Putting Colorbond over concrete roof tiles

Hi

New here so go easy please , I have a concrete tiled roof that I want to replace with colorbond I was writing about this on another solar panel related forum ( there are 24 panels on the roof plus apricus hotwater system ) and someone suggested to lay battens and then put the colorbond on leaving the tiles there . This would 1. save removing the tile and 2. add to the R value of the roof .

Roof strength would be one issue are there any other issue I should think about ? I have two skylights and two domes ?

Cheers

Never heard of anyone doing this before and I'm not sure its a good idea. It would be a big job to fix the battens down over the roof tiles and would most likely end up cracking a lot of them. The roof will also be too high for the fascia and gutters.

Yeah well i talked to the roofer today and it could be done and hes roofed over absetos but all the issues like raising the gutter line , engineering for the extra weight even maybe council approval becuase of raising the roof line come into it , mean its easier just to remove the tiles .

Thanks for the reply Flatlined .
