However a house with a hip roof structure suggests that all the exterior walls are bearing walls.
Hip roof bearing walls.
A hip roof is a kind of roof whose slides come with a gentle slope and it tends to slope down toward the walls.
Load bearing walls are those walls in a structure that support the weight of the structure above.
The exception would be in the case of a hip roof were ceiling joists often change direction at each end of the house and a wall is run crossways to support the inside ends of the joist the ceiling joists appear to change direction directly above one of the walls.
This kind of roof doesn t have any vertical slides or gables.
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.
Any wall on all floors directly above or parallel to a basement beam typically wood steel i beam or a basement wall must be considered by a layman as directly load bearing.
Stair well openings are also typically load bearing points.
Hip roofs require an extremely complicated system of trusses and rafters.
A bearing wall will run in the same direction as the ridge of your roof.
