Gable patio: the pitched roof patio explained, with 2026 prices
BeforeGable Roof PatioA gable patio has a pitched, triangle shaped roof that rises to a ridge in the middle, like the roof of a house. It suits homeowners who want a high, airy alfresco that looks like it was built with the home.
BeforeGable Roof PatioWhat is a gable patio made of?
Most gable patios use a steel frame: posts, a front beam, and steel trusses or rafters that form the pitch. Some are built in treated timber or a mix of steel and timber.
The roof is usually COLORBOND steel sheet, in a corrugated or ribbed profile such as TRIMDEK. Some owners choose insulated panels on the pitch for a cooler, finished ceiling.
The triangle at each end is called the gable. It can be left open, or filled with clear sheeting, battens, lattice or cladding.
A gable is often attached to the house with a flat link section between the house and the pitched part. On a single-storey home it can sit above the gutter line for extra height.
Pros and cons of a gable patio
Pros:
- High ceiling that feels open and spacious.
- Hot air rises into the peak, so it can feel cooler.
- Lets more light reach the house than a low flat roof.
- Strong street appeal; it can match a pitched house roof.
- Plenty of room for a fan and feature lighting.
Cons:
- Costs more than a flat or skillion roof.
- More complex frame, so it takes longer to build.
- A taller structure is more likely to need council approval.
- Gable infill adds cost if you want it closed in.
Who is a gable patio best for?
A gable suits homes with a pitched tiled or Colorbond roof, where a flat patio could look tacked on. It also suits Hamptons, federation and farmhouse style homes.
It works well for:
- Large alfresco areas used for entertaining.
- Yards where you want height and views, not a low ceiling.
- Hot climates, because the peak gives heat somewhere to go.
- Pool areas and outdoor kitchens that need good airflow.
If your eaves are low, a gable can lift above them so the patio does not feel cramped. Our double-storey house guide covers taller homes.

Popular gable options:

- Timber look or aluminium batten infill for privacy.
- Insulated roof panels on the pitch.
- Exposed rafters painted in a contrast colour.
- Ceiling fan and pendant or LED lighting.
- Outdoor blinds around the sides.
For tips on choosing the roof colour, read our Colorbond colours guide.
Do you need council approval for a gable patio?
Usually, yes. Gables are taller than flat patios, and height is one of the first things councils look at. Setbacks, site coverage and bushfire rating also matter.
Rules differ by state and council, so check before you sign. Our council approval guide for patios and pergolas explains the common paths.
Gable patio vs similar styles
Gable vs flat roof patio
A flat roof patio is cheaper and quicker. It sits lower, which suits single-storey homes with low eaves. Choose a gable when height, light and a built-in look matter more than budget.
Gable vs skillion patio
A skillion patio has one slope instead of two. It gives some of the height of a gable at a lower price, with a cleaner modern line. A gable looks more traditional and suits pitched house roofs.

Common questions
Is a gable patio better than a flat patio?
It is not better, it is different. A gable gives more height, a brighter feel and better airflow, and it often looks more like part of the house. A flat roof costs less and sits lower under eaves.
How much does a gable patio cost?
Our indicative installed price for a 6 m × 4.5 m gable roof patio is $16,000 to $18,500 in WA and $16,500 to $19,500 in Victoria, including GST. Height, infill, insulation and council fees move the final quote.
Can a gable patio be insulated?
Yes. The gable roof can use insulated panels instead of a single steel sheet, which keeps it cooler and gives a finished ceiling. It adds to the cost, so ask for both options in your quote.
What goes in the triangle end of a gable patio?
You can leave it open for airflow, or fill it with clear polycarbonate, battens, lattice or cladding. Clear infill keeps the light, while battens add privacy and a finished look.
