The soffit corner is the area where the roof meets the wall, and it plays a significant role in protecting the building from the elements. Water can easily enter the building through this area, causing damage to the walls, ceilings, and other structural components. In addition, soffit corners can be a haven for insects, rodents, and other pests, which can further compromise the integrity of the building.
