Google battling ‘fox infestation’ on roof of £1bn London office

I hope they shit in their vents.

Soil is quite heavy. So a rooftop garden may require a reinforced building structure, which require extra resources. And insects and animals may try to settle on your rooftop garden. This kind of architecte look nice but often is a bad idea.

Put solar panels on rooftops, and create a garden on an empty lot. Not the other way around.
