What is your advice on leaving the old on and roofing over it?

My reason for leaving the old on is for two reasons . less cost to install a new roof and more insulation
Whatever you decide remember...."It only has to outlast you and the wife"... All kidding aside there is nothing wrong with putting new asphalt shingles over 1 previous layer.
