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.

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 Rosedale.
Yes, including nail peg condition, slate hardness assessment, and estimated years to major repair requirement.
Starting at $450 to $600 depending on size and complexity, with the written report included. A large house with several slate slopes, flat sections behind parapets, and multiple chimneys takes longer and is priced accordingly, and we confirm the fee in writing before the visit is booked.
Yes, our reports are written to meet these standards. Each one states what was inspected, how it was reached, what was found, and a remaining useful life for each component, with dated photographs, so a lender, appraiser, or estate trustee can rely on it without having been on the roof.
Yes, full masonry-roof interface assessment is included. On a Rosedale house that covers every chimney, parapet, and dormer cheek: the step flashing, the counterflashing and the mortar joint holding it, the chimney cap, and any spot where an earlier repair swapped let-in copper for sealant.
We can usually be on a Rosedale roof 2 to 3 business days after you call, and the written report is in your hands no more than 24 hours after the visit. Buying on a conditional offer? Give us the condition date when you call, and the visit is set to leave you time to use the report in negotiation.
With hook ladders and load-spreading boards for physical access where the structure allows, and with drone survey and thermal imaging for the areas where putting weight on brittle material would cause the damage we were sent to find. On the accessible sections the assessment is hands on: testing individual slates for delamination and hardness, checking whether they are held or merely resting, and examining the fastening condition at the head where corrosion actually occurs. A report written without any of that is an opinion about a roof, not an inspection of one.
It separates the roof into its components and gives each one a remaining useful life, because on a heritage roof they diverge sharply. The slate might have forty years, the copper valleys eight, the chimney counterflashing none, and the fascia board behind a failed gutter lining might already be gone. The findings are ranked by severity, each with a time horizon and a cost band, and the report draws a clear line between what needs doing this season and what can be planned for later. That structure is what makes the report usable in a negotiation.
Often it is worth more, not less. New covering on a heritage house is exactly where we find work done cheaply over problems that were never addressed: fresh material laid over failed sheathing, counterflashing replaced with sealant rather than let back into the mortar, valleys shortcut, ventilation ignored so the next ice dam is guaranteed. A new covering changes where we look first. It is no reason to skip the look.
Yes, and they usually deserve the most attention. Many of these houses have flat or very low sloped areas behind parapets, over bays, and on later additions, and a flat roof membrane fails differently from a sloped roof beside it. When the readings justify it we cut small cores to see whether water has soaked the insulation and reached the deck, which decides whether the section needs a new surface or a full rebuild. Thermal imaging maps the wet areas first so the cores are cut where they answer something.
Yes, annual or biennial, and on heritage roofing it is the intervention with the best return. These roofs fail slowly and at predictable points, so a scheduled look at the valleys, the chimney flashings, and the eaves catches a solder seam or an eroded mortar joint while it is a small repair rather than after it has been feeding a wall cavity for two seasons. Consistent year over year reporting also builds a documented condition history, which is worth having in an estate file or at sale.
Pre-purchase inspections on Rosedale properties are high-stakes, these are among Toronto's most significant residential transactions. Our inspection reports assess heritage roofing systems with the material-specific depth these purchases require.
A general home inspection will not answer the question a Rosedale buyer actually needs answered. Most look from the lawn or from a ladder at the gutter line, and from there a slate or tile roof with forty good years ahead looks exactly like one whose nails have rusted through and will start dropping pieces within a couple of winters. Those two roofs look the same from the driveway and differ by a six figure sum.
Estate managers, real estate lawyers, and lenders all use our Rosedale inspection reports for property transactions, which is why the reports are written to stand on their own: what was inspected, what was found, what it means, and what it is likely to cost within a stated horizon.
Pre-Purchase Inspections for Rosedale Properties
A Rosedale home purchase is one of the most significant residential real estate transactions in Canada. The roofing assessment needs to match the importance of the transaction, physical access, material-specific analysis, and a written report that properly informs the buyer and their advisors.
We provide the inspection depth these transactions require. In practice the most valuable thing a report does at this stage is convert an unknown into a number with a date on it. A buyer who knows the copper valleys need replacing within a decade and the slate does not can negotiate against a defined figure. A buyer told only that the roof is old is negotiating against a fear, which serves neither side of the transaction.
Assessing Heritage Materials Component by Component
The central discipline of inspecting a Rosedale roof is refusing to give the roof a single verdict. Slate, the fastenings holding it, the sheathing behind it, the copper carrying water off it, and the masonry it dies into all age at different rates, and the failure of any one of them will be experienced by the owner as a leak.
So each is assessed and reported separately, with its own remaining life and its own recommendation. We test slate for hardness and delamination, check fastening condition rather than assuming it from the material's age, examine soldered seams in valleys and gutter linings where thermal movement concentrates, and inspect every point at which the roof meets a wall or chimney for step flashing and counterflashing that has been compromised or replaced with sealant.
The result tells you which parts of an eighty year old roof are genuinely near the end and which have decades left, which is the information that prevents an unnecessary full roof replacement on a serviceable heritage roof.
Estate and Ongoing Inspection Programs
Rosedale property owners and estate managers often benefit from regular inspection programs that track the condition of heritage roofing systems over time.
Our inspection programs for Rosedale provide consistent annual or biennial condition assessment with professional reports. The value compounds: the second report is more useful than the first because it shows rate of change, and the fifth makes it possible to plan and budget replacement of a component before it fails rather than after. For trustees and estate managers responsible for a property they do not live in, that documented history is also the defensible record that the asset has been maintained.
We also cover nearby cities.
