Be careful, if they have not been making these for over a year, that means that the ones you buy have been stacked somewhere for that period of time and might be difficult to separate. Also just because no one makes a shingle with a particular name for the color does not mean someone isn't making the same color and using another name. Take a sample and check out all the places you can find that sell shingles. It is not likely that you are going to find a perfect match anyhow because of fading and weathering. Buy some that are just a bit darker and pretty soon they will match pretty close.

I'm no decorator, so take my opinion as that. It is said the roof is 40-50% of the curb appeal of a structure. It appears as if you have a 10/12, maybe a 12/12 pitch. So you have a lot of roof showing from the "curb". I personally installed a competitors covering on my own home, called Colonial Slate, which has the red in it. My neighbor liked it so much, I reluctantly installed it on their home. Just wasn't thrilled having a roof just like mine, right next door. Anyways, I'm partial to the Williamsburg.

Looks similar to Certainteed Moire Black but it's really difficult to tell for sure. Since that picture is to showcase Certainteed siding it's certain to be a Certainteed roof product as well. Look at their website for shingle colors.

We are doing the same - GAF Timberline HD in Charcoal with black standing seam metal on the porches and roof/cornice returns. I recommend you open up one of the shingle bundles and pull a few of them out to get a feel for how it really looks. Our actual shingles have much more gray in them which is what we wanted. The demo piece on display in the store was completely black and not indicative of the actual product at all. Seeing the actual shingles will help you better pick that metal.
