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. A house without gutters allows water to fall directly from the roof to the foundation.
Any small crack or pore in the base can let water enter the basement, causing flooding. With gutters, water can be effectively directed to a drain and away from your home, preventing more devastating and costly damage to your living space. Did your house have gutters and, over the years, did you lose them? Decomposition, rust, aging, snow and ice gutters can fail for many reasons. If your house had gutters and now gutters are a distant memory, your home is vulnerable.
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.
