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 Markham.
A residential inspection starts at $350 and includes getting on the roof, going into the attic wherever there is a hatch, and a written report with photographs and an estimate of remaining life. A Unionville or Markham Village roof takes longer because each material has to be judged on its own terms, so we quote those by scope before you book.
Usually not, because a general home inspector tends to look at the roof from the ground or the top of a ladder and record a rough age. When the next roof on that house will cost $9,000 to $22,000, you want someone walking it, checking the deck, the flashings, and the attic ventilation, and committing a remaining life figure to paper while your condition period is still open.
Because in Markham's subdivision housing the attic is often where the roof's problem starts. We check whether later insulation has buried the soffit vents, look at the nail tips for frost or water staining that points to condensation rather than a leak, and record intake and exhaust ventilation separately. A roof that is failing early is usually telling us something about the attic below it.
Usually within two to three business days of booking, and sooner when a closing date is forcing the pace, so give us the deadline when you call and we will plan backwards from it. The written report reaches you within 24 hours of the visit, early enough to change what you offer or what you ask the seller to fix.
Yes, and those reports are built differently from a house report: they cover how well the roof drains and where it ponds, the state of the membrane seams and every penetration, and a remaining service life given as a range a lender or condo board can plan a budget around. For a building with several roofs we keep the same format each year, so the reports can be compared side by side.
Partly. On steep heritage roofs and on tall commercial buildings where climbing adds risk without adding information, we fly a drone and then check anything it flags up close. What it cannot do is find a soft deck, a loose flashing, or a waterlogged membrane, so the drone supplements the hands on inspection rather than replacing it.
A Markham roof inspection has to answer an era specific question. For a Berczy, Cornell, or Cathedraltown house the question is how much life the original builder grade shingles have left, which we judge from the sealant bond, the nail line, granule loss, and the pipe boots rather than from the years printed on a warranty. For a postwar house in Milliken or German Mills it is what lies under the current roof, and whether the deck was stripped and checked the last time the house was reroofed or simply covered over.
On heritage property in Unionville and Markham Village the question changes entirely. Our report on those buildings identifies each roofing material by type and grade, concentrates on the chimneys, valleys, and wall junctions where they actually leak, and spells out what the next repair will involve, since that governs its cost and the short list of trades able to do it.
Pre-Purchase Inspections in Markham
The resale stock in Berczy, Cathedraltown, and Cornell went up largely in the 1990s and 2000s, so the roof on a house for sale is often right at its first replacement point, and offers in Markham rarely wait long. A general home inspection tends to describe the roof from the ground in a sentence, which is not enough information to waive a condition against.
Our report is built to be used in a negotiation. It gives remaining life with the reasoning behind it, separates the repairs needed soon from the eventual replacement, and puts a cost range beside each item. Calling a roof fair tells a buyer nothing they can act on, while saying the north facing valley should be rebuilt this year for roughly $1,400 and the rest of the roof has six to eight years left gives both sides a number to work with.
Annual Programs for Markham Property Managers
For condo corporations and commercial owners along Highway 7, an inspection is only useful if next year's can be read against this year's. Our annual reports keep the same structure and the same measurements from one visit to the next, so a board can watch a roof's condition move over time and set reserve fund contributions from that trend.
For a Highway 7 condo that trend is the whole value. A roof flagged two years ahead can be scheduled for good weather and paid for from money already budgeted, instead of replaced in a hurry after a resident reports a stained ceiling, and on the same roof that difference often runs to several thousand dollars.
