The rainwater that falls on a roof must be managed so that it falls off of the roof in a controlled manner. This is so that it does not get too close to the foundation and also so that it remains clear of falling over the threshold points for entering and exiting the structure. In order to accomplish this gutters and downspouts are placed along the edges of the roof to capture the runoff.
But there is an upgrade option: Rain Chains.

Rain chains fulfill the same purpose as downspouts but with some added benefits.
Rain chains are far more attractive than your conventional downspouts.
Because they are designed to channel the water straight down from the gutter hole, they don’t need to be routed back closer to the structure on their way back down to the ground. Because they are already (typically) set apart from the structure at the point of exit from the gutter, they don’t need to be carried away from it such as in the case of a downspout that is attached to the side of the structure.
So, rain chains ultimately not only fulfill the same functions of the conventional downspout, but they also have the added benefit of accenting the overall look of the curb appeal.
