Which houses are weatherproof in Seasons?

Most people now realise that buildings with CFE-shaped roofs aren't weatherproof in Seasons. Snow and rain will lie OK on flat floor/roof tiles, but not sloping ones.

Many of my recent buildings with CFE roofs are weatherproof, and the ones that weren't I've now made so. The one exception is Tiger's Nest - which is such a pity!!!

The explanation is that as you can see from my tutorials, for my Japanese roofs I include an attic space, and when this has - or is given - a floor, the snow and heavy rain settle lightly on the attic floor, leaving Sims snug and content in the building below.

But Tiger's Nest is so complex and has so many levels that I had to give 2 large rooms a single sloping roof, without any attic space. I'll see what I can do with it later on! :)

My earlier buildings can also mostly be weatherproofed, and I'll be doing this over the next week. The starships and some parts of the Biospheres can't be weatherproofed, I'm afraid. :( Oh well. ;)
