Great comments all! Hope I can remember the when its time for my next roof,,,

Note that metal roofs come in varying qualities. Plus installers should be reviewed.

Metal roofs can now look like slate, shakes, - not just plain. Most think that all metal roofs look the same. Not.

The cost of metal roofs usually is sizably more then a shingle roof.

There also can be a snow slide issue for some.
If I were to construct a new home, yes, I would give a metal roof serious consideration.

But yes, having the porch roof metal could be an option for the OP.
