Roofing & Waterproofing in Whitby
Whitby holds a Victorian downtown, 1960s to 80s neighbourhoods through its middle, fast-growing subdivisions to the north and the old village of Brooklin beyond them. We judge every roof by its age, its exposure and the way it was built, then give you an honest assessment and a quality repair.

“A Victorian house off Brock Street, a 1970s split-level south of Taunton and a five-year-old Brooklin build have almost nothing in common above the ceiling, and a contractor who treats them alike will misread at least two of them. We start from the age and exposure of the house in front of us and confirm it on the roof before anything is priced.”

Luciano did not try to sell me a new roof. Appreciated the honesty — he showed up when he said he would.
Etobicoke, ON·Google

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.

FAQ
Whitby roofing questions.
Yes. We work from Port Whitby and the lakeshore through downtown and the central neighbourhoods to Williamsburg, Fallingbrook and Brooklin, including the older village core along Baldwin Street and the new subdivisions around it. Booking and emergency response work the same in Brooklin as anywhere south of the 401.
Often, on houses from the 2000s and 2010s. In north Whitby the leak tends to show up at a dormer, a second-storey wall or a garage roof tie-in, where flashing was cut short or left out, or at a vent sealed with caulking alone. We pin down the exact detail with photos, which is useful if you plan to raise it with the builder.
Yes. The phone is answered around the clock, and a crew is on site within 60 minutes anywhere from Port Whitby to Brooklin. Wind damage on the lake side and ice dam leaks in late winter are the typical Whitby calls, and both start with containment and dated photos.
Yes, across Whitby and Brooklin. We find where the water is entering first, then recommend the smallest fix that will actually stop it, which can be as modest as regrading and extending downspouts or as involved as crack injection, a sump pump or a full interior or exterior system.
Yes. We get onto the roof and into the attic, take dated photographs, and send a written report within 24 hours that separates near-term repairs from the eventual replacement, so you know what the house will need before your conditions come off.
Yes. We repair and maintain flat commercial roofs on plazas, offices and light industrial buildings along Dundas Street, Thickson Road and the 401 corridor, working with modified bitumen, EPDM and TPO membranes. For property managers we offer scheduled maintenance programs that cover drains, seams, flashings and rooftop unit curbs, with a written report and dated photos after every visit.
Yes. The older houses around downtown and Port Whitby often carry steep gables, several chimneys and more than one generation of roofing, so we survey the whole roof before quoting any part of it. Chimneys are reflashed with step and counter flashing cut into the brick joints instead of being sealed over again, and we match the existing material wherever the house calls for it.
In Depth
Roofing Contractors in Whitby for Old and New Homes
Good roofing contractors in Whitby have to switch between very different jobs in the same week: a tangle of gables and chimneys downtown, a worn second roof on a 1970s split-level, and a three-year-old Brooklin house leaking where a roof meets a wall. We treat each on its own terms. The first visit finds and photographs the cause, the written estimate explains it in plain language, and the repair is sized to the problem rather than to the biggest job we could sell.
Comparing Roofing Companies in Whitby
Two Whitby quotes for the same roof can differ widely because they describe different jobs. Check whether each one replaces the flashing or reuses it, whether it includes ice and water membrane at the eaves and valleys, whether damaged decking is priced per sheet or left vague, and whether ventilation is being corrected or ignored. Ask how the old shingles will be removed and disposed of, and get the warranty in writing with the system it covers named. Our estimates spell out each of these, so you can compare like with like.
Commercial Roofing in Whitby
Whitby's commercial corridors along Dundas, Thickson, Brock and Victoria Street hold flat-roof retail, office and light industrial buildings spanning 40 years of construction, from built-up and modified bitumen roofs to newer TPO and EPDM. We inspect, repair and maintain all of them, locating leaks with a moisture scan before cutting into a membrane, and each visit produces a written report with dated photos for owners and property managers.

About Whitby
What we know about buildings in Whitby.
Downtown Whitby grew up around the four corners of Brock and Dundas, and the streets around it still hold Victorian and early twentieth-century brick houses with steep gables, several chimneys and additions from nearly every decade since. Down at the harbour, Port Whitby mixes older cottages with newer townhouses. On houses like these a leak is usually one detail rather than the whole roof, a chimney, a valley, a dormer cheek or the seam where an addition was tied in, and we work out the repair history before we touch it.
Pringle Creek, Rolling Acres, Blue Grass Meadows and the streets either side of Thickson Road filled in from the 1960s to the 80s, and those roofs are now on a second or third covering with the problems that age brings: tired flashing, cracked vent boots, attics short of ventilation and eavestroughs that spill against the foundation. Williamsburg, Fallingbrook and the new Brooklin subdivisions near the 407 are a generation younger, and when they leak it is more often because of how the roof was installed than how long it has been up.
The Whitby shoreline is short but exposed. Around Port Whitby and the Lynde Shores marshes, wind off Lake Ontario arrives with little to slow it, lifting shingle edges and pushing rain into lake-facing vents. Brooklin, by contrast, is open country, and its young subdivisions have little tree cover to break a gust. Lynde Creek and Pringle Creek wind south through the town, and houses on the lower ground near them see more groundwater pressing on their foundations after the spring thaw.
Across Whitby we handle roof repair and replacement, chimney and flashing work, standing seam and steel roofing, and flat and commercial roofing on the plazas and light industrial buildings along Dundas Street, Thickson Road and the 401 corridor. Under the house, we waterproof basements with crack injection, sump pumps, drainage correction and full interior or exterior systems, and we repair balconies and parking decks on multi-unit buildings. A crew is on call around the clock for storm tarping, and we bring drone, thermal and moisture tools to an inspection wherever they tell us more.
