How Dirty Gutters Can Cause Home Flooding

Many homeowners take gutter cleaning for granted. Keeping your gutters clean and free from debris is not just a matter of convenience; it can actually be the lifeline of your home. Difficult as it is to imagine, clogged gutters can cause your home to flood. So, how can clogged gutters cause your home to flood? Read on and find out.

Basement & Foundation

Basement flooding is a common problem. One of the major culprits is clogged gutters. When your gutters are clogged, they cause water to overflow the drainage and land next to your home's foundation. This area will be saturated with water. The resulting pressure from the saturated ground in this area will trigger constant expansion and contraction of your concrete foundation; causing it to crack. The water in this area will then seep through the cracks and cause flooding in your basement.

Such water can also cause the foundation to settle. The result: cracks in your foundation and walls and sloping floors.


Clogged gutters will cause water to seep back into the building through the roof. This water may damage roofing material. Over time, it will find its way into the ceiling and walls. This may cause flooding, structural damage, and electrical problems.

Other Effects of Clogged Gutters

Rotten Wood

Apart from flooding, clogged gutters can cause further damage to your home. They will cause the woodwork on your fascia board to rot. Eventually, this rot will spread to adjacent woodwork, such as the attic.

Sagging Gutters

If you continue to leave your gutters unattended, more debris will accumulate there causing the gutter to sag under the weight. Eventually, even the fasteners will come off. You may end up having to replace the entire gutter.

Insects and Rodents

Unclogged gutters will provide a safe-haven for rodents and insects. Termites, carpenter ants, mice, and God forbid, even snakes may use this as an easy route into your home.

Damaged Driveway and Deck

When rainwater is not going where it should, it lands on the ground, deck, and driveway. These areas are ill-prepared to receive such amounts of water. The result is a rotting deck, soil erosion, damaged landscaping, and a water-damaged driveway. Some kinds of flooding, such as those caused by Mother Nature, may not be avoidable. But others can absolutely be avoided. You don't want to damage your house over avoidable causes.

All you have to do is get your gutters cleaned regularly. If they are already damaged, consult a gutter installation expert for repair or replacement.
