Tips. 1  If you're roasting the beef in a convection oven rather than a conventional oven, preheat to 275 degrees F. Take the roast out when the internal temperature is 125 degrees. 2  The roast beef's temperature will climb another 30 degrees following removal, reaching well-done. temperature of 155 degrees F signifies a well-done roast for most cuts of beef. Drape a piece of aluminum foil loosely over the roast and allow it to sit out for about half an hour.
