Roof Replacement and Re-roofing Services

Top quality re-roofing and roof replacement services for all residential property in Adelaide. Specialists in Tile to Iron conversions and total roof replacement.


When your Concrete Tile, Terracotta Tile or metal roof is beyond repair it may be time for a re-roof or 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, and invest a little more in the appearance and performance of your roof by re-roofing or roof replacement.


The ultimate and best type of roof replacement is a Tile to Iron or (Colourbond) conversion.

The benefits of this type of roof replacement are many:


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 conversion, we highly recommend our clients to pay a little extra and have Insulation blanket lining the new roof. 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 a tile conversion as the foil backed Insulation blanket is supported by the original timber tile battens that we leave in place.

Weight reduction

Did you know that the weight difference of a tiled roof compared to a metal roof is 10 to 1? Consider that a medium sized home has a tiled roof weight of around 12 Tonne. This same roof converted to Iron will have a weight of around 1.2 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 Tile conversion. We have found from experience that once straightened the roof structure usually experiences no further sagging as the weight reduction and bracing effect of the roof sheeting prevents it.


We have all seen the Advertisement of the guy picking up the newspaper from the front lawn and looking back in admiration of his roof. You can do the same after a tile conversion. We only use the Revolution Roofing True Oak Deep 21mm roof sheeting on all our tile conversions. We make this a zero cost upgrade on each and every job. The deeper corrugations make the product significantly stronger compared to standard depth roof sheeting. It also looks better with a nice shadow line. There are many new additional colours in the Revolution Roofing range and the warranties are fantastic.


Some people are worried that a new Iron roof will be too noisy especially with rain however, this is not true with an Insulated roof. With the foil blanket directly in contact with the underside of the roof sheet most noises are suppressed. 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.

Dust and bushfire risk

In bushfire zones it really makes sense to re-roof with a tile conversion. Tile roofs always catch leaves, twigs and debris that can easily catch on fire during an ember attack. When we do a tile conversion in a bushfire zone we always scribe all the ridge and cap flashings which means the roof is completely sealed off to the outside. We usually install fine metal Ember leaf mesh to all gutters in bushfire areas to ensure that gutters are not full of leaves. The Ember mesh is designed to have a smaller aperture than an Ember and therefore not allow embers to enter the gutter space. The dust in a roof space is also practically eliminated when converting to an Iron roof. 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 with a partner company.
Before After

Why Our Clients invest in Re-roofing

At Oz-Roof we really don’t use square metre rates to price our jobs. We attend each job and inspect the roof and the whole site for access before giving a quote. Some of the bigger factors that affect price are the pitch of the roof and the access to the roof edge. These 2 factors alone probably influence price more so than the out right 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 removing the 12 – 20 Tonnes of old roof tiles from the roof and getting them in a skip and off site.

If you would like a ballpark figure on a Tile conversion re-roof for your property then give as a call. We are more than happy to give information over the phone and for most straightforward jobs we can make a reasonably accurate estimate from online imagery. If you are happy with the ball park figure we then come out to the site and do a full inspection and issue a fixed price quote.

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 re-roof or 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 re-roofing 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 re-roofing commercial and industrial property with all roofing profile types.


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 and 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 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 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 and metal roof replacement projects 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.

Why use Oz-roof over other roofing contractors?

We are Not a franchise!

We are a locally owned and operated roof restoration 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 restoration 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 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.
