Physical access
Written reports
Material-specific assessment

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 Oshawa.
From $350 for a residential roof, with the written report and photographs included in that price. Commercial and industrial roofs are quoted by size and access.
A general home inspection covers the whole house and may only view the roof from the ground or a ladder. A roof condition assessment goes onto the roof where it is safe and into the attic, rates each component on its own and estimates remaining life, and on older Oshawa houses with layered roofs that detail often changes the price conversation.
Usually within 2 to 3 business days, and we will work to your condition deadline if it is tighter. The report arrives within 24 hours of the visit.
Yes. Flat roofs on plazas, warehouses and plants are checked for membrane wear, seam and flashing condition, drainage and ponding, and trapped moisture, with reports written for property managers, lenders and insurers.
Yes. We arrange access with the tenant or property manager, and the report is written so an owner who cannot visit can still understand the roof's condition and plan repairs from it.
Once a year is a sensible routine for older roofs and for any flat or commercial roof, plus a check after a major wind or hail storm. A younger shingle roof in the north end can go longer between visits, but an inspection before a sale or before you buy is always worthwhile.
A great deal of Oshawa's housing is 60 years old or more, and its roofs carry a long repair history that no listing will mention. A house in Central Oshawa or Vanier may have two layers of shingles, board sheathing, a chimney that has not vented anything in years, and a flat rear addition built later by someone else. A pre-purchase roof inspection in Oshawa sorts that out before you waive conditions. We check each part of the roof separately and estimate its remaining life, so you negotiate on facts rather than on the listing.
In the north end, Samac, Pinecrest, Taunton and Windfields call for a different kind of inspection. The roofs are younger and the questions are about workmanship and airflow: whether valleys and walls were flashed properly, whether the attic has enough intake at the soffits, and whether the shingles have sealed down. For landlords with rentals near the university and college, and for owners of commercial and industrial buildings, we also offer scheduled inspections with reports in a consistent format, so changes can be tracked from one visit to the next.
Pre-Purchase Roof Inspection in Oshawa: Reading an Old Roof
On a 1940s or 1950s Oshawa house, the most important questions are often out of sight. How many layers are on the deck, and will the next roof need a full tear-off? Is the sheathing boards or plywood, and has any of it softened at the eaves? Are the rafters still straight at the ridge? We answer these from the roof surface, the eaves and the attic, and the report sets out what the next reroof will involve as well as how long the current one should last. That second answer is often the one that matters most for the price.
Roof Condition Assessment for Commercial and Industrial Buildings
Oshawa's commercial and industrial stock runs from 1940s industrial buildings to recent plazas, and many of its flat roofs have been patched and re-covered over the years. A condition assessment maps the roof, records the membrane type and condition, checks each drain and penetration, and flags trapped moisture that will not show on the surface. The written report gives remaining service life as a range and separates urgent repairs from items that can be planned, which is what owners, lenders and tenants negotiating a lease need to see.
What to Expect on Inspection Day
Most residential inspections take 45 to 60 minutes on site. We walk the roof where it is safe, use a drone for steep or fragile sections, check the eaves, gutters and downspouts, then go into the attic to look for staining, daylight and ventilation problems. Findings are photographed as we go. Within 24 hours you receive the written report, with each component rated, remaining life estimated and issues ranked by urgency, and every photo keyed to the finding it supports.
We also cover nearby cities.
