What Happens When Your Gutters are Clogged?

When your gutters become clogged, water is unable to properly divert away from your home. Instead, the water will spill over the edge (or lip) of your gutters, which can lead to a cascade of different issues.
- Basement flooding: Clogged gutters lead to overflow and pooling of water around your foundation. This saturates the soil and allows moisture to seep inside the cracks, which causes basement flooding.
- Foundation damage: One of the most significant issues caused by clogged gutters is foundation damage. Water overflowing from clogged gutters can pool around the base of your home. Over time, this water can cause cracks in the foundation, which is expensive to repair.
- Roof damage: Blocked gutters can cause water to back up, which can damage roofing shingles and lead to leaks. Roof and flashing defects are the leading cause of water infiltration into homes, with clogged gutters being a major contributor.
- Pest infestations: Stagnant water and the moist, softened debris in clogged gutters can attract insects and pests like mosquitoes and termites. According to The Centers for Disease Control and Prevention (CDC), clogged gutters can be potential breeding sites for mosquitoes, which can spread diseases like West Nile Virus, Zika, and others.
- Ice dams: In colder climates, clogged gutters can exacerbate problems with ice dams, which form when heat from inside a home escapes into the attic and warms the roof, causing snow to melt and refreeze at the roof’s edge. If gutters are clogged, the water from melting snow and ice can’t flow through and divert away from your home. Ice dams can cause significant damage to roofs.
- Siding damage: Constant overflowing water can also lead to damage to the siding of a home, as well as the potential for wood rot.
- Health hazards: The US Department of Housing and Urban Development (HUD) reported that clogged gutters can be a health hazard, noting that “improper drainage, including clogged gutters” can lead to mold and mildew growth.
- Safety hazards: In winter, clogged gutters can cause icicles to form, which can be a hazard if they fall and hit a person or even a pet. Moreover, the added weight of debris, water, and ice can cause gutters to pull away from the house or collapse.
- Landscape damage: Overflowing water from blocked gutters can lead to soil erosion and damage plants and shrubs located directly beneath the gutters.
These issues not only impact the health, safety, and appearance of your home, but they can also get expensive. The average cost of repairing water damage due to clogged gutters can range from hundreds to thousands of dollars, depending on the extent.
According to research from HomeAdvisor, the average water damage repair bill in 2022 was $3,600.
The best way to avoid these costly problems is to check your rain gutters (or eavestroughs) frequently and pay close attention to the following important signs.
Signs That Your Gutters are Clogged
- You Spot Animals or Pests Around Your Gutters

If you are noticing animals or pests scurrying around your gutters, this can be a big sign your gutters are clogged. Birds and squirrels find gutters to be a convenient place to make a nest, and those nesting materials can easily block your gutters.
- Water is Spilling Over the Sides

If you notice water spilling over the sides of your gutters, it’s a sure sign you have clogs. The obstruction can force water over the edge of your gutters and down your siding, where it can infiltrate your walls and foundation, leading to expensive water-related damage.
So if you ever notice your basement flooding during a rainstorm, blocked gutters may be to blame, causing water to divert into your home’s basement.
- Sagging Gutters

Sagging gutters are another common sign that your gutters are clogged. The weight of the leaves, shingle grit, pine needles, and other debris can cause your gutters to bend and sag. Unfortunately, clogged, sagging gutters will be ineffective at carrying water away from your home.
If enough debris remains in your gutters for long periods of time, the excess weight will begin to wear on the gutter itself. Your gutters can even begin pulling away from your home, causing even more issues and homeowner headaches.
- Stains on Your Home’s Siding

Any signs of staining on the siding of your home is a sign that there’s standing water in your gutter system. Stagnant rainwater could end up causing costly damage to the fascia boards behind the gutters and on the shingles of your roof.
- Plant Growth

Have you ever looked up and noticed a garden in your gutter? This is an obvious sign of clogged gutters. Seeds can accumulate in your gutters along with dirt and debris, allowing a gutter garden to form.
Plant growth is a glaring sign that your gutters need to be cleaned out. Foam gutter guards are notorious for encouraging plant growth inside your gutters.
- You Don’t Remember the Last Time You Cleaned

If you can’t remember the last time you climbed the ladder to clean out your clogged rain gutters, it’s likely that they’re in need of a serious cleaning. Your gutter system should be cleaned out each season to ensure your home is properly protected against expensive water-related damage that can result from clogged gutters.

How to Keep Gutters from Clogging

The single best method to avoid clogged gutters (and the damage they can cause) is to prevent your gutters from becoming blocked in the first place. In terms of how to keep your gutters clog-free, there are a variety of options.
- Install gutter guards to keep out debris. There are various types of gutter guards, from foam filters to perforated metal that allow water to flow while blocking pine needles, leaves, and other debris from entering your gutters.
- Use gutter brushes or rubber strips that sit inside the gutter to direct water under them while preventing buildup on top.
- Regularly clean out gutters every spring and fall, more often if you have overhanging trees. This removes debris before it accumulates.
- Make sure gutters have proper slope and pitch to keep water moving efficiently. A slight tilt (about ¼ to ½ inch for every 10 feet of gutters) allows proper drainage. For long gutter sections, a pitch from the middle of the gutter towards a downspout at each end works best.
- Check that all downspouts and elbows are clear of debris so water can exit the system freely. For more read “How to Clean Gutter Downspouts.”
- Trim back overhanging tree limbs to prevent leaves from accumulating in and creating clogs inside your gutters.
- Avoid growing climbing vines on your home which can shed debris into gutters.
- Consider installing larger gutters that are less likely to get congested. (However, it’s still important to keep them free of debris.)
- Divert rainwater from downspouts away from the home’s foundation.
Along with regular gutter maintenance, these methods are your best options to eliminate gutter clogging issues.
