We photograph and document all storm damage before applying temporary protection. That documentation matters for insurance claims.

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 Don Mills.
Typically well inside 60 minutes, because our shop is a short run from the neighbourhood. Response here is among the fastest anywhere in our service area, and we will tell you a realistic time on the call rather than a standard figure.
They seal the opening with temporary membrane, photograph the damage before it is covered, and then follow the water back to where it got in, which on a Don Mills flat roof can be several metres from the stain on your ceiling. By the time they pack up, the water has stopped and you hold a written note of what failed.
Yes. We bond a temporary membrane over the failure instead of laying plastic on top, and we work it so water still runs to the drain rather than pooling in a fresh hollow. Doing that properly in the dark and the wet is a skill, and it is the reason a shingle crew struggles with these calls.
Yes, any night of the week, weekends and holidays included. On a flat roof the case for answering at that hour is stronger than usual, because a membrane failure moves volume rather than dripping, and the damage below accumulates quickly.
Yes. Large span membrane containment is regular work for us, and on an occupied building it has to be done without creating a hazard below or ponding water somewhere new. Afterwards the property manager receives a written report laid out so it can be acted on the same day.
It is written with that in mind. Photographs are taken before anything goes over the damage, and the report sets out the failure in a form you can submit to your insurer. On a flat roof that record matters more than usual, because the visible interior damage is so often remote from the actual failure and an adjuster will otherwise draw the wrong conclusion about cause.
It can be, when the carport roof ties into the house, as it often does on these mid-century designs. Water getting in where the two roofs meet can run along the framing into a wall or ceiling of the living space, so we contain it the same way as the main roof and check that junction before we leave.
A leak on a flat roof moves faster than one on a slope, because water that gets through a membrane spreads across the deck and comes down wherever it finds a gap. So on a Don Mills call the first job is stopping the flow, the second is photographing the opening before anything is laid over it, since that image is what an insurer will look at, and the third is tracing where the water actually entered.
Containment here needs different materials from a conventional emergency call. A tarp works on a slope because gravity holds it and sheds water off it. On a low slope or flat roof, plastic sheeting lifts, gathers water in its folds, and often makes things worse, so the trucks we send to Don Mills carry self adhered temporary membrane that bonds in whatever conditions the night brings.
Why a Tarp Is the Wrong Tool Here
On a sloped roof a tarp works because gravity does most of the job: it holds the sheet down and moves water off it. On a flat roof neither of those is true. The sheet has nothing to shed water into, it collects water in every fold, and the added weight sits over an assembly that may already be compromised.
So the correct containment is a temporary membrane bonded to the existing surface, detailed so water still reaches the drain rather than pooling at a new low point. Our trucks are stocked for exactly that, which is the practical case for calling a crew that works on flat roofs routinely rather than the first number that picks up.
Why the Repair Quote Comes Later
We never price the permanent fix on the night of the leak. The emergency visit has a short list: stop the water, document the failure, and leave the building sealed. A proper scope has to wait, partly because a choice made with water coming through the ceiling is seldom a sound one, and partly because on a membrane roof nobody can see how far the moisture has spread until the assembly has been opened and checked.
You keep the containment, the pictures taken ahead of it, and our written account of the failure. Once the assembly has been checked, a repair proposal follows, with the price and the reasons for it.
