The answer to 'what causes downspouts' is that downspouts are an essential component of a home's roofing and drainage system. Downspouts are the vertical pipes that carry water from the roof's gutters down to the ground or into a drainage system. They play a crucial role in directing rainwater away from the home's foundation and preventing water damage.
Downspouts can become clogged or damaged for a variety of reasons, such as leaves, debris, or even animal nests accumulating inside them. Over time, the downspouts can also become dislodged or detached from the gutters, causing water to spill out and potentially cause damage to the home's siding or landscaping.
