Waterproofing under deck – extending metal roof panels?

Hi. I’ve seen posts about using metal roofing under a deck to create some dry space. I have a 16 ft long deck that is only 4 foot wide. The patio underneath is much wider. I wasn’t planning to add gutter and just let the run off fall on the extended patio. However, the deck is quite high and I’m concerned 4 ft won’t give me much dry space underneath, considering there will probably be some rain blow in. Can I extend the roof panels beyond the 4 ft and if so, how far? Concerns that I’ve thought of are leaving a sharp metal edge exposed but I doubt it would be much of a safety issue as it is high up but I would feel better with a solution; looking a little weird from the top deck but I think I could live with that; no support for the extension but I’m thnking it would only be an issue if something fell on it? Any and all advice, thoughts and considerations greatly appreciated!

Yes, you can do that. Just build a light frame under the deck and sheet it with roofing metal. You can make it extend out as far as you like.
