I get that, But I don't remember any Single viking being capable of all of the ♥♥♥♥ we can do in this game, a Floor/roof tile shouldn't be a huge ask. (I mean a single viking by himself doing all the smithing, cooking, building, harvesting, etc.)
It also would just be nice to be able to build forts that don't have decaying walkways all the time, Don't get me wrong, I understand that they want to keep an authentic feel to building, but I hate that I'm so limited in my creativity because of an arbitrary need to Have all roof's be angled. Let me spend resin(or beeway/tar like Polaris said) and wood to make a Treated floor panel and let that operate as a roof as well, or something. I wanted to make my hall a three story building that the third story was like a building on top of the building, that then had a balcony to walk on. I know vikings didn't roll like that. But it would be nice to feel my progression in my buildings as well as my gear and crafting stations.
