I would say that I don't have, exactly, what you want/need but I'd call it a good start. Here are a few links I found on the WEB that make/sell 'wood roof shingles':
Building.org - This 'list' includes a few of the links listed below. On the just-listed link, look for the URL that points you to Wood Roof Shingles. (I think it shows next to the link that there are 4 of them for you to look at.) When you're through with this link try these: Granville Lumber, Cedar Valley Shingles, ATAS International, and Sovebec of Canada
I don't know anything about these companies. If you're leaning towards cedar, as 'jb' says, you can contact The Cedar Bureau for info. Certainly, if you have more specific questions, ask away!
My best to ya and hope this helps.
