Weep holes are crucial in masonry construction because they allow water that accumulates within the wall system to escape. In masonry, moisture can penetrate the wall due to rain or humidity, and without escape routes, this water can lead to various issues such as mold growth, deterioration of the masonry materials, and structural damage over time. By incorporating weep holes at regular intervals at the base of a wall, any trapped moisture can drain out effectively, which helps to maintain the structural integrity and longevity of the masonry work.

Other options focus on aspects that do not directly relate to the primary purpose of weep holes. Enhancing aesthetic appeal is not the functional intent of weep holes; instead, they serve a practical purpose. Supporting vertical structures is related to the load-bearing capacity of the wall rather than moisture management. Ventilation is important in masonry construction but is typically addressed through separate design elements, rather than through the function of weep holes specifically.
