Have been playing on a creative world recently with a friend and noticed the very last set of bricks titled "red roof tiles" which are actually red and white seem to have weird properties that do not match other roof tiles and are not viable as roofing material without extensive overworking.

They would not be able to over hang a roof like a typical house or temple..which is what I was going for in this case and it is very difficult to create support for them since the "flat" version does not allow side connections as support like other roof blocks do.
