When your Concrete Tile, Terracotta Tile or metal roof is beyond repair it may be time for a roof replacement. At some point the original roof on a house may have run its usable life and be beyond the point of roof restoration. The original concrete or Terracotta roof tiles may have become brittle or started fretting or the original metal roof may be showing signs of rust. When a roof reaches this point it’s best to stop spending good money on short term fixes and invest a little more in the appearance and performance of your roof by undertaking a full roof replacement.


The ultimate and best type of roof replacement is a Tile to Iron or (Colourbond) roof replacement. This type of roof replacement is becoming more common all over Adelaide as the original tiled roofs on many older houses reach the end of their serviceable life.  Roof replacement can be a great value option especially when viewed over the longer term. The warranty terms and piece of mind that come with a roof replacement make it great investment for many homes.

The Benefits of Roof Replacement

The benefits of undertaking a roof replacement on an original tiled roof with Colourbond are many especially when viewed over many years. Other than the obvious points of increased property value and peace of mind of a 15 year leak free warranty the key benefits are:

Roof Insulation

The original tiled roof on a house carries a lot of thermal mass, meaning it can stay warm in summer for many hours after the sun has gone down. Tiled roofs also give very little insulative benefits to the roof space. When we carry out a tile to iron roof replacement, we highly recommend our clients to pay a little extra and have an roof Insulation blanket lining the new roof sheeting. The 60mm foil backed glasswool Insulation blanket makes a huge difference to heat transference in both summer and winter. With the product being installed directly against the inside surface of the roof sheeting it is highly efficient at blocking out the heat before it enters the roof space. Its installation is quite neat on an original tiled roof as the foil backed roof Insulation blanket is supported by the original timber tile battens that are left in place during the roof replacement.

Weight reduction

Did you know that the weight difference of a tiled roof compared to that of a metal roof is 10 to 1? Consider that a medium sized home has a tiled roof weight of around 15 Tonne. This same roof following a full roof replacement to Iron roofing ( or Colourbond ) will have a weight of around 1.5 Tonne. This includes all the Insulation and new framing members and sheeting. This drastic weight reduction certainly helps with preventing further cracking in the house structure and sagging in the roof members. We often need to straighten and repair trusses and roof members during the process of the roof replacement process. We have found from experience that once straightened and all sagging has been rectified, the roof structure usually experiences no further sagging as the weight reduction and bracing effect of the new iron roof sheeting prevents this.

After a full roof replacement you will be able to admire the look of your new roof every time you see it. The before and after effect of converting from old dirty tiled roof to shiny new Colourbond is very significant. Check out all the before and after images in our Gallery and see for yourself. We only use top quality Australian made corrugated roof sheeting on all our tile roof replacements. We set our new tile battens nice and close at 900mm maximum spacings to ensure a nice flat roof surface for the new sheeting. Our screw lines are always super straight and flashings installed neatly to give the roof the best finished appearance. With all the new roof colours in the modern Colourbond range it’s not hard to find a great colour that can really compliment the look of an original home.

Noise Suppression

We have found over many years doing roof replacements that Some people are worried that a new Colourbond roof will be too noisy especially during heavy rain events; however this is not true with an Insulated roof. With the foil blanket being installed directly in contact with the underside of the roof sheeting the noise reduction is significant. Rain can still be heard but the noise is heavily reduced by the muffling effect of the Insulation blanket. This also practically eliminates the “creaking” sounds that can often be heard from an iron roof as it expands and contracts with the heat of the sun. The potential of pesky possums entering the roof space is also practically eliminated following a roof replacement. There are almost no entry points for vermin following a quality Colourbond roof installation. The same cannot be said for most old tiled roofs in Adelaide.

Dust and bushfire risk

In bushfire zones it really makes sense to replace a tiled roof with Colourbond. Tile roofs always catch leaves, twigs and debris that can easily catch on fire during an ember attack. When we do a tile to Colourbond roof replacement in a bushfire zone we always scribe all the ridge and cap flashings which means the roof is completely sealed off to the outside. In areas with many trees or in bushfire zones we recommend installing ember gutter mesh as prt of the roof replacement. The Ember mesh is designed to have a smaller aperture than an Ember and therefore prevent embers entering the gutter space. The dust in a roof space is also practically eliminated when replacing a tiled roof with Colourbond. None of the dust and pollen that makes its way in through the original tile gaps will be able to get in anymore making for a cleaner roof space. We also offer roof space vacuum cleaning and re-insulating of the roof space with a partner company as an optional extra when doing a roof replacement.

