A pergola is one of the most popular outdoor additions in Australian homes. It creates a shaded place to relax, entertain, and enjoy the outdoors year-round. But choosing the right roofing material for your pergola is just as important as the structure itself.
Two of the most common options are steel roofing and polycarbonate roofing. Both are widely used, both are durable, and both suit Australian conditions. However, they offer very different outcomes in terms of light, comfort, appearance, and how you use the space.
At Roofing Options, we help homeowners, builders, and trades choose pergola roofing that works for their lifestyle, not just their structure. In this guide, we break down steel vs polycarbonate pergola roofing, explain the pros and cons of each, and help you decide which option is best for your project.
Why Your Pergola Roof Choice Matters
A pergola roof does more than provide shade. It directly affects:
- How much light enters the space
- How hot or cool the area feels
- How often you can use the pergola
- The overall look of your outdoor area
- Long-term maintenance and durability
Choosing the wrong material can leave a pergola feeling dark, too hot, or underused. Choosing the right one can turn it into one of the most lived-in spaces in your home.
Steel Pergola Roofing
Steel roofing is a popular choice for pergolas, especially where full shade and durability are priorities.
At Roofing Options, we supply steel roofing sheets made from high-quality materials designed for Australian conditions. These are commonly used in patios, pergolas, verandahs, and carports.
Key features of steel roofing
- Made from COLORBOND or ZINCALUME steel
- Strong and weather resistant
- Provides full shade and protection
- Long lifespan with minimal maintenance
Steel pergola roofing is particularly popular in areas that experience strong sun, heavy rain, or unpredictable weather.

Polycarbonate Pergola Roofing
Polycarbonate roofing is a lightweight, translucent option that allows natural light through while still offering protection from the elements.
At Roofing Options, we stock a wide range of polycarbonate roofing sheets and systems, including Laserlite, Ampelite, Sunsky, Suntuf, and Sunlite Twinwall.
Key features of polycarbonate roofing
- Allows natural daylight into the space
- Lightweight and impact resistant
- Available in clear, tinted, and opal finishes
- Designed to handle Australian UV conditions
Polycarbonate pergola roofs are especially popular for outdoor areas connected to living spaces, where light and openness are important.
Light and Shade: How Much Sun Do You Want?
One of the biggest differences between steel and polycarbonate pergola roofing is how they handle light.
Steel roofing and light
Steel roofing provides full shade. It blocks sunlight completely, which can be a major advantage in hot climates.
Steel is ideal if:
- You want a cool, shaded outdoor area
- Your pergola faces direct afternoon sun
- You plan to use the space during summer
However, because steel blocks light, the area underneath can feel darker, particularly if the pergola is attached to the house.
Polycarbonate roofing and light
Polycarbonate allows natural light to filter through, helping pergolas feel bright and open.
Depending on the product, you can choose:
- Clear sheets for maximum daylight
- Tinted or opal sheets to reduce glare and heat
- Heat-reducing options designed for comfort
If letting light into your pergola and adjacent indoor spaces is important, polycarbonate is often the better choice. Our blog on top roofing ideas to let in the daylight explores this concept in more detail.
Heat and Comfort in Australian Conditions
Australian weather can be harsh, so pergola comfort matters.
Steel pergola roofs
Steel roofing reflects heat well and provides consistent shade. This can make pergolas significantly cooler during hot days, especially when combined with good airflow.
However, because steel blocks all light, it may also block winter warmth, which can make the space feel cooler in colder months.
Polycarbonate pergola roofs
Modern polycarbonate roofing is designed to manage heat more effectively than older materials.
Many polycarbonate options:
- Filter UV rays
- Reduce heat build-up
- Allow light without excessive glare
Products such as heat-control polycarbonate sheets are designed specifically for outdoor living areas where comfort is key.
The right polycarbonate selection and correct installation are essential. Thermal movement needs to be allowed for, which we cover in our guide on thermal expansion and polycarbonate roofing.
Noise and Weather Performance
Rain noise is another factor many homeowners consider.
Steel roofing noise
Steel roofing can be noisier during heavy rain. While some people enjoy the sound, others may find it disruptive during entertaining or relaxing.
Polycarbonate roofing noise
Polycarbonate generally produces less rain noise, particularly multiwall systems such as Sunlite Twinwall, which help dampen sound.
If your pergola is used frequently for dining or entertaining, noise levels may influence your decision.
Appearance and Design Flexibility
Pergolas are often a visual feature of the home, so appearance matters.
Steel roofing appearance
Steel roofing creates a clean, solid look that works well with:
- Modern homes
- Industrial or minimalist designs
- Pergolas designed as extensions of the house roof
Steel is available in a wide range of colours, allowing it to blend seamlessly with existing roofing.
Polycarbonate roofing appearance
Polycarbonate offers more visual flexibility. It creates a lighter, more open feel and works well in:
- Garden pergolas
- Courtyard spaces
- Outdoor areas connected to living rooms
Options such as Sunlite Twinwall provide a sleek, contemporary finish while improving insulation and comfort. Our Sunlite Twinwall installation guide and tips is a useful resource if you are considering this system.
Durability and Maintenance
Both materials are durable, but they age differently.
Steel roofing longevity
Steel roofing is known for its long lifespan and low maintenance. When installed correctly, it can last for decades with minimal upkeep.
Polycarbonate roofing longevity
High-quality polycarbonate is extremely impact resistant and designed to handle Australian UV exposure. Over time, cheaper products may discolour, which is why selecting trusted brands is important.
At Roofing Options, we stock polycarbonate roofing designed for long-term performance, helping reduce maintenance and replacement concerns.
Cost Considerations: Upfront vs Long-Term Value
Steel roofing costs
Steel roofing is often more affordable upfront, particularly for larger pergola structures. It also offers excellent long-term value due to its durability.
Polycarbonate roofing costs
Polycarbonate roofing can cost more initially, depending on the product and finish. However, it may deliver better lifestyle value by creating a brighter, more inviting space.
Choosing between steel and polycarbonate often comes down to how you plan to use the pergola rather than cost alone.
Which Pergola Roof Is Right for You?
Steel pergola roofing may suit you if:
- You want full shade and maximum weather protection
- Your pergola faces strong sun
- You prefer a solid, roof-like structure
- Low maintenance is a priority
Polycarbonate pergola roofing may suit you if:
- You want natural light without full exposure
- Your pergola connects to indoor living areas
- You prefer a lighter, more open feel
- You want flexibility in light and heat control
Many homeowners also choose a combination of materials to balance light and shade across different areas of the pergola.
