Shingles fail one at a time before they fail all at once.
Targeted shingle repair across the GTA. We match your material and fix the failed zone, not the whole roof.
Shingle failures we repair and match.
We fix the failed zone, source matched materials, and leave the rest of the roof alone.
Missing & Blown-Off Shingles
Curling & Cupping
Granule Loss
Cracked & Split Shingles
Wind-Lifted & Re-Sealed Shingles
Valley & Ridge Cap Failures
Missing & Blown-Off Shingles
Wind & storm damage
A single missing shingle exposes the deck to rain. We replace with matched material and seal the zone.
Curling & Cupping
Age & ventilation failure
Shingles curl when heat builds under them, often a ventilation problem. We replace the curled zone and assess airflow.
Granule Loss
Aging & hail impact
Bald shingles degrade fast. Heavy loss in one zone usually means hail; uniform loss means age. Both need action.
Cracked & Split Shingles
Freeze-thaw & age
Toronto winters crack shingles that have lost flexibility, a direct path for water. We replace the cracked field and inspect surrounding courses.
Wind-Lifted & Re-Sealed Shingles
Partial displacement
Lifted shingles often re-seal in summer heat, then fall off the next winter. We reseal immediately and check every nail in the affected zone.
Valley & Ridge Cap Failures
High-wear zones
Valleys handle the most water; ridge caps take the most wind. Both fail before field shingles, we repair them as targeted jobs.
A few missing shingles today is a water damage claim tomorrow, call us first.

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.

Shingle repair questions.
Targeted shingle repairs typically run $275-$1,200. Replacing a small section after storm damage (10-30 shingles) runs $275-$600. Larger zone replacements involving deck repair or re-flashing a valley run $600-$1,200+. We provide a written estimate with photos before touching anything.
Yes, provided the surrounding shingles are still structurally sound and the deck beneath is undamaged. We replace the failed zone with matched material. The caveat: if the roof is 20+ years old with widespread granule loss or cracking, a full replacement may make more financial sense than repeated patch calls.
Storm events, wind, hail, falling objects, are typically covered under standard Ontario home insurance policies. Gradual wear and tear is not. A single wind event that blows off shingles is generally a covered claim. Document the damage immediately and call us, we write inspection reports suited for insurance submissions.
Standard 3-tab shingles: 15-20 years in Toronto's climate. Architectural (dimensional) shingles: 25-30 years. Both age faster in Toronto than warmer climates due to freeze-thaw cycling and the thermal shock of -20°C winters followed by +35°C summers. Annual spring inspection catches granule loss and cracking before they become leaks.
Repair is right if the failure is isolated to a zone, the deck is sound, and the remaining shingles have 8+ years of life. Replacement makes sense when granule loss is widespread, shingles are curling broadly, multiple zones are failing, or the roof is past 25 years. We walk the entire roof and give you an honest assessment, not a sales pitch.
What Toronto Homeowners Ask About Shingle Repairs.
The questions people search most, answered honestly by 25-year GTA roofers.
Targeted shingle repairs in the GTA typically run $275-$1,200. Replacing a handful of missing or blown-off tabs runs $275-$500. Larger zone replacements, 30+ shingles plus re-sealing or flashing, run $600-$1,200. We provide a written estimate before work starts; you only pay for what's actually broken.
Almost always cheaper to repair in the near term, $500 vs. $12,000-$20,000 for a full re-roof. Repair is the right choice when the damage is isolated and the surrounding shingles still have life. Repair becomes a bad investment when you're patching a 25-year-old roof that will need replacing in 2-3 years regardless, at that point replacement pencils out better over a 5-year horizon.
Minor repairs, replacing individual shingles or a small section, generally do not require a permit in Toronto. Full roof replacements (stripping and re-shingling) typically do require a building permit from the City of Toronto or the relevant municipality. Your contractor should know the threshold and pull the permit where required; always ask before work begins.
Yes, storm damage (wind, hail, falling objects) is a covered peril under most standard Ontario home insurance policies. Gradual wear, age deterioration, and deferred maintenance are excluded. If a single storm event caused the shingle damage, it is very likely covered. Document with photos and timestamps immediately after the event.

Repair becomes a bad investment when you're patching a 25-year-old roof that will need replacing in 2-3 years regardless, at that point replacement pencils out better over a 5-year horizon.

