I am buying an older house and someone made the porch into living space, but the roof over the porch is almost flat. It has sagged a little and now is leaking. I wondered how to tie new roof rafters into the original house roof to raise the pitch.

This is not a difficult project, but will require dismantling the old roof and installing a rafter support and flashing at a higher position on the wall where the new roof will be attached. Things that constrain the height of the new roof, or complicate its design, are windows or other obstructions on the wall.

To do this, You should cut or remove the siding up to the level where the new roof will attach. You will need to add flashing that goes behind the siding and over the new roof. Attach a board horizontally at the new roof height and cut rafters to extend from there to the front wall and eaves. Use adjustible rafter hangers to attach the rafters at the house, and hurricane clips at the top sill on the addition. Frame the sides, and apply siding, roof sheeting, roofing, facia and all that good stuff.

Since we are dealing with generalities here, you may have more questions. If you can reply with the total rise of the new roof and horizontal distance of the addition, perhaps we could be more help.
