It's an IKO shingle product, the color of which I'm not sure. I just glanced at the IKO website, and I think it's Harvard Slate. See https://www.iko.com/na/shingles-by-color/?nickname=grey-shingles.
What color/brand is the roof?
The brick is Clayton Falls by General Shale. We've gotten a number of inquiries about it, so I guess folks like it. Obviously, so do we. Thanks for asking.
