The difference

Why you should call us first.

We answer at 2am. When water is coming through a ceiling, the time between the call and the first tarp is the entire job.

Blue Knight was, by far, the best. Responsive, ethical, totally professional — and their crew went above and beyond at no extra charge.

They installed a full new roof in one day. The crew worked around the house without us hardly knowing they were there.

I 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.

Scarborough, ON·Google

Flat roof replacement on a commercial unit. Clean, fast, no surprises on the invoice. The crew left the site cleaner than they found it.

Mississauga, ON·GuildQuality

Called after a storm damaged our roof. Someone was on site within hours, tarped everything, and had us fully repaired before the next rain.

Vaughan, ON·HomeStars

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.

FAQ

Emergency Roof Repair questions for Markham.

Typically within 60 minutes to the western and central parts of the city. Cornell, Greensborough, and the eastern edge run longer, particularly in the afternoon, and we tell you a realistic window on the call rather than repeating one number regardless of where you are.

We stop the water with secured tarping or a temporary membrane patch, photograph the failure before covering it, and trace the entry point. You are left with the intrusion contained and a written account of what failed, which becomes the basis for both the permanent repair quote and any insurance claim.

In winter that is nearly always an ice dam releasing. Ice built at the eave over several cold days, backed meltwater up under the shingles, and let go when the temperature moved. Tarping achieves nothing because the water is already inside the assembly, so the work is clearing a channel through the dam, protecting the interior, and then documenting the attic conditions that allowed it.

If water is reaching insulation, drywall, or electrical fixtures, treat it as an emergency even when the drip looks minor, because moisture spreads through the deck long before it shows on a ceiling. A damp stain that has not grown in a week can usually wait for a scheduled inspection, and we will tell you which situation you are in rather than dispatching at premium rates for something that can wait.

Yes, and the containment method changes for it. The standard way to secure an emergency tarp is to fasten through the roof covering, which is fine on asphalt that is coming off anyway. Do that to slate or original metalwork and you have broken material that costs more than the leak did. Our crews carry weighted and battened systems that hold without fastening through heritage material.

Yes. We photograph before covering anything and provide a written report formatted for submission: failure description, probable cause, and recommended repair. Insurers separate sudden damage from gradual wear, and dated evidence taken before the containment went on is what settles that question.

In Depth

When water is actively entering a building the order does not vary. Contain first, because every minute it runs costs more insulation and drywall. Photograph second, before any covering goes on, because that record is what an insurer decides the claim on and it cannot be recreated afterwards. Diagnose third, and quote the permanent repair in daylight.

Markham's emergencies follow its housing. Wind events lift shingles across the open subdivision streets in Cornell, Berczy, and Cathedraltown, where there is little mature tree cover to break a gust front. Winter calls tend to be ice damming on houses with buried soffit intake. Heritage property in Unionville produces a different call again, usually a chimney flashing that has finally let go after a long decline.

Wind Events on Open Subdivision Streets

Markham's newer neighbourhoods catch wind that older treed areas break up. Cornell, Cathedraltown, Berczy, and Greensborough were laid out with wide streets and young landscaping, which gives a gust front a clean run at exposed roof planes. The failures skew toward things being lifted and torn rather than gradually worn through: ridge caps peeled back, drip edge unfastened along a rake, whole courses removed from a windward slope.

That also changes the containment. A tarp on an exposed subdivision roof has to be battened properly rather than weighted, or it is in a neighbour's yard by morning. We take the extra time on site rather than returning the next day to do it again.

Containment First, Quote Later

The emergency visit and the permanent repair are deliberately separate steps. On the night the job is to stop the water, record what failed, and leave the building secure. We do not quote a permanent scope while water is coming through a ceiling, partly because nobody decides well in that state and partly because the full extent is often not visible until things dry out.

What you have before we leave is the containment in place, photographs taken before it went on, and a plain account of what we found. The repair proposal follows with a price and the reasoning attached. If the containment will hold safely for several weeks while you get other quotes, we say that as well.
