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.

1. Clogged Gutters From Debris Buildup
Clogged gutters are the number one gutter problem for commercial properties in Thunder Bay. 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.
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: Build the gutter-cleaning schedule around tree cover, roofline access, previous blockages, and seasonal conditions. The right number of visits depends on the property.
2. Ice Dams in the Winter Months
Thunder Bay winters are no joke. 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.
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.
3. Sagging or Pulling Gutters
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.
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.
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
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.
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. 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.
What to do: Check visible downspout discharge after heavy rain or winter. If water is pooling near the building, ask the appropriate drainage professional to assess the outlet and surrounding grade.
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.
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
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.
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, a full replacement is likely the more cost-effective option in the long run.
