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.

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.

Emergency Roof Repair questions for Downtown Toronto.
Within 60 minutes, at any hour, since the core is one of our main service areas. The first thing we ask on the call is what sits below the leak, so the crew arrives knowing whether an electrical room, a shaft, or an occupied tenancy is at risk.
Yes. We coordinate with building management from the first call and include them in on-site communication.
Yes. Commercial membrane emergencies, including large-span flat roofs and parapet failures, are part of our emergency response capability.
Yes. Every emergency call ends with a written damage report carrying photographs taken before any containment went on, the failed element and the path the water took, and the weather event referenced where the evidence supports it, which is the record a carrier and its adjuster work from.
Yes. Water coming into a garage level, a below-grade commercial unit, or a mechanical room is part of our emergency scope, and the first job is the same as on a roof: stop the flow where we can, protect what it is heading for, and record the entry point for the permanent repair.
That changes the order of operations. Anything threatening a main electrical room, an elevator shaft, or a critical equipment space is treated as the priority regardless of where the roof breach is, because the consequential damage vastly exceeds the roofing damage. We coordinate with building operations to isolate or protect the affected equipment, contain the water above and divert it to a controlled discharge point, and only then work on the source. We will also say clearly if the situation needs your electrical contractor or elevator service provider on site alongside us.
Not a tarp. Sheeting a large-span roof tends to pond water somewhere new and can overload a deck, so containment normally means locating the entry and patching the failed seam or penetration with self-adhered or compatible membrane. Where the breach is extensive we may build a temporary controlled diversion to a functioning drain instead of trying to seal it, which keeps the water moving predictably until a permanent repair is possible. The method depends on the assembly, and we will tell you what we did and why in the report.
Yes, provided the access arrangements are established. We will need the on-call contact for building operations, the route and any keys, fobs, or escort requirements, and confirmation of whether roof hatch or stair access is available at that hour. Buildings that have given us this information in advance get materially faster response, which is a good argument for sorting it out before an emergency rather than during one.
It does not delay containment, and it should not. Stopping active water intrusion is protective of the building and takes precedence. What it affects is the permanent repair, where alterations touching heritage attributes may require approval and material matching. We keep the emergency intervention reversible where we reasonably can, avoid fixings into historic masonry when an alternative exists, and document the pre-existing condition thoroughly so the permanent scope can be approved without dispute about what was there beforehand.
It depends on the lease and on where the failure actually is, which is precisely why the documentation from the first visit matters so much. Our report states the entry point, the failed element, and the path the water took, in plain terms. That is what allows the building owner, the tenant, and their respective insurers to establish responsibility from evidence rather than argument. We do not adjudicate it, and we make sure the record is clear enough that it can be adjudicated properly.
Emergency roof failures in occupied downtown Toronto buildings can affect commercial tenants, condo residents, and building operations simultaneously. Our emergency response includes immediate containment and building management notification as part of the first call.
Downtown emergencies carry consequences a house does not. Water reaching an elevator shaft, a main electrical room, or a server or telecom space escalates from a building repair into a business interruption within minutes, and the containment priority is set by what is below the breach rather than by the size of the breach. On a multi-tenant floor there is also the question of whose space the water is entering and whose responsibility the failed element is, which is why we document the entry point precisely on the first visit.
We carry materials for both membrane and flashing emergency repairs in our downtown-capable vehicles, allowing us to contain and often permanently repair in a single dispatch.
24/7 Emergency Roofing in Downtown Toronto
Downtown Toronto buildings often have more complex emergency response requirements than residential properties. Access protocols, building management notification, and occupant safety considerations all factor into how we approach downtown emergency calls.
We've developed efficient protocols for downtown emergency response that minimize disruption while addressing the envelope failure quickly. The first question on arrival is what sits below the breach, because water heading for an elevator shaft, a main electrical room, or critical equipment sets the containment priority regardless of the size of the roof failure.
Containment That Does Not Create a Second Problem
Containment on a large commercial roof is a different discipline from containment on a house, and the wrong approach makes things worse. Sheeting a large-span membrane pushes water to a new low point and can load a deck that was not designed for standing water. Sealing a breach without considering where the water then goes simply relocates the leak into a different tenancy.
So the method follows the assembly. Locating the entry and patching the failed seam or penetration with compatible membrane is usually the right answer. Where the failure is too extensive to close safely, building a controlled diversion to a functioning drain keeps the water moving predictably until a permanent repair can be scheduled.
In both cases we record what was done and why, so the permanent scope starts from an accurate picture rather than from guesswork about what the emergency crew left behind.
Storm Damage in the Downtown Core
Downtown Toronto's density means storm events can affect multiple buildings simultaneously. Major weather systems that produce high winds, particularly those that track across Lake Ontario, can create dozens of concurrent roofing failures in the downtown core.
We maintain capacity to respond to multiple concurrent downtown calls during major storm events, and we triage by consequence rather than by order of calling. Active intrusion into occupied space, anything with an electrical risk, and anything threatening building services come first, and we give realistic windows rather than optimistic ones so building operations can take interim measures.
Documentation is part of every call: photographs before any covering is applied, the failure mode described in the terms an adjuster and a property manager both work in, and the weather event referenced where the evidence supports it.
We also cover nearby cities.
