Removing a wall on a hip roof.
Go downstairs or to the basement and see where the wiring plumbing venting etc.
When you remove a load bearing wall you need to create a temporary support to bear the weight of the ceiling before removing the wall which will remain until the beam is fully in place.
Watch this video before.
There are no gable ends on a building with a hip roof.
When you have your eye set on removing a load bearing wall you may be thinking of removing the whole wall to turn two rooms into one or maybe just removing a piece of the wall to widen a doorway or create a pass through between rooms.
In hip roof designs all four exterior walls support the ends of roof rafters so all exterior walls bear a weight load from the roof above them.
A hip roof is a roof in which the roof slopes upward from all four exterior walls to meet at a central ridge.
Adjustable steel columns also called lally columns or jack posts are the quickest and most effective way to add supports.
There are two ways to accomplish this.
Lay a strip of 2x4s on the floor run another doubled up strip across the ceiling held in place with nails or screws then jack a pair of steel.
Just to be on the side of caution i would install an 8ft 4x4 directly centered under the splice with lag bolts and remove the vertical.
The wall you are wanting to remove is not a bearing wall by looking at the framing in the attic and the roof lines of the house.
