Can anything be done about the blocky edges of gabled roofs?

[SeaWarriorSon]

Is there anything can be done with wood or thatch roofs?

I know chiseling slate or ceramic roofs can make gables look better (especially with the support beams), but I'm wondering about the early game thatch/wood roofs

Aside from chiseling hay or wood blocks there isn't much you can do in vanilla.

If you're open to using a mod though I can't recommend the VS Roofing Mod, https://mods.vintagestory.at/show/mod/30143, enough.
