Quick Answer: How do you know if a flat roof is a load bearing wall?

Generally, when the wall in question runs parallel to the floor joists above, it is not a load-bearing wall. But if the wall runs perpendicular (at a 90-degree angle) to the joists, there is a good chance that it is load-bearing. However, there are cases where a bearing wall is parallel to the joists.

Do single-story houses have load bearing walls?

In a single-story home with a stick-built gabled roof, the bearing walls are the exterior walls where the rafters rest.

Can a 2×4 wall be load bearing?

Bearing capacity is a function of the footprint area of all the studs in a wall. For example, a 4-foot section of wall would have three 2x4s, but only two 2x6s.
