It is important to note that a cantilever is not just an overhang supported by a wall or column. Your contractor integrates the cantilever into the structure of the building. The overhang is an integral part of the structure and not just an add-on.
There are some circumstances when you might not want to use a cantilever roof overhang. One is if you live in an area with high winds. The extended structure can act like a sail and catch the wind, putting stress on the building and causing damage.
Thermal bridging can create significant energy losses and the potential to develop condensation and mold. You will need to work with your engineer and builder to design a thermal break if you live in a hot or cold climate.
