I am replacing a 4 ft doorway in a load bearing wall with a 4 ft pocket door, which necessitates replacing the header in the wall with an 8 ft header (4 ft of door + 2x 2 ft of door pocket).
The wall is parallel to the joists, but the house has a hip roof. The wall is an interior wall only because of an addition that was added onto this side of the house -- this wall used to be the exterior wall. As a result, the wall does bear the load of the roof hip. However, since the wall is parallel to the joists, I cannot simply support the portion of the wall above the header by supporting the room ceiling.
How does one support the wall temporarily so that the header can be changed?
