Answer to OP: it depends on why you're using them.
I use rollers (mostly in off-season) for 10-20mins after my on-the-road-rides to enhance my pedaling technique (pedal in circles).
But, I own a trainer, too. If there's bad weather or no place else to warm-up, I use it before races where it's important I be warmed up before the start. Although, I have used rollers prior to races for warm-ups as well. They work, too.
