I am about to replace a 28 in. door in my house with a new, wider, 32 in. pre-hung door and install a new, properly sized header. The door separates the upstairs hallway from the unfinished attic space. The wall that the door is in supports both the hallway ceiling and the roof. The wall has a single top plate.
I was planning on building a simple support and putting it on the hallway side of the door but then realized that would do nothing to support the roof. So I thought about building a second support to put side on the attic side of the door, but that starts to feel like I'm over-doing it. Considering that the present header is a couple of 2x4s laying flat and that has been fine for the last 90 years, maybe I don't need a temporary support wall at all to do this work. Any thoughts?
