I had a 7' x 16' lanai built with 2x6s. I wanted it dry underneath. Using roofing screws I attached light weight pvc roofing panels under the decking. Being short and 'older' I could only handle the 4x8 panels but 4x16 are better - if you have a way to get them home from HD.
Make sure to give them a slight slant so water will drain off. I put gutters on the edges and hung a chain to channel the water.
This is a good temporary solution that can always be removed. Later I replaced the 2x6 decking with plywood and used a special two layer coating to seal it.
