What considerations should be made when installing a green roof on a metal building?

我们的建筑只有不到600平方英尺，目前是金属屋顶。它有一点倾斜，但我们住在德克萨斯州东部，预算非常紧张，想要自己做所有的工作，但我们在松树之乡经历的极端高温和天气让我们质疑什么植物足够轻，并且能够在没有广泛根系的情况下承受高温。
When you ask aboutinstalling a green roofon a 'metal' building, you are referring to the current roof covering, correct?
We do have aDIY green roof installation video, the first steps of this process (linked below) would be the same, in that you need awaterproof roof covering, then aroot barrier, and certainly for a green roof in a desert climate you would want adimpled drainagemembrane with the capacity to store water.
如果安装得当，一个有生命的绿色屋顶可以比许多其他屋顶系统持续更长的时间。
We would need more details in order to provide any specific advice in your case; are you considering leaving the metal on the roof and doing a green roof on top, is that what you mean by a ‘metal building’? Are you planning on building a green roof because the metal has deteriorated? I ask this because the process would normally start from the roof sheathing, so that metal would need to come off. Please let us know your starting point, and we can help set you off on the right track.
Thank you for answering so quickly! Where we are, we actually get A LOT of rain. We are a subtropical climate in the piney woods of east Texas. I would prefer to take the metal roofing off, so that isn't an issue, my main concern is how to know what kind of weight a "metal building" built in an area with no snow would be capable of. In addition, we can get down to 20 farenheit (high humidity), and up to high 90's (high humidity) summertime. I will be saving up, and begin fundraising this year. (It is for a non-profit), so I really want to get an idea of what we're facing.
We can advise you on the general steps to take to protect a roof, but when it comes to the structure, we would not be able to offer any advice sorry. You should have an engineer determine that. It doesn’t sound like you have a ton of cash lying around and I wish we could help more, but there is no way for us to know remotely what sort of load an existing structure could handle. You could check with the municipal building department and they may be able to offer more advice than us.
