Tile vs colorbond roof

It’s brick veneer and putting a double storey extension on the front of the house. It has been suggested to clad and render the extension instead of brick and render.

Roof is gable roof and they will need to slightly modify existing roof for where it meets the new extension.

It is a nice sound! Not sure I would replace it just for that tho.

Why not to go for metal roof but which looks like tile (and costs like metal).

Probably the best of 2 worlds.

Based on that, I have two further question to ask:

1. Do you plan to own and live in this particular house for a sufficiently long time to get a return (with return defined any way you want - pleasure, increased amenity, improved efficiency or anything else) on the extra investment in replacing the existing roof with Colorbond?

2. If you are planning to move on in the first half of the life of a new roof, do you think changing over to Colorbond will improve the look of your home to such an extent that it will increase its resale value?

I went through a similar exercise with a home that we lived in for two years, and still own as a rental property. In this case, there was no extension to initiate the decision, but it was just based on our preference for a steel roof. I learnt a few things during that process:

* Concrete tile roofs rarely need to be wholly replaced, because individual tiles and capping can be removed as they crack, pointing can be redone if it breaks down, and the whole roof can be cleaned and recoloured if a change in look is desired.

* Concrete tiles are heavy and can contribute to the underlying frame sagging. However, even having to remove all the tiles to repair or replace the roof trusses may not make a changeover to a steel roof cost effective since you still own all the tiles, which can simply be put back onto the new frame.

* Because concrete tiles are heavy, there may have been no need at the time your house was built for the roof frame to be structurally tied to the foundations (or wall frames), but just relying on that weight to keep the roof in place. However, with a lightweight steel roof, lift needs to be considered, and that might require some re-engineering as part of the changeover.

In my opinion, it is only worth changing over to Colorbond if there are aspects of a steel roof that you will really enjoy (the look and/or the sound) and you are willing to pay for that enjoyment. If not, then I would just match the existing roof on your new extension.