- Minor repairs, replacing individual shingles or a small section, generally do not require a permit in Toronto. Full roof replacements (stripping and re-shingling) typically do require a building permit from the City of Toronto or the relevant municipality. Your contractor should know the threshold and pull the permit where required; always ask before work begins.
- Does Ontario home insurance cover shingle repair after a storm?
- Yes, storm damage (wind, hail, falling objects) is a covered peril under most standard Ontario home insurance policies. Gradual wear, age deterioration, and deferred maintenance are excluded. If a single storm event caused the shingle damage, it is very likely covered. Document with photos and timestamps immediately after the event.
- How do I file an insurance claim for storm shingle damage in Toronto?
- Take timestamped photos of damaged shingles immediately, ideally before any temporary repair. Call your insurer within 24-48 hours to report the claim. Have a roofing contractor do a written inspection, we provide reports with photos, measurements, and the cause of damage, which gives your claim the best chance of approval. Avoid permanent repair until your insurer sends an adjuster unless active water intrusion forces your hand.
- Will my insurance company pay for full roof replacement if only some shingles are damaged?
- Possibly, if the damaged shingles are from a discontinued product that can no longer be matched, insurers in Ontario sometimes approve full replacement rather than a patchy repair. This is adjuster-dependent. We document the material and the extent of damage clearly, which positions you to argue for matching where warranted.
- What should I do immediately after wind removes shingles from my roof?
- Protect the exposed deck from rain first: if you can safely place a tarp over the exposed zone and secure it with boards, do so. Take photos for insurance. Then call a roofer, don't wait. Every hour of an exposed deck in Toronto weather is water working into the OSB and framing below. We offer same-day storm damage response.
- How can I tell if my shingles were damaged by hail?
- Hail damage on asphalt shingles shows as circular dark spots where granules were knocked off, they look like random bruises across the surface. Nearby soft surfaces (aluminum flashing, soffits, AC fins) will also show dents if hail was large enough to damage shingles. Granule accumulation in gutters above the seasonal norm is another indicator. Hail damage is often invisible from the ground, a roof inspection is the only reliable assessment.
- How quickly do I need to repair shingles after a storm in Toronto?
- Within 48-72 hours for any zone where the deck is exposed. Toronto's weather forecast is rarely friendly after a storm, another rain event typically follows within days. An exposed OSB deck absorbs moisture rapidly, and once the deck is wet, you're dealing with a much larger repair than a few shingles. Emergency tarp and same-day repair is the right call.
- How long do asphalt shingles last in Toronto's climate?
- Standard 3-tab shingles last 15-20 years under Toronto conditions. Architectural/dimensional shingles are rated 25-30 years, but climate stress in the GTA, freeze-thaw cycling, thermal shock between winter and summer extremes, and periodic hail, shortens real-world life relative to warmer climates. A roof installed in 1998 that has never been inspected is due for a professional assessment.
- What are the signs that my shingle roof needs replacing rather than repairing?
- Widespread granule loss visible from the ground (gutters full of granules every spring), broad cupping or curling across multiple roof faces, visible sagging of the deck, more than two or three repairs in the last five years, or a roof age past 25 years. If you are seeing two or more of these, a full replacement assessment makes sense.
- Does the Ontario climate shorten shingle roof lifespan?
- Yes, meaningfully. Toronto's climate is harder on shingles than warmer parts of North America because of the frequency of freeze-thaw cycles, the GTA typically crosses 0°C 50-70 times per winter. Each cycle stresses the granule bond and the asphalt flexibility. Shingles rated for 30 years in Texas perform closer to 22-25 years in Toronto under normal conditions.
- Can shingles be repaired in winter in Toronto?
- Yes, with conditions. Shingle adhesive strips require temperatures above -5°C to bond properly without hand-sealing. For emergency repairs in colder weather, we hand-seal each tab with roofing cement, which works reliably at cold temperatures. Non-emergency repairs in January and February may be better scheduled for a warmer week rather than done in extreme cold.
- Why do shingles blow off in Toronto winters?
- Wind events are more frequent and stronger in Toronto's winter months. More importantly, shingles lose flexibility and adhesion in cold temperatures, a tab that is sealed in summer can separate when it gets cold and stiff, then a wind gust catches it. Architectural shingles bond better than 3-tab in wind due to their weight and seal strip area.
- What is ice damming and how does it damage shingles?
- An ice dam forms when heat escaping through the attic melts roof snow, which runs down to the cold eaves and refreezes. As the dam builds, backed-up meltwater is forced under shingle laps, the direction shingles are not designed to repel. The fix is attic insulation and ventilation, not just clearing the ice; improper ice removal also damages shingles directly.
- Can I clear ice from my shingles myself without damaging them?
- Use a roof rake from the ground, extending 3-4 feet up the slope from the eave, to clear snow before it refreezes. Never chip ice directly off shingles; the impact cracks the brittle shingle surface in winter temperatures and removes granules. Calcium chloride in mesh socks laid across the eave can melt channels in an existing ice dam without the physical damage of chipping.
