Planning to install a skylight in your Melbourne home? One of the first questions most homeowners ask is: how much does skylight installation cost in Melbourne in 2026?
As a general guide, a professional skylight installation in Melbourne usually costs between $2,500 and $6,500+ per skylight, depending on the skylight model, roof type, ceiling height, shaft depth, access, flashing requirements and internal finishing work.
A simple fixed skylight on a standard single-storey roof will usually sit at the lower end of the range. A solar opening VELUX skylight, flat roof installation, high ceiling, deep plaster shaft, double-storey home or complex roof detail will usually cost more.
At Central Skylights, we supply and install quality VELUX skylights across Melbourne, with professional roof work, custom flashing, internal framing and plaster shaft finishing included where quoted. This guide explains the typical 2026 costs, what affects your quote, and how to avoid hidden surprises when comparing skylight prices.

Why Our Skylight Cost Guide May Look Higher Than Some Quotes
Some skylight prices online only cover the product or basic roof installation. A proper Melbourne skylight installation often includes more than that: the VELUX skylight, correct flashing, roof work, shaft framing, plastering and sanding.
At Central Skylights, we prefer to explain the real finished cost upfront, so you know what is included before comparing quotes. Painting is usually excluded, but the skylight, roof installation, shaft and plaster finishing are clearly allowed for in a complete quote.
Always compare what is included — product only, roof-only install, or fully finished installation!
| Skylight Type | Supply Only Price | Fully Installed Price | Best Suited For |
|---|---|---|---|
| VELUX FS Fixed Glass Skylight | $450 – $1,200 | $2,500 – $4,000 | Living rooms, hallways, lounges, bedrooms, stairwells |
| VELUX VS Manual Opening Skylight | $800 – $1,600 | $3,200 – $4,800 | Bathrooms, kitchens, laundries and rooms needing ventilation |
| VELUX VSS Solar Opening Skylight | $1,500 – $2,600 | $4,500 – $6,500+ | High ceilings, premium homes, open-plan extensions |
| Sun Tunnel / Tubular Skylight | $400 – $700 | $1,200 – $2,200 | Walk-in robes, small toilets, pantries and narrow hallways |
Important: A cheap skylight quote may only include the roof installation. It may not include internal carpentry, plaster shaft work, sanding, clean finish, custom flashing or painting. Always check exactly what is included before comparing prices.
Supply Only vs Fully Installed Skylight: What Is the Difference?
When searching online for skylight prices, you will usually see two very different types of pricing: supply only and fully installed.
Supply Only Skylight Cost
Supply only means you are buying the skylight unit, and sometimes the flashing kit, but you still need someone else to install it. This may suit builders, roof plumbers, owner-builders or renovation projects where trades are already organised.
Supply only may include:
- VELUX skylight unit
- Flashing kit, if selected
- Blind or accessory, if purchased
- Delivery or pickup options
Supply only does not normally include:
- Cutting the roof
- Structural framing
- Waterproofing installation
- Building a light shaft
- Plastering
- Internal finishing
- Site clean-up
- Warranty on workmanship by the installer
Fully Installed Skylight Cost
A fully installed skylight is a complete service where the skylight is supplied, installed, waterproofed and finished internally according to the quote.
A proper full-service installation may include:
- Skylight supply
The selected VELUX skylight model, size and glazing option. - Flashing and waterproofing
Correct flashing for tiled roof, corrugated metal roof, Colorbond roof or flat roof detail. - Roof work
Cutting the roof opening, fitting the skylight and making the roof watertight. - Structural carpentry
Framing and reinforcing the opening where required, without compromising roof structure. - Internal shaft construction
Building the light shaft from the roof opening down to the ceiling line. - Plastering and sanding
Plasterboard, setting, corners and sanding so the shaft is ready for painting. - Final inspection and clean finish
A neat, finished skylight installation that looks integrated with your home.
