Skylights range from a cheap tube that lights a hallway to a powered opening skylight that ventilates a room. Proper flashing and waterproofing at the roof is essential, a leaking skylight is a common and avoidable problem.
Ways to save
- A tube skylight is far cheaper if you just need daylight in a dark spot.
- Shorter, straighter shafts cost less, position matters.
- Use an installer who flashes and waterproofs properly, leaks are the main skylight complaint.
How we estimate this
Installing a skylight in Australia typically costs around $500 to $900 for a tube skylight in 2026, $1,200 to $2,500 for a fixed window skylight, and $2,500 to $4,000 for a powered opening skylight. The ceiling shaft length and roof type adjust the price.

What a skylight installation costs in Melbourne
A skylight in Melbourne is priced around the weatherproof opening cut in the roof and the lined shaft that drops daylight into the room, so the roof type and the shaft length set the figure rather than the glass alone. A tiled roof is cut and flashed differently from a metal one, and a single-storey home with a shallow ceiling cavity needs only a short shaft, while a two-storey home or a steep raked ceiling calls for a long light well that pushes the price up.
Bringing daylight into a dark room through the long, grey winter is a common Melbourne reason to fit a skylight, and a double-glazed glass roof window reduces the heat loss that a single-glazed unit lets slip on a frosty night. The flashing is the weatherproofing that counts, as the unit penetrates the roof, so it is roof plumbing work. A tube skylight funnelling light down a reflective shaft is the cheaper option against a glazed roof window. A powered openable skylight with a motor needs an electrician for the wiring. Many period and Victorian homes have dark central rooms a skylight brightens, and competitive trade labour just below Sydney's keeps the install reasonable.
A skylight install spans trades: the roof penetration and flashing are roof plumbing, the ceiling shaft and any structural trimming are a licensed builder's job, and a powered unit's wiring must be done by a licensed electrician in Victoria under the Victorian Building Authority. For a Melbourne home, the clearest way to price a skylight is by the roof type and the shaft length, with double glazing worth it for the winter and the flashing the critical weatherproofing.

Frequently asked questions
How is a skylight priced in Melbourne?
By the roof it cuts through and the ceiling-shaft run, because the cost is in the weatherproof roof opening and the lined shaft, so a two-storey Melbourne home or a steep raked ceiling with a long light well costs more than a single-storey shallow cavity.
Is double glazing worth it for a Melbourne skylight?
Often. A double-glazed glass roof window reduces the heat loss that a single-glazed unit lets slip on a frosty Melbourne night, which matters through the long, grey winter when a skylight is commonly fitted to brighten a dark room.
Why do period homes suit a skylight in Melbourne?
Because many period and Victorian Melbourne homes have dark central rooms with no external wall for a window, so a skylight brings daylight down through the roof, and the winter light gain is a common reason to fit one.
Do I need a licence for a skylight in Melbourne?
The roof penetration and flashing are roof plumbing and the ceiling shaft a licensed builder's job, while a powered or openable skylight's wiring must be done by a licensed electrician in Victoria under the Victorian Building Authority.
