There is no reason to remove the roof of the golf cart for transport. The fasteners are strong and the plastic on the roof is made for transporting it. If you are going to trailer your golf cart you should make sure that the cart is going in the direction with the wind otherwise your golf cart windshield will split and fall off. You should trailer your golf carts with the windshield intact but folded down. You should also tie a piece of string around it to reduce the possibility of it moving.
The cart will go faster if the angle increases.
