This family in North York had used DT Cleaning before. We had been out two years earlier to clean their eavestroughs - the system was clear, the downspouts were flowing, no problems noted. They called us back in March 2026 for a follow-up service.

Two years is a long time for a Toronto roofline. When our technician Vitaly arrived at their bungalow (Dmitriy dispatched him for this one based on the client history) and climbed to the rear, he found what two winters and two falls had left behind.
The gutters looked fine. The downspouts did not.
The eavestrough itself was not heavily packed. Two years of maintenance history meant the trough had not had time to fill completely. This is what regular service does - it resets the clock before the problem becomes structural.
What Vitaly found instead were two blocked downspouts. Both were packed with fine debris: asphalt granules shed from the shingles above, seed casings from the trees overhead, and a compression of small organic material that had washed down and settled at the downspout elbows. The trough drained slowly during light rain. During heavy rain, it did not drain at all - the water overflowed the front lip and ran straight down the exterior wall.
This is a common pattern on properties where the gutters are cleaned on schedule but the downspouts are not flushed and inspected individually. The trough looks clear. The problem is six inches below the surface, out of sight, building for a year or two until rain makes it visible.
The roof problem was separate - and more serious
While checking the full perimeter, Vitaly found damage at the rear roof peak. The shingles at the hip had separated. Below them: exposed board, damp to the touch, darkened from moisture absorption. This was not a gutter problem. This was a roofing problem that the eavestrough cleaning visit revealed.
The family had noticed water entering the house during rain but could not locate the source. The interior staining was consistent with the roof hip location. Water was entering at the lifted shingle, running inside the roof structure, and finding its way to an interior surface.
Without the roof inspection that accompanies every DT Cleaning visit, this would have continued through another season before the source was identified.
Two failure points on the same roof
On the opposite slope, Vitaly found a second area where shingles had lifted and separated from the underlayment. This was not connected to the hip damage. Two independent sections of roofing had failed, on different slopes, for different reasons - one from moisture cycling at the peak, one from wind or age-related seal failure on the flat run.
Finding both on the same visit is not unusual. Shingle degradation across a roof tends to progress uniformly. When one section goes, others on the same age of material are often close behind.
What we did and what the homeowners needed to know
Vitaly completed the full eavestrough cleaning: both downspouts flushed and cleared, all joints inspected, the full run checked for pitch and hanger condition. The gutter system was restored.
He then sat with the homeowners and walked through what he had found on the roof - both damaged sections, the likely entry point for the interior water, and what a roofing contractor would need to address. He documented everything in photos and left a written inspection note.
The clients knew their roof had an issue. They did not know where it was entering, or that there were two separate sections involved. Now they did.
This is what routine maintenance provides: clean gutters and a set of eyes on the full exterior at regular intervals. We also discussed leaf guard installation for the rear run to reduce the debris load reaching the downspouts and extend the service interval.

Frequently asked questions: eavestrough cleaning in North York
How do blocked downspouts cause water to overflow the gutters?
When a downspout is blocked, water fills the eavestrough during rain and has nowhere to drain. The trough fills from the bottom up and spills over the front edge, sending water down the exterior wall instead of away from the foundation. Even a partially blocked downspout significantly reduces drainage capacity. Two blocked downspouts on the same run means the entire rear eavestrough overflows in moderate rain.
How often should eavestroughs be professionally cleaned in North York?
Twice a year is the recommended standard: once in late spring after seeds, pollen, and tree debris, and once in late fall after leaf drop. Two years is the outer limit for most North York properties before blockage accumulates to the point of causing overflow. Properties with heavy tree coverage may need service annually at minimum.
What causes downspouts to block if the gutters look relatively clean?
Small debris like shingle granules and seed pods passes through the eavestrough and packs at the elbow where the downspout bends away from the house. Leaves and branches that enter the downspout top compound this. The trough itself can appear clear while the downspout is fully blocked below.
Can roof damage be identified during a gutter cleaning visit?
Yes, and it frequently is. Our technicians inspect the roofline as part of every eavestrough cleaning. Lifted shingles, exposed underlayment, separated flashing, and soft spots on the fascia are all visible from the roof edge. We document anything we find and provide a written report. For structural repairs we refer clients to licensed roofing contractors.
If my eavestroughs were cleaned two years ago, do I need service again?
Almost certainly yes. Two years is enough time for downspouts to partially or fully block with fine debris, for joints to develop small seal failures, and for any roof damage to progress. A two-year interval is the maximum, not the target. Most North York homes benefit from annual service.
What does DT Cleaning do when it finds roof damage during a visit?
We photograph the damage, note the location and approximate scale, and include it in a written inspection summary provided to the homeowner on the same day. We explain what we found, what the likely cause is, and what type of contractor should address it. We do not perform roofing repairs ourselves, but we can recommend licensed roofers in the North York and Toronto area.
