I'm holding back on the smartass comments, but it's gonna be tough on this one.
There is nothing that you did here that even comes close to being a "roof".
You must keep the water out 1st and then think about building a deck on top of it that doesn't damage what you used to keep the water out.
What's your budget for this project?
There are several ways to approach this: There are paint on with mesh coatings, membranes, and metal, going from easiest to difficult.
