While I think this is a great idea, I'm doubtful that the advantages significantly outweigh the disadvantages.
Another notable disadvantage is that if you plan on growing anything more than grass and flowers AKA a tree, you're going to need significant soil depth in areas. This means that the building is going to have to cope with not only soil weight but of the soil becoming super-saturated with water. The drainage of the soil so as to avert too much water sitting in the soil. So on and so forth. Adding hundreds of tons of soil and water onto the roof of your building is going to put excessive demands in place and sky-rocket construction costs in your urban core. Given that many cities have a problem keeping businesses in their urban core, I don't see how making it more expensive for them would be beneficial.
