This depends on a number of factors. In most of the United States, you will want a roof with a steep pitch to allow the water to run off quickly. The roof should have a good system for allowing ventilation in the attic. I think a passive ventilation system is better than a mechanical, because when mechanical systems break down, homeowners rarely repair them. Radiant barriers have not been studied enough to make a proper determination of how they effect several parts of the roof system, but I feel that the barriers on the back of the sheathing or the foil sheets is good to install (the paint on system is not good for high humidity areas). As for the roof covering, a lighter colored material is the best for reflecting ultraviolet light. Some metal shingle manufacturers have made claims that their product has done well at improving this factor. By reflecting ultraviolet light, you reduce the heat in the attic.
The question also depends on how one defines the term "green roof system", if one means a roof made of ecologically friendly materials, that is one thing. If one means "green roof system", as in a "vegetated roof" or "eco roof" or "green roof", that would mean something completely different.

What the different between green field towers and roof top topwers?
I've been haunted by the same question for a week. Unfortunately, I'm just a translator, not an engineer. My best guess is that green field towers are used in suburbs, while roof top towers are used on the roof top of buildings, where you just cannot manage to get sufficient space on the ground (or you can, but for a ridiculous price...) Also, I noticed that green field towers come with foundation, while roof top towers come with foundation and installation kits (for mounting, I presume)
How are renewable resources being use in a green roof?
I am not aware of any renewable resources being used in green roofs, although it is possible. Green roofs are called green because they are covered with soil and vegetation. The roof surface does not get hot like a regular roof thereby saving energy for cooling the interior. Water is retained by the roof surface which reduces the amount of water required to keep the plants alive.
