Some kind of covering that we can place on the existing roof to give it a bit more decoration. It would probably work like the flooring tiles do currently, just on the roof. There could even be special designs such as the Tom Bradley Terminal or one like Madrid.
Currently, the architecture is really bad (I’ve never even seen an airport without some kind of roof) and these roof tiles could add a lot more creativity to the game.
Considering that decoration/aesthetics are supposed to affect airport rating properly from Alpha 34, you could add roof decoration to the list of things that improve that rating
It would be cool if you could customize your roof material, (like concrete, basalt, granite, marble, or metal). After choosing the material it would take you to a grid looking screen where you could click and drag out points to add depth to the roof.
I know that this might be the traditional ACEO ways of adding these different accessories into the game, but that limits many people to what the community decides to make. I think inspiration can be shared, but mostly you can make your own and experiment with it.
