How do I make a screened porch using an aluminum or tin roof?

I would like to have a screened in porch on my patio a tin roof which faces the lake I want it to be simple and southern LOL like Tennessee ! I want a tin or aluminum roof as I need to keep my furniture dry as much as possible it gets very hot here we’re west of Palm Beach Florida so you can only imagine the heat! We are on the lake running into the Okeechobee river so we are west of Palm Beach ! A simple design about 40 ft by 10 ft as I already have concret with pavers on top of it. The rest we can handle on our own as we watch fireworks from our house and it’s just a fun place to be ! Does anyone have suggestions on this job that would be a DIY? Sincerely Gerridag @
