Contain then diagnose
We contain the water intrusion first, then diagnose the full failure mode. Speed and accuracy, not just one or the other.
Document before covering
We photograph and document all storm damage before applying temporary protection. That documentation matters for insurance claims.
One call, both phases
Our vehicles are stocked for both temporary containment and permanent repair. Many emergency calls end with a permanent fix on the same visit.

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.

Emergency Roof Repair questions for Hamilton.
Typically 60 to 90 minutes, dispatching from the GTA, closer to 60 for Stoney Creek and the east end, closer to 90 for Ancaster or Flamborough in bad traffic. We give you a realistic arrival window when you call, and we answer around the clock, weekends and holidays included.
Call us, then stay off the roof, wind exposure on the strip makes ladder work genuinely dangerous for homeowners. Move what you can away from the drip zone and put down containers. We'll tarp the opened area on arrival, photograph the damage for your insurer, and quote the permanent repair in writing.
Yes. Emergency containment on a Victorian roof still has to respect the roof, we secure tarps and temporary membranes without fastening through slate, original metalwork, or heritage details that would turn one repair into three. The permanent fix then gets planned with materials appropriate to the home.
We do. Hamilton's industrial corridors carry large-span flat roofs where a single membrane split can put water across thousands of square feet of inventory or equipment. We respond to commercial calls with membrane patching materials on the truck and provide documentation formatted for commercial insurers and property managers.
Yes. Containment and diagnosis happen on the same call, we trace the failure while we're up there, photograph it before covering it, and follow up with a written scope and fixed price for the permanent repair. Most Hamilton emergency repairs land in the $350 to $2,000 range once the weather clears.
If water is actively entering the house, running down a wall, dripping through a ceiling, or pooling near electrical fixtures, that's an emergency, and it matters more on the beach strip and north-facing lower city, where a single windstorm can open a large area at once. A slow stain that isn't growing, or shingle damage with no interior water, can usually wait for a scheduled visit. If you're not sure which one you have, call anyway, we'll tell you honestly over the phone.
Move anything valuable out from under the drip and set out containers to catch water. If it's safe to access the attic, a tarp weighted (not nailed) over insulation near the leak can slow the spread. Do not go onto the roof yourself, beach-strip wind exposure and escarpment-brow ice make Hamilton roofs genuinely dangerous to walk in storm conditions, and on a century home you can do real damage to slate or original flashing by improvising a fix. We arrive with proper tarps and fastening methods that won't create a second problem.
From the ground, look for shingles in the yard, granules collecting in downspouts, and lifted or creased tabs along eaves and rakes, the beach strip and north-facing lower city take the worst of lake-effect wind and show damage first. Inside, check ceilings near exterior walls and around chimneys for fresh staining. If you see any of that, call us before the next rain rather than after; a small opening left through one more storm turns into a much larger repair.
Sudden wind and impact damage is typically covered, and Hamilton's wind exposure along the beach strip and lower city makes these claims routine rather than exceptional. What insurers push back on is damage they can argue was gradual wear rather than storm-caused, which is exactly why we photograph and document the failure before we cover it, in a format built for the claims process rather than a casual snapshot.
Start with documentation from the first visit, dated photos of the failure point, a written description of what happened and when, and our assessment of whether the damage is isolated or affects the whole roof's serviceability. Adjusters approve full replacements fastest when the report clearly separates storm-caused damage from the roof's pre-existing age and condition, so we're specific about which is which rather than blurring the two to inflate a claim.
Hamilton's emergency calls follow its weather. Lake-effect wind hits the beach strip and the north-facing lower city hardest, lifting shingles and driving rain under courses that would hold anywhere else. Freeze-thaw cycles work at the complex valleys and chimney flashings on century homes, and ice off the escarpment brow catches Mountain-edge properties every winter. When a roof fails actively, water through a ceiling, down a wall, into a panel, the sequence is always the same: stop the water, protect the interior, document everything.
Hamilton is in our extended zone, so we're honest about response time: typically 60 to 90 minutes rather than the 60 minutes we commit to inside the GTA core. We arrive carrying materials for both shingle and membrane emergencies, which means the temporary protection goes on during the first visit, not after a second trip. Photos and a written failure report come standard, your insurer will want them, and so will you.
Built for Hamilton Weather: Wind, Ice, and the Escarpment
Hamilton takes weather from two directions at once. Lake Ontario drives wind and horizontal rain into the beach strip, the North End, and the lower city's exposed streets, the kind of wind that peels back shingle courses and finds every aging flashing. Meanwhile the escarpment makes its own microclimate: brow-edge properties on the Mountain ice up earlier and harder than streets two blocks back, and meltwater off the rock face keeps lower-city roofs and foundations wet long after the storm passes.
We plan emergency response around those patterns. After a major wind event we expect clusters of calls along the strip and the north-facing streets, and we prioritize active interior leaks over cosmetic damage. Every visit produces the same output: water stopped, damage photographed before it's covered, and a written report that holds up with your insurance adjuster.
What Happens After We Leave
An emergency tarp is a promise, not a repair. Within a day of the emergency call you'll have our written diagnosis, what failed, why it failed, and what the permanent fix involves, with a fixed price attached. If the damage is claim-worthy, the photo documentation from the first visit is already in the format adjusters ask for, which matters in Hamilton where wind claims are routine and poorly documented ones stall.
We schedule the permanent repair as soon as weather allows, and the same company that answered the emergency call does the follow-through, rather than handing you to a second crew that has to rediscover the problem. That continuity is most valuable on Hamilton's older housing, where the emergency failure is often the visible end of a longer story the roof has been telling for years. We read the whole story and fix the cause, not just the chapter that got your ceiling wet.
We also cover nearby cities.
