Abstract: An articulating downspout assembly for a downspout system of a building has an elbow component and an end component each having an integrated or integral configuration that cooperatively join with each other to form a hinge. The hinge allows the end component to pivot between a prone position and an upright position. In the upright position the end component is at an angle relative to the elbow component such that a downspout extension section coupled to the end component leans toward and/or against a vertical downspout portion of the building's downspout system. This prevents the end component and thus the downspout extension from spontaneously falling (pivoting) back to the prone position. The integrated configuration of the elbow component is characterized by one or more configured slots while the integrated configuration of the end component is characterized by one or more configured tabs.
