No way will you ever change the identity of that home. It's a losing battle. And you're wasting your money to even try.

Changes like this should be well thought out and planned -- preferably with the help of a design professional.

It's key that changes and additions appear integrated and not as an afterthought, and enhance, rather than detract from the overall design.

I don't see this porch working with the house.

You might also check the rise going from step to step as the picture seems to show a difference between the middle and top tread.

Horrible idea for the roof. Adding anything with a roof needs to match the roof pitch over the garage---and there is not enough room on the front of the house to do that(2d floor window in the way).

Metal roof would be a sore thumb, glaringly out of place.

If the steps/etc. are yours, the rise of each step is off(as PPF pointed out). That is a safety issue as well as not code compliant.

I agree with HandyMac. Maybe if you wanted to fork out a lot of money you could do a copper roof, but metal wouldn't go with the style of the home at all, let alone the rest of the roofing.
