If rain falls from the roof because there are no gutters, the water causes massive erosion, dragging more and more dirt away every time it rains. This causes the carefully sloped landscape to wear away, allowing runoff to flow into your home instead of away from it. Erosion also causes the base to settle. The gutters control the water that reaches the roof and direct it to a single flow that moves away from the house.
Without gutters, water runoff may build up around the house, enter the foundation, and cause water damage over time. Gutters cannot effectively ward off water unless they are cleaned frequently, and damaged gutters can cause more damage than not having gutters, since they can cause water to accumulate along the roof. In addition to protecting the roof and the overall structure of your home, rain gutters also prevent soil erosion and protect your garden beds. With rain gutters, rain will simply flow from the roof, dragging the soil away every time it rains, causing soil erosion.
And if you have planters built next to your house, soil erosion will cause the pool of water to drown out your plants and flowers. If your home just suffered significant damage from a storm, then a torn rain gutter is probably the least of your worries right now. This is one of the main reasons why gutters exist to prevent water from damaging your home by diverting rainwater from your home.
