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 Repair questions for Woodbridge.
Same-day for active leaks anywhere in Woodbridge, and a scheduled repair is usually booked within 2 to 5 business days. If water is coming in right now, our 60-minute emergency service handles the call.
Yes. We reset slipped tiles, replace broken ones with the closest profile and colour we can source, and repair the underlayment and flashing beneath, which is usually where a tile roof actually leaks. If an exact match is no longer made, you hear that from us before the work is priced.
Shingle repair is a large share of our Woodbridge work. Wind-lifted tabs, a torn run at a rake edge or a cracked pipe boot can be repaired on their own when the rest of the roof has years left, and if it does not, we say so in writing.
On a complex roof, water that gets in at a valley or wall junction can run along a rafter, a beam or the top of a wall before it drips, so the stain may sit several metres from the entry point. That is why we trace from the roof down rather than patching whatever is directly above the stain.
Yes. Flat decks over front entrances and balconies above living space are common on Woodbridge custom homes, and they tend to fail at the door threshold, the drain and the edge where the membrane meets stucco. We repair or replace the membrane and re-detail those edges so water has somewhere to go.
Yes, EPDM, TPO and modified bitumen roofs on plazas, warehouses and industrial buildings along Highway 7 and the 400, with written reports for owners and property managers. We can schedule the work around business hours so tenants stay open.
Always, with a written diagnosis and dated photos attached and a fixed price agreed before any work begins. We do not quote a Woodbridge roof repair over the phone.
The custom homes built across Woodbridge from the 1980s onward were designed to impress from the street: hipped roofs broken up by towers and dormers, clay tile or tile-profile accents, stucco and stone walls rising into the roofline, and flat decks or porticos over the front entrance. Each of those features is a place where two materials meet and a flashing has to manage the water. When these houses leak, it is almost always at one of those meeting points, and the stain inside can appear a room or even a floor away from where the water got in.
Stucco walls are the detail we open up most often. Where a roof slope runs into a stucco wall, the step flashing and the kick-out at its lower end are hidden behind the finish, and a missing or undersized kick-out sends water into the wall instead of the gutter. In the older village core near Islington Avenue and Woodbridge Avenue the problems are more conventional: aging chimney flashing, worn pipe boots and shingles past their service life on postwar bungalows and storey-and-a-half houses. We repair each according to what it is, not what the house next door needed.
Roof Leak Repair on Woodbridge Custom Homes
Complex rooflines fail in a fairly predictable order. First the valleys, where two large slopes pour into one channel and leaves from mature trees and the Humber valley collect. Then the junctions with walls, towers and chimneys, where the flashing is only as good as its integration with the stucco or stone. Then the penetrations: skylights, vent stacks and exhaust hoods, which multiply on a large house. The shingle or tile across the open field of the roof usually outlasts all three. Knowing that order lets us check the likely entry points first and keep the repair to the detail that has actually failed.
Repair or Replace: How We Decide
On custom homes from Woodbridge's main building years the question of repair versus replacement comes up on most calls, and our answer depends on the field of the roof, not the leak. If the shingles still flex without cracking and hold their granules, a flashing or valley repair is money well spent. If whole slopes are brittle and bare, patching one leak buys a season before the next one, and we put that in writing with photographs so you can plan the replacement on your own timetable rather than in a hurry.
Commercial Flat Roofs Along Highway 7 and the 400
Large flat roofs on the plazas, warehouses and light industrial buildings along Highway 7 and the 400 leak in different places from houses. Water gets in at drains that have pulled away from the membrane, at the curbs of rooftop heating and cooling units, at seams worn by foot traffic from service trades, and wherever ponding sits for days after rain. Because water travels under a membrane before it shows, we scan for wet insulation to locate the true entry point, repair the seam or detail, and tell the owner how much of the surrounding roof has been soaked.
We also cover nearby cities.
