I live in a one-story house with a cathedral ceiling in the great room. The front door is inset between the garage and the great room. The garage and front door share the same roof slope and slant, but the great room's roof has a perpendicular slant with a steeper slope.
I would like to move the front door over and close in the inset area as living space. But then the roof slope will need to be adjusted. Can I put a new roof over the existing one so I can minimize the damage to the inside of the house?
