Roofing

The answer to 'why is my downspouts water stains' is that downspout water stains are typically caused by mineral deposits or algae buildup from water draining through the downspout. This can happen over time as water flows through the downspout, leaving behind residue that discolors the surface.

The stains are usually brown, green, or black in color and can be unsightly. Common causes include hard water, environmental pollution, or organic matter in the water. Fixing the issue may require cleaning the downspout, adjusting the drainage, or replacing the downspout if it's severely damaged.