At Central Skylights, we focus on complete skylight solutions, not just dropping a skylight into the roof and leaving the inside unfinished.
Why Skylight Installation Costs Vary So Much
No two Melbourne homes are exactly the same. A skylight installed in a single-storey Colorbond roof in Berwick may be very different from a skylight installed in an old tiled terrace house in Fitzroy, a flat roof extension in Richmond, or a double-storey home in Brighton.
Here are the main factors that affect your skylight installation quote.
1. Skylight Type: Fixed, Manual, Solar or Sun Tunnel
The model you choose is one of the biggest cost factors.
Fixed Skylights
A fixed skylight is the most cost-effective glass skylight option. It brings natural light into the room but does not open for ventilation. Fixed skylights are ideal for:
- Dark hallways
- Living rooms
- Bedrooms
- Stairwells
- Dining rooms
- Walk-in robes
- Lounge areas
For many Melbourne homes, a fixed VELUX skylight gives the best balance of price, daylight and energy performance.
Manual Opening Skylights
A manual opening skylight costs more than a fixed skylight because it includes an opening mechanism. It is a great choice for rooms that need natural ventilation. Manual opening skylights are ideal for:
- Bathrooms
- Kitchens
- Laundries
- Ensuites
- Rooms with moisture or steam
- Smaller rooms that feel stuffy
If the skylight is installed within reach, a manual opening skylight can be a practical and affordable upgrade.
Solar Opening Skylights
A solar opening skylight is a premium option. It is usually operated by a wall switch or remote control and is ideal when the skylight is installed high above the floor. Solar opening skylights are popular for:
- High ceilings
- Open-plan living areas
- Stairwells
- Premium renovations
- Hard-to-reach skylight locations
- Homes wanting light and ventilation without manual operation
Many homeowners choose solar opening skylights because they provide both natural light and controllable airflow.
Sun Tunnels
A sun tunnel, also called a tubular skylight, is usually more affordable than a full glass skylight. It captures daylight from the roof and transfers it through a reflective tube into a smaller room. Sun tunnels are ideal for:
- Walk-in robes
- Pantries
- Small toilets
- Internal bathrooms
- Narrow hallways
- Small laundry areas
A sun tunnel is a good solution when a full skylight shaft is not practical or when the room is small.
2. Roof Type: Tile, Metal, Colorbond or Flat Roof
Your roof material has a major impact on cost and installation method.
Tiled Roof Skylight Installation
Many older Melbourne homes have terracotta or concrete tiled roofs. These roofs require careful handling because tiles can crack if cut or walked on incorrectly.
Tiled roof skylight installation may require:
- Tile removal and cutting
- Tile flashing
- Careful waterproofing
- Replacement of damaged or brittle tiles
- Extra time around older roof sections
Tiled roofs are common in suburbs such as Kew, Camberwell, Balwyn, Glen Iris, Brighton, Malvern, Essendon and many established Melbourne areas.
Metal and Colorbond Roof Skylight Installation
Metal and Colorbond roofs are common across Melbourne extensions, townhouses and newer homes. In many cases, they can be faster to work with than tiled roofs, but the flashing must be correct.
Metal roof skylight installation may require:
- Corrugated roof flashing
- Custom Colorbond flashing
- Correct sealants and fixings
- Proper water flow planning
- Careful positioning between roof ribs
A good installer will not simply seal around the skylight with silicone and hope for the best. Correct flashing is what protects your home during Melbourne’s heavy rain and sudden weather changes.
Flat Roof Skylight Installation
Flat roof skylights are common on modern extensions, especially in inner Melbourne suburbs such as Richmond, Carlton, Fitzroy, Brunswick, Port Melbourne, South Melbourne, Prahran and South Yarra.
Flat roofs need special care because water does not run away as quickly as it does on a pitched roof. A proper flat roof skylight installation may require:
- An insulated kerb or upstand
- Custom flashing
- Correct fall for water runoff
- Weatherproof detailing
- Careful drainage planning
Flat roof skylights often cost more than simple pitched roof installations because the waterproofing detail is more specialised.
