Ontario winters are unpredictable. One moment the skies are clear, the next a sudden windstorm, snowfall, or deep freeze causes roof damage that simply can’t wait. For homeowners in Barrie, Simcoe County, Muskoka, and Parry Sound, winter roofing emergencies are stressful, but professional help is available year-round.
At JN Roofing, we know roof problems don’t pause for the weather. Our crews are trained, equipped, and certified to handle cold-weather repairs safely, efficiently, and in compliance with Ontario Building Code Part 9.26, which governs roofing performance in cold climates.
Can Roofing Work Be Done in Winter?
Yes, when handled by experienced professionals using the right materials and safety practices. While extreme cold can limit certain adhesives, JN Roofing uses Owens Corning TruDefinition Duration shingles and cold-weather-rated sealants tested for temperatures as low as -7°C.
We define extreme weather as any combination of heavy snow, freezing rain, ice buildup, or wind chills below -15°C. In those conditions, permanent repairs are postponed, but our team can still install secure temporary protection to prevent leaks or structural damage.
Every repair begins with a site inspection to evaluate temperature, surface traction, and safety. If conditions allow, our certified installers proceed immediately with the repair to minimize further damage.
Common Winter Roofing Emergencies
Cold weather brings unique challenges that can quickly compromise a roof. Understanding what to watch for helps you act before small issues turn into major ones.
1. Active Roof Leaks
A sudden ceiling stain or dripping water often means melted snow is finding a way inside. JN Roofing identifies the source, installs emergency patching, and schedules follow-up restoration once temperatures stabilize.
2. Ice Dams
Ice dams form when attic heat melts snow that refreezes along roof edges. The trapped water backs up under shingles and into ceilings. Our team safely removes ice buildup and repairs affected sections.
3. Wind and Storm Damage
Gusts over 70 km/h can tear shingles, lift flashing, or dislodge vents. We offer same-day emergency inspections to secure exposed areas and prevent further deterioration.
4. Heavy Snow Loads
Accumulated snow adds stress to rafters and sheathing. JN Roofing clears excessive buildup using specialized equipment that won’t harm your shingles or gutters.
How JN Roofing Handles Winter Repairs Safely
Safety is our first priority. Working on icy or snow-covered surfaces requires skill, experience, and the right equipment.
Our cold-weather procedures include:
- Harness systems and anchor points on every site.
- Ice-resistant footwear and insulated safety gear.
- Continuous monitoring of wind chill and surface stability.
- Use of mechanical fasteners and cold-weather adhesives that perform below freezing.
All work follows manufacturer and Building Code standards to ensure long-lasting protection even when temporary solutions are required.
Temporary vs. Permanent Fixes
During winter, the focus is to stabilize damage and prevent further water intrusion.
Temporary Repairs
These include tarping, patching, or sealing to stop active leaks. They are durable through the season but designed for short-term protection.
Permanent Repairs
When the weather warms and surfaces are dry, JN Roofing completes lasting solutions such as replacing shingles, flashing, or underlayment.
Typical Timelines:
- Response: Within 24 hours for emergencies.
- Temporary repair: Completed within 1–2 days, weather permitting.
- Full restoration: Scheduled as soon as weather conditions allow, typically within a few weeks once spring begins.

Winter roof emergencies often qualify for insurance coverage, particularly when caused by windstorms, ice buildup, or falling debris.
JN Roofing assists homeowners by:
- Providing inspection reports, damage photos, and cost estimates for claims.
- Coordinating directly with insurance adjusters to confirm repair scope.
