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

What a skylight installation costs in Sydney
A skylight in Sydney is costed around cutting a weatherproof opening in the roof and lining the shaft that brings daylight down to the room, so the roof type and the shaft length drive the figure more than the glass itself. Cutting and flashing a tiled roof differs from a metal roof, and a single-storey home with a short ceiling cavity is a quick shaft, while a double-storey home or a high raked ceiling needs a long lined light well that lifts the cost.
The flashing is the part that matters most in Sydney, because the skylight penetrates the roof and a poorly flashed unit leaks, so the roof-penetration and flashing are roof plumbing work. A tube-style skylight that funnels light through a reflective shaft is cheaper than a glazed roof window, which can be fixed or openable. An openable or powered skylight with a motor and rain sensor adds an electrician for the wiring, and salt air near the coast favours corrosion-resistant flashing on an eastern-suburbs home. The city's highest trade rates lift the labour, and a heritage terrace may need a low-profile unit to suit the streetscape.
A skylight install crosses 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 New South Wales under NSW Fair Trading. For a Sydney home, the clearest way to price a skylight is by the roof type and the shaft length, with the flashing the critical weatherproofing and a powered unit adding electrical work.
