If there is chances are the walls are load bearing.
Residential roof load on walls below.
So an 8 foot tall wall weighs 8 ft x 16 pounds ft 2 128 pounds per lineal foot.
Load limits on the roof of a building.
Generally when the wall in question runs parallel to the floor joists above it is not a load bearing wall.
Roofs are under a lot of pressure.
If the wall in.
Loads are contributed to the lower header by the roof upper walls and 2nd floor system.
The architectural graphic standards lists the weight of an exterior 2 6 wall as 16 pounds per ft 2.
For example a gable end truss may be designed with support members that transmit the roof weight load outward to the side walls allowing the end wall directly below it to have breaks or openings in it that would otherwise be impossible.
If the wall in question is on the second floor look to see if there is a wall in the exact same place on the floor below.
However there are cases where a bearing wall is parallel to the joists.
But if the wall runs perpendicular at a 90 degree angle to the joists there is a good chance that it is load bearing.
