If you’ve been thinking about adding a skylight to your home, the first question is usually the same: how much will this actually cost me?
Skylight installation prices depend on a few factors: the type of skylight you choose, the complexity of your roof, and how many units you install. This guide breaks down what you can expect to pay for different types of skylights on the Sunshine Coast, as well as the factors that influence the final price.
Skylight Types and How They Affect Cost
Not all skylights are the same, and the type you choose is the biggest factor in your overall skylight installation cost.
Fixed Skylights
Fixed skylights are permanent, sealed openings in your roof that let in natural daylight.
They do not require opening or ventilation, which makes them a straightforward and cost-effective choice.
They work well in living areas, hallways, and bedrooms.
Manual Opening Skylights
Ventilated skylights open manually to bring fresh air and natural light into your home.
Because they include moving parts and sometimes mechanical components, skylight installation prices are generally higher than those for fixed units.
Solar-Powered Alternatives
We also supply the solar-powered skylight alternatives with an LED system that mimics natural daylight without any roof penetration.
No shaft means no leaking, no heat transfer, and no bugs on the diffuser. It is ideal for multi-storey homes, south-facing rooms, or spaces where a traditional skylight would be difficult to install — and because installation is less complex, it is often more affordable.
What Affects the Cost of Skylight Installation?
Beyond product type, several factors influence the final skylight installation cost:
- Roof type and pitch: Tiled, metal, and flat roofs each need different flashing; steeper pitches add to labour time
- Ceiling height and shaft length: Deeper ceiling cavities mean longer shafts and more materials
- Electrical connections – Required for electric or solar powered skylights with blinds, sensors, or remote operation, as well as optional AC connection on illume systems.
- Number of units: Installing multiple skylights at once is generally more cost-efficient per unit
- Glazing and features: Double glazing and UV protection add to product cost but reduce heat gain, which matters in Queensland
- Access and complexity: Unusual roof structures or hard-to-reach areas may increase labour
VELUX and Illume: Two Products Worth Knowing About
VELUX Skylights
VELUX skylights are built to a high standard and come in fixed, manually operated, and solar-powered opening styles. Key features include double glazing to reduce heat transfer, solar-powered motorisation with no wiring required, automated rain sensors on select models, and strong year-round energy efficiency.
They suit homes where roof access is straightforward and where you want a long-lasting product with broad design options. Suncoast Skylights is an authorised VELUX dealer, so you get genuine products backed by the manufacturer’s warranty.
Illume™ Skylight Alternative
The illume™ system uses a rooftop solar panel to power an LED ceiling light that looks and feels like natural daylight, with no roof penetration required. It is particularly well suited to:
- Multi-storey homes: work in lower-level rooms without a shaft
- South-facing rooms: The solar panel sits on the north-facing roof and connects to any room
- Rooms with obstructions: Installs under beams, trusses, plumbing, or wiring
- Bedrooms: Can be switched off or wired to AC for night use
- Multiple rooms: Up to nine illume units run off a single solar panel
For homes where a traditional skylight is not practical, or where older skylights have caused heat or leak issues, Illume is a practical, purpose-built solution.
What Does It Cost to Replace an Existing Skylight?
The cost to replace a skylight is generally similar to a new installation. The old unit needs careful removal to avoid roof damage, and the opening may need to be re-flashed or relined.
Many homeowners use this as an opportunity to switch to the Illume™ system, eliminating the heat and condensation issues common with older products.
