Flat Roof Patios
Flat Roof Patios Done Properly
A flat roof patio, sometimes called a skillion, runs on a single gentle slope away from the house so rainwater drains cleanly to one side.
It is the most popular patio style we build across Joondalup and the northern suburbs because it is affordable, quick to install and works with modern and older homes alike.
We build every flat roof patio in Colorbond steel or insulated Solarspan panels, engineered for Perth conditions and finished to match your home.
Whether you are extending a main entertaining area at the back or adding a covered side entry, a flat roof patio delivers maximum covered space for the budget.
Cost effective
The simplest roof structure to build, which keeps the price down without cutting corners on quality.
Suits any home
A low, clean profile that blends with modern and traditional Perth rooflines.
Great drainage
The single slope sheds Perth's winter downpours quickly to a single gutter line.
Insulation ready
Upgrade to Solarspan panels for a cooler, quieter space you can use all summer.
Fast to build
A straightforward structure means shorter on-site time and less disruption to the household.
Colour matched
Colorbond's full palette means the roof, posts and gutter can match or complement your home's existing colours exactly.

What a Flat Roof Patio Is
A flat roof patio is built on a slight fall, attached to your fascia at the high side and sloping gently to the outer beam. That fall moves rainwater off the roof into a single gutter so you never get pooling.
Colorbond or Solarspan?
Colorbond is the budget-friendly single-skin sheet. Solarspan is an insulated sandwich panel with a finished ceiling underneath, which keeps the space cooler in summer and quieter in the rain.
| Feature | Colorbond | Solarspan Insulated |
|---|---|---|
| Starting cost | Lower | Higher |
| Summer heat | Radiates heat in | Blocks radiant heat |
| Rain noise | Loud | Very quiet |
| Ceiling finish | Exposed framing | Smooth white ceiling |
| Best for | Budget, good orientation | Year-round comfort |

An unpermitted patio can create significant issues when you sell your property and may need to be removed at your own cost. We always apply for the correct approvals before starting any work.
FAQs
Flat Roof Patios FAQs
Cost depends on the size, the roof material and the site, but a flat roof patio is generally the most affordable style because the structure is simple. We give a fixed written quote after measuring, so there are no surprises.
Most patios in the City of Joondalup need a building permit. We handle the drawings, engineering and application for you as part of the job, so you do not need to deal with the council process yourself.
Colorbond is the cost-effective single-skin option. Solarspan is insulated with a finished ceiling underneath, so it stays noticeably cooler in summer and quieter in the rain. We help you weigh up both options for your specific space and orientation.
Most flat roof patios are installed in one to three days on site once approvals are through. The approval process is typically the longest part of the timeline. We give you a realistic timeframe at quote stage.
The full Colorbond range is available, from light neutrals through to dark charcoals. We help you select a shade that either matches your existing roof or creates a deliberate contrast that suits the home. Sample cards are on every visit.
Yes. While most flat roof patios are attached to the house fascia, we can design and engineer a freestanding structure if that suits your block or preferred layout.
If you choose Solarspan insulated panels, the smooth finished ceiling is ideal for ceiling fans and recessed downlights wired by a licensed electrician. Standard Colorbond exposes the framing underneath, which limits lighting options unless you add a separate ceiling lining.
