Jenny, I apologize, for some reason I am just now seeing your question, 2 years later! This has the look of faded charcoal gray color - it is actually the original roof from the BEFORE shots and is decades old so I don't know the product, just that these metal roofs last a very long time. But an internet search of "standing seam metal roof" will yield you what's available on the market today - there are a wide array of colors available and they can last 50-100 years.

Since writing this, I have revisited and Sophie and Kent's family size has doubled. thus they have the two-story addition they had plans for all along on the right side of the house. I'd love to get back and take pictures next time I'm in town to show everyone that next phase.
