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

Contents

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 flat roof houses have load bearing walls?

Due to the triangular shape of all but flat roofs, the rafters or joists will run perpendicular to the roof ridge as well as to load-bearing walls. Use this clue to narrow down possible load-bearing wall locations.

## How can you tell if the roof is load bearing?

Step 1: Determine Whether a Wall Is Load-Bearing or Not

1. Check an unfinished basement or attic to see which way the joists run.
2. If the wall runs parallel to the joists, it’s probably not load-bearing.
3. If it’s perpendicular, it most likely is a load-bearing wall.

## Who can tell me if a wall is load bearing?

“If the wall above runs parallel or perpendicular to the joists, it is most likely load-bearing.” If you don’t have a basement – or if it’s finished – you can look at the joists in your attic or crawlspace, he says. … They can also be load-bearing.

## What part of a wood frame carries the floor and ceiling loads?

Floor joists are wood members or engineered wood products (typically the same size as the rim joists) which are placed on their narrow ends, spaced uniformly, and attached to the sill plate. The subfloor is attached to the floor joists, and they carry the floor loads to the load bearing walls.

## How big of an opening can you have in a load bearing wall?

Any opening that’s 6 feet or less can have just one 2×4 under the beam. This creates a bearing point 1.5 inches wide. Any opening wider than 6 feet should have a minimum of two 2x4s under each end of the beam.

## 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. The load from the roof is transferred from the rafters to the walls and down to the foundation footings. In addition, there may be one or more interior walls that support the ceiling joists.

## Can a 2×4 wall be load bearing?

A. There is almost no difference in the bearing capacity — the wall’s ability to support a compressive load, which is how most walls are loaded. 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.

## Do I need a structural engineer to remove a load bearing wall?
