Single-skin versus insulated

A standard patio roof is single-skin Colorbond, which is one layer of steel on purlins. It keeps the rain off, but in a Brisbane summer it radiates heat straight down into the space underneath.

An insulated roof is a sandwich panel, with two steel skins and a foam core between them. It spans further without purlins, so the underside is a flat finished ceiling rather than exposed steel.

The underside of an insulated roof is a finished ceiling, with room for downlights and a fan.

What it changes

  • Heat. It's the main reason people choose it. In February a single-skin patio is somewhere you walk through. With the panel core it becomes an outdoor room you'll sit in.
  • Noise. A storm on single-skin steel is loud. The panel quietens it, which matters most when the patio sits directly outside a bedroom or living room.
  • A finished ceiling. Flat panel underneath instead of purlins and screw heads. Lights and fans mount into it cleanly.
  • Fewer posts. The panel spans further unsupported, so there's often one less post in the middle of the space. That matters most on a small patio.
  • When single-skin is enough. A patio over a driveway or a service area, or one that's shaded by the house most of the day, doesn't need it. We'll tell you if yours is one of them.

What's included

Design · engineering · council approval · construction · [6 years structural, 15 years on materials] warranty. Insulated panel is a roof material, so it can go on a flyover, gable or skillion.

How the whole process works

What moves the number

$12,500 is a custom insulated-roof patio, designed, approved and built. From there:

  • Size and span. The biggest driver on any patio.
  • Roof style. Skillion is the baseline; flyover and gable cost more to structure.
  • Panel thickness. A thicker core insulates better and costs more.
  • What it attaches to. A straightforward fascia connection is simple. A two-storey, a tiled roof or an awkward gutter line is not.
  • Ground conditions. Slope, fill, rock or reactive soil all mean more footing work.

You get a fixed price before you commit, and it stays fixed. The deposit is [5–10%], then progressive payments as the work goes up, so you only pay for what has been built.

Council and timeline

Most patios need approval. Mean height, boundary setback and any overlay decide it. Flyovers are taller, so council looks at them more closely than skillions.

500mm from a boundary with your neighbour's written agreement. Approval 2–6 weeks, build about 2 weeks, installation up to 10 weeks.

Common questions about insulated patios

Is an insulated patio roof worth the extra cost?

Yes, if you want to use the space through a Queensland summer. If the patio is shaded most of the day or covers a driveway, single-skin will do.

Can I add insulation to my existing patio?

Not as a lining, because the panel is the roof. You'd be re-roofing, and whether that's worth doing depends on the frame underneath. Send us a photo.

How much cooler is it?

Noticeably cooler. How much depends on which way it faces, the roof colour and how open the sides are. Customers who have both usually describe the single-skin one as somewhere they walk through.

What colours does it come in?

The standard Colorbond range, so it can be matched to your existing roof or gutters.
