All help gratefully received, sPK

Normal wood degrades to roughly 50% but.... Have a look here.

Where tarred wood items clip into normal beams they are "water proofed" just like the decorative beams.

I hope this helps your imagination and problem.

The only factor is whether or not the structure has a roof (a thatch roof, floor tiles don't count). Put a roof over the tower and it won't deteriorate.

My take on this would be to add a roof abover or underneath the platform where you stand on, so if at all, only the top floor will get damaged. There are other ways tho, like Placing the X-pieces into the walls I think. Or you could use the stake walls, they won't take damage from rain and have more health.
The version without a roof might be better for some people since roofing can easily block your sight, at least that's my experience.

Wood needs a roof. Stone not. So maybe a Stonetower is an option.

Weather will not degrade it more than 50%. You could just leave it like that, but keep the durability in mind if enemies start attacking it.

Angled wood pieces (the Xs and the triangle pieces) and stone floor do actually provide protection from rain for stuff below them.

Roof tiles are definitely the easiest bet though, you are correct on that.
