Can you imagine a home without a roof? While the idea seems unique, a house can never be complete without sturdy roofing materials protecting those who live in it. The top is like a security blanket that keeps us safe from the harsh weather and other elements. “It’s also an investment material and an essential part of the home because it can withstand the test of time, winds, extreme heat, heavy rains, and even storms. Aesthetically speaking, the roofing is the crown of the house, so it’s ideal to consider the type and colour that will match the structure and design as a secondary consideration.
Colorbond roof cost per square meter varies from $53 to $97 for new residential homes, including materials and installation. Having a professional roofing contractor to perform the installation is always recommended. You need a sturdy roof that protects your house from structural damage. Colorbond roof installers charge based on your roof’s size and other factors that affect the cost of installation.
Re-roofing your home, as the name suggests, involves replacing your roof, either because it’s past its use-by date or for aesthetic purposes. This is done by putting a new one over the old one (a not common practice) or removing the old one and replacing it with new (recommended). If you’re on a tight budget, $12,000 is usually the minimum starting mark. Looking for a roof replacement? Check out Top Glaze for a wide range of roof services.

To help you understand more about Colorbond roofing, we provide the following ten quick tips below to help you make an informed decision.
CONSIDER YOUR BUILDING PLANS
Before you begin to think about choosing Colorbond roofing, you must consider how you want your new roof to look. Remember, your new roof will need to blend in with the property’s exterior and comply with any regulations, property title requirements and local council regulations. For example, you might have to install a roof with a particular pitch elevation, or there might be a restrictive covenant requiring your roof to have a tiled look.
Here are a few things you should consider:
- How will your new roof look compare to the exterior design and landscaping of the property?
- Are you replacing your roof, and are you limited by internal structural restrictions?
- Do you want a pitched roof, flat roof or an inverted pitched roof?
- Will your new roof design be practical and easy to maintain?
- Are there any restrictive covenants or heritage overlays affecting your title?
- Are there any local council restrictions or plumbing regulations that you need to comply with?
- Have you consulted a licenced plumber?
CONSULT A LICENCED MELBOURNE PLUMBER
You must consult a licenced plumber when you are considering the roofing of your property. A licenced plumber should install a roof, so it is best to have the plumber involved in planning discussions. Ensure the plumber is a part of all discussions with other tradespeople so that communications are fluid and all decisions have been transparently reached.

It is important to remember that your roof will keep you safe and secure from the outdoor environment for many years. Do not compromise on the roofing material and ensure that you invest in a quality roofing system such as Colorbond roofing.
GUTTERS, FASCIA AND DOWNPIPES
Alongside your new Colorbond roof, you will also need to consider gutters, fascia and downpipes. This is all part of the roofing system because runoff water will need to pass through gutters and downpipes and flow into underground drains. Your plumber will help you design the entire roofing system. Make sure you also consider the design and colour of your gutters, fascia and downpipes so that it suits your property’s exterior and new roof.
While the installation of your new roof will have a warranty given from the licenced plumber in accordance with plumbing regulations, the manufacture of the roof can also be guaranteed (i.e. against peeling, cracking, corrosion, etc.). BlueScope does provide warranties for its steel roofing system. You can discuss suitable warranty options with your builder or plumber. If you are project managing the build yourself, make sure you have these discussions with your sales representative and ensure that you choose an appropriate warranty to suit your needs and requirements.
COST TO INSTALL COLORBOND® ROOFING
In addition to the cost of Colorbond roofing, you will also need to consider the installation cost. Seek quotations and estimated from licenced plumbing professions.
Your Colorbond roof must be installed by a licenced and professional plumber. In addition to the roofing, the associated parts such as the gutter, fascia and downpipes must also be installed by a plumber who will follow the appropriate and applicable plumbing regulations. Following installation and a satisfactory building inspection and another testing (as required), your plumber will issue you with a plumbing certificate which will note the jobs that it has completed for your build. Among other installations and servicing, the roofing system installation will be noted. Keep this handy on file for future reference.
How to Install Colorbond Roof: Step by Step
Installing Colorbond roofing on the house, shed, or patio can be a DIY project, but it’s not a project for an unskilled do-it-yourselfer.
It’s essential that the roof is installed in line with Australian Standard AS 1562 – ‘Design and installation of metal roofing’. This is to ensure the roofing is installed correctly and won’t pose a danger in normal or extreme weather conditions.
Colorbond roof installation has six basic steps:
Step 1: Install gutters, fascias and battens
Guttering and fascias should be installed first, which can be chosen to match your Colorbond roofing. You should then lay the battens on the trusses to support the roof.
Step 2: Install sarking or roof blankets
Sarking (reflective foil laminate) or a foil-backed roof blanket should be laid before placing the roof sheets. This helps to insulate the roof and prevent rot and rust.
Step 3: Lay the Colorbond roof sheets.
Install Colorbond roof sheets by lapping the sheets against the prevailing wind direction. If your roof has hips and valleys, these should be marked on the sheets and carefully cut using a power saw or metal shears.
Step 4: Attach the roofing.
Check that the roof sheets are correctly aligned at the gutter end, then fasten the roof in place. This may involve drilling or using the provided fixings.
Step 5: Install cappings
When the roofing is secured, bend the valleys upwards and install cappings across the roof ridge, hips and fascias.
Step 6: Clean the roof
Carefully clean the roof using a broom or leaf blower to remove swarf. These tiny fragments of metal can cause a roof to quickly corrode if they are not removed.
