How Much Does a Stratco Sunroof Cost in Melbourne?
A Stratco Sunroof sits at the premium end of the outdoor-living market, so one of the first questions homeowners usually ask is simple:
How much does it actually cost?
The answer depends on much more than just the size of the structure.
Attachment type, overall height, structural requirements, motor configuration, site access, drainage, electrical components, existing concrete and how the Sunroof integrates with the home can all affect the final installed price.
As an authorised Stratco dealer and registered builder servicing Melbourne’s south-east and the Mornington Peninsula, we quote Sunroof projects based on the actual property and design rather than relying on a fixed square-metre rate.
You can also explore our range of Stratco patios in Melbourne before comparing the different roof systems.
Even though every Sunroof is priced differently, a realistic price range can help you understand what budget you may need before requesting a detailed quote.
If you’re still learning how the opening louvre system works, our Stratco Sunroof Melbourne guide explains the product, operation and design options in more detail.
What Does a Stratco Sunroof Cost in Melbourne?
As a rough guide, a smaller Stratco Sunroof around 4.8 m × 2.0 m may sit around:
$20,000–$24,000 installed depending on the final design and site conditions.
Two Sunroofs with almost identical dimensions can still sit at different ends of that range.
One may be relatively straightforward, while another may require additional structural work, increased height, more difficult access, extra electrical components, a more complex drainage solution or a different attachment method.
For that reason, these figures should be treated as indicative qualifying prices rather than fixed quotes.
Why Two Similar-Sized Sunroofs Can Cost Different Amounts
A Sunroof is not priced purely by floor area.
Two structures with almost identical dimensions can still vary significantly in price because the design has to respond to the property.
Some of the main factors include:
overall dimensions
roof height
attachment type
structural beam requirements
column sizing
number of operating sections
number of motors
structural reinforcement
electrical components
drainage
site access
footings or concrete conditions
engineering and approvals.
This is why a simple square-metre rate can be misleading.
The size provides a useful starting point, but the final design determines the actual cost.
Does Attachment Type Affect Sunroof Cost?
Yes, although not always in the way homeowners expect.
Different attachment methods change the structural design, material requirements and amount of labour involved.
That means one attachment type is not automatically much cheaper than another.
Simple Attached Sunroof
A straightforward attached Sunroof can provide a useful baseline for pricing.
The structure connects back to the existing home, which can reduce some of the independent structural support required.
However, the existing building needs to be suitable for the proposed attachment, and connecting the Sunroof back to the house still requires structural detailing and installation labour.
The existing roofline, fascia, gutters, eaves and wall construction can all influence how the attachment is designed.
Three-Side Attached or Alcove Sunroof
A Sunroof installed into an alcove or attached on three sides can require:
additional structural beams
more detailed measurements
additional installation time
more work around existing walls and building lines
more complex structural detailing.
Because there can be more structural members and more labour involved, a three-side attached Sunroof may ultimately cost a similar amount to another configuration of comparable size.
It should not automatically be assumed that enclosing the Sunroof between existing walls will make the project cheaper.
Freestanding Sunroof
A freestanding Sunroof needs to support itself independently.
This generally means:
larger columns
independent structural support
different beam requirements.
However, if the structure can be bolted directly to a suitable existing concrete slab, the installation itself can be more straightforward because less work is required to attach the Sunroof back to the house.
For smaller projects, the final price can therefore be surprisingly close to an attached configuration.
For the type of projects we quote, a freestanding Sunroof over approximately 2.4 metres high, bolted to suitable existing concrete, may only add around $500-$1500 compared with a similar attached design.
The actual difference still depends on the structure and property.
If you’re comparing other patio roof styles and attachment options, see our Stratco Outback Patio Melbourne guide.
Why Larger Sunroofs Cost More
As the Sunroof becomes larger, the price does not simply increase at the same rate as the floor area.
At a certain point, the design itself can change.
For example, a Sunroof around 6.5 m × 3.9 m may need to be divided into two separate operating sections.
The overall width can mean one motor is no longer suitable for operating the entire roof.
The structure may therefore require:
two separate louvre sections
two motors
additional structural framing
a central structural member
additional control components
more complex installation.
A Sunroof of approximately this size and configuration may sit around:
$35,000–$45,000 installed depending on the final design, attachment method, height and site conditions.
This is why a larger Sunroof is not simply a larger version of a smaller structure.
The structural and mechanical requirements can change considerably.
What Other Factors Affect Stratco Sunroof Pricing?
Attachment type and overall size are only part of the calculation.
