The way I see, as for the pros and cons of metal roofs, we will image that in our mind, such as:

Pros:

1)Long service life than other materials;

2)More gorgeous;

3)Much convenient to split it up if nessary;

4)Relatively lighter than ceramic material ,etc.

Cons:

1)Pay more attention to the lightning-protection due to the conductivity of metal;

2)The metal roof need to be protected against rust;

3)The common problem of roof leaking.
