Carport roof: from flat to sloped

I have a carport that needs some work. The roof leaks and has been for a while. It is a flat roof and the roofing material is peeling up and coming off. A bunch of the framing for the carport itself also needs to be replaced as well I am sure as the plywood. Thinking this is going to be a start over.

I am wondering about changing it from a flat roof to a one direction sloped roof. Idealy I would like to able to put a metal roof on.

What I am wondering about is how to frame the new roof up. I have vinyl siding on the house, and would like to leave that how it is. There is a ledger board attached to the house (might also be in need of replacing will have too see). I would like to keep the height of everything around the same as it currently is. So question is can this be done? Can I taper my joists? Or is there a better solution to achieving this?

 

How is the current carport supported? pics would be nice

You will either loose headroom on the side of the carport or you'd need to raise the end that's attached to the house.

 

I can try and get some photos. The carport is currently supported by 4 4x4 posts on the non-house side.

 

It would be especially helpful to know/see how it's attached on the house side.

 

Some helpful information.... How-to-insert-pictures

 

sorry for the delay on photos - was not at the house for a few

 

Looks like you have just under 2 feet of space between the existing roof and the windows above, which is ample space to put some 2x6 sloped rafters at a 2:12 pitch for example. You'd only need to remove the bottom course of siding.

 

So would need to move the board that is attached to the house currently higher? Yeah is a bit under 2 feet to the edge of that window.

 

If you reuse the existing boards they will effectively be a little shorter - less overhang on the 4x4 side.
