Roof Repair in Burlington
Ice dams below the escarpment, tired original shingles in Alton Village, and ponding flat roofs over Freeman and Aldershot garages. Every Burlington roof repair starts by finding where the water actually gets in, then fixing that detail and nothing it does not need.

Luciano did not try to sell me a new roof. Appreciated the honesty — he showed up when he said he would.
We had a leak diagnosed by two other contractors who could not find the source. Blue Knight found it on the first visit and fixed it the same week.
Flat roof replacement on a commercial unit. Clean, fast, no surprises on the invoice. The crew left the site cleaner than they found it.
Called after a storm damaged our roof. Someone was on site within hours, tarped everything, and had us fully repaired before the next rain.
Had a slow basement leak for years. Every other company just caulked it. Blue Knight found the actual source and did a proper waterproofing job. No issues since.
Our neighbours recommended them for a valley repair. Small job, but they treated it like it mattered — showed up on time, matched the shingles perfectly, and charged exactly what they quoted.

Roof Repair questions for Burlington.
Most of the repairs we carry out in Burlington land between $350 and $2,000. A split collar on a vent stack sits near the bottom of that range, and rebuilding a valley that has taken years of escarpment ice sits near the top. If the roof is past repairing, replacing it on an average Burlington house falls between $9,000 and $22,000, and you see the written diagnosis before any figure.
It is common here and it is not a defect in your specific house. Much of Alton Village was roofed in a short window with one grade of shingle, and where the nails sat above the adhesive line, or the adhesive never took hold during the house's first warm season, the tabs have been held down by little more than their own weight. Sometimes targeted repair buys real time and sometimes the first cycle is simply over, so we open a section to tell you which.
Two reasons stacking. The upper city gets more snow and more freeze and thaw cycling, so there is more water available and more opportunity for it to refreeze at a cold eave. And the older housing up there frequently has modest soffit intake that was made worse by a later insulation upgrade burying the vents. The roof is where you see it, but the fix is usually in the attic.
Yes, and they turn up on street after street of 1960s and 70s housing in Aldershot, Freeman and Brant Hills. A low roof over a garage or a rear family room needs a membrane, and a crew that only works on sloped roofs tends to patch it with shingle materials that were never meant to sit flat. Whether a repair lasts comes down to drainage: where water clears the surface within a day, a properly detailed membrane holds, and where it ponds for days the deck has to be re-pitched first, which the written quote will say plainly.
Wherever the weather and the detail allow, usually by running water over the repaired area while someone watches from the attic below. The written report then sets out the failure, the change we made and before and after photographs, so nobody has to wait for the next storm off the lake to learn whether it worked.
Once the deck underneath has gone soft, or when a previous owner had new shingles laid over the old ones without anyone checking what was below. Overlaid roofs turn up often on the older lakeshore and Aldershot houses, where the extra layer conceals rot, holds heat against the shingles and leaves new nails little solid wood to bite into. Past that point no patch will outlive the roof around it, and photographs of the deck show you why.
Shade and leaf fall keep a roof damp for longer, which feeds moss on the north-facing slopes and packs valleys and eavestroughs with debris every autumn, a pattern we see across Tyandaga and Roseland. Water that cannot get out of a clogged valley backs up under the shingle edges, and in winter the same blockage anchors an ice dam. We reline worn valleys, repair the lifted edges and tell you which overhanging limbs are feeding the problem.
Roof repair in Burlington splits along the city's climb. Up near Mountainside and Kilbride the dominant failure is ice damming at the eaves, driven by attic conditions rather than by anything on the roof surface. Meltwater backs up under the shingles during a thaw and releases into the ceiling below, usually on a day with no rain in the forecast, which is why owners so often report it as mysterious.
Down through Alton Village, Orchard, and Millcroft the failures look different. Those neighbourhoods were roofed in a handful of busy years with whatever shingle the builder bought in bulk, and on the more exposed streets the tabs are now losing their grip where the adhesive strip has dried out or the nails were driven too high to catch the course below. Wind off the lake and down from the escarpment finds those loose tabs first. A roof with a few dozen lifted tabs can look finished from the sidewalk and still have years in it once the loose courses are resealed or replaced, so we check that before anyone mentions replacement.
What Fails on Burlington Roofs
The patterns are consistent enough to predict once you know which part of the city you are in. Upper Burlington: ice damming at eaves, stressed valley metal from repeated freeze and thaw, and wind lifted ridge caps on exposed lots. Closer to the lake, between the QEW and Lakeshore Road: flat roofs over carports and back additions that have been patched more than once, chimney flashing on 1950s and 60s brick that has worked loose, and rubber collars on vent stacks that have split and let water run down the pipe into a bathroom ceiling.
Across the newer subdivisions it is almost always the shingles themselves rather than the details, because the details were installed to a current standard and the material was the corner that got cut. That distinction matters, because a shingle problem on a sound roof is a far smaller job than the reverse.
Written Diagnosis on Every Burlington Repair
Each Burlington repair ends with a written record in plain terms: what let the water in and why it happened at that spot, dated photographs from before and after, the materials that went on, and any nearby detail we expect to need work in the next few seasons. The scope agreed in writing is the scope carried out. If opening the roof reveals something nobody could see from outside, you get photographs and a written price before anything changes.
That documentation earns its keep at three moments. When you sell the house and a buyer's inspector asks what was done. When you file a claim and an adjuster needs to see whether damage was sudden or gradual. And when another company walks your roof after a windstorm off the lake and recommends tearing it all off, the photographs show exactly which detail failed and how it was put right.
