Essential Roof Maintenance Tips to Protect Your Ottawa Home This Winter

Your roof is your home’s primary shield against the elements. In Ottawa, that shield takes a beating. From heavy snowfalls to flash freezes, the winter months put immense strain on your roofing system. However, a few essential maintenance steps can make the difference between a cozy, dry winter and a costly emergency.
At Stewart Roofing, we emphasize the importance of roof maintenance as an investment in your property. A well-maintained roof lasts longer, performs more efficiently, and maintains its appearance better. Here are our essential tips for protecting your home this season.
Manage the Snow Load (Safely)
Ottawa winters can dump feet of snow on us overnight. While modern roofs are designed to withstand significant weight, excessive accumulation can still be a problem, especially for older homes or flat roofs.
The National Roofing Contractors Association (NRCA) warns that six inches or more of accumulated snow can begin straining roof structures. If you feel the snow load is becoming excessive, the goal is to remove it without damaging the shingles.
- Use a Roof Rake: A telescoping rake allows you to safely remove snow from the eaves while standing on the ground.
- Leave a Layer: Never try to scrape the roof completely clean. Leave 2-3 inches of snow on the surface to avoid scraping the granules off your shingles.
- Don’t Use Sharp Tools: Never use shovels, axes, or picks. You will almost certainly damage the roofing material.
The Gutter Game: Preventing Ice Dams
Clogged gutters are the number one cause of ice dams. When leaves and debris block your eavestroughs, melting snow cannot drain away. Instead, it pools at the edge of the roof and freezes. This creates a dam that traps water behind it, forcing it under your shingles and into your attic.
- Clear Debris: Ensure your gutters are free of autumn leaves.
- Monitor Downspouts: Ensure that downspouts extend at least six feet away from your foundation to prevent basement flooding.
- Watch for Icicles: As mentioned in our repair guide, icicles are a symptom of poor drainage or heat loss. If you see them forming, it is time to investigate.
Check Your Attic Ventilation
We often think of roofing companies as only working on the outside of the house, but the inside is just as important. Your attic should be the same temperature as the outside air. If it is too warm, snow will melt and refreeze at the eaves.

- Inspect Vents: Make sure your soffit vents are not blocked by insulation. You need clear airflow from the bottom of the roof to the ridge vents at the top.
- Seal Leaks: Check for air leaks around light fixtures and plumbing stacks that may be allowing warm house air to enter the attic.
Trim Overhanging Branches
Trees can be beautiful, but in winter, they are a hazard. Heavy snow can snap branches, causing them to crash onto your roof. Even small branches rubbing against yours in the wind can dislodge the protective granules from your shingles, reducing their lifespan.
Trim any branches that hang over your roofline to prevent impact damage and reduce the amount of debris falling into your gutters.
Professional Inspections
The best way to ensure your roof is ready for winter is to have it professionally inspected. A trained eye can spot loose flashings, cracked sealants, and aging shingles that an untrained observer might miss.