Increased property value

A replacement roof can be a great financial investment for a home. The value of your home will certainly increase following the installation of a new roof. We do many pre-purchase roof inspections for would be home buyers and have found that many people get scared off or heavily discount their offer on a home that may need significant roof work or a roof replacement. People often think that a new roof is worth more than it actually is and discount their offer on the property accordingly. With a new roof replacement the integrity of the roof would not be in question should the house ever be sold.
Before After


The before and after effect following a roof replacement are significant. As the slider image to the left shows the aesthetic difference is incredible when an old tired roof is removed and a nice shiny clean Colourbond roof installed. A new metal or Colourbond roof is fully sealed and means that problems like possums and vermin entering the roof space at night are a thing of the past. Also the dust, debris and leaves that always seem to enter the roof space of a tiled roof are no longer a problem. When you replace a roof with insulated Colourbond you will find heating and cooling costs are also less. Add up all the benefits and you will find why replacing your roof could be one of the best investments when planning to stay in a home long term.

Metal roof replacement

If your property has an original metal roof that is showing signs of rust or is old enough to be fixed with nails it may be time for a metal roof replacement. This type of job is cheaper and less labour intensive than the tile to Iron conversion. We do recommend however to install a roof insulation blanket under the new roof sheeting. Most original roofs do not have this and we have found it’s a great investment when paying for a roof to be replaced anyway.

As part of our roof replacement process we inspect the structure and timbers when the original roof has been removed. If there are problems needing fixing or if the roof is better to be reframed with metal battens we will make that recommendation to you at the time. Just as with our tile to iron conversions we use True Oak Deep 21mm roof sheeting on each and every project for the same reasons. Oz-Roof are also capable of replacing commercial and industrial property with all roofing profile types.

terracotta roof tiles restoration


Probably half of all our tile to iron roof replacements are from Terracotta roof tiles. Terracotta has some benefits in that it never fades but certainly has its downsides too. It is very common for a Terracotta roof to start fretting at a point of age somewhere between 40 and 80 years. Fretting simply means that the tile begins to start crumbling away and is really progressively turning back into the very clay soil from which it was made. Once they start fretting there is no way of stopping it and therefore the best thing to do is to convert the roof to an Iron roof before the problem gets too bad.

Roof replacement with solar panels

These days most roofs have solar panels installed. We are often asked what can be done when it comes to roof replacement when a roof already has solar panels installed. We work with several solar electricians in Adelaide on a very regular basis. It is as simple as one phone call for us to have a solar system of any size removed and reinstalled after our roof replacement is completed.

For Tile roof replacements and conversion to Colourbond roofing we need to use all new mounting components and solar panel rails. This is because the mounting components are specific to either Colourbond or Tile roofing. We generally arrange to have the solar panels removed in the week prior to us commencing the roof replacement work. We try to get them back on as soon as their respective piece of roof has been re-installed, often going back on before we have even left the site.

The solar electrician always checks the integrity of the solar panels themselves, making sure there has been no water damage or cell failure before going back on. If they find any problems, you will be notified and have the option of replacing components if need be.


We are Not a franchise!

We are a locally owned and operated roofing business servicing the local area. When you make a phone call to us it won’t go through to a national call centre. The person that inspects your roof will issue the quote and then manage the job to completion.

No Money down!

We have a no money upfront policy. While other companies charge a hefty deposit and often ask for a percentage of the job upfront to lock you in, we don’t play any of those games. We just ask for a $100 deposit and don’t ask for a cent more until your Roof replacement is fully complete and you are 100% happy with your new roof. No risk, No pressure. No BS.

Competitively priced!

Because we aren’t a big company with huge overheads or part of a national franchise system we are able to be very competitively priced. From years of feedback, we have found that we are generally 30% – 40% cheaper than the big name brands and franchises – This is while delivering a quality of work that exceeds our competitors. We can usually give an approximate figure over the phone based on online imagery. For more information please visit our detailed blog post on roof replacement cost in Adelaide.

We don’t play sales games either.

We generally give you a fixed price quote verbally at our roof inspection and then follow it up with a formal quote by email.

No “for a limited time only” No, “If you sign up today we will give you a fake discount” No, “Free plasma TV for this week only” We just give up front discussion and quote with no games.
