It depends on the method.. For example, flashing a unsecured kernel in order to root can void warranty since Samsung has a flash counter and anything above 0 = voided warranty
but you an purchase a USB jig that resets the counter so you're warranty is unaffected
DooMLoRD's root tolkit allows you to root/unroot your device withut having to worry about Samsung's flash counter.
