Description of issue:
In the default MCWRoofs, the roof blocks block light from passing through.
The Compat roofs allow light to pass through, meaning that lighting will be different from one building to another.

Expected:
Both roofs should block light from passing through.

Actual:
BYG Compat roofs (eg: Redwood roof) allows light to pass through. I've attached an image of this below.

I've tested this with a few different materials just to confirm that it's not just that one block, and it seems to affect multiple, if not all roof blocks. This also applies to your BoP compat roofs too.