Overall Height
Height can have a significant effect on the structural design.
A taller Sunroof can influence:
column sizing
engineering
wind loading
structural reinforcement
access during installation.
Two structures with identical width and projection can therefore price differently if one needs to sit significantly higher.
Size and Span
Total floor area matters, but the shape of the structure can matter just as much.
A longer unsupported span may require:
larger beams
additional reinforcement
a different structural layout.
This is another reason why two Sunroofs with similar square metre areas can cost different amounts.
Structural Beams and Columns
The size and number of structural members can vary considerably between projects.
Factors such as:
attachment method
overall span
height
freestanding construction
three-side attachment
number of operating sections
can all affect the beam and column requirements.
Number of Motors and Operating Sections
Smaller Sunroofs may be able to operate as one section.
Larger structures may need to be divided into multiple operating sections.
Each additional section can require its own:
motor
framing
controls
structural support.
This can create a noticeable jump in price once the design reaches a certain size.
Existing Concrete
The existing ground conditions can make a significant difference.
If a suitable concrete slab already exists and the Sunroof can be bolted directly to it, installation can be considerably simpler.
If new footings are required, additional costs may include:
excavation
concrete
reinforcement
labour
spoil removal
access requirements.
The existing slab also needs to be suitable for the proposed structural loads.
Site Conditions and Access
Site access is another important factor.
A clear backyard with straightforward access is very different from a project where long structural components need to be carried through:
a narrow side passage
the house
established landscaping
restricted gates or openings.
Existing features can also affect installation, including:
pools
decking
retaining walls
landscaping
fences
existing patios
outdoor kitchens.
More difficult access generally means additional labour.
Drainage and Stormwater
A Sunroof still needs to manage rainwater correctly when the louvres are closed.
The location of the available stormwater discharge point can therefore influence the cost.
A nearby connection may be relatively straightforward.
If drainage needs to be extended through:
concrete
paving
landscaping
decking
the additional work can increase the project cost.
Electrical Components
Electrical requirements can also make a noticeable difference to the final price.
Depending on the project, electrical components may include:
integrated louvre lighting
additional downlights
power points
ceiling fans
outdoor heaters
switches
control systems.
These requirements are best considered during the original design rather than added after the structure has been ordered.
Existing House Conditions
Attached Sunroofs have to work with the existing home.
The design can be influenced by:
fascia condition
gutters
eaves
roof structure
wall positions
windows
doors
existing downpipes.
Sometimes a design that looks simple on a plan becomes more complicated once the existing building is inspected.
This is why a proper site assessment is important before finalising the quote.
Engineering and Approvals
Depending on the property, additional requirements may include:
engineering
building permit
Report and Consent
Build Over Easement approval
planning advice
planning approval
developer approval.
Not every project requires every approval.
However, these requirements should be identified as early as possible because they can affect both the design and the overall project budget.

If the proposed Sunroof sits close to a side or rear boundary, see our guide to building a patio close to the boundary.
What Is a Realistic Budget for a Smaller Stratco Sunroof?
For a smaller Sunroof around 4.8 m × 2.0 m, a realistic starting budget may be around:
$20,000–$24,000 installed
One project may sit toward the lower end of that range, while another of almost identical size may sit toward the higher end.
The difference can come from things such as:
attachment method
overall height
structural beam requirements
column sizes
site access
drainage
electrical inclusions
concrete or footing requirements
engineering and approvals.
The important point is that the dimensions alone do not determine the final price.
What Is a Realistic Budget for a Larger Stratco Sunroof?
For a larger Sunroof around 6.5 m × 3.9 m, particularly where the roof needs to be divided into two operating sections, a realistic guide may be around:
$35,000–$45,000 installed
The higher price reflects more than just the additional floor area.
The design may also require:
two motors
two louvre operating sections
additional structural beams
a central structural member
additional controls
larger columns
greater installation complexity.
The final figure still depends on the individual property and design.
Why We Don’t Publish a Fixed Square-Metre Rate
It can be tempting to price a Sunroof using a simple dollar-per-square-metre calculation.
The problem is that this can create the wrong expectation.
Two Sunroofs with almost identical floor areas might have:
different heights
different spans
different attachment methods
different beam layouts
different motor configurations
different electrical packages
different drainage requirements
different access conditions.
Even though the overall floor area is similar, the amount of material and work involved can be quite different.
For that reason, we prefer to provide indicative project ranges rather than a fixed square-metre price.
The final price should always come from a site-specific design.
