Why Your Gutters Are Leaking and How to Fix


Ever notice water spilling over the sides of your gutters or strange stains on your siding after a good rain? You’re not alone—and it usually means one thing: your gutters are leaking. While it might seem like a small issue, those leaks can quietly lead to much bigger problems—think foundation cracks, rotting wood, and even mold creeping into your home. But don’t stress just yet! In this post, we’ll walk through the most common reasons gutters leak and, more importantly, how you can fix them before they cause real trouble.

1. Clogged Gutters

The most common cause of gutter leakage are clogged gutters. When leaves, dirt, and other debris accumulate in your gutters the water doesn’t have a clear path to travel through and leave through the downspout. Clogs cause water to spill over the top of your gutters, run down the sides of your gutters, or drip down the side of your home. To check if a clogged gutter is the problem of your leakage, you simply need to look inside the gutters to identify potential blockages. Of course, if you’re not comfortable doing that yourself, give a professional team of gutter repair and installation specialists a call. 

2. Separated Joints

Gutters and downspouts are connected via joints and over time these joints can hold debris and water causing blockages for wain water to escape. This build-up can actually cause the joints to deteriorate and cause further issues. If the damage isn’t too bad, you can use caulking to fill the separation to once again allow water to flow freely. However, chances are the joints will need to be replaced. 

3. Gutter Sloping

Gutter sloping is an art and a science, and if it’s done incorrectly, or your gutters have sagged over time, water can pool in the gutters. Pooling water can cause gutter rust and deterioration, leaving weak spots for water to leak from. Luckily, if your gutters are improperly sloping, and they haven’t started deteriorating you don’t have to completely replace them; just contact the professionals to properly adjust your gutter slope. 

4. Loose Gutters


Having gutters that aren’t fully secured to your house can often make it look like the gutters are leaking, however, what’s actually happening is the water from your roof is missing the gutter completely and falling in between the gutter and the house. The solution to this issue is to reattach the gutters to your home’s fascia – creating a tighter seal for water to run off. Of course, further repairs may need to be completed if your home’s fascia has deteriorated, but that analysis will be made once you’re closely looking at the gutters. 

5. Holes and Gapping

If your gutters have holes or gaps, the issue is a little easier to identify than some of the others on our list. After all, if there is a hole (or several) the water will escape in small sections, unlike the water leakage from having loose gutters or incorrectly sloped gutters. The solutions for repairing gutter holes and gapping are varied, but your specialist will either repair the holes or suggest a replacement if the repairs would not be successful. 


If you’re noticing leaking gutters, you need to address the issue sooner rather than later.  Let’s talk about what happens when they go unchecked.

What Damage Can a Leaking Gutter Cause

Foundation Damage

How Water Accumulates Near the Foundation

When gutters are clogged or your yard doesn’t slope away from the house like it should, all that rainwater has nowhere to go—except straight down along your foundation. And trust me, that’s not where you want it. 

Foundation Damage – What You Should Look For

  • Cracks: They might be vertical or horizontal, and either way, they’re a warning sign.
  • Bowing Walls: Water pressure can actually push your walls inward. Not good.
  • Settling: Uneven settling can cause sloping floors or misaligned door frames as the foundation shifts.
  • Dampness and Mold: Accumulated moisture increases mold growth risk and affects indoor air quality.

Cost of Foundation Repairs

The cost of foundation repairs varies depending on the extent of the issues. Here are some price ranges:

  • Minor Cracks: Repairing small cracks can cost between $200 and $800.
  • Bowing Walls: Expect anywhere from $1,000 to $10,000.
  • Major Settling Issues: Depending on the severity, extensive repairs could be $5,000 to $20,000 or more.

Siding and Exterior Wall Damage

How Water Damages Siding

Leaky gutters can damage siding, causing warping, swelling, and rot in wood materials.

Impact on Different Siding Materials

Water damage affects different siding materials differently. Wood siding can rot, vinyl siding is resistant but not immune to fading and mold growth, and fiber cement is more durable but can crack if water seeps in.

Here’s a quick look at how different materials are affected:

Siding MaterialPossible Damage
WoodRot, warping, and mold
VinylFading, mold, and cracks
Fiber CementCracking and deterioration

Siding Damage – What to Look For

Siding damage may not be visible from a distance. We should look for specific signs that our siding is water-damaged:

  • Stains near the base of the siding.
  • Blistering or peeling paint.
  • Mold or mildew growth on the surface.

Roof Damage

How Leaky Gutters Affect the Roof

Leaks in gutters can cause water to overflow, weaken roofing materials, and cause shingles to curl, crack, or detach. In colder weather, accumulated water can increase the risk of ice dams, forcing water under shingles and causing more damage.

Leaks to Enter the Attic

Leaky gutters can let moisture seep into attics, foster mold growth, and damage insulation and wooden beams. If left unchecked, leaks can compromise the entire attic structure.

Fascia Rot

Fascia boards protect roof edges and can rot due to gutter leaks, weakening roof support, and causing more damage. Signs of rot are discoloration, soft spots, and visible cracks. Replacing rotting fascia early can prevent more extensive repairs.

Visuals of Roof Damage

Identifying roof damage early is key. We can look for several visual indicators:

  • Curling or Missing Shingles: These may mean water damage.
  • Stains on the Roof: Dark spots can indicate stagnant water.
  • Mold Growth: If we see mold, it often means moisture issues.

Landscape and Soil Erosion

When gutters don’t work, all that runoff water can trash your yard, damage your hardscape, and invite unwanted pests. Here’s what to watch for:

Landscaping Damage

  • Drowned flower beds and shrubs from constant runoff
  • Soil erosion that washes away nutrients plants need
  • Wilting or dying plants that can’t absorb water or nutrients properly
  • Loose or exposed roots due to missing topsoil

Water Pooling and Pest Problems

  • Standing water around your home creates breeding grounds for mosquitoes
  • Ants and rodents are drawn to moist spots for food and nesting

Hardscape Issues: Walkways & Driveways

  • Cracks and erosion in concrete or stone from poor drainage
  • Uneven surfaces that become tripping hazards
  • Stained or discolored concrete where water repeatedly flows or pools

What to Look For Outside

  • Thin patches of grass or bare soil
  • Pooling water near the home’s perimeter
  • Shifting or sinking sections of your paths or patios

Interior Water Damage

Once water gets into your home, the damage adds up fast—and it’s not always where you expect it. Here’s how leaky gutters lead to interior trouble:

Damage to Your Stuff

  • Furniture can warp or bend • Electronics can short circuit or malfunction • Clothing, bedding, and linens can take on water damage

Health Risks from Mold & Mildew

  • Wet environments = perfect conditions for mold and mildew to grow
  • Mold exposure can cause respiratory issues, allergies, and asthma attacks

Signs of Interior Water Damage

  • Dark stains on ceilings or walls
  • Peeling paint or bubbling wallpaper
  • Warped floors or soft spots underfoot• A musty smell in certain rooms or near the baseboards

How to Fix and Prevent Leaky Gutters

Keeping your gutters in shape doesn’t have to be a big deal, but ignoring them will cost you. Here’s how to stay ahead of leaks, clogs, and water damage:

Regular Gutter Inspections & Maintenance

  • Check your gutters twice a year—once in spring and once in fall
  • Look for rust, cracks, loose fittings, and blockages
  • Use a ladder and trowel to clear out leaves and debris safely
  • Don’t forget to reseal joints and adjust gutter angles to ensure proper flow
