Why our inspections actually tell you something.
Physical access
Written reports
Material-specific assessment
Remaining life estimates
Core sampling available
Annual programs
Physical access
We get on the roof. Every inspection involves hands-on access to the roofing surface, not an assessment from the ground or edge.
Written reports
Our reports are formatted with the detail that lenders, insurance carriers, and property managers require.
Material-specific assessment
Heritage roofing materials require material-specific assessment. We bring that expertise, not a generic residential checklist.
Remaining life estimates
Every report includes an estimated remaining useful life and severity-ranked deficiency list, suitable for purchase negotiations.
Core sampling available
For flat-roof systems, we offer core sampling to assess membrane saturation and deck condition below the surface.
Annual programs
Scheduled annual or biennial inspection programs track envelope condition over time, supporting reserve fund planning and proactive maintenance.

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.

Roof Inspection questions for Don Mills.
Residential inspections start at $350, covering the membrane surface, seams, penetrations, drainage, and moisture readings, with a written report and a remaining life estimate. Core sampling is included where the readings warrant it. Larger apartment and institutional roofs are quoted by area before booking.
It is a small section cut out of the membrane and the layers below so we can see the assembly directly, then properly sealed afterwards. It answers the one question that decides everything on an older flat roof: whether the substrate underneath has taken moisture. Nothing visible from the surface reliably tells you that.
Yes, and it is a substantial part of the work in this area. Commercial reports cover drainage performance and ponding, seam and penetration condition, and remaining service life expressed as a range a lender or a board can budget against, in a format that goes straight into a reserve fund file.
Usually within two to three business days, and faster when a condition deadline is driving it. On a flat roof property a pre purchase inspection is worth more than usual, because the cost gap between a sound membrane and a saturated one is very large and completely invisible from the ground.
Yes. Underwriters ask for condition evidence more often each year, and on a flat roof they are right to. What satisfies the request is dated photographs, moisture data, and an assessment tied to specific elements rather than a general opinion.
Annually is reasonable on a membrane past the halfway point of its expected life, and every two years before that. Flat roofs give less warning than sloped ones, because there is no gradual visible decline to watch, so the inspection is doing work that observation cannot.
A flat roof inspection is a genuinely different exercise from a sloped one, because the thing that decides the roof's future is under the membrane rather than on it. A surface can look weathered and have years left, or look acceptable and be sitting over a saturated substrate that has been taking water for three seasons.
So the inspection here covers seams and penetrations individually, checks the drainage path and every low spot for evidence of ponding, takes moisture readings across the field, and where the readings warrant it takes a core sample to see the assembly directly. The written report follows within 24 hours.
What the Surface Will Not Tell You
The most expensive mistake on a flat roof is judging it by appearance. Membrane that looks tired can be perfectly serviceable, and membrane that looks fine can be sitting over sodden insulation that has been quietly adding load and losing thermal value for years.
Moisture readings and, where warranted, a core sample are the only way to know. That is why our inspections here include them as standard rather than as an upgrade, and it is why a walk around from a ladder is not an inspection on a building of this kind.
Planning a Membrane Replacement
Membrane roofs give less warning than shingle roofs. There is no gradual shedding of granules to watch, no visible curling, and often no interior symptom at all until the failure is well advanced. By the time a Don Mills owner has a stain on a ceiling, the assembly above it has usually been wet for some time.
The practical answer is to inspect on a schedule rather than on a symptom, and to use the remaining life estimate to choose the replacement date rather than have it chosen by a storm. On a flat roof that difference is worth more than it is anywhere else.