3. Roof Pitch and Skylight Position
Roof pitch affects both the skylight model and the flashing required.
A standard pitched roof usually allows for more straightforward skylight placement. A very low-pitch roof, flat roof, steep roof or complex roofline may require a more customised solution.
Skylight position also matters. The installer needs to consider:
- Roof rafters or trusses
- Electrical cables
- Ducted heating or cooling
- Plumbing pipes
- Solar panels
- Roof valleys
- Gutters and water flow
- Ceiling joists
- Internal room layout
The best skylight location is not always the easiest roof location. A good installer will balance roof practicality, daylight performance and how the skylight looks inside the room.
4. Ceiling Height and Shaft Depth
The internal shaft is the tunnel between the skylight on the roof and the ceiling inside your home.
A shallow ceiling cavity is usually quicker and cheaper to finish. A deep ceiling cavity needs more timber, plasterboard, setting, sanding and labour.
A deeper shaft may be needed in homes with:
- High ceilings
- Roof cavities
- Double-storey sections
- Older roof structures
- Extensions with unusual ceiling lines
- Vaulted or raked ceilings
- Large distance between roof and ceiling
The shaft shape also matters. A straight shaft is usually simpler. A splayed shaft, wider light well or angled shaft can improve daylight spread but may require more labour.
5. Single Storey vs Double Storey Homes
Most standard skylight cost guides assume a single-storey home with safe roof access.
Double-storey homes usually cost more because they may require:
- Additional safety equipment
- More labour
- More difficult roof access
- Higher risk work controls
- Longer installation time
- Extra care moving materials
If your home is two storeys, built on a slope, or has limited access down the side of the house, the quote may be higher.
6. Internal Finish: Is Plastering Included?
This is one of the biggest hidden cost differences between skylight quotes.
Some installers only install the skylight into the roof. After they leave, the homeowner still needs to organise a carpenter, plasterer and sometimes another trade to finish the inside.
A complete skylight installation should clearly state whether it includes:
- Shaft framing
- Plasterboard
- Setting
- External corners
- Sanding
- Ready-for-paint finish
Painting is often not included unless specifically quoted. Many homeowners prefer to paint the shaft themselves or have their own painter complete it during a renovation.
Before accepting a quote, ask: Will the inside of my ceiling be fully plastered and ready for painting?

Example Skylight Installation Scenarios in Melbourne
Example 1: Fixed Skylight in a Dark Hallway
A homeowner in a single-storey brick veneer home wants more daylight in a dark central hallway. The roof is pitched metal and the ceiling cavity is standard.
Typical cost range: $2,500 – $3,800
This type of job is usually one of the most cost-effective ways to brighten a home because a fixed skylight is simple, reliable and does not need an opening mechanism.
Example 2: Manual Opening Skylight in a Bathroom
A bathroom has no external window and feels damp after showers. The homeowner chooses a manual opening VELUX skylight to bring in both daylight and ventilation.
Typical cost range: $3,200 – $4,800
The cost depends on roof access, ceiling height and whether the skylight is within easy reach for manual operation.
Example 3: Solar Opening Skylight in an Open-Plan Extension
A modern rear extension has a flat or low-pitch roof and a high ceiling. The homeowner wants natural light, ventilation and easy remote operation.
Typical cost range: $4,500 – $6,500+
This type of installation usually costs more because it may involve a premium solar opening skylight, specialised flashing and a more detailed internal finish.
Example 4: Sun Tunnel in a Walk-In Robe or Pantry
A small internal room does not need a full skylight but needs daytime light. A sun tunnel is installed to bring daylight into the space.
Typical cost range: $1,200 – $2,200
Sun tunnels are often a practical option for small spaces where a full skylight is not necessary.
Which Rooms Benefit Most from Skylights?
