Hi Rita..... A true flyover stays separate from the main roof......the rain can either free fall from the lowest point of the flyover on to the existing roof below and collect with the water from the main roof and down the drain pipes, or it can have it's own guttering and down pipes (how to make that aesthetically appealing depends on shape of your roof/house and height of the flyover). Hubby is a builder and HATES box gutters, but a properly done flyover is no issue at all. Good luck :)

Thank you for your comments - I did a bit of a mock up with various colours and am erring towards a darker colour as it would blend in more. When I zoomed in on the photo I noticed the house down the front of the view has a monument colour roof so that gave me a bit of insight into how a dark colour would sit amongst the trees - if I wanted to tint it a bit more towards the water colour (although this changes on a daily basis!) I could use ironstone which is like monument with a touch of blue. The heat adsorption by the darker colour doesn't worry me as much as our roofer says it doesn't make that much difference as we will have insulation - it outweighs the reflection issue that a light colour would have. As far as making it a trafficable space - there is no shortage of viewing platforms in the rest of the house - I did do the sums on a rooftop garden and am tempted but at this point it would add about 8k for extra support, 8k for waterproofing and then about 20k for all the rest - although I suspect I could do this last part cheaper than that quote. The block is not short on garden space!

So to update @MB Design & Drafting, I’ve now discovered that the sheets are dodgy cheap Chinese? Products NOT from bluescope HENCE scratching when just looking at them! Does anyone know the legalities of challenging cheap imitation installs? I asked for colorbond colour/sheets. So I have a leg to stand on? Clearly colorbond warranty doesn’t now apply... there is vapour barrier paper/sarking also missing where they didn’t overlap rolls along the dorma window ridge line. I’m also guessing this doesn’t pass compliance since there is no moisture barrier from sheets to ceiling below?

Thanks for the replies. I think regardless ill need to paint the posts a darker colour, so you arent seeing the red colour through the boxing. Any advice on the painting would be appreciated :)
