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.
Scarborough, ON·Google

Flat roof replacement on a commercial unit. Clean, fast, no surprises on the invoice. The crew left the site cleaner than they found it.
Mississauga, ON·GuildQuality

Called after a storm damaged our roof. Someone was on site within hours, tarped everything, and had us fully repaired before the next rain.
Vaughan, ON·HomeStars
Rated 5 out of 5
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.
North York, ON·Google

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.

In Depth
Heritage Roofing in Rosedale
Rosedale's heritage roofing systems are irreplaceable in many cases. Original Welsh or Vermont slate, hand-formed copper valleys, purpose-made clay tiles, these materials are not interchangeable with modern substitutes. Proper repair requires matching original materials and methods.
We have the supplier relationships and technical knowledge to source appropriate heritage roofing materials for Rosedale properties.
Ravine-Adjacent Waterproofing in Rosedale
Rosedale's ravine system, the Don Valley and its tributaries, creates a complex groundwater environment for properties on adjacent lots. High water tables, seasonal groundwater fluctuation, and the specific soil conditions of ravine-adjacent sites require waterproofing assessment that goes beyond standard residential approaches.
We approach Rosedale waterproofing projects with the site-specific analysis they require.

About Rosedale
What we know about buildings in Rosedale.
Rosedale is one of Canada's most prestigious residential addresses. The housing stock, largely pre-1940, includes substantial stone and brick mansions with heritage roofing systems: natural slate, clay tile, elaborate copper flashing networks, and original masonry chimneys that are now 80-100 years old.
Working on Rosedale properties requires specialist material knowledge, careful site practice, and the communication skills to work with owners who have high expectations and valuable assets. A slate roof on a Rosedale mansion can represent $80,000-150,000 in material value alone. We treat every job on these properties accordingly.
Beyond the roofing, Rosedale's deep ravine-adjacent lots create specific waterproofing challenges, hydrostatic pressure from ravine slopes, high water table in low-lying areas, and aggressive groundwater conditions that require proper engineering-quality assessment.
