Slate, clay tile, and original copper on rooflines built between the 1920s and the 1950s. Forest Hill needs a contractor who can source matched material, not a substitute.

Active leaks anywhere in the GTA get same-day priority dispatch. We answer at 2am, including weekends and holidays.
Complete liability coverage on every job. All work is documented and you are protected from start to finish.
Inspection reports, repair documentation, and scope estimates in writing before we touch anything.
We've worked on tens of thousands of GTA buildings. We recognise failure patterns before they become emergencies.
We trace the actual failure mode before proposing a scope, and we quote what that scope requires rather than inventing urgency.
“Forest Hill work is about sourcing and technique, not volume. A slate repair is only as good as the stock it is made with, and a counter flashing is only as good as the mortar gripping it, so both get settled before anyone promises a finish date.”

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.
Rated 5 out of 5They installed a full new roof in one day. The crew worked around the house without us hardly knowing they were there.

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.

We work across all areas of Forest Hill. If you don't see your neighbourhood listed, we almost certainly cover it.
Forest Hill North and South, the Village, Chaplin Estates, and across into Cedarvale. The whole neighbourhood is small and central, so every street in it gets the same response window from our crews.
Some of it does. Toronto Building issues permits for structural roof changes and foundation alterations, while renewing a covering in the same material usually needs none. Certain houses here are listed or designated heritage properties, where exterior alterations go through an extra review, and we find out whether yours is one of them before the estimate is written.
In most cases yes, and where we cannot we say so before the work starts rather than after. If the tile on your roof has gone out of production, we take good pieces off a back or side slope to use where the repair faces the street, and the closest modern equivalent goes where nobody looks. You should choose that with your eyes open rather than find it afterwards.
A core part of the work, and never the only part. Slate, tile, and copper have been on our books since the business started in 1999, next to the flat roofing and membrane side, and doing both is what keeps the advice honest: a heritage-only firm prices every job as specialist work, and a volume firm will cheerfully put asphalt over slate.
Yes. The low-rise buildings in both villages, often with apartments or offices over the stores, mostly carry flat roofs, parapets, and rear additions rather than slate, so our flat roofing crews handle them. Work is planned around the businesses trading below, and the owner receives a written condition report with photographs.
Carefully, because broken slate and tile are heavy and sharp, and the lots here are defined by mature trees and planting close to the house. We plan how debris leaves the roof before the first piece is lifted, keep bins and ladders clear of trunks and beds, and cover paths and plantings under the work area.
Because the slate is rarely what fails first. Nails rust through long before good slate wears out, and counter flashing at a chimney or parapet works loose as the mortar around it softens, so a roof can look intact from the street while water gets in at its edges and fixings.
Forest Hill divides roughly at Eglinton. The southern half, including the Village and Chaplin Estates, holds the earliest and densest fabric, much of it 1920s and 30s on relatively tight lots with mature canopy. North of Eglinton the houses get later and the lots larger, and there is more of the 1940s and 50s stock where cedar and asphalt start to appear alongside slate.
Cedarvale to the west sits lower, running down toward the ravine, which changes the below grade picture more than it changes the roofs. Properties nearer the ravine deal with water arriving through the ground rather than sitting against the foundation.
We diagnose before anyone prices anything. On slate or tile the first task is naming what is actually up there, its type, its grade, and where it likely came from, because that decides what a repair involves and which trades can carry it out properly.
The written report names the material, the failure, and what fixing it properly requires, with photographs. On these buildings that record has a long life: the next owner, the next contractor, and the insurer all need to know what is actually on the roof, and very few properties here have that written down anywhere.
Forest Hill was developed from the 1920s through the 1950s and the roofs reflect it. Slate is common, clay tile appears on the Tudor and Norman revival houses, cedar shows up on the later stock, and original copper flashing, valleys, and downpipes are still in service on a great many properties. Almost none of it is asphalt, and the buildings that do carry asphalt usually acquired it during a replacement that should have gone differently.
Material is the constraint that shapes every job here. No two slate quarries produce stone of the same colour and thickness, and each weathers in its own way across the decades. Tile makers retire profiles, so the one on your roof may no longer be manufactured at all. Copper takes years to darken to the patina already on the house. Patch any of it with the nearest thing to hand and the mismatch stays visible from the sidewalk for good, on streets where appearance carries real weight in what a property is worth.
The other constant is where roof meets masonry. A typical Forest Hill house has a large chimney, often a parapet or two, and stone or brick walls rising through the roof planes at several points, and the counter flashing tucked into those mortar joints lets water in far more often than the slate or tile does.
Forest Hill work is about sourcing and technique, not volume. A slate repair is only as good as the stock it is made with, and a counter flashing is only as good as the mortar gripping it, so both get settled before anyone promises a finish date.
