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.
The roof is green because it is made from copper, which turns green from erosion and weather.
A green roof may refer to one which is living, and has plants growing on it. It is best to refer to an expert in these systems as damage can occur. In general one places a waterproof fabric over the concrete roof, then a growing medium, then the actual plants.

The best type of green roof for installation typically depends on the building's structure and desired maintenance level. Extensive green roofs, characterized by shallow soil and low-maintenance plants like sedums, are ideal for lightweight applications and require minimal upkeep. In contrast, intensive green roofs allow for a wider variety of plants and even small trees but require more structural support and regular maintenance. Ultimately, extensive green roofs are often preferred for residential applications due to their ease of installation and lower costs.

I believe you mean thatched roof. It is a green roof made of materials at hand, i.e. reeds, bamboo, leaves
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)
The shingles on my roof are beginning to wear out. Do you know where the best place to buy roof shigles is?
