What You Need to Be Aware Of

Two main issues need to be considered.

A colorbond roof is a lot lighter than a tiled roof. A tiled roof will weigh, on average, 60kg per square meter. At the same time, a colorbond roof will typically be just a fraction of this weight at around 5kg per square meter.

A local council would likely require planning approval and a building permit. The Building Code of Australia may well have changed since the home was initially built.

The main challenge when converting a structure from a tiled to a colorbond roof is the dramatic weight reduction—this significant change in weight conditions. When coupled with high winds, it can create significant uplift on the roof and, hence, potentially damaging issues.

A colorbond roof that has not been professionally installed. Utilizing the correct tie-downs can be like an umbrella in a high-wind event.

So, the issue now becomes not about holding the roof up. But instead, pinning down the roof in a high wind event. The Building Code of Australia requires the roof frame to be tied down to the house as defined in Australian Standard 1684. This is where Powerdrive Roofing’s building inspectors ensure everything conforms to and exceeds the current Australian standards. On every roof replacement we undertake.

Roof Leaks

Although our first option is always going to be Roof Repairs or maintenance, it is to be expected that building materials will not last forever and eventually, all building materials (even concrete roof tiles) will break down and it becomes more economical to replace the item rather than pay for constant repairs. Our team will give you a range of realistic options after an onsite assessment.

Loss of Water Resistance

The waterproofing qualities of tiles (particularly cement tiles) will break down over time. The tiles will need a Roof Restoration or Roof Replacement; depending on the age and quality of your tile, our team will give you options on-site.

Damaged, Cracked and Broken Tiles

When there are a large number of broken and or cracked tiles that require replacement, many of these tiles have broken water channels due to being sheeted in too tightly when installed initially and general movement in the roof frame over the years; when this happens, it can be impossible to get all broken tiles and therefore impossible to give a warranty on any Roof Repairs undertaken.

Why Metal Over Tiles?
There can be a couple of main reasons:

Aesthetic Reasons
Some people choose to change their tiled roofs purely for aesthetic reasons because they prefer the look of colorbond roofs over clay or concrete tiles.

In general, changing to a colorbond Roof Replacement was cheaper than tile-to-tile Roof Replacement on a residential property. However, due to its popularity, the cost has skyrocketed.

Roof Replacement Tile to Tin

Converting an old tiled roof cover to a new colorbond roof cover (for example, a Colorbond roof) is quite common throughout Perth, WA. There is the right way and the wrong way to undertake this conversion and Powerdrive Roofing knows this all too well. The wrong way can cause problems with the structural integrity of the building, not only rendering it dangerous but also creating challenges for homeowners when attempting to sell their property down the track.

So Why Change from Tiles To colorbond?

People have a variety of reasons as to why they decide to change from tiles to steel or tin.

Spalling Tiles
Tiles, especially clay, will not last forever. Eventually, the tiles will break down and lose their core attributes.

Chemical Delignification
Spalling of tiles and chemical delignification generally go hand in hand.

Although Powerdrive Roofing is Australia’s only proven Chemical Delignification Treatment Specialist, sometimes our customers choose the option of a New Roof instead. Other times, the Delignification is too far advanced even for the experts and a New Roof is recommended.
