I emailed at 4 a.m. and spoke with someone that same day. Estimate and completed work all within one day. Pricing was fair, work was excellent.
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.

Roof Repair questions for Richmond Hill.
Localized repairs run $350 to $2,000 depending on the failure and the access, with rebuilt flashing at a wall intersection toward the upper end because it involves working into the veneer. Full replacement on a typical Richmond Hill home runs $9,000 to $22,000, and larger estate rooflines above that.
Frequently, yes, and it is the single most common thing we find here. Step flashing that was reused, undersized, or never properly woven into the brick or stone veneer will pass a final inspection and leak a decade later. We can usually tell within one inspection whether you are looking at an installation defect or ordinary wear.
Yes, and on this housing stock it is regular work. Dead valleys collect water and debris rather than shedding them, so they need a membrane detail rather than shingles alone, and they need enough fall to actually drain. Rebuilding that detail properly is usually the entire fix.
Always, itemized and after the diagnosis rather than before it. The estimate names what failed and what the repair involves, so you can compare it against anybody else's proposal on substance rather than on the total at the bottom.
Yes. Shingle work covers the residential stock, and the flat membrane work covers the retail and office buildings through the Yonge and Major Mackenzie corridors as well as the flat sections over garages and additions on some of the housing. They are different trades and we run both.
Flashing at wall and chimney intersections, by a wide margin, followed by dead valleys and failed pipe boots. Field failures on the shingles themselves are the minority here because the housing is younger than the boroughs to the south. That is why a replacement quote given from a driveway is so often the wrong answer.
Roof repair in Richmond Hill is dominated by one failure family. The large homes built through the 1990s and 2000s carry brick and stone veneer meeting roof planes at many points, and the step flashing at those junctions was frequently installed quickly, undersized, or simply laid against the veneer rather than woven into it. Water gets behind the cladding and appears on a ceiling some distance away.
The second family is the roofline itself. Ambitious designs produce dead valleys, dormer sidewalls, and chimney saddles where water slows down and finds any weakness. Both families are repairable at the detail without touching the field of the roof, which is why we open the intersection before anyone talks about replacement.
Installation Defects Versus End of Life
These two look identical to a homeowner and cost very different amounts to fix. A roof at the end of its life has failed broadly: granule loss across the field, sealant strips gone, multiple pipe boots cracked, and a deck that has taken moisture. An installation defect is local: one wall intersection, one valley, one chimney, with sound material all around it.
On Richmond Hill's construction era the second is far more common than the first, and the industry default of quoting replacement does owners real financial harm. We open the suspect detail, photograph what is behind it, and put the finding in writing before proposing anything.
Written Diagnosis on Every Repair
Every repair produces a written report: the failure described by mechanism, dated photographs of the condition before and after, the materials used, and anything we noticed that will need attention later. No verbal only assessments and no scope that grows once a crew is on the roof.
On a house still within reach of its builder warranty period, that documentation occasionally does more than record the repair. A flashing defect photographed and described properly is evidence, and owners have used our reports to pursue the original builder rather than absorbing the cost themselves.
