What is the Impact of Heavy Snow on Flat Roofs?
Ontario winters can bring significant snowfall, which poses serious risks for flat roofs. Unlike sloped roofs, flat roofs don’t naturally shed snow, causing accumulation that can lead to structural and water-related issues.
Common Risks of Heavy Snow on Flat Roofs
1. Increased Risk of Leaks
Heavy snow accumulation puts extra pressure on your roof’s membrane. Over time, this can lead to:
- Water pooling and seepage into the building.
- Compromised roofing seams and flashing.
- Increased likelihood of interior water damage.
2. Structural Strain and Collapse
Excessive snow weight can stress a building’s framework, potentially leading to:
- Roof sagging or warping.
- Structural damage requiring costly repairs.
- In extreme cases, partial or complete roof collapse.
3. Ventilation and Drainage Blockages
Heavy snow can obstruct essential rooftop components, including:
- Roof drains, leading to improper water runoff and ice dam formation.
- Ventilation systems, reducing airflow and increasing indoor humidity.
- HVAC equipment, which may become buried under snow, causing operational issues.
Why You Should Hire a Certified Roofing Professional for Snow Removal
While removing snow from a flat roof may seem straightforward, it requires expertise to prevent unintentional damage. Certified roofers:
- Have Working at Heights training to ensure safe removal procedures.
- Understand how to avoid damaging the roofing membrane and ventilation systems.
- Use the right tools and techniques to prevent tearing, punctures, or seal breakage.
- Assess the roof’s condition before and after removal, ensuring structural integrity.
Best Practices for Protecting Your Flat Roof in Winter
1. Monitor Snow Accumulation
- Keep an eye on snowfall levels, especially after major storms.
- If accumulation exceeds 12 inches, consider professional snow removal.
- Wind can create drifts, causing higher levels of snow in hard to see areas.
2. Schedule Regular Inspections
- Pre-winter inspections help identify potential vulnerabilities.
- Mid-season check-ups ensure drains and ventilation remain clear.
- Clearing snow regularly can prevent leakage due to ice build up.
3. Ensure Proper Drainage
- Clear leaves and debris from drains before winter begins.
- Remove ice buildup that could obstruct water flow.
- Avoid salt or sand as melting agents to help reduce clogging
4. Use Professional Snow Removal Services
- Avoid DIY removal, as improper techniques can damage roofing materials.
- Certified roofers know how to safely clear snow without harming the structure.
- Avoid liability issues with trained roofing professionals.
