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.
Localized repairs run $350 to $2,000 depending on the failure and the access, with a cracked pipe boot at the low end and a rebuilt valley or extensive flashing work at the high end. Full replacement on a typical Burlington home runs $9,000 to $22,000. The written price follows the diagnosis rather than preceding it.
It is common here and it is not a defect in your specific house. Builder grade shingles installed quickly during the subdivision booms frequently underdeliver on their rated life, particularly where nailing sat high or the sealant strip never fully bonded in the first summer. Sometimes targeted repair buys real time. Sometimes the first cycle is simply over, and 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 these are common on Burlington's 1960s and 70s stock. Flat sections need membrane work rather than shingle work, which is why a slope only roofer patches them and returns the following spring. The real question is whether there is enough fall to drain. Where there is, a properly detailed membrane lasts. Where there is not, the slope has to be built first, and we say so rather than selling a repair we expect to fail.
Yes, wherever conditions allow, and the written report documents the failure, the fix, and photographs of both. Waiting for the next storm to find out whether a repair worked is not a reasonable thing to ask a homeowner to do.
When the deck underneath has deteriorated, or when an earlier reroof was layered over the original shingles without anyone assessing what was below. In both cases repairs are temporary by definition because the problem is the assembly rather than the surface. We show you that in photographs rather than asserting it.
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. These are builder grade shingles installed at subdivision pace, and they let go at the sealant strip and the nail line somewhere between year fifteen and year twenty despite a longer rating on the wrapper. The roofs look alarming from the driveway and are frequently repairable, which is worth establishing before anyone quotes a 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. Middle and lower Burlington: aging flat sections over garages and rear additions, chimney flashing on 1960s masonry, and pipe boots that crack reliably around year fifteen.
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
Every repair produces a written report: the failure described by mechanism, dated photographs of the condition before and after, the materials used, and anything we noticed that will need attention later. No verbal only assessments, and no scope that grows once a crew is on the roof.
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 a different contractor tells you the whole roof needs replacing and you have photographic evidence of what was actually wrong.
