More ventilation if I add insulation?


I am adding insulation to my attic going from an R-30 to R-49 or possibly R-60. I have soffit vents and proper baffles, a gable vent on the east side, and a ridge vent. I was told by a contractor that if I add insulation, I need to add roof vents as well. Is this true? Thanks for your help.