Is a Stratco Sunroof Worth the Extra Cost?
That depends on what you want from your outdoor space.
A fixed-roof patio such as an Outback Flat or Cooldek can provide excellent permanent weather protection and may be more cost-effective.
If you’re weighing up fixed-roof options, our Cooldek vs Outback Flat Patio guide explains the differences in more detail.
A Sunroof provides something different:
control over the outdoor environment.
When conditions suit, you can open the louvres to allow:
sunlight
airflow
an open-air feeling.
When you want greater protection, the louvres can be closed to provide:
shade
rain protection
a more enclosed outdoor area.
This flexibility can be particularly valuable where a patio sits outside:
living rooms
dining areas
kitchens
large sliding doors
stacker doors.
A fixed roof can sometimes reduce natural light entering these areas.
An opening louvre system gives the homeowner much greater control.
If you are still deciding whether an opening louvre roof is right for your home, our
Stratco Sunroof Melbourne guide explains how the system works in more detail.
Sunroof vs Cooldek
Another common question is whether to choose a Stratco Sunroof or Cooldek.
They solve different problems.
Cooldek provides:
permanent insulated roofing
consistent shade
thermal performance
a finished ceiling appearance.
Sunroof provides:
adjustable sunlight
adjustable ventilation
an opening roof
greater control over the outdoor environment.
The better option depends on what matters most to you.
If your priority is permanent shade and insulation, Cooldek may make more sense.
If controlling sunlight and airflow is more important, Sunroof may be worth considering.
We will cover this comparison in more detail in our separate Stratco Sunroof vs Cooldek guide.
What We Check Before Proposing a Stratco Sunroof
Before finalising a Sunroof price, we look at much more than just the width and projection.
We typically assess:
available outdoor space
attachment points
existing roof structure
proposed height
overall span
slab suitability
footing requirements
boundaries
easements
drainage
stormwater discharge points
site access
electrical requirements
natural light
windows and doors
likely approvals
how the area will actually be used.
This allows the Sunroof to be designed around the property rather than relying on a generic configuration.
If you’re comparing installers, our guide to choosing a Stratco patio builder in Melbourne covers the key questions worth asking before you commit.
Frequently Asked Questions
How much does a Stratco Sunroof cost in Melbourne?
As a rough guide, a smaller Stratco Sunroof around 4.8 m × 2.0 m may sit around $20,000–$24,000 installed, depending on the final design and site conditions.
Larger structures can cost considerably more.
How much does a large Stratco Sunroof cost?
A larger Sunroof around 6.5 m × 3.9 m, particularly where two operating sections and two motors are required, may sit around $35,000–$45,000 installed.
The final price depends on the attachment method, height, structure, electrical requirements, drainage and site conditions.
Why can two Sunroofs of the same size cost different amounts?
Two similarly sized Sunroofs can have different:
heights
attachment methods
beam requirements
column sizes
motor configurations
electrical inclusions
drainage requirements
access conditions.
These differences can move one project toward the lower end of the price range and another toward the higher end.
Is a freestanding Sunroof more expensive?
Not necessarily by a large amount.
A freestanding Sunroof requires larger columns and independent structural support, but if it can be bolted directly to a suitable concrete slab, installation can be simpler.
For smaller projects, the difference may only be modest.
Does an alcove Sunroof cost more?
An alcove or three-side attached Sunroof can require more structural beams and more labour.
As a result, the finished price can end up similar to other attachment configurations rather than automatically being cheaper.
Does height affect Sunroof pricing?
Yes.
Greater height can affect:
column sizing
engineering
wind loading
structural requirements
installation access.
Do larger Sunroofs need more than one motor?
They can.
Once the width becomes too large for a single operating section, the Sunroof may need to be divided into multiple louvre sections with separate motors.
This increases both the structural and mechanical requirements.
Are lights available in a Stratco Sunroof?
Yes.
Lighting can be incorporated into the design, but the number of lights and electrical requirements will affect the final price.
Do Stratco Sunroofs need a building permit in Victoria?
Many Sunroof projects will require a building permit.
Depending on the property, other approvals may also need to be considered.
For more information, see our patio building permit Victoria guide.
Planning a Stratco Sunroof?
If you are considering a Stratco Sunroof, the best place to start is with the property itself.
We can assess:
the available area
attachment options
preferred height
structural requirements
existing concrete
drainage
electrical requirements
likely approvals
budget.
From there, we can recommend a Sunroof configuration that suits both the property and the way you want to use the space.
More room, more moments.
