I tired of getting wet when grilling on the deck. I am looking to build a shed roof design roof to cover my grill and me when grilling. The area will be 8 x 8 or less. I plan to make it tall enough so I can use corrugated fiberglass panels for the roof but I am not locked in corrugated panels. Any suggestions on how to best vent? Something passive. I am not looking at a high dollar electric range/grill hood.
