A few years ago I built a wooden deck off the back of our house which is pier and beam construction. I built the deck with the plan to add a covered porch in the future which is now. I curious what people's thoughts are on porch covering material. I've placed my rafters at 16" centers and have about a 1.2:12 pitch. Overall porch coverage is roughly 8'x16' Should I use corrugated material, treated plywood, other?
Thanks
