DIY Versus Custom Built


A DIY carport might seem to be good value for money. However, these cannot be assembled by one person. It can also be very time consuming. It can also be difficult to choose exactly what to buy, but by hiring a professional carport builder you can listen to their advice.

Having your patio or carport built by a professional also makes it much more flexible. Should you ever want to convert the structure into a study then this will be easier with a custom built design.

Both carports and patios or even pergolas built by professional builders are built to last. Most will come with guarantees to ensure that you are protected from poor workmanship.

Carport & Patio Roof Materials

Roofing Materials

There are many different roofing materials which can be used for renovations. This section will overview the popular types and look at the benefits and problems associated with each material. Common roofing materials for carports include:

  • Colorbond Steel
  • Zincalume
  • Aluminum
  • Tile
  • Polycarbonate


Carports and Patios can either have gable roofs, or flat roofs. Each roofing material is suitable for a different type of roof.

Colorbond Steel

Colorbond is a type of steel roofing which is available in 22 different colors. This makes it possible to blend the design of the carport or patio in with the rest of the house. Colorbond is designed to withstand Australian weather.


  • Long lasting
  • Highly Durable coating – Tested to last over 45 years
  • Designed to withstand Australian weather
  • Low maintenance
  • Cheaper than roof tiles



  • Any damage to the coating can cause the metal to corrode
  • May need to be re-coated every 10 years or so
  • Noisier than tiled roof


Colorbond costs around AU$35 per square meter. This makes it slightly more expensive than other types of roofing, but it does have lots of advantages.


Zincalume is a type of sheet metal roofing manufactured by Bluescope steel. This has a durable and hard wearing coating which will protect the steel.


  • Longer lasting than galvanized steel
  • Durable
  • Can be painted the color you want
  • Easy to clean



  • Zincalume will need to be repainted regularly
  • Can corrode if coating is scratched or damaged


Zinculume is slightly cheaper than colorbond, and typically comes in at around AU$32 per square meter. However, bear in mind that it will require painting to blend in with the house.

If using coated steel it’s important you choose a builder who is familiar with the material. If it is fixed with screws then this can cause damage to the coating which could cause the metal to rust and corrode.


Aluminum is one of the best materials for roofing because it is corrosion resistant. The sheets of aluminum normally interlock to provide a highly durable roofing material.


  • Highly durable roofing material
  • Lightweight
  • Aluminum can be cut to size without additional treatment
  • Corrosion resistant
  • Recyclable building material
  • Can be coated in many different finishes and colors



  • More expensive than other types of roofing
  • Quite noisy roofing material
  • Not all installers experienced with aluminum
  • Aluminum is quite soft and can become dented easily


Aluminum roofing is the most expensive metal roof option. This typically costs around $50 per square meter. However, it will require virtually no maintenance and will last for a very long time.


A tiled roof is most suitable for gable style roofing. It’s the most traditional form of roofing and very long lasting.


  • Matches the roofing of traditional homes
  • Very durable
  • Virtually maintenance free



  • More difficult to install
  • Costly roofing option
  • Damage to individual tiles can cause leaks


The cost of tiling a roof will depend on the shingles you choose to use. Concrete tiling can cost around $30 per square meter, with terracotta tiles being around $40 per m2. Slate tiles are the most expensive option and come to around $300 per square meter. There will also be installation costs on top of this.


Polycarbonate is a very tough roofing material. This can be purchased in both transparent and opaque versions.


  • Available in transparent styles
  • Opaque and tinted versions available
  • Very long lasting
  • Lighter and stronger than glass
  • Resistant to sunlight



  • Although strong it can scratch
  • Cannot be cleaned using acidic cleaners
  • Not environmentally friendly
  • Not available in as many colors


Polycarbonate is fairly expensive, but it is very long lasting. It is also fully waterproof and won’t require any maintenance. The only concern that some people might have is that it’s not environmentally friendly.