Skylights are especially useful in Melbourne homes where side windows are limited, neighbouring houses are close, or the room sits in the middle of the floor plan.
Hallways
Hallways are one of the most popular places for skylights. Many Melbourne homes have long, dark central corridors that rely on artificial light during the day. A fixed skylight can make the entire home feel brighter as soon as you walk in.
Kitchens
Kitchens benefit from both daylight and ventilation. A skylight above a kitchen bench, island or dining area can make the room feel larger, cleaner and more welcoming.
Bathrooms
Bathrooms often need extra light and ventilation. A manual or solar opening skylight can help release steam and reduce the stuffy feeling common in windowless bathrooms.
Living Rooms
A skylight can transform a living room by bringing soft daylight from above. This is especially useful when windows face fences, neighbouring walls or shaded outdoor areas.
Walk-In Robes and Pantries
Small internal rooms often do not need a large skylight. A sun tunnel can provide enough daylight to make the room more usable during the day.
Stairwells
A skylight above a stairwell can send daylight through multiple levels and make the centre of the home feel more open.
Do Skylights Make Melbourne Homes Hotter in Summer?
A properly selected, high-quality glass skylight should not be compared with old acrylic domes or cheap plastic roof lights.
Modern VELUX glass skylights use high-performance glazing designed to reduce heat transfer while still bringing natural light into the home. For even better heat control, many homeowners add solar-powered blinds or blockout blinds, especially for north-facing or west-facing roofs.
Good skylight performance depends on:
- Correct skylight size
- Correct room placement
- Roof orientation
- Quality glazing
- Internal blind selection
- Proper shaft design
- Professional installation
The goal is not just to add more light. The goal is to add the right amount of controlled daylight without creating glare or unwanted heat.
Are Skylights Worth the Cost?
For many Melbourne homes, yes. A well-installed skylight can improve the way a home feels every day.
The main benefits include:
- More natural daylight
- Less reliance on artificial lights during the day
- Better airflow with opening models
- A more open and spacious feeling
- Improved appearance of hallways, kitchens and bathrooms
- Better liveability in dark internal rooms
- A premium finish for renovations and extensions
A skylight is not just a roof window. When installed properly, it becomes part of the architecture of the home.
How to Avoid Cheap Skylight Installation Problems
A cheap skylight installation can become expensive if it leaks, looks unfinished, or causes problems with the roof structure.
Before choosing an installer, ask these questions:
- Is the flashing included?
- Is the flashing suitable for my roof type?
- Is internal shaft framing included?
- Is plastering included?
- Is painting included or excluded?
- Will the installer inspect the roof cavity first?
- What happens if pipes, ducts or wiring are in the way?
- Is the installer experienced with VELUX skylights?
- Is the quote for a complete finish or roof-only installation?
- Does the installer understand Melbourne roof types and weather conditions?
The cheapest quote is not always the best value. A proper skylight installation needs roofing knowledge, carpentry knowledge, waterproofing experience and a good internal finish.
Do You Need a Permit for a Skylight in Melbourne?
In many standard residential situations, a skylight may be a straightforward home improvement. However, permit requirements can depend on your property, the extent of structural work, council rules and whether your home is affected by a heritage overlay.
You should check before installation if:
- Your home is in a heritage overlay area
- The skylight is visible from the street
- Major structural beams may be altered
- The home is part of a body corporate or owners corporation
- The property is a townhouse, apartment or multi-unit development
- The project is part of a larger renovation or extension
Older suburbs such as Fitzroy, Carlton, Richmond, Kew, Hawthorn, South Melbourne, Port Melbourne, Brunswick and parts of Brighton may have more planning considerations, especially for heritage homes.
If you are unsure, speak with your local council, builder, building surveyor or skylight specialist before proceeding.
How Long Does Skylight Installation Take?
A standard single skylight installation usually takes 1 to 2 days, depending on the roof, weather, ceiling depth and internal finishing requirements.
