Good day, I live in Ontario Canada - we have very hot days in the summer but the winter can be cold and harsh, with alot of snow but not regularly. I'd like to design my deck, which sits 6 ft. above the ground, I'd also like a covered roof, but it can be expensive. I was considering to not cover the deck, but rather use a pergola. What's the best solution to have a deck, even with a partial covered roof considering the snow might be heavy if we choose plexiglass or fibreglass to fill the slats? I'd like the rain protection...or something removable during the winter months other than tough, awning material? Thanks.
