Are you making a snowy themed map?
Do your rooftops lack nice fluffy prop snow?
Is your map in late beta?
If you answered yes to all three of those questions, boy do I have an offer for you!
I will make bespoke snow rooftop models for your map
Once your map is in late beta (as in, you're not going to be changing the rooftop geometry), post here if to let me know you're interested and when I'm available we'll talk on discord or steam about specifics. I'm currently neck deep in moving house so I might not be able to start on any until mid-late November, but after that I hope this will be an on-going offer
Here's examples of snow I've made for Snowplow:
