Shingle Roof
Gutters that are sized for Ontario snowmelt, not just installed to look finished
A gutter that's slightly under-sloped or undersized works fine in a light summer rain and fails the first time spring snowmelt hits it fast. We scope gutters around how water actually moves off a GTA roof through the seasons.

Gutters do more work here than people expect
In a region with heavy snow load off Lake Ontario and a hard freeze-thaw cycle, gutters aren't just cosmetic edge trim — they're the difference between water leaving your foundation area and water finding its way into your fascia, soffit, or basement. Cheap gutter installs skip slope calculation and hanger spacing to save an hour of labour, and it shows up as sagging within a year or two.
Ice dams start at the gutter line
When heat escapes through poorly ventilated attics, it melts snow on the upper roof, which refreezes at the cooler eave and gutter line. Properly sloped, properly sized gutters combined with correct ventilation reduce how much ice builds up there in the first place.
Hanger spacing matters under snow load
Gutters loaded with wet lake-effect snow and ice need tighter hanger spacing than a spec sheet minimum. We space hangers for the load this region actually sees, not the manufacturer's bare minimum.
Downspout placement affects your foundation
Older GTA homes often have downspouts dumping water right against the foundation. We'll flag that during a gutter job even if it means a slightly larger scope than 'just replace the gutters.'
Seamless vs sectional isn't just a style choice
Seamless aluminum gutters have fewer joints to leak or catch debris, which matters more in a climate with this much freeze-thaw cycling than in a milder one.
Sagging gutters after one winter usually means bad slope, not bad material
We get calls about gutters that are pulling away from the fascia or visibly sagging after a single winter. In most cases the aluminum itself is fine — the problem is a slope that wasn't calculated correctly for the roof's drainage area, or hangers spaced too far apart for the snow and ice load this region puts on them.
We calculate slope and hanger spacing for your roof, in writing
Our gutter quotes specify slope-per-foot, hanger spacing, and downspout count and placement based on your roof's actual drainage area — not a flat per-foot price with no detail behind it. If your existing downspouts are dumping at the foundation, we'll note that as part of the scope.

Gutter installation & repair questions
How often should gutters be cleaned in the GTA?
Most homes here benefit from a clean in late fall after leaves drop and again in spring before heavy snowmelt, though tree cover and roof pitch change that.
Do you install gutter guards?
Yes, where they make sense for the tree cover and roof design. We'll tell you honestly if guards aren't worth it for your specific setup.
Can bad gutters cause ice dams?
They're a contributing factor alongside attic ventilation and insulation. We look at all three together rather than treating gutters in isolation.
What material do you install?
Seamless aluminum in most cases, sized and gauged appropriately for the snow and ice load this region sees.
Do you repair sagging gutters or only replace them?
If the sag is due to a few bad hangers or a short section, we'll repair it. Full replacement is only what we recommend when the whole run has slope or sizing problems.
