If your original house roof is leaking and showing signs of age or is beyond repair, it may be time to consider re-roofing. Re-roofing is simply the process of removing the original roof surface, be it tiled or iron and installing new Colourbond roof sheeting. The original tiled or metal roof may have become brittle or showing signs of corrosion or rust. When a roof reaches this point it’s best to stop investing good money in the original roof surface and opt for a higher cost yet better value option of re-roofing. Re-roofing will increase the value and aesthetic appearance of your home instantly. It also allows for the performance of the roof to be enhanced by Insulating the new roof sheeting as part of the reroofing process.


As concrete tile and terracotta tiled roofs age they lose integrity and begin to become porous and brittle. Without regular roof maintenance a tiled roof may have run its usable life after 40 – 50 years. At this point our recommendation is always to re-roof with Colourbond roof sheeting. There are many benefits of this type of conversion. 




We highly recommend Insulating new roof sheeting during the re-roofing process. With the hot Australian summers this is of huge benefit as the heat transfer is slowed down rapidly right at the roof surface. We generally use a 50mm foil backed Insulation batt from CSR Bradford however there is also the option of upgrading to 75mm for even greater Insulation. With most older Australian homes really lacking in Insulation this becomes of great benefit. We also offer a service of removing all original ceiling Insulation from the roof space, vacuum cleaning the entire roof space so that it is dust free and re-lining the ceiling with a heavy duty R4 Insulation batt. This combined with the R1.3 Insulation blanket installed directly under the roof sheeting can see some older homes going from almost no R rating at all to R5.3.

Weight reduction

Most people don’t know that a concrete tile of terracotta tiled roof is one of the heaviest elements of the building. An average medium sized house will have around 12 Tonnes of tiles cladding its roof. When we reroof a property with Colourbond Iron roofing we generally reduce the roof weight by around a ratio of 10 to 1. That means for every 10 tonne of tile surface removed we re-install 1 tonne of Colourbond roofing. Obviously the weight reduction helps with preventing any further cracking in brick walls and any continued sagging in the timber roof structure.


Other than all the performance enhancements gained by re-roofing the most obvious is the visual or aesthetic difference that reroofing can make. There are so many new colours in the range or Colourbond steel that all look fantastic on older houses. Check our gallery for many before and after images and see how an older house can be completely modernised with reroofing.


One of the most common questions we receive when discussing re-roofing with a new potential client is around roof noise and particularly the amount of roof noise during rain. This is just another huge benefit of lining the new roof sheeting with an insulation blanket. The rain noise is reduced considerably, almost as quiet as a tiled roof. Also the creaking noises that can often be heard as an iron roof heats up and cools down each day with the sun are completely eliminated with an Insulation roof.

Dust and bushfire risk

For re-roofing of an original metal roof the panels and rails must be removed but the original hardware can generally be reused. The solar guys always check 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 always be notified and new panels can be an option.

Before After


At Oz-Roof we really don’t use square metre rates to price our re-roofing projects. We attend each job and inspect the roof and the whole site for access before giving a formal quote. Some of the bigger factors that affect price are the pitch of the roof and the access to the roof edge. These two factors alone influence price more than the outright size of the roof. A low pitch roof comes with reduced difficulty and therefore reduces labour. The opposite is true for a steep pitch roof. When looking at access we try to find the most efficient way of getting our work done. There are many different types of re-roofing. From Iron to Iron and from tile to Iron are all different prices. Also no two properties are the same and for that reason the below is just a rough price guide.

As a rough price guide:

Re-roofing on a smaller roof with good access and simple roof design could be $18,000 – $20,000 + GST
Re-roofing a moderately sized roof with reasonable access and typical design could be $20,000 – $25,000 + GST

The above price guide includes insulation for the new roof sheeting.

If you would like a ballpark figure on a re-roofing job for your property then give us a call. We are more than happy to give information over the phone and for most straight forward jobs we can make a reasonably accurate estimate from online imagery. If you are happy with the online estimate figure we can then arrange to come out and inspect the site, discuss the re-roofing process in detail with the homeowner and issue a formal quote.

These days it very rare for us to re-roof an original tiled roof with tiles. The re-roof process is almost always done with Colourbond as this allows for many additional benefits over the original tiled roof, weight reduction and improved Insulation just being a couple. We find many Terracotta tiled roofs that are 40 – 60 years old have started fretting and crumbling away, this is especially prevalent with home within a few kilometres of the sea. Our suggestion when finding this is always re-roofing in a nice new Metal roof.


These days most roofs have solar panels installed. We are often asked what can be done when it comes to roof reroofing when a roof already has solar panels already installed. We work with several solar installers 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 work has completed.

For Tile roof reroofing 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 re-roofing process. 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.

For re-roofing of an original metal roof the panels and rails must be removed but the original hardware can generally be reused. The solar guys always check 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 always be notified and replacement or new panels can be an option.


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 re-roofing project 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.

Specialists in roofing

We just do reroofing and do it really well. We won’t try to sell you Roller shutters or Solar panels or steak knives or pizzas! Roofing is what we know and love and the only thing we do. Don’t go with a company that sells everything under the sun, they can’t possibly take their roofing as seriously as we do.

Backing of the big name manufacturers!

We might be a small company but through a proven history of quality work, we have the backing of some of the big name suppliers in the Roofing Industry. We use top quality roof sheeting from Blue Scope Colourbond and Revolution Roofing on all our reroofing projects. These products are the best that money can buy and have the longest and strongest warranties to back them up.

Tradesmen not salesmen

The person that comes to your house is a tradesman of many years experience that really knows roofing. We are not a company that sends you a high pressure sales person with no real industry experience who will probably be selling Indoor blinds at his next appointment. 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.

Five reasons why:


When re-roofing, we highly recommend lining the new roof with an Insulation blanket. It’s a great way of increasing the energy efficiency of old homes that were built prior to the 6 star energy rating system. With roof insulation blanket the thermal and acoustic performance of a roof system can be dramatically improved.
