8 Commercial Gutter Problems in Thunder Bay
If you own or manage a commercial property in Thunder Bay, your gutters are probably the last thing on your mind, until something goes wrong. And by the time something goes wrong, it usually means water damage, costly repairs, and a whole lot of headaches.
Commercial gutters are the drainage systems installed along the roofline of your building. Their job is simple: direct rainwater and snowmelt away from your structure so it does not pool, seep, or cause damage. But here in Thunder Bay, where we deal with heavy snowfall, freeze-thaw cycles, and serious spring rainstorms, gutters take on a tough job all year long.
The truth is, most commercial property owners only call for help when there is already a visible problem. This guide is here to change that. Whether you manage a retail plaza, an office building, a warehouse, or any other commercial space, understanding what can go wrong with your gutters, and why it matters, could save you thousands of dollars in repairs.
In this post, we are walking you through eight of the most common commercial gutter problems seen across Thunder Bay properties. You will learn how to spot them early, what causes them, and what you can do to prevent them from turning into bigger issues.

1. Clogged Gutters From Debris Buildup
Let's start with the most common one. Clogged gutters are the number one gutter problem for commercial properties in Thunder Bay, and honestly, it is easy to see why.
Between the trees dropping leaves in the fall, seeds and pollen in the spring, and general debris blowing around throughout the year, your gutters are constantly collecting material that does not belong there. For large commercial rooftops, that is a lot of surface area collecting a lot of junk.
When gutters clog up, water has nowhere to go. It backs up onto the roof, spills over the sides of the gutter, and can start working its way into your building's walls, windows, and foundation.
What to do: Schedule regular commercial gutter cleaning at least twice a year, ideally in the spring and fall. For properties with lots of trees nearby, three or four cleanings per year may be necessary. A professional gutter cleaning crew can clear out all that debris safely and efficiently, which keeps your drainage system working the way it should.
2. Ice Dams in the Winter Months
Thunder Bay winters are no joke. We get a lot of snow, and with our freeze-thaw cycles, ice dams are a real and serious problem for commercial gutters.
An ice dam forms when snow on the roof melts, runs down toward the eaves, and then refreezes before it can drain off the roof. This creates a ridge of ice that blocks proper drainage. Water then backs up under your roofing materials, which can lead to leaks inside the building.
For commercial properties, ice dams can be especially damaging because the rooftops are larger and the water has more places to seep in and cause trouble.
What to do: Make sure your roof insulation and ventilation are up to standard so heat is not escaping unevenly. Keep gutters clear heading into winter so water has a path to drain. If ice dams are a recurring issue, talk to a professional about heated gutter systems or other preventive options.
3. Sagging or Pulling Gutters
Have you noticed sections of your gutters starting to sag or pull away from the fascia board? This is a common sign that something is off, and it is not something you want to ignore.
Gutters sag for a few reasons. The most common cause is the weight of debris, standing water, or ice building up inside the gutter. Over time, that extra weight pulls the hangers loose or bends the gutter out of shape.
When gutters sag, they stop draining properly. Water sits in the low spots instead of flowing toward the downspouts, which speeds up corrosion and makes the problem worse over time.
What to do: Have the hangers inspected and replaced if needed. A professional can re-pitch the gutters so they drain correctly and secure any sections that have started to pull away from the building.
4. Leaking Joints and Seams
Commercial gutters are usually made up of multiple sections joined together. Over time, those joints and seams can crack, separate, or corrode, especially here in Thunder Bay where temperature swings put a lot of stress on building materials.
A leaking seam might seem like a minor issue, but water dripping from a joint can cause damage to your siding, your fascia boards, and even the foundation below if it is left unchecked.
What to do: Walk around your building during or after a heavy rain and look for water dripping from anywhere other than the downspouts. Leaking joints can often be resealed, but if the damage is severe, a section of gutter may need to be replaced entirely.
5. Improper Slope and Drainage
Here is something that surprises a lot of commercial property owners. Sometimes the gutter problem is not from wear and tear at all. It is from the gutters being installed at the wrong angle in the first place.
Gutters need to slope slightly toward the downspouts so water flows in the right direction. If they are too flat, water sits and stagnates. If they slope too steeply, they drain too fast and can overflow during heavy rain events. Getting the pitch just right is important.
What to do: If you notice standing water in your gutters long after a rain has passed, the slope may be the issue. This is a job for a professional who can assess the current pitch and make the necessary adjustments.
6. Downspout Blockages and Overflow
Your downspouts are just as important as the gutters themselves. They are responsible for carrying all that collected water away from your building and releasing it at a safe distance from your foundation.
When downspouts get clogged with debris, nests, or ice, water backs up into the gutter system and overflows, often right next to your building's foundation. Over time, this constant moisture can erode the soil around your foundation and eventually lead to cracking and structural issues.
What to do: Check your downspouts regularly, especially after heavy rain or at the end of winter. Make sure the discharge point is directing water at least a few feet away from your building. A gutter cleaning service will typically flush out downspouts as part of a standard cleaning.
7. Water Pooling Around the Foundation
If you are seeing water pool near the base of your building after a rain, your gutters or downspouts may not be doing their job. This is one of the most serious gutter-related issues a commercial property can face.
Water that consistently sits near your foundation will, over time, put pressure on foundation walls, create conditions for mold growth, and even seep into the basement or lower levels of your building. In a place like Thunder Bay, where the ground freezes and thaws regularly, that water can expand inside tiny cracks and make them bigger.
What to do: Check that downspouts are directed away from the building and that the grading around your property slopes away from the foundation. If pooling continues, it may be worth calling in a professional to assess your drainage system as a whole.
8. Corrosion and Rust on Older Gutter Systems
Commercial gutters are built to last, but they do not last forever. Older steel gutters are especially prone to rust and corrosion, particularly in a climate like Thunder Bay where they are constantly exposed to moisture, road salt in the air, and extreme temperature changes.
Once rust takes hold, it spreads. Small rust spots can become holes, and holes mean water is escaping somewhere it should not be.
What to do: Inspect your gutters every season and look for discolouration, flaking, or visible rust. If the corrosion is isolated to one section, it may be possible to replace just that part. If the entire system is aging and showing widespread rust, a full replacement is likely the more cost-effective option in the long run.
