Why Ice Damming Is a Serious Problem for Commercial Roofs:
Ice damming on commercial roofs is more than a nuisance—it can lead to severe structural and financial consequences, especially during Ontario’s harsh winters. Commercial properties, particularly those in Hamilton, Oakville, Burlington, Niagara, and Mississauga, face unique challenges, such as:
- Flat Roof Vulnerability:
- Flat or low-slope roofs typical of commercial properties drain water slowly. If water freezes overnight, it can lead to blockages that worsen over time.
- Larger Surface Area:
- Commercial roofs accumulate more snow than residential roofs, increasing the risk of ice dam formation.
- Greater Risk of Interior Damage:
- Water penetration from ice dams can damage ceilings, HVAC systems, electrical wiring, and valuable inventory.
The Cost of Ignoring Ice Dams on Commercial Properties
Case Study: A Burlington Office Complex
A local office complex in Burlington experienced significant downtime when an ice dam caused water to leak into their IT room. Not only did they face $30,000 in repairs, but they also lost several days of business operations, resulting in even more financial losses.
Ignoring ice damming risks could lead to:
- Expensive repairs (average costs can exceed $10,000).
- Increased insurance premiums.
- Damage to tenant relationships in multi-use buildings.
How to Prevent Ice Damming on Commercial Roofs?
- Upgrade Roof Insulation:
- Install high-quality insulation to maintain consistent roof temperatures and reduce heat escape.
- Install Heat Trace Cables:
- Heat cables can melt ice in gutters and along roof edges, ensuring water flows freely.
- Maintain Gutters and Drains:
- Clean gutters and roof drains regularly to remove leaves, debris, and ice buildup.
- Inspect and repair gutter seams and fasteners before the winter season.
- Invest in a Membrane Roofing System:
- EPDM, TPO, or PVC roofing membranes can provide better water resistance and prevent ice damming.
- Regular Roof Inspections:
- Schedule biannual inspections (before and after winter) to identify and address potential vulnerabilities.

FAQs About Ice Damming on Commercial Roofs
Q: How much snow accumulation is too much for a commercial roof?
A: Flat roofs are typically designed to handle about 20-30 pounds per square foot. Wet snow and ice are much heavier, so even a few inches can become dangerous.
Q: Can regular snow removal prevent ice dams?
A: Yes, but it’s critical to remove snow carefully to avoid damaging roofing materials. Professional snow removal services are highly recommended for commercial roofs.
Q: How long does it take to repair damage caused by ice damming?
A: Repairs can take anywhere from a few days to several weeks, depending on the extent of the damage. Proactive prevention is much more cost-effective.
Q: Do heat cables work on flat roofs?
A: Yes, heat cables can be installed around drains and roof edges to prevent ice buildup.
