There's gotta be a code for it, in most places anyway.. ask Payson about that one lol.
Around here I've seen buildings over 30' tall with no access anywhere. But I've seen buildings I could get on with an 8' ladder with a fixed ladder on them.
If I were an engineer I'd have a stairway (the kinda steep kind) access to every roof for a building I designed. I know how much it sucks going up a verticle ladder with tools, or up an extension ladder that barely reaches.
Hummmmm... perhaps an elevator to the roof instead?
