What Affects Skylight Installation Cost?
- Skylight type: The biggest driver of price is the product you choose. Tubular units start at $1,200 AUD each, fixed glass skylights are $2,200 AUD, vented / opening skylights are $3,200 AUD, and electric vented skylights are $4,200 AUD, while replacing a skylight dome or glazed unit on an existing opening is $750 AUD.
- Roofing skylight conditions: Roof type changes the install rate for a roofing skylight because tile roofs are more labour-intensive than metal roofs. Use the metal-roof single-storey base rates, then apply ×1.2 for tile roofs or ×1.35 for steep, 2-storey or hard-access jobs.
- Number of skylights: This calculator works on a per-unit basis, so the skylight cost and installation total increases with each additional skylight. For example, two fixed glass skylights on a standard metal single-storey roof would be double the per-unit rate before any optional add-ons.
- Optional finishing work: Extras can lift the final price to install skylight projects even when the roof work stays the same. A skylight blind / shade adds $650 AUD per job and interior plaster make-good adds $900 AUD per job, and these are flat job costs rather than per-skylight charges.
Skylight Installation Cost - Frequently Asked Questions
For a typical job with 1 skylight on a single-storey metal roof, prices start at $1,200 AUD for a tubular / solar tube, $2,200 AUD for a fixed glass skylight, $3,200 AUD for a vented / opening skylight, and $4,200 AUD for an electric vented skylight. If you’re only replacing an existing dome or glazed unit, the cost is $750 AUD. Estimate ranges are usually shown at around ±15% of the midpoint.
A fixed glass skylight is priced at $2,200 AUD per skylight for supply and installation on a single-storey metal roof. If the job is on a tile roof, apply the ×1.2 multiplier, and if access is steep, 2-storey or difficult, apply ×1.35. Optional extras like a blind ($650 AUD) or interior plaster make-good ($900 AUD) are added per job.
The cost to add skylight units depends on the style selected. A tubular / solar tube is $1,200 AUD each, a vented / opening skylight is $3,200 AUD each, and an electric vented skylight is $4,200 AUD each on a standard metal single-storey roof. These prices are per skylight before roof access multipliers and optional add-ons.
To work out the cost to put in skylight units on a tile roof, use the base per-unit price and apply the tile roof multiplier of ×1.2. That means a tubular skylight becomes $1,440 AUD, a fixed glass skylight becomes $2,640 AUD, a vented / opening skylight becomes $3,840 AUD, and an electric vented skylight becomes $5,040 AUD. Per-job extras like blinds and plastering are then added on top if needed.
If the existing opening can be reused, the cost to replace skylight units is much lower than a new cut-in. Dome / unit replacement only is priced at $750 AUD per skylight on a single-storey metal roof. This is the standard rate for replacing a skylight dome or glazed unit without creating a brand-new opening.
Skylight installers cost more for opening models because the unit and installation are more complex. A manual or basic vented skylight is $3,200 AUD each, while an electric vented skylight is $4,200 AUD each on a single-storey metal roof. If the roof is steep, 2-storey or hard to access, apply the ×1.35 multiplier to those base rates.
