5 Signs Your Gutters Are Clogged After Winter: A Commercial Guidest
Winter can leave your gutters clogged and damaged. Learn the 5 key signs to watch for after snow melts—and how to prevent costly water damage with professional eavestrough cleaning.
After a long winter in Ottawa, your gutters have likely taken a hit.
Snow, ice, and debris don’t just disappear when temperatures rise—they stay behind, creating blockages that can quietly damage your property if left unchecked.
The good news? Your gutters usually give clear warning signs before bigger problems start.
Why Gutters Get Clogged After Winter
Winter creates the perfect storm for gutter issues.
As snow builds up and melts repeatedly, it pushes debris into your system, including:
Leaves and organic matter from fall
Twigs and pine needles
Roof shingle grit
Ice buildup inside downspouts
Freeze-thaw cycles also put stress on your system, leading to cracks, sagging, and misalignment.

Spring Eavestrough Cleaning: Why It Matters After the Snow Melts

1. Water Overflowing From Your Gutters
If water spills over the sides during rain or snowmelt, your gutters are likely clogged.
Instead of draining properly, water backs up and overflows—leading to:
Damage to siding and windows
Moisture entering walls
Increased risk of mould
👉 The Environmental Protection Agency highlights proper drainage as a key factor in preventing structural water damage.
2. Sagging Gutters or Loose Sections
Gutters are built to handle water, not heavy debris and ice.
If they appear to be pulling away from your building, it’s often due to:
Built-up debris
Trapped water
Ice weight from winter
This is an early warning sign that your system needs attention before it fails.
3. Water Stains on Siding or Exterior Walls
Dark streaks or stains on your building are a sign that water isn’t flowing where it should.
Clogged gutters force water down the exterior walls, which can lead to:
Peeling paint
Mould or mildew growth
Damage to exterior finishes
4. Water Pooling Around the Foundation
One of the most serious signs is water collecting near the base of your building.
When gutters can’t direct water away, it pools around the foundation—leading to:
Cracks and structural weakening
Basement leaks or flooding
Soil erosion
👉 The Canada Mortgage and Housing Corporation emphasizes that proper drainage is critical to preventing foundation damage.
5. Visible Debris or Plants in Your Gutters
If you can see debris—or even plants—growing in your gutters, there’s already a major blockage.
This usually means:
Debris has been sitting for a long time.
Moisture is trapped in the system.
Drainage is severely restricted.
Left untreated, this can speed up gutter deterioration.

Why Post-Winter Clogs Are More Dangerous
Winter doesn’t just clog your gutters—it weakens them.
Ice expansion can create small cracks, while melting snow compacts debris into dense blockages. When spring rain hits, your system is already under stress.
👉 That’s why many gutter problems show up right after winter—not during it.
