Life is Good! :
Here in northern Illinois, we might get a heavy snowstorm of 8" or more...but usually, our snow load isn't all at once (unless a blizzard swipes us like last year's Groundhog's Day).
I've got a peaked PVC roof on our tractor which is connected to the coop. I'm going to replace the tarp top with plastic panels from Menards - 12 feet long by 26 inches wide - I'll need 4 panels at $20 per panel - $80, not super cheap....but more durable for my situation. With your flat surface, a piece of plywood or even plexiglass would work well!
Have you thought about adding some 'skylights' of sorts - think cold-frames from the garden, but for the chickens to get some sunlight? I'm afraid the plywood would be so dark in there, the girls wouldn't want to go inside it. But if you have some cold-frames or even some old window sashes about...add those to make it 'brighter' inside too.
This is our tractor, now connected to the coop - inside a fully enclosed predator-safe run. (not pictured)

And yes, I too will be placing straw bales around the perimeter of my coop to help insulate it a bit more from low surface winds - but I'm going to wait until after the third week of freezes - by then, all the mice and local skunks/vermin should have found a good home (or will be dead). I'm not going to put it out too soon...not wanting to invite trouble!
Just some thoughts...
great thought and reminder.. I want to do the bales too.. great idea but yeah the first couple frost the vermin critters are gonna look for a warm new house for the winter I dont want that to be in my bales..
