Guys I have a question regarding green roof. If the area happens to be in a strong wind area, is it still recommended to have green roof albeit its sustainability? What structural challenges is it facing? What can be done to prevent the uplifting?

Any thoughts will be appreciated. 

Thanks

  I doubt this would ever be an issue, though in real-world applications I would make sure the proper engineers confirm. I found this article and there are several others just from searching for it on Google:

  Lu Han,

  What is your primary concern for this question to arise? Did you see this question in a study guide that provided an answer that is confusing or something? The only thing I could think of that would cause a vegetated roof to be a problem in a high wind area would be its angle. For example, in South Florida we're not allowed to have vegetated roofs on a slope greater than 30 degrees, not to mention it can't even be called a vegetated roof, but rather a "planter" in order to pass building plan review!
