Terracotta shingle roof roof that can have size and shingle tilt via parameters.
Details can be found on my blog:

Settings
Size: The size of the entire build is controlled by two variables lenth and width. The spelling may be not correct but these are their names.
NOTE: use lenth=9; and width=4 as maximum, I experienced some unstable behavior if the variables are set bigger!

Terracotta shingles
This is created by a product of difference of two cylinders. The size, length and pitch of the terracotta singles can be controlled individually. For pitch I used 6 degrees that is set in shingle_tilt variable. The keyword OR stands for outer radius, IR stands for inner, and h is simply the length of the cylinder.

Once you decide to compile it may take quite a while to get an STL file. It will get seemingly stuck at two part somewhere between 60 -70% and 90-100%. Have patience!
