"Blue Slate Rooves on white buildings" (or buildings made of pale or greyish stones): this is typical for allegedly "Celtic" regions, Bretagne, French MidWest, Wallonia, high plateaux of Auvergne, but also Scotland, Wales and North-Western England.
The dominant material around Paris (the so-called Parisian Basin) is the brown flat tile. It is in my view the Frenchiest solution, but exists also in most of England (and only in France, England and USA). Actually there is not much difference with slate roof (it just depended on local availability of materials), both substitued thatched roofs.
The "Latin" half cylindrical tiles on rather flat roofs are typical for the whole Mediterranean area, but for some reason this solution was also maintained in Lorraine, including German speaking areas, and also in bordering districts of Germany, Luxembourg and (German speaking) Belgium! No satisfactory explanation has ever been given for this anomaly, other than Roman military presence bust have been considerable in that area.
"Germanic" steep roofs are prevalent of course in Alsace, with beaver-tail tiles, but also in the Alpine region. I know a small town in Eastern Bourgogne where "Latin, "Celtic' and "Germanic" roofs all are present side by side. Which I find mindboggling, knowing that carpenters guilds with different technical traditions were active on the same spot. (BTW Geneva is really the heart of Europe: some old mansions are definitely Italian style, the Calvin era quarter is absolutely "Celtic"/French, and there are typical Germanic antique farmhouses (just like in the black Forest or in Norway) nearby).
Oh, and I forgot: the large light pink area North of Paris is made of Germanic roofs with so called "pannes flamandes" (Flemish panes?), you know those large S-shaped tiles, which are standard all along the North Sea and Baltic shores (including New Anglia) up to Northern Sweden. The Dutch even built some buildings in that style in New Amsterdam/NYC.
