Interesting. Why is that? Seems like a fairly obvious extension to keep in mind, at least at this stage.

Roofs aren't flat, aren't designed to support extra weight, and/or filled with antennas and HVAC equipment. If you want a building to have a helipad the architect usually has to plan for that from the start; retrofitting existing high rises would be extremely expensive. Plus upper floor occupants will complain about the noise.
