We trace first
Written reports
25+ years experience
No upsells

We trace first
Every job starts with a full trace from interior stain back to the roof. We find the source before touching anything.
Written reports
You receive a written diagnostic report with photos, suitable for insurance, lenders, and property management files.
25+ years experience
Two and a half decades on GTA roofs means we've seen every failure mode across every building type in the region.
No upsells
We don't sell replacements when repairs are appropriate. Our invoice reflects what the building actually needs.
60-min emergency
Active leaks get same-day priority dispatch, around the clock, including nights and weekends.
Permanent repairs
We use manufacturer-matched materials and test the repair before we leave. No waiting for the next rain.
“We trace the leak from the stain back to the source. That's how leaks get fixed permanently.”

Rated 5 out of 5Blue Knight was, by far, the best. Responsive, ethical, totally professional — and their crew went above and beyond at no extra charge.

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 The Beaches.
Yes, and we treat it as two separate jobs. The first is repairing what the trapped water damaged, which is usually the eave detail, the underlayment above it, and sometimes the deck. The second is finding what allowed the dam to form, which on these houses is nearly always attic ventilation and insulation rather than anything on the roof surface. Repairing only the first guarantees you will call us again next winter.
Yes, particularly the metalwork. In a high-humidity, salt-carrying environment the flashing and fastener choice matters more than the shingle choice, because the metal fails first and takes the roof with it. On lake-facing elevations we specify accordingly, and we will tell you when a cheaper option is a false economy on that side of the building.
Yes, and it is regular work in this neighbourhood. The detail on these houses is counter flashing set into a mortar joint, and the failure is usually as much about the mortar as the metal. Reseating flashing into deteriorated mortar will not hold, so the repair frequently involves repointing the affected courses first. We assess the masonry and the metalwork together rather than quoting one and discovering the other.
Localized repairs run $350 to $2,000 depending on the failure and the access, with the higher end covering rebuilt valleys and extensive flashing work. Heritage material adds to that where slate or original metalwork has to be matched rather than substituted. Every figure is written and itemized, and it follows the diagnosis rather than preceding it.
Yes, on every job as standard. The report covers the failure we identified, photographs of the condition before and after, the materials used, and anything we noticed that will need attention later. On a heritage property that record is worth keeping, since the next owner and the next contractor will both want to know what was actually done rather than guessing from the outside.
Because the water is almost certainly arriving horizontally rather than falling. A leak that appears in a driving easterly off the lake and never in ordinary heavy rain is telling you the entry point is on a vertical surface: a wall flashing, a sidewall, a soffit, or the gap behind cladding. That is diagnostic information rather than a curiosity, and it usually saves us a great deal of time finding the source.
Roof leaks in The Beaches often have contributing causes that aren't visible from the rooftop, lake-driven moisture infiltration at flashing joints, ice dam formation at eaves exacerbated by lake-effect freeze-thaw, and accelerated corrosion in metal valley liners.
The corrosion point matters more here than anywhere else we work. Valley liners, step flashing, and drip edge on a lake-facing elevation degrade faster than the same metal on the sheltered side of the same house, which means a roof can be sound on three elevations and failing on the fourth. We assess the orientations separately rather than giving the roof a single grade.
What Fails on Beaches Roofs
The failure patterns here are consistent enough to predict. Valley liners and step flashing corrode on lake-facing elevations well before the shingles above them wear out. Eave details fail from ice damming driven by attic conditions rather than by roof conditions. Chimney counter flashing works loose as the mortar it is set into deteriorates. And on the flat ground near the boardwalk, wind-driven rain finds its way in at wall and soffit junctions that a sheltered house would never test.
None of those are shingle problems, which is why a reroof quoted from the driveway so often fails to fix the leak. We trace the water to its entry point and repair that, and where the shingles genuinely are finished we say so with photographs rather than assertions.
Working on a Narrow Beach Lot
The lots here are narrow and the streets are tight, and both shape the job more than the roof does. There is often no room for a bin on the property, limited space to stage material, and no route to the rear except through the house or a neighbour's yard. Parking on a Beach street during a working day is its own problem.
We plan that before quoting rather than discovering it on the first morning: where the waste goes, how material reaches the roof, what the neighbours need to be told and when. It never appears as a line on an estimate, but it is the difference between a job that takes the days we said it would and one that quietly does not.
