The height of a carport is in most cases, common sense. A tall person should be able to walk comfortably under the lowest end of the carport. 2100mm (7ft) from the finished ground to the underside of the lowest end rafter, is a good height.
The roof slope (fall) should be at least 100mm (4").
If using a clear PVC roof, then a steeper slope is advisable, as a steeper fall means faster water run-off, and therefore a cleaner roof.
