IIRC the Rottenburg roofs don't actually have any real displacing from their original brush form, which makes me think that they're only made into disps to get softer lighting.
I'd look at Dustbowl's metal shack roofs for inspiration. There's little subtle variations in the roof lines like this. While I think there could definitely be a bit more splitting happening on this particular roof, the important part is that it's subtle, and the shape still reads as a sharp line from even a short distance. I don't think yours does.
