Is Colorbond or polycarbonate better for a patio in WA?

It depends on what you want from the space. Colorbond steel gives a cooler, shaded, private patio that stands up to WA's sun and weather, and it can be insulated for even better heat and noise control — ideal for year-round entertaining. Polycarbonate is translucent, so it lets daylight through and is great for brightening a shaded courtyard or lean-to, usually at a lower upfront cost. Both are available on our WA engineered patio kits.

Does a Colorbond patio keep you cooler than polycarbonate?

Generally yes. A solid Colorbond roof blocks direct sun and radiant heat, so the space underneath stays cooler and shaded. An insulated Colorbond roof (such as Solarspan) improves this further by reducing heat transfer. Polycarbonate lets light — and some heat — pass through, so the area underneath can feel warmer in full sun, which is sometimes desirable in winter-use areas.

Is polycarbonate roofing noisy in the rain?

Polycarbonate tends to be louder than steel in heavy rain. A standard Colorbond roof has a soft drumming sound, and an insulated Colorbond roof is quieter again thanks to the foam core. If a quiet, all-weather entertaining area matters to you, Colorbond — particularly insulated — is usually the better choice.

Which roofing is more durable?

Colorbond steel is extremely durable and is manufactured for Australian conditions, resisting fading, peeling and corrosion for decades. Polycarbonate is durable for its weight but can yellow or become brittle over many years of UV exposure, depending on grade. For a long-life patio in WA's harsh sun, Colorbond is the more robust option.

Are Colorbond and polycarbonate patio kits engineer certified?

Documentation and engineering, if supplied, are project-specific and depend on the selected roof configuration, site and approval pathway. They are not a permit and do not guarantee approval. Assembly must follow the supplied project documents; use our patio calculator for an instant estimate or preview colours with Design It On My House.
