Vertical Greening

I don't think a green roof will be consider vertical. If by vertical you mean something like a green wall LEED does not allow you to consider that one as a green area so it w ill be excluded from any type of calculation and credit regarding vegetation (please someone correct me if I am wrong). If you only mean greenroofs then they can be considered as green area so you can use it to comply with SSC5.1 only under the path restoring the site (if it has local and adapted vegetation) and you can also use it to comply with SSC5.2 under any kind of path. But remember, you can only comply with those two using a green roof not only if it has local and/or adapted vegetation but also if you are achieving SSC2 and your project is located in an urban area.
