Do I need membrane under my steel shingles on a gazebo?

Hi Everyone, I am currently building a large gazebo and I have settled on steel shingles (https://idealroofing.ca/en-us/products/roofing-and-siding/wakefield-bridge/ ) My rafters are made of 6x6 PT, and on it I will lay down 3/4 plywood for sheathing. My question is for waterproof membrane, is it a must even on a gazebo? Or is it really only for houses which are closed and heated? I appreciate all the help! submitted by /u/Yorkmiester [link] [comments]
