Here's mine, installed last fall. We installed over top of the old asphalt shingles with 2x4 spacers and plywood, then the standing seam roof. That was $14k.

I'm very happy with it. There's no noise with the way it was installed. Mostly aesthetic for me but I think it was an improvement for the cabin in multiple ways. Now just have to get to the rest of the exterior.
I'm in Catskills btw, so depending on how upstate you are, send a pm and I'll pass along my roofer's contact. His price was significantly better than the other two quotes I got.
