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 York.
Starting at $350, including a written report with dated photos. The exact fee depends on how much roof there is to cover, so a house with a flat rear addition and two chimneys, or a storefront flat roof, is priced when you book, and that figure is in writing before anyone climbs a ladder.
Typically 2 to 3 business days from your call. Your written report is out no more than 24 hours after the inspection, so mention your condition deadline when you book and we will work the date back from it.
Yes, commercial flat-roof inspections are available along Eglinton, Weston Road, Keele, and the rest of York's retail strips. We check seams, penetrations, drains, and parapet flashing, and use thermal and moisture scanning to find wet insulation that the surface hides.
Yes, our reports include the condition detail insurers require. A dated record showing the roof was sound before a storm is the strongest evidence a York owner can have when an adjuster asks whether the damage is new or long-standing.
Both. Scheduled inspection programs are available for one rented semi as well as a portfolio, and for a small York landlord with a house or two a yearly visit is often the cheapest way to avoid a mid-winter tenant call about a ceiling stain.
The shared elements, explicitly and separately. Whether the covering is continuous across the party wall or properly terminated, the condition of the shared parapet including its cap and coping, the step flashing at the party wall junction, and how the shared eavestrough and downspouts drain. Each gets its own rating. We also state plainly where a future repair is likely to require the adjoining owner's participation, because that is a real cost and coordination risk a buyer should price in rather than discover.
We count them at the gable edges, around vents and stacks, and where the shingles stop against a parapet or a dormer wall. Two layers is as far as anyone should go, so a roof already wearing a second one will have to be stripped right down to the boards next time, and that costs noticeably more. On a York house built between the wars it also means nobody has seen those boards in decades, so some rotten decking under the tear-off is a real possibility and belongs in the price you offer.
Where the assessment calls for it, yes, and on a patched York commercial roof it is usually the finding that matters most. The surface tells you very little about whether water has already saturated the insulation and reached the deck. Thermal imaging maps the likely wet areas, then cores confirm it at representative points. A dry assembly with localised seam failures is worth repairing. A saturated one needs replacement, and knowing which you have changes a budget by an order of magnitude.
Increasingly yes, because carriers have tightened what they will write on older roofs and several now ask for documented condition or refuse coverage past a certain age. A current report with photographs, condition ratings, and a stated remaining useful life is what satisfies that request. It is also what supports an argument that a roof is well maintained rather than simply old, which is the distinction that decides some renewals.
Typically an annual or biennial cycle across the portfolio, timed for late summer so any work lands before winter, with a consistent report format so you can compare properties and years directly. The point is to catch the predictable items, parapet joints, flashing at shared walls, drainage, and pipe boots, while they are small repairs, and to give you a defensible maintenance record. For a landlord the saving is mostly in avoided emergency callouts and avoided tenant damage claims rather than in the roofing itself.
Pre-purchase inspections in York are valuable given the age of the housing stock. We give buyers an honest picture of what they're acquiring, remaining life, noted deficiencies, repair costs.
On a York semi the inspection has to cover things a detached-house report never raises. Whether the covering runs continuous over the party wall, what condition the shared parapet and its cap are in, and how the shared eavestrough and downspout arrangement actually drains. A buyer who does not know that a shared parapet needs rebuilding is inheriting a negotiation with a neighbour along with the house, and that belongs in the report.
Property managers and landlords benefit from annual inspection programs that track condition over time. York has a large rental sector, and for a landlord the value of an inspection programme is that it converts unpredictable emergency callouts into scheduled, budgeted work.
Pre-Purchase Inspections in York
York's housing stock is old enough that roofing condition is a real purchase consideration. Our pre-purchase reports give buyers clear information about remaining life and repair requirements.
We write honestly, if a roof has three years of life left, we say so. Each part of the roof gets its own line: the shingles on each slope, the deck and fastening, the parapet and chimney flashings, the eavestroughs and downspouts, and the porch or rear addition roof, each with a condition rating, an estimate of its remaining years, and a rough cost band. That structure is what lets a buyer negotiate against a defined figure rather than an uncertainty.
Inspecting a Semi-Detached Roof Properly
Most inspection reports treat a semi as though it were half of a detached house, and on York's housing stock that omits the elements most likely to cost the buyer money.
The covering frequently runs continuous over the party wall. The parapet at that wall, exposed on three faces and taking freeze thaw cycles harder than any other masonry on the building, serves both halves. The eavestrough and downspout arrangement is often shared. Any of those failing is a repair that may need the adjoining owner to agree and contribute.
So we assess and report each of them individually, and we state where a durable repair is likely to span both properties. A buyer who knows that before closing can price it. A buyer who finds out afterwards is negotiating from a much weaker position with a neighbour they have just met.
Annual Programs for York Landlords
York has a large rental property sector. Annual inspections help landlords stay ahead of roofing failures before they become tenant issues.
Because each year's report uses the same format as the last, a landlord can see what has changed on each house and plan the next few years of roofing spend instead of reacting to it. The recurring items on this housing stock are predictable, parapet and chimney mortar joints, flashing at party walls, pipe boots, and drainage, and each is inexpensive on a schedule and expensive after it has been running into a wall cavity for a season.
The record also matters when something does go wrong. A documented maintenance history is the difference between a defensible position and an argument, whether the counterparty is a tenant, an insurer, or a buyer.
