The valley gutter serves as a crucial flashing element designed to facilitate the effective collection and drainage of rainwater from two distinct roof slopes that converge in a region known as the basket. This feature is especially prevalent in metal roofs characterized by low pitches, typically less than 10 degrees. The primary purpose of the valley gutter is to ensure the secure drainage of rainwater into the eaves gutter, preventing any moisture from infiltrating the underlying substructure. This design proves particularly valuable in maintaining the integrity of roofs with minimal pitches, safeguarding against potential water damage and ensuring the efficient disposal of rainwater without compromising the structural integrity of the building.
