Active leaks anywhere in the GTA get same-day priority dispatch. We answer at 2am, including weekends and holidays.
Complete liability coverage on every job. All work is documented and you are protected from start to finish.
Inspection reports, repair documentation, and scope estimates in writing before we touch anything.
We've worked on tens of thousands of GTA buildings. We recognise failure patterns before they become emergencies.
We trace the actual failure mode before proposing a scope, and we quote what that scope requires rather than inventing urgency.

Rated 5 out of 5Blue Knight was, by far, the best. Responsive, ethical, totally professional — and their crew went above and beyond at no extra charge.
Rated 5 out of 5They installed a full new roof in one day. The crew worked around the house without us hardly knowing they were there.
Rated 5 out of 5I emailed at 4 a.m. and spoke with someone that same day. Estimate and completed work all within one day. Pricing was fair, work was excellent.

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.

We work across all areas of The Beaches. If you don't see your neighbourhood listed, we almost certainly cover it.
The whole neighbourhood, from Woodbine Beach east to Fallingbrook and Birchcliff, and from the boardwalk up through Kingston Road Village to the Main and Danforth edge. Kew Gardens and the Queen Street East shops sit roughly in the middle, and because the neighbourhood is a narrow strip along the lake, a call from Fallingbrook gets the same response as one near Woodbine.
We do. Permits go through Toronto Building and are needed when roof structure changes or a foundation is altered, while a straight reroof in the same material usually needs none. What catches people out here is the lot width and the street parking, since staging material on a narrow Beach street often needs its own arrangement, and we sort that out before the first day rather than on it.
It is measurable and it is the reason we specify differently in the Lower Beach than we would three kilometres inland. Humidity runs higher year round, freeze-thaw cycles at the eaves are more frequent, and flashing metal and fasteners stay damp for longer, so they corrode faster. The practical result is that a material choice that lasts perfectly well in Leaside underperforms within sight of the water.
Rarely, even when they look alike from the street. A Victorian on the flat near Balmy Beach and an Edwardian up near Kingston Road are the same era and often the same builder, and they will not have the same problems. Recognising which one we are looking at is most of the diagnosis.
Yes. Bay and gable fronts, steep dormers, decorative wood shingles in the gable ends, and old copper or galvanized valleys are regular work for us, and we match slate, cedar, or copper where the original is worth keeping instead of covering it over in asphalt. When matching a feature would cost more than it gives back, we tell you that honestly and show you the alternatives.
Mostly because of how the top floor was built. Many of these houses have a half storey tucked under the roof, with sloped ceilings and knee walls that leave very little room for insulation or airflow right where heat escapes into the deck. Combine that with the repeated thaw and refreeze near the lake and snow melts on the upper slope, freezes again at the cold eave, and backs water up under the shingles.
It can, at both ends of the building. Partway down one of the streets running south to the water, a house receives runoff from the lots above it, so the grading, downspout discharge, and window wells on the uphill side deserve a close look. The same fall in the ground often leaves a tall rear wall and an awkward climb to the back of the roof, which we plan for before quoting.
The Beaches sits at the eastern end of Lake Ontario's north shore, where lake-effect weather patterns produce specific roofing conditions that inland Toronto neighbourhoods don't face. Higher humidity year-round, lake-effect ice storms, and wind-driven moisture from open lake exposure all contribute to accelerated roofing degradation.
Driving rain off the water is what explains a Beach house leaking on a night when the rainfall total looks ordinary. Rain that drops straight down runs off a roof exactly the way every detail was designed to handle. Rain blown sideways off the lake gets forced up under the lower edge of each shingle course and in behind siding and trim, so a house can take a heavy vertical downpour without trouble and then leak in a modest storm that arrives on an easterly.
The Beaches' Victorian and Edwardian housing stock has roofline characteristics that distinguish it from post-war residential, original masonry chimneys, complex multi-valley designs, and a heritage character that careful restoration respects.
These roofs also carry a hundred years of accumulated repair decisions, and the record of those decisions is usually only readable once something comes off. Original detailing sits under two or three later interventions of varying quality, and the failure being reported is often the newest of them rather than the oldest.
The slope running up toward Kingston Road divides the neighbourhood into two working conditions. Below it, on the flat ground toward the boardwalk, properties sit close to the water table and take the full force of weather arriving off open lake. Above it, the ground is higher and drier and the exposure is broken by the rise itself and by mature tree canopy.
So the same question gets different answers depending on the address. A wet basement in the Lower Beach is usually about groundwater and hydrostatic pressure. The same complaint in the Upper Beach more often traces to surface water, grading, and downspouts discharging where they should not. Diagnosing one as the other wastes money on a system that was never going to work.
The Beaches is one of Toronto's most distinctive neighbourhoods. Victorian and Edwardian homes along tree-lined streets near Lake Ontario, with a community character that residents protect carefully. The housing stock ranges from 1890s workers' cottages to substantial 1920s and 30s detached homes.
Proximity to Lake Ontario has measurable effects on building envelopes here. Humidity is higher year-round. Freeze-thaw cycling at the eaves is harder on these roofs than on houses a few kilometres further from the shore. Constant moisture and wind-driven spray off the lake keep metal flashings wet for longer, which accelerates corrosion. Homes in the lower Beach areas are exposed to wind-driven moisture from the lake in ways that affect roofing material durability.
The neighbourhood also rises as you move north. The flat ground near the boardwalk gives way to a distinct slope up toward Kingston Road, and properties on the two halves sit at meaningfully different heights above the water table. For a Beach basement, which half of that slope the house sits on usually matters more than the year its foundation went in.
