Roof - Colourbond vs Tiles

With the thick insulation blanket its not as noisy as with old corrugated iron roofs, but is still noisier than tiles.
The biggest benefit in my opinion is structual - a tile roof on average can weigh around 8-10 ton versus a metal roof weighing 2- 3 ton. 8-10 ton is a lot of weight on top of your structure.
I also think colorbond looks heaps better than tiles.

Colorbond or tiles is possibly more of a personal choice as to the look of the home.
Thermally, a pitched roof with a flat ceiling that has sarking directly under the roofing material performs much better than a roof without as it creates what is referred to as an 'enclosed' roof space.
Ceiling insulation 'performs' better as the temperature variations are more controlled by creating a still air space.

Hi Perthgirl

Other considerations may be if there are any council regulations on what roof you can use, plus if you go Tiles you may need to consider clay v's concrete.

At the end of the day you should also remember that the roof will impact the style of your home.

Best regards

We chose a colorbond roof over tiles mainly becuase of the SES (State Emergency Service) background both my wife and I came from. In 5 years of attending call outs due to storm related damage we have never seen a colorbond roof recieve as much damage as a tiled roof (colorbond bends and dents when a tree lands on it, tiles smash and shatter).

Once we made that choice we then took some steps to minimise and noise and heat issues. We have the standard R2.5 batts in the roof space, we also had installed fibreglass blanket insulation (aluminium foil on one side fibre glass wool on the otherside) with a rating of R1.9 underneath the colorbond sheets (between the roof battens and the colorbond) and then installed a whirlybird vent at the highest point of the roof.

All this goes together to prevent any moisture build up in the roof space, reduce the heat in the roof space significantly and the fibre glass blanket has the added bonus of being nearly completely sound proof, we have to stain to hear the rain on the roof.

Hope that helps.

Colorbond is a bit dearer than tiles. Insulation is pretty much the same for both. Most councils specify R3.0 minimum batts in the ceiling now and the fibreglass blanket under the roof itself is required for both generally.
