Okay, here's the deal. I'm moving into an apartment that has a door that leads out onto the sloped roof of the first floor. It's intended to be used as a patio, which is great, but the roof is sloped a bit too much to be able to feel safe. So I want to level it out, and can't seem to find any information on what to do. I don't think I can nail into the roof, as it looks like a tarrish membrane that is most likely waterproof. On either side of the roof is a fire escape, would it be possible to anchor into that?
Here are some shots of the deck
Has anyone encountered the problem?

That should give you an idea of what I want to do, the red part is what I want to build.
