I’m pretty much out of my league on design sense when it comes to a higher end house like this. The garage is likely bigger than my whole house. And I think you want a darker shingle, which is more dramatic. So I only post because you mentioned charcoal, bluff, and grayish.
I went with Landmark Aged Cedar, which is actually more grayish than it sounds. But it’s the kind of gray that is more like you see with charcoal on the 5th of July.
It does have a tinge of bluff/tan in it, but not much.
I actually changed the color part way through the process to a darker brown/redish shingle, but that change got lost in the process, and I ended up with my first choice - the aged cedar.
Love the way it looks now, and love the contrast between roof and fascia - I like the way it shows off the roof lines.
Now I have to figure out what color to re-paint the house to best match the roof.
So I just post this comment because the roof color has actually re-defined what I want for the rest of my house. I had a friend that said nobody pays much attention to the roof, just get it done. And, respectfully, I have to disagree.
So that worries me a little here, that the whole rest of the house/colors are already decided, and now comes the decision for the shingles and their color?
I’m a programmer by trade, so it was drilled into me to do things in top-down ways I guess. So that must also be carrying over to what I do with the house
Almost forgot the pic of my shingles… http://www.gthomson.us/projects/roof/new/curbview1.jpg