A simple roof-only installation may be faster, while a fully finished skylight with framing and plastering can take longer.
Installation time may increase if:
- The roof is steep or difficult to access
- The ceiling cavity is deep
- Multiple skylights are being installed
- The home is double storey
- The roof is tiled and fragile
- Ducts, wiring or pipes need to be relocated
- Weather conditions are unsafe
Melbourne weather can also affect timing. Roof work needs to be done safely and waterproofed correctly, so heavy rain or high wind may cause delays.
Can You Install More Than One Skylight at the Same Time?
Yes. Installing multiple skylights at the same time can be a smart choice because the team is already on site.
Common multi-skylight projects include:
- Two skylights in a large living room
- One skylight in the hallway and one in the bathroom
- Multiple skylights in an open-plan extension
- Skylights across a kitchen and dining area
- Matching skylights along a corridor
- A combination of glass skylights and sun tunnels
If you are renovating, it is usually better to plan skylights early. This helps coordinate roof work, plastering, electrical work and painting.

Frequently Asked Questions
How much does it cost to install a skylight in Melbourne in 2026?
Most fully installed skylights in Melbourne cost between $2,500 and $6,500+. A sun tunnel may start from around $1,200 installed, while a premium solar opening skylight or flat roof skylight may cost more.
What is the cheapest skylight option?
A sun tunnel is usually the cheapest daylighting option. For a full glass skylight, a fixed VELUX skylight is usually the most affordable choice.
Is a fixed skylight cheaper than an opening skylight?
Yes. A fixed skylight is generally cheaper because it does not include an opening mechanism, motor, solar system or control switch.
Should I choose a manual or solar opening skylight?
Choose a manual opening skylight if the skylight is easy to reach. Choose a solar opening skylight if it is installed high above the floor, above a stairwell, or in a premium space where remote operation is more convenient.
Does skylight installation include plastering?
Not always. Some quotes only include roof work. A full-service quote should clearly state whether shaft framing, plasterboard, setting and sanding are included.
Is painting included?
Painting is often excluded unless specifically stated. Many skylight shafts are finished ready for painting, allowing the homeowner or painter to complete the final coat.
Can skylights be installed on flat roofs?
Yes, but flat roof skylights need the correct kerb, upstand, flashing and waterproofing detail. Flat roof installations usually cost more than simple pitched roof installations.
Can skylights be installed on tiled roofs?
Yes. Skylights can be installed on concrete or terracotta tiled roofs, but the installer must use suitable flashing and take care when cutting or handling tiles.
Can skylights be installed on Colorbond roofs?
Yes. Colorbond and metal roofs are common in Melbourne. The key is using correct flashing and sealing methods for the roof profile.
How long does installation take?
A standard skylight installation usually takes 1 to 2 days, depending on roof type, access, shaft depth, weather and plastering requirements.
Do skylights leak?
A properly installed skylight with the correct flashing should not leak. Most skylight leaks come from poor installation, incorrect flashing, roof movement, blocked drainage paths or old low-quality skylights.
Are VELUX skylights good for Melbourne weather?
Yes. VELUX skylights are a popular choice for Melbourne homes because they are designed for performance, daylight, ventilation and weather resistance when installed correctly with the correct flashing.
Can I add blinds later?
In many cases, yes. VELUX blinds can be added to improve light control, privacy and heat management. Solar-powered blinds are popular for hard-to-reach skylights.
Skylight Installation Costs Across Melbourne Suburbs
Costs can vary slightly depending on roof access, home age and roof type. Inner Melbourne homes in Richmond, Fitzroy, Carlton, Brunswick and South Melbourne often involve older roof structures, terrace homes, flat roof extensions or heritage considerations. Eastern suburbs such as Kew, Camberwell, Balwyn, Glen Iris and Hawthorn often have tiled roofs and established homes. Newer homes in Berwick, Clyde, Officer and surrounding south-eastern suburbs often have metal or Colorbond roofing, which may require different flashing details.
