Roof Load Bearing Wall

A wall that is set directly over one of those beams is probably not a load.

Roof load bearing wall. Every house uses load bearing walls to stabilize the structure and support the weight of the home above. Using this technique you ll get a better idea of the location of the load bearing walls in your house. Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load. Often these load bearing walls are roughly near the center of the house because the center of the house is the farthest point from any of the exterior walls.

The distance in this case is 12 ft 2 ft 14 ft. By contrast a non load bearing wall sometimes called a partition wall is responsible only for holding up itself. Foundation wall gravity and soil lateral loads headers girders joists interior load bearing walls and columns footings gravity loads exterior load bearing walls and columns gravity and transverse lateral load 3 roof rafters trusses and beams. Rafter spans can be extended slightly beyond what the rafter tables suggest when there is a cantelever extending beyond the supporting wall.

Engineered roof truss systems may be designed to eliminate the need for load bearing walls or change where the bearing walls are located. The exterior wall and the headers within will carry all loads from the mid point of the house between the supporting walls to the outside of the house including the roof overhang. There s a good chance this wall is load bearing especially if it runs parallel to a central basement support beam. If a wall is located on the ground floor go down to the basement to observe the ceiling beams.

The roof trusses are too long to span the whole house so the load bearing wall runs down the center of the house to support the trusses at the perpendicular intersection in the middle. 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. Ceiling joist span use this table to determine the maximum lengths of ceiling joists based on species of lumber joist spacing and joist size. Even without a second story the roof weighs a lot and load bearing walls bear most of the.
