what is your existing roof?

If both tiled or colorbond steel roof are installed correctly, then neither will leak.

We currently have a tiled roof I prefer this but most of my friends and family have high ceiling colourbond roofs and leak. We do love the style and look of colourbond steel.

So it's a dilemma lol

You should look into why your friends colorbond roof leaks.
It maybe something to do with blocked gutters or not enough down pipes. Colorbond is water proof if installed correctly.
Tiles are also waterproof, if there are no cracked tiles and cementing is in good condition.
If you do not maintain your home, then things happen.
So it is personal preference, and the style of finish you are after.
If your existing home is tile, then have tile.

we have had experience with numerous Colorbond roofs over more than 40 years without any problems although we had constant leaks in a tiled roof with a box gutter that wasn't designed and built properly...Colorbond steel is excellent as long as it's installed correctly with the correct steel profile, overlap and fixings for the angle of the roof and proper insulation etc and the same conditions would apply to a new tile roof

Reasonable pitch on roof and avoid box gutters and deciduous trees or trees that drop bark or pollen overhanging roof, Colour bond should be better
Cracked tiles or silicon seals in gutter ends are the big issues with leaks plus gutters overflowing

@Katie Stait. Can't help it, but this just bugs me.
Its Colorbond, Not colourbond. Sorry, I feel better now.😌

Dreamer Tell that to autocorrect

My bad @dreamer
Sorry to bug you 🐛
I have a Sony Android phone, with a shocking autocorrect. It's actually on the way out. 😂 I am so use to Australian English spelling of the word colour as well that I just merely assumed.
