Site specific limitations - Thickness of growing media, specifically: Weight -.
In this article, we go in detail into what a light weight Green Roof is, what could be expected in terms of plant diversity and water/air available for green Roof plants.

Generally speaking expectations should be in line with what is technically possible when considering a projects limitations (weight)
Once you understand what plays a role when considering a thin layer of growing media, and thus decreasing a Green Roof’s weight, expectations could be adjusted, avoiding disappointments –ore- building technical limitations should be addressed, in order to accommodate a green roof system that within reason preforms to expectation.
Expectations should not exceed what technically is hard to achieve !
