Niagara Storm & Roof Damage Report — 2025 Season Review
The Niagara Region took a beating in 2025. Between lake-effect blizzards, a record-setting ice storm in February, severe thunderstorms through the summer, and an early November windstorm that tore through the peninsula, it was one of the most damaging weather years for roofs in recent memory.
This report compiles publicly available weather data from Environment Canada, insurance industry trends from the Insurance Bureau of Canada (IBC), and observations from our own roofing crews who worked across the region throughout the year.
Our goal is simple: give Niagara homeowners a clear picture of what happened, which areas were affected, and what to watch for heading into 2026.
2025 By the Numbers
Here is a high-level summary of the year:
- 17 severe weather events were recorded across the Niagara Region in 2025, according to Environment Canada’s weather warnings archive
- Wind damage was the leading cause of roof repair calls, followed by ice dam leakage and hail
- February and November were the two most destructive months for roofing damage
- Insurance claims for wind and water damage in Ontario rose significantly in 2025, according to preliminary IBC data
- The average emergency roof repair cost in the Niagara Region ranged from $500 to $3,000, depending on the severity and scope of damage
The Worst Storms of 2025
February Ice Storm (February 8–10)
A prolonged freezing rain event coated the region in 15 to 25 mm of ice over three days. The weight of ice accumulation caused structural stress on older roofs, and the subsequent rapid thaw led to widespread ice dam flooding.
Most affected areas: St. Catharines (especially older neighbourhoods near downtown), Thorold, and Welland. Homes with inadequate attic insulation and ventilation were hit hardest.
Common damage: Interior water damage from ice dam backup, crushed or cracked shingles from ice weight, gutter and eavestrough damage from ice loading.
July Severe Thunderstorm (July 19)
A line of severe thunderstorms crossed the Niagara Peninsula with wind gusts exceeding 100 km/h and golf-ball-sized hail in localized areas.
Most affected areas: Niagara Falls, Fort Erie, and Niagara-on-the-Lake. Hail damage was concentrated in a narrow band through the eastern part of the region.
Common damage: Hail impact bruising and cracking on asphalt shingles (often not visible from the ground), wind-lifted shingle tabs, blown-off ridge caps, and damaged vents and flashings.
November Windstorm (November 3–4)
A powerful low-pressure system brought sustained winds of 80 to 90 km/h with gusts over 110 km/h across the entire region. This storm caused the most widespread roof damage of any single event in 2025.
Most affected areas: The entire region was impacted, but Grimsby, Lincoln, and West Lincoln — more exposed along the escarpment — saw the worst of it. Properties on elevated or exposed lots took disproportionate damage.
Common damage: Blown-off shingles (full sections, not just tabs), damaged or collapsed soffit and fascia, detached flashing, and fallen tree damage to roofs.
Damage by Type
Based on the repair and replacement projects our team completed in 2025, here is the breakdown of damage types we encountered:
| Damage Type | % of Our Repair Calls | Typical Cost Range |
|---|---|---|
| Wind damage (missing/lifted shingles) | 38% | $300–$2,500 |
| Ice dam leakage (interior water damage) | 24% | $500–$3,000 |
| Hail damage (bruised/cracked shingles) | 15% | $1,000–$5,000+ |
| Fallen tree/branch impact | 10% | $1,500–$8,000+ |
| Flashing failure after storms | 8% | $200–$1,200 |
| Structural/decking damage | 5% | $2,000–$10,000+ |
Which Niagara Cities Were Hit Hardest?
Not all parts of the region experienced the same level of damage. Geography, building age, and exposure all play a role.
High Damage
- St. Catharines — The largest city in the region with the oldest housing stock. Many homes in the older core neighbourhoods have aging roofs with limited ventilation, making them especially vulnerable to ice dams. The February ice storm hit this city particularly hard.
- Niagara Falls — Heavy hail damage from the July storm, plus significant wind damage from the November event. Tourism-area commercial properties also saw flat roof membrane damage.
- Grimsby and Lincoln — Escarpment exposure meant these communities bore the full force of the November windstorm. Homes on elevated lots lost entire sections of shingles.
Moderate Damage
- Welland — Ice dam issues were common during the February storm, particularly in post-war era homes. Wind damage was moderate compared to escarpment communities.
- Thorold — Similar pattern to Welland with ice dam damage being the primary issue.
- Fort Erie — Concentrated hail damage from the July storm, but the November windstorm tracked farther north.
Lower Damage
- Niagara-on-the-Lake — Localized hail in July, but otherwise avoided the worst of the major events.
- Pelham, Port Colborne, Wainfleet, West Lincoln — Scattered damage from individual events, but no single storm caused widespread issues.
Insurance Trends to Watch
Several insurance-related patterns emerged from the 2025 storm season:
- More insurers are requiring roof inspections before renewing policies on homes with roofs older than 15 years. If your roof is approaching that threshold, a professional roof inspection can help you stay ahead of renewal surprises.
- Deductibles for wind and hail damage are increasing. Some Ontario insurers have moved to percentage-based deductibles (typically 2 to 5% of insured value) for wind and hail claims rather than flat dollar amounts.
- Claims filed promptly are resolved faster. Homeowners who documented damage immediately and contacted their insurer within 48 hours consistently had smoother claim experiences. For a step-by-step guide, see our storm damage repair guide.
- Roof upgrades can lower premiums. Homeowners who upgraded to impact-resistant shingles or metal roofing reported premium reductions from some insurers. Our Ontario roofing and insurance guide covers this in detail.
What Niagara Homeowners Should Do Now
If your roof made it through 2025 without obvious damage, that does not necessarily mean it escaped unscathed. Hail damage in particular is often invisible from the ground but shortens the lifespan of your shingles significantly.
Here is what we recommend heading into 2026:
- Get a professional inspection. Even if you do not see visible damage, a qualified roofer can spot issues early — before they become leaks. We offer free roof inspections for Niagara homeowners.
- Check your insurance policy. Understand your deductibles, coverage limits, and any roof age restrictions before you need to file a claim.
- Address small repairs now. A few lifted shingles or a cracked flashing boot might seem minor, but they are entry points for water damage during the next storm. Small repairs now prevent expensive emergencies later.
- Consider upgrading aging roofs. If your roof is over 20 years old and took damage in 2025, it may be more cost-effective to replace it than to keep patching. Use our roof cost calculator to get a ballpark estimate.
Preparing Your Roof for 2026
Spring is the best time to address storm damage and prepare for the next cycle. Our seasonal roof maintenance checklist covers exactly what to do each season to keep your roof in top condition.
