It is possible to obtain "used" terra cotta roof tiles in various styles. They still are fairly expensive. I used a green French style. (I would provide a picture of the final result if I could figure out how to do it. Perhaps someone can explain it to the "dummy".)
If you are interested in "used "terra cotta tiles I can send you some information on where to obtain them. You could also use concrete roof tiles which I supect are a less expensive.
