Like Mr. House says, if you install rows of panels tilted to each side of your bus then you'll almost always have one row which isn't working as well. You can minimize the impact by putting each side string on a separate charge controller, but that only keeps the shaded panels from killing your array...it won't solve the problem of one side being angled the wrong way.
Personally, I mount the panels flat and securely enough that I don't have to worry about lift. I would not install flashing, because having freedom for air flow below the panels can help keep them cooler and more efficient. But that's my personal preference and there are aesthetic reasons one might want a flashing. I even considered something like that, but with faux windows, to make a fake trolley top to hide the panels on top (on a vintage bus).
