And here it is! My reaction on Frenchbadping's work!
On this content you can download all of his roof-textures and the gutter models.
Why you shouldn't just download it on the original node?
As you will have to download 2 separate files, while they both carry the same purpose, to enhance roofs.
I've packaged and configured it as FrenchBadPing didn't managed to do so, on a simple way.

There is a side-note to the license:
- You can do with the files what ever you want, as long as you won't change the license (which is and should stay public domain).

Have fun using them!
