I use the clear corregated panels from Lowes. $20 you can cut them with scissors, attach with screws and they last for YEARS. I am on winter 5 with mine.I think it looks great! I was definitely planning to cover the sides with plastic tarps as well (i really like the idea of getting a few of the disposable shower curtains at the 99 cent store because they are nice and thick but also very clear) Sounds like the consensus is "Stop being lazy, build a proper roof" i think deep down i knew this but was looking for someone to tell me there was an easier way lol! thanks!
