How to Choose the Right Skylight for Your Home
The best skylight is not simply the biggest or most expensive one. It is the model, size and position that suit your room, roof, daylight needs, ventilation goals and budget.
- ✓ Fixed, manual, solar and electric options
- ✓ Pitched and flat roof solutions
- ✓ Melbourne-specific installation advice
Which skylight type sounds most like you?
Use this as a starting point. The final choice should still account for your roof structure, ceiling cavity and the position of the room.
Fixed skylight
Choose this when your main goal is more natural light and the room already has adequate ventilation.
Explore fixed skylights →Opening skylight
Best for bathrooms, kitchens, laundries and rooms where releasing steam or warm air is important.
Explore manual opening →Solar or electric
Ideal for high ceilings, hard-to-reach positions and homeowners who want remote operation.
Explore solar skylights →Sun tunnel
A practical choice for hallways, walk-in robes, toilets and internal rooms with limited roof space.
Explore sun tunnels →Choose the skylight in the right order
Homeowners often begin with a product model. A more reliable approach is to start with the room and work upward to the roof.
Start with the room
Think about the room’s size, current windows, ceiling height and how the space is used. A large open-plan living area usually benefits from a full VELUX skylight or a group of skylights. A narrow hallway may only need a sun tunnel.
- ✓Identify where daylight is weakest.
- ✓Decide whether you want a subtle improvement or a major architectural feature.
Decide whether ventilation matters
A fixed skylight brings in daylight but does not open. An opening skylight can release heat, steam and indoor moisture. This is especially useful in bathrooms, kitchens and rooms with high ceilings.
Check the roof type
The roof determines which skylight family and flashing system can be used. Tile, corrugated metal, Trimdek, Kliplok, pitched and low-pitch roofs each require an appropriate installation approach.
Select the size and position
Bigger is not automatically better. The result depends on the room proportions, roof framing, direction of sunlight and the shape of the internal light shaft.
- ✓East-facing positions favour morning light.
- ✓North and west can provide stronger light and heat.
- ✓South-facing positions can provide softer, more even daylight.
Choose the correct flashing
The skylight and flashing must work as one roof system. Correct water flow, back flashing, side drainage and roof-profile detailing are essential parts of a dependable installation.
Compare the complete installed result
Consider the skylight, roof work, structural framing, light shaft, plaster finishing, roof access and any optional blind or control system—not only the product price.
Fixed, manual, solar or electric?
All four can provide excellent daylight. The main difference is how much ventilation and operating convenience you want.
Fixed
A simple daylight solution with no opening mechanism.
- ✓Usually the most economical full skylight option
- ✓Excellent for living rooms, halls and bedrooms
- ✓Suitable when other ventilation is already available
Manual opening
Natural light and ventilation with manual operation.
- ✓Good for bathrooms, kitchens and laundries
- ✓Useful where the skylight is reachable or operable by rod
- ✓Lower complexity than powered models
Solar opening
Remote-controlled ventilation without needing a mains power cable to the skylight.
- ✓Convenient for high or hard-to-reach ceilings
- ✓Popular in bathrooms, kitchens and premium renovations
- ✓A strong balance of comfort and installation flexibility
Electric opening
Powered operation for projects where electrical control is preferred.
- ✓Suitable for high-end renovations and integrated electrical plans
- ✓Remote convenience for inaccessible positions
- ✓Best considered early in a build or renovation
Match the solution to the space
These are practical starting points, not rigid rules. Roof framing and ceiling conditions can change the best option.
Living and dining areas
Usually suit one large fixed skylight or a balanced group of skylights for a stronger architectural effect.
Bathrooms
An opening skylight can provide daylight and help release steam and warm, humid air.
Kitchens
Fixed models work well for light; opening models add useful high-level ventilation over busy cooking areas.
Bedrooms
Fixed, manual or solar models can work. Consider light control, privacy, orientation and an optional blind.
Hallways and stairwells
A fixed skylight creates a strong vertical light source. A sun tunnel may suit narrow or obstructed spaces.
Walk-in robes and toilets
Sun tunnels are often the most practical way to brighten small internal rooms without using a full window-sized opening.
Your roof matters as much as the room
The correct product, pitch range and flashing arrangement must suit the roof—not be forced to fit it.
Pitched roofs
VELUX FS, VS, VSS and VSE skylights are commonly used on pitched roofs. The exact flashing depends on whether the roof is tiled, corrugated metal or another profile.
Roof pitch, rafter spacing, shaft position and external drainage all influence the final model and location.
Flat and low-pitch roofs
Flat-roof VELUX models such as FCM, VCM and VCS require an installation method designed for lower roof pitches. A raised kerb or custom flashing arrangement may be needed to support drainage and waterproofing.
Custom Colorbond flashing may be required for corrugated, Trimdek, Kliplok and other Melbourne roof profiles.
More glass does not always mean better light
A skylight that is too small may have little impact. One that is too large or badly positioned may create unwanted glare or heat.
A professional assessment should consider:
- ✓Room dimensions and ceiling height
- ✓Roof pitch, roof profile and available roof area
- ✓Rafters, trusses, ducts, pipes and electrical services
- ✓Direction of sunlight and likely summer heat
- ✓Light shaft width, flare and internal finish
- ✓Whether a blind or ventilation model is useful
Still deciding between two options?
That is exactly what a measure and quote is for. We can assess the room, ceiling and roof, then explain the practical differences before you commit to a model.
Compare complete solutions—not just skylight prices
The final cost depends on the model, size, roof access, flashing, structural work, ceiling type, shaft construction and internal plaster finishing.
Most economical
Sun tunnels for smaller internal spaces and fixed skylights where ventilation is not required.
Mid-range flexibility
Manual opening skylights add ventilation without the extra controls of a powered system.
Premium convenience
Solar and electric opening models are suited to high ceilings, remote operation and comfort-focused renovations.
A skylight is more than a window in the roof
The finished result depends on product selection, roof work, waterproofing, framing, the light shaft and the quality of the internal finish.
Roof-specific advice
Recommendations based on the roof pitch, material, profile, water flow and site access—not a one-size-fits-all package.
Complete installation
Roof cutting, framing, flashing, waterproofing, shaft construction and plaster finishing can be included in the installation scope.

Choosing a skylight: common questions
Is a fixed or opening skylight better?
A fixed skylight is usually the better-value choice when daylight is the main goal. Choose an opening model when the room would benefit from high-level ventilation, particularly in bathrooms, kitchens and humid spaces.
What is the best skylight for a hallway?
A sun tunnel is often suitable for a narrow hallway or a location with limited roof space. A fixed skylight can create a stronger architectural result where there is enough roof and ceiling space for a full light shaft.
Can a VELUX skylight be installed on a metal roof?
Yes, provided the skylight and flashing arrangement suit the roof pitch and metal profile. Corrugated, Trimdek and Kliplok roofs can require different custom flashing details.
What skylight suits a flat roof?
VELUX flat-roof models such as FCM, VCM and VCS are designed for low-pitch applications. The installation may also require a suitable kerb, upstand or custom flashing system to support drainage.
How many skylights should I install?
That depends on the room size, ceiling height, roof structure and the effect you want. In a large open-plan room, two or three smaller skylights can sometimes distribute daylight more evenly than one very large skylight.
Do I need to know the model before requesting a quote?
No. Photos or a home visit can help identify the roof, ceiling and room conditions first. The suitable model, size, flashing and position can then be discussed with you.
