not long at all. like with any meat, if it's out of refrigeration for long periods of time it will spoil. the climate where you are can also affect how long it can go without refrigeration. If you made roast beef for sandwiches down at the beach, it should be fine for the drive down (though I'd put it in a cooler to be on the safe side). If you live in a really warm, humid area, the roast beef'll probably go bad in a matter of hours if not refrigerated.
