Pretty much any roof system is going to need cleaning from time to time, and the caulking where any seams or items perforating it are will need ongoing maintenance. (There are some sprayed-on elastomeric roof systems, somewhat akin to pickup bed liners, that claim otherwise...but I remain a little skeptical of that absent independent verification.)
That being said, my impression is that fiberglass and metal (generally aluminum) roofs tend to require less TLC and last longer than TPO or rubber ones, and TPO tends to last longer than rubber (EPDM). Rubber probably lasts on average 15 or 20 years before needing replacement. There are definite variations in quality among different roof systems of the same general class, too; some are much heavier duty than others.
