Pickering runs from the Frenchman's Bay shoreline through Liverpool, Dunbarton and Amberlea to the new streets of Duffin Heights and Seaton, with rural hamlets north of them. We read each roof by its decade and its exposure to the lake, then back that reading with honest diagnosis and permanent repairs.

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.
“Pickering's lakeside streets, valley lots and brand-new subdivisions each give a roof a different reason to fail, so the address tells us where to start looking. We still climb up, go into the attic and record what we find, because a Pickering owner deserves a written reason before being asked to spend money.”

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 Pickering. If you don't see your neighbourhood listed, we almost certainly cover it.
Yes. Our Pickering area runs from Bay Ridges and West Shore on the lake through Liverpool, Amberlea and Duffin Heights, then north across Seaton to the hamlets around Claremont and Whitevale. The new Seaton streets and the rural roads beyond them get the same scheduling and the same emergency response as the south end.
Expect a roof on its second, possibly third, covering, much like the same era of house in eastern Scarborough, with a chimney that has been sealed more than once. We check the deck from the attic before quoting, find out whether an older layer was left underneath, and price the flashing to be replaced properly rather than coated with more sealant.
Yes, within 60 minutes anywhere in Pickering, day or night. The crew brings tarps, membrane and flashing to stop the water, photographs the damage before it is covered so your insurer sees it as it was, and makes the permanent repair that night when it can be done safely.
Yes, from the 1960s foundations near the lake to the poured walls in Duffin Heights and Seaton. We trace the water first, to a crack, a window well, blocked weeping tile or seepage under the slab, and then match the fix to it, whether that is crack injection, a sump pump, drainage work or a full interior or exterior system.
Yes. We walk the roof where it is safe, fly a drone over steep or fragile slopes, look into the attic from the hatch and send a written report with dated photos within 24 hours, which fits most condition periods. It separates what needs attention now from what can wait, so you negotiate on facts.
Yes. We repair, inspect and maintain flat commercial roofs on Pickering plazas, offices, industrial units and multi-residential buildings, working with the membranes already in place, including modified bitumen, TPO and EPDM. Most flat-roof leaks start at seams, drains, parapet flashing or rooftop unit curbs, so every job begins with a written report locating the entry point, and scheduled maintenance inspections catch blocked drains and open seams before they reach a tenant's ceiling.
Yes. Farmhouses and outbuildings around Claremont and Whitevale often combine steep gables, board sheathing, old chimneys and more than one past roofing material, and they reward a careful survey before any quote. We match materials where the house calls for it, and on a designated heritage property we confirm what the designation permits before suggesting a change.
Pickering is spread across more ground than most of its neighbours, from lakefront lots on Frenchman's Bay to townhouse rows in Seaton and farm properties past Highway 7, and a roofing company in Pickering has to be comfortable with all of it. On the south end we expect repair history, older chimneys and lake wear. In Duffin Heights and Seaton we look for installation shortcuts on roofs that should have years left. Either way the visit ends the same: a written diagnosis, dated photos and an estimate you can compare, with nothing quoted over the phone.
When you call roofers in Pickering, a few questions sort them quickly. Will they go into the attic, or only look from the ladder? Will they show you, in photos, where the water is getting in? Can they handle the flat roof over the garage or the plaza unit as well as the shingles? Will the warranty be in writing and name the system being installed? We answer yes to each, and we would rather lose a job than guess at a price by phone.
Pickering's older half is in the south. Bay Ridges and West Shore grew up around Frenchman's Bay, and Rosebank, Liverpool and Dunbarton filled in through the 1960s and 70s with brick bungalows, back-splits and two-storey homes much like the housing across the Rouge in eastern Scarborough. Nearly all of them are on a second or third roof, with a brick chimney or two and years of earlier patching that we read carefully before we change anything.
Amberlea, Highbush and Brock Ridge came in the decades after, and Duffin Heights and Seaton are the newest, with much of Seaton still being built. On the youngest roofs the trouble is rarely age. It is how the roof was put on: the flashing at a wall, the seal around a vent, the insulation pushed tight against the soffits. North of the new subdivisions, hamlets such as Claremont and Whitevale keep older farmhouses with steep roofs, board sheathing and aging chimneys, which call for a slower and more careful hand.
Frenchman's Bay and the open shoreline give south Pickering a rougher roof climate than streets a few kilometres inland. Wind off Lake Ontario drives rain sideways under shingle edges and into vents, and the steady damp weathers flashing and sealant on lake-facing slopes first. Inland, the Rouge and Duffins Creek valleys trade wind for trees: limbs overhanging the roof, needles and leaves settling in the valleys, and shade that keeps north slopes wet. Lower ground near the bay and the creek mouths also holds groundwater closer to the basement floor, most of all during the spring melt.
We work across Pickering on roofs and foundations alike, with leak repairs and reroofs, chimney reflashing, standing seam metal, and flat and commercial roofing for the Kingston Road plazas, the offices around Pickering Town Centre and the Brock Road industrial units. For foundations we handle basement waterproofing, injected crack repair, sump pits and pumps, and lot drainage, plus balcony and parking deck waterproofing on condo buildings. Emergency tarping is available day and night, and inspections come with drone, thermal and moisture readings, each one followed by a written report.
