Leaves and twigs can build up over time and clog your home’s gutters and downspouts. You may also notice sections of the gutters are leaking, are sagging or have separated from the house. Gutters that aren’t working correctly can allow water to damage your roof, foundation and more.
If water doesn’t flow through the gutter system, it can collect under the roofing and damage shingles, underlayment and decking. Water under the roofing can also leak into your home, damaging ceilings, walls and floors, and allowing mold growth. In winter, water trapped in gutters can freeze, forcing ice back under the edge of the shingles and resulting in leaks when the warm air under the roof melts the ice. In addition, the weight of debris and accumulated water in a clogged gutter may cause it to pull away from the roof, creating gaps. Water can then cause damage and rot under the fascia that runs along the edge of the roof.
If clogged or damaged gutters allow water to reach your home’s foundation, the water can soften the ground, leading to cracks in the foundation. A damaged foundation can create more problems inside, including damaged floors, warped door and window frames, and cracks in walls. The water can also reach your crawlspace or basement, leading to more moisture and mold problems.
While poorly maintained gutters can cause expensive problems, you can avoid damage to your home, and the cost to repair it, if you follow a couple of simple steps.
- Clean your gutters at least twice a year — once in the spring and then once again in the fall.
- Check the gutters before and after heavy rain showers to make sure they’re still clear.
