Eavestrough & Gutters in Thunder Bay
Eavestrough and gutter installation, repair, and guards for Thunder Bay homes, sized for heavy snowmelt and set up to help manage ice damming.
Eavestroughs Built for Northern Snowmelt
Eavestroughs do quiet, important work: they carry water off your roof and away from your fascia, soffit, and foundation. In Thunder Bay they have a harder job than in milder places, because they deal not just with rain but with the meltwater from a heavy snowpack and the freeze-thaw that comes with our winters. An undersized or neglected eavestrough overflows, sags, and freezes at exactly the time of year it matters most.

Sized for the Volume We Get
Standard 5-inch eavestrough is fine for many homes, but on roofs with large catchment areas, steep pitches, or a history of ice problems, we often recommend upsizing to 6-inch trough with larger downspouts. The bigger system moves the volume of water and snowmelt that Thunder Bay roofs shed, and it is less likely to overflow and freeze at the edge. We size the eavestrough to your actual roof rather than defaulting to one size for everything.
Eavestroughs and Ice Dams
Let us be straight about this, because there is a lot of confusion. Eavestroughs do not cause ice dams, and no eavestrough setup will fix an ice-dam problem on its own. The dam forms because heat escapes into the attic, melts the snowpack, and the meltwater refreezes at the cold eave. That is a roof and attic problem, solved with ventilation and ice-and-water membrane, covered under our roof repair and roof replacement work.
What eavestroughs do is play a supporting role. Clogged or undersized troughs hold water at the edge where it freezes and adds to the ice. Clear, properly sized troughs help meltwater get away. So good eavestroughs are part of managing winter water, just not the whole answer.
Gutter Guards for Treed Lots
In the greener parts of the city and out in the rural areas around Oliver Paipoonge and Kakabeka Falls, treed lots drop needles and leaves into eavestroughs all season. That debris clogs the trough, traps moisture against the roof edge, and makes winter freezing worse. Gutter guards keep the trough flowing and cut way down on cleaning. We can recommend and install a guard system suited to the debris your home deals with.
Repair, Replace, or Bundle
If your eavestrough is sagging, leaking, or pitched wrong, water is spilling where it causes rot to the soffit and fascia and moisture problems at the foundation. We repair what can be saved and replace what cannot. When we are already on site for a roof replacement, replacing aging eavestrough at the same time is efficient and gets the whole edge-of-roof system working together.

Frequently Asked Questions
How do eavestroughs relate to ice dams in Thunder Bay?
Eavestroughs do not cause ice dams, but they are part of the picture. When meltwater backs up at a cold eave, it pools and freezes in and around the eavestrough, adding to the ice and the weight at the roof edge. Clogged or undersized eavestroughs make it worse by holding water where it can freeze. Properly sized, clear eavestroughs help meltwater get away from the roof, but the real ice-dam fix is attic ventilation and ice-and-water membrane on the roof itself.
What size eavestrough do I need for a Thunder Bay home?
On roofs with large catchment areas, steep pitches, or recurring ice problems, we often recommend upsizing to 6-inch eavestrough with larger downspouts, rather than the standard 5-inch. The bigger trough moves the volume of water and snowmelt our climate produces and is less prone to overflowing and freezing at the edge. We size it to your specific roof.
Should I get gutter guards?
Gutter guards are worth it on treed lots, common in the greener parts of Thunder Bay and the rural areas, where falling needles and leaves clog eavestroughs and trap moisture against the roof. Guards keep the trough flowing and cut down on cleaning. We can recommend a guard system suited to your home and the debris it deals with.
Can damaged eavestroughs hurt my roof or foundation?
Yes. Eavestroughs that are sagging, leaking, or improperly pitched let water spill where it should not, against the fascia and soffit where it causes rot, and down next to the foundation where it can cause moisture problems. In winter that spilled water also freezes into hazards. Keeping the eavestrough sound and properly pitched protects the roofline and the rest of the house.
Do you replace eavestroughs at the same time as the roof?
Often, yes, and it usually makes sense. When we are already on site for a roof replacement, replacing aging eavestrough at the same time is efficient and ensures the whole edge-of-roof system, shingles, flashing, eavestrough, and soffit and fascia, works together. We are glad to bundle it.
