Replace balcony railing, How to attach to the metal roof etc.

[fender stratocaster]

I'm thinking of replacing the iron railing on the balcony with one made of wood, maybe three posts in front and two attached to the wall just like now. I'm considering whether to settle for two posts being attached to the wall and the other three standing loose? Or how should I attach them to the metal floor on the balcony. I don't want any leakage. How would you have done it? I could make a deck that the posts sit in but then the deck would need to be attached to the wall, which makes it heavy, and it feels like everything could just sail away

Is it just current on the plate or is it attached to the plate and is it tight there?

I think the previous writer wanted to formulate a question. Tip: A question mark looks like this: ?
To TS:
Do you want to use it as a balcony? I actually think that the current iron railing looks quite nice and fitting. Sleek and fine. A wooden railing can easily become clunky.
Penetrating the sheet metal roof is not something to play with. Even if it feels tight at the moment, it will likely leak after a few winters. A sheet metal worker would probably have folded up the sheet against the wooden post, but that really only works with new construction.
If you still want to change, please don't throw away the iron railing. There are many who want one like that.

Now TS does not intend to keep the railing but is asking what they can do to switch to a wooden railing. Hence my question in plain everyday Swedish that TS is likely to understand.

A loose balcony railing is probably not recommended. Use post shoes designed to be attached from above like these:

Seal the screw holes and around the entire post bracket with Sikaflex or similar. Since the roof extends beyond the wall, move the posts a few cm from their current position so the brackets will be outside the outer wall and any leakage will also occur on the outside of the house and not inside the wall.

I'm considering whether to settle for having two posts attached to the wall and the other three standing freely? Or how should I attach them to the metal floor on the balcony.

How did you solve the attachment issue?
