They installed a full new roof in one day. The crew worked around the house without us hardly knowing they were there.

North York, ON·HomeStars

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.

Etobicoke, ON·Google
Rated 5 out of 5

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
Rated 5 out of 5

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
Rated 5 out of 5

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
Rated 5 out of 5

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.

FAQ

East York roofing questions.

All of the former borough, which is smaller and more sharply bounded than most people assume: the Don Valley on the west, Victoria Park on the east, Eglinton at the top, and the Danforth along the bottom. That takes in Woodbine Heights, Old East York, O'Connor-Parkview, Pape Village, Playter Estates, Crescent Town, and Thorncliffe Park. Every one of those streets is a short run from our North York shop, so no corner of the borough waits longer than another.

Yes, through Toronto Building, which covers East York from the Toronto and East York district office. A permit is needed for structural roof changes and for foundation alterations, while stripping and replacing shingles with the same covering generally needs none. The complication here is party walls, since work affecting a shared structure can involve your neighbour's property rights as well as the city's requirements, and we raise that before quoting rather than mid-job.

Sometimes, and we would rather establish it early. A shared valley between two semis drains both roofs, and a shared chimney serves both units, so work on either can require access from next door or affect their side of the structure. When it applies we flag it on the estimate, and we are happy to explain the work to the neighbour ourselves rather than have you pass along a technical conversation secondhand.

Since the early years of the business, and it is a borough that rewards familiarity. Once you have opened up thirty of these 1930s and 40s semis you know what tends to be under the shingles, which of the original details are still doing their job, and which repairs from the 1980s are about to become your problem.

Yes. Those 1960s apartment blocks are flat-roofed buildings with nothing in common with the semis around them, so they go to our commercial membrane crews for membrane repair or replacement, balcony waterproofing, and parking deck waterproofing. Managers come away with a written condition report and dated photographs, ready to drop into the building's records.

Yes. Playter Estates predates most of East York, and its bigger houses carry more dormers, valleys, and chimney intersections than a typical semi, sometimes with original slate, cedar, or copper worth keeping. We assess and price those roofs on their own terms rather than as a larger version of the standard East York job.

We look before we price. One of our people climbs onto the roof, and up through the attic hatch if the house has one, to find the real failure, and you are sent a written estimate with dated photographs rather than a figure guessed over the phone or from the sidewalk.

In Depth

Where We Work in East York

East York is the smallest of the former boroughs and the most consistent in what it is made of. Most of it went up between the 1930s and the 1950s as semis and modest detached houses on twenty to twenty-five foot frontages, often a block at a time, so neighbouring houses tend to share the same details right down to the flashing. Woodbine Heights, Old East York, and Pape Village are the clearest examples. Playter Estates to the west is older and grander, Thorncliffe Park and Crescent Town are the exception entirely: 1960s apartment towers on a scale nothing else in the borough matches.

That uniformity is genuinely useful to a contractor. If one house on a street has lost its valley or its chimney flashing, the ones either side are rarely far behind, and that lets us tell an owner what is coming with more confidence here than in a borough built across five decades.

Roofing East York's Dense Residential Streets

East York's residential streets were built quickly in the 1930s and 40s, semi-detached and detached homes on 20 to 25 foot lots, typically with common walls and shared drainage paths. The density means that a failure at the party-wall valley affects two properties. We account for this when diagnosing and proposing repairs.

Original construction details, clay tile flashing, early asphalt saturated felt, cast iron drains, are still present in many of these homes under subsequent repair layers. We identify what's there before determining what to do.

Working on Narrow Lots

The lot width shapes the job here more than anything else. A twenty-two foot lot with a party wall down one side leaves no driveway for a bin, almost nowhere to stage material, and frequently no route to the back of the house except through it or across the neighbour's yard. Contractors who work mainly in the suburbs price East York jobs as though those constraints do not exist and then discover them on the first morning.

We plan the access before quoting: where the bin goes, whether a street occupation permit is needed, how material reaches the roof, and what the neighbour needs to be told and when. It is not glamorous and it does not appear on an estimate as a line item, but it is the difference between a three-day job and a three-day job that becomes five.

How We Work in East York

East York residents frequently tell us they've had contractors propose full replacements when targeted repairs were the right answer. We approach every East York job with that history in mind, our goal is an honest diagnosis, not a maximized invoice.

We've been on East York rooftops long enough to recognize what good condition looks like for a 1940s building versus poor condition. That context informs every recommendation we make.

About East York

What we know about buildings in East York.

East York is one of Toronto's densest residential areas, largely 1930s through 1950s construction, semi-detached and detached homes on narrow lots with party-wall situations. These buildings have specific roofing challenges: shared valley flashings between semis, original clay tile or asphalt underlayment from the construction era, and decades of accumulated repairs layered over one another.

The brick and masonry construction typical of East York introduces a secondary challenge: the interface between the roofline and the masonry parapet or chimney is a primary failure point. Counter flashings, cap flashings, and chimney repointing intersect with the roofing system in ways that require both roofing and masonry competence.

We work on East York buildings regularly. The combination of age, density, and construction type means careful diagnosis is essential before proposing any repair scope.

Semi-detached 1930s homes with shared valleys, original masonry chimneys, and decades of layered repairs require a contractor who reads the building before touching it. That's how we work in East York.
