. The flashing (the metal collar that seals the skylight to the roof and keeps water out) has to suit whichever one you have, and getting that right is what stops a skylight leaking down the track.
How far the light has to travel
This is the part people miss. A flat ceiling sitting right under the roof is a short, simple shaft. A double-storey home, a raked ceiling, or a deep roof cavity means building and lining a longer shaft, then plastering and painting it so it looks like it belongs. That internal work is often the biggest hidden cost, and it is how a quick bathroom skylight quietly grows into a bigger job. When you compare quotes, check whether the shaft, plastering and paint are in the price or left for you to sort out.
Access and roof pitch
A single-storey home with a gentle pitch is straightforward. A steep roof or a two-storey job needs more safety gear, sometimes scaffold, and more time up top. That extra time shows up in the price, and it should, because rushing height work is how people get hurt.
Tile or metal: what it means around here
Most Peninsula homes fall into one of two camps, and the difference matters for both the cost and the finish. On a tile roof the installer lifts and cuts tiles, fits the skylight, then flashes and re-beds around it. On a Colorbond or metal roof it is a cleaner cut, but the flashing detail still has to be spot on so wind-driven rain has nowhere to sneak in. Either way this is roof work, not just a window fitted from inside, which is why it pays to have an actual roofer do it rather than a general handyman. If you want to talk through the options for your place, our skylight installation service across the Mornington Peninsula covers both roof types and the internal shaft work in one go.
Do skylights add value, and are they worth it?
Natural light is a genuine drawcard when you sell, and buyers notice a bright, open room straight away. Day to day, a well-placed skylight cuts how often you flick a light on, and an opening one helps a stuffy bathroom or kitchen clear the air. So yes, most people who add one are glad they did.
The catch is that a skylight is only as good as its install. A unit that fogs up, or worse, one that leaks around the flashing, does the opposite of adding value. Skylights are one of the more common spots we trace water back to, so if you already have one playing up, it is worth reading why a roof tends to leak only in heavy rain before it does any real damage. A tidy skylight repair is a lot cheaper than a ceiling replacement.
Do you need council permission?
For a standard house, fitting a skylight into an existing roof is usually treated as maintenance-level work and does not need a planning permit. There are exceptions worth knowing about. If your property sits under a heritage overlay, or you are cutting into a shared roof on a unit or townhouse, the rules can be different. When in doubt, a quick call to Mornington Peninsula Shire will tell you where you stand, and any decent installer will flag it if they think a permit is in play.
What we check before we give you a price
Before we quote, we look at the room you want brightened, your roof type and pitch, how deep the shaft will need to be, and where the framing runs so the skylight lands in a clean spot. That is what lets us give you a real number instead of a guess, and it is why an on-site look beats a phone estimate every time. If you have got a dark room in mind anywhere from Mount Eliza down to Rye, we are happy to come and take a look.

Common questions about skylight costs
How much does Bunnings charge to install a skylight?
Bunnings advertises skylight installation from around $259 for a solar hybrid unit and from about $419 for a flexishaft model. Those prices are for fitting a specific product and do not usually include extras like a deep shaft, plastering or painting, so the finished cost can be higher. Check exactly what the quote covers.
Do skylights add value to a house?
They can. A brighter, more open room is an easy selling point, and skylights are a relatively low-cost way to lift a dark space. The value only holds if the install is watertight, because a leaking or fogged skylight puts buyers off rather than on.
Do I need planning permission to put a skylight in my roof?
For most standard homes, no, because it is usually classed as maintenance-level work rather than a change to the building. Heritage overlays, unit blocks and shared roofs can change that, so check with Mornington Peninsula Shire if you are unsure before booking anything in.
Which is cheaper, a tubular skylight or a glass one?
Tubular skylights are generally the cheaper option, often from around $800 installed, and they suit small dark rooms like hallways and bathrooms. A fixed glass skylight lets in more light and looks more architectural, but it costs more and usually needs a lined shaft.
Do skylights leak?
A properly flashed skylight should not leak for many years. Most leaks we find come from poor flashing at install time or old seals that have perished, not the glass itself. Getting a roofer to do the flashing correctly is the single biggest thing that keeps a skylight dry.
How long does it take to install a skylight?
A simple fixed or tubular skylight on a single-storey home is often a one-day job. If the shaft is deep, or the ceiling needs plastering and painting once the skylight is in, allow an extra day or so for that internal work to be finished properly.
