You still need to indicate the pitch, the roof sheathing, and the shingle weight.
Usually, a load bearing wall will be perpendicular to the roof ridge.

All exterior walls in a home are load bearing. The exterior walls on the gable end of your house do not bear much load, but the walls that the hip of the roof bear on carry your roof and ceiling joints. Interior walls are another story. Usually in a smaller one story home there is a wall that runs the midspan of the house that is load bearing for your roof and ceiling joints.

38 feet longIt is not possible to give a definite answer without more detail. The construction and type of roof will determine the load (weight) bearing on the beam, and factors such as wind load and earthquake load, and the way the roof bears on the beam (truss/point load/distributed load) will all affect the sizing.

That is not a simple anwer. It depends on the roof design and how many, and where the load points are, and the material of the beam(wood, metal, composite). See a structural engineer.
The recommended patio roof beam span according to the patio roof beam span table is typically around 10-12 feet.
In plank and beam framing, the load on the roof is transmitted to the foundation through a series of structural components. The roof's weight is first carried by the roof beams, which distribute the load down to the floor joists. These joists then transfer the load to the supporting beams or walls, ultimately directing the force to the foundation. This system ensures that the structural integrity is maintained and the loads are evenly distributed across the foundation.
The beam supporting the roof would carry a live load due to the weight of the accumulated snow. This load is variable and can change based on the amount of snow present, which can exert significant downward pressure on the structure. Additionally, the beam must also account for the dead load of the roof itself, as well as any other permanent fixtures. Proper structural design is essential to ensure the beam can safely support these combined loads.

The size of the beam needed to span 10 feet for roof support depends on various factors, including the type of material (wood, steel, etc.), the load it will carry, and local building codes. For a typical wooden beam, a common choice might be a 2x10 or 2x12, but calculations based on specific load requirements and spacing are essential. It's advisable to consult a structural engineer or local building codes to determine the exact specifications for safety and compliance.

A load-bearing support beam in a building structure is used to carry and distribute the weight of the building's floors, walls, and roof to the foundation. It helps to ensure the stability and structural integrity of the building.
Support the load whatever it is, roof, second floor, generally by putting a temporary beam under the joist inside of the existing wall, tear the wall out and put in a beam to carry the load. How big the beam needs to be depends on what the load is and how long the span is. Support the beam on each end and remove the temporary beam. These are the general steps, each project is going to be slightly different and has to be figured on it's own.
It depends on the roof load and the actual clear span. Off hand, I would guess htat you haven't given this much thought. A rule of thumb for a steel truss is one inch per foot of span or in your case 40 inches. If you want to use a steel I-beam, you can get that from a good municipal library from the steel beam institute, but you are going to need a crane to place it. Dieter in Cincinnati
