Thanks for your reply and amazing work!!

Last comment I promise, "Is this set seasons compatible?"

Well it shouldn't matter since the area covered by the objects is inaccessible to sims, and the floor beneath them needs to be covered by floor tiles anyway.

Very last thing, and that's a fact: I made a request that you make and include a couple of windows that fit inside the "Round Dormer" perfectly both on one tile and on two tiles as in on one wall and in-between two walls, can it be done?

It can be done, but I just don't have the time or inclination to do anything more with this set these days. If you want to make an add-on you're free to do so, though.

When I asked if this set was "seasons compatible", I meant 3 things:
1) "When it rains, will the set keep your sims dry the same way that a roof built with the roofing tool in build mode will?"
2) "When the falling leaves come (If players have "The Sims 3: Seasons" installed) will the leaves pile on the set pieces just like a roof built with the roofing tool in build mode?"
And 3) "When the snow comes (Again, If players have "The Sims 3: Seasons" installed) will the snow pile on the set pieces, will the included windows get frosted with icy fog (if placed on walls without the roof pieces and without the dormers), and most importantly, will the roof pieces have icicles hanging from their edges?"

Get the idea now?

There's no need to be rude. I don't remember if these are seasons compatible, and it doesn't matter, because floor tiles already do these three things, and you need to have floor tiles placed beneath these objects.
