What temperature should a sirloin roast be?

Online Answer
Insert the probe of a meat thermometer into the very center of the roast. Place in oven, and roast until you reach an internal temperature of 130 F for medium rare. For each additional 'step' of doneness, add ten degrees. So medium would be 140, medium-well, 150, and well-done 160.
