Proud New Yurt Owner- Needs a New Cover

[InspireOut]

Hello Yurt Enthusiasts,

I am so honored to finally post in this amazing community as my wife and I are Tiny House dwellers and have dreamt of a yurt for quite some time. We found a used one on Craigslist and jumped on the opportunity to purchase a 16 footer. I am not sure if it is homemade as their is no identifiable markings of a manufacturer. The ring, rafters, cable, lattice,

insulation

, door, flooring, beams, and pillars are all in solid shape, however the covering, which is made from used billboards is brittle and needs to be replaced. My wife and I are both middle school teachers, and are interested in taking on the challenge to fabricate covers and save a few dollars.
First, we are in the foothills of Northern California and it is possible we may be putting this yurt at snowline. Can a 16 foot yurt with 2x4 rafters support a snow load? If so, what are we talking?
Second, if snow or rain is in the cards, is the vinyl coated poly fabric the was to go? If so, it looks like buying a roll of 100 yards may be cheapest (https://www.tarpsnow.com/18-oz-vinyl...yard-roll.html), does it make sense to use the same thickness of the walls and roof cover?
Lastly, I was hoping to get a little input on whether the epoxy for this fabric is easy to use, and if adhering this way is doable by a mildly skilled enthusiast like myself. I appreciate any an all input. Thank you!
