Snow Removal on Commercial Roofs

Winter in Detroit can be beautiful, but for commercial property owners and facility managers, it also brings serious roofing concerns. Heavy snowfall, ice accumulation, and freeze-thaw cycles can place tremendous stress on commercial roofing systems. Without proper snow removal practices, buildings can experience structural strain, leaks, drainage problems, and dangerous safety hazards.  At Motor City Roofers, we help Detroit-area businesses protect their buildings during harsh Michigan winters with professional commercial roof snow removal and preventative maintenance services. Understanding when and how to remove snow from your roof can help you avoid costly damage and keep your facility operating safely all season long.

Why Snow Accumulation Is Dangerous for Commercial Roofs
Commercial roofs are engineered to support a certain amount of weight, but excessive snow loads can exceed those limits—especially during severe storms or long winters with repeated snowfall. Wet, compacted snow is particularly heavy. In some cases, just one foot of wet snow can weigh more than 20 pounds per cubic foot.
When large amounts of snow build up, the risks include:

• Structural stress and roof deck deflection
• Roof leaks and membrane damage
• Ice dams and blocked drainage systems
• Collapsed rooftop equipment supports
• Increased slip-and-fall hazards around entrances and walkways
• Interior water damage and operational disruptions

Older buildings, flat roofs, and facilities with poor drainage are especially vulnerable. Detroit’s freeze-thaw conditions also create additional stress as melting snow refreezes overnight.

Flat Commercial Roofs Require Special Attention
Unlike steep residential roofs that naturally shed snow, many commercial buildings feature low-slope or flat roofing systems. These roofs tend to hold snow for longer periods, increasing the weight burden and moisture exposure.  Flat roofs commonly used on warehouses, manufacturing plants, retail centers, and office buildings require careful monitoring during winter storms. Snow can drift unevenly across the roof due to wind patterns, creating concentrated pressure points that strain the structure.
At Motor City Roofers, we regularly inspect flat commercial roofs throughout the winter season to identify dangerous snow accumulation before it becomes a serious issue.

Warning Signs Your Commercial Roof Needs Snow Removal
Business owners and facility managers should never ignore signs of excessive snow load. Some indicators that immediate snow removal may be necessary include:

Sagging or Deflection
Visible dips in ceiling tiles, beams, or rooflines may indicate excessive weight on the roof structure.

Interior Leaks
Melting snow and ice can penetrate seams, flashing, or weak areas in the membrane, causing water infiltration inside the building.

Creaking Sounds
Unusual noises from the roof structure may signal stress or movement under heavy snow loads.

Ice Buildup Around Drains
Blocked drains prevent melting snow from escaping, increasing the likelihood of ponding water and ice expansion damage.

Uneven Snow Drifts
Large snow drifts can place concentrated pressure on one section of the roof, creating an imbalance in structural load distribution.  If you notice any of these warning signs, contacting a professional roofing contractor immediately is critical.

The Importance of Professional Snow Removal
Commercial roof snow removal is not a do-it-yourself task. Improper removal techniques can puncture roofing membranes, damage flashing, void warranties, and create dangerous conditions for workers.

Professional crews use specialized tools and techniques designed to protect the roofing system while safely removing excess snow. At Motor City Roofers, our teams are trained to work on all major commercial roofing systems, including:

• EPDM roofing
• TPO roofing
• PVC roofing
• Modified bitumen systems
• Metal roofing
• Roof coating systems

We understand how each material reacts to freezing temperatures and snow removal equipment, allowing us to minimize damage during the process.

Safe Snow Removal Techniques
One of the most important aspects of commercial roof snow removal is protecting the roof membrane. Aggressive scraping or using sharp metal tools can cause punctures and tears that later develop into leaks.
Our snow removal process focuses on:

Using Non-Damaging Equipment
We use plastic shovels, soft-edge pushers, and specialized snow removal tools designed specifically for commercial roofing systems.

Maintaining Protective Snow Layers
In many cases, it’s best to leave a thin layer of snow on the roof to avoid damaging the membrane underneath. Removing every inch of snow is rarely necessary.

Protecting Drainage Systems
Clearing drains, scuppers, gutters, and downspouts is essential to allow melting snow to flow properly away from the building.

Monitoring Ice Conditions
Ice accumulation can create additional hazards and structural stress. We safely address frozen drainage systems and hazardous ice buildup without damaging the roof.

Preventative Roof Maintenance Before Winter
The best snow removal strategy begins long before the first snowfall. Preventative maintenance helps reduce winter roofing emergencies and extends the life of your roofing system.
Motor City Roofers recommends scheduling fall inspections to identify vulnerabilities before winter weather arrives. Key maintenance items include:

• Cleaning drains and gutters
• Repairing flashing and seams
• Inspecting rooftop HVAC curbs and penetrations
• Checking insulation for trapped moisture
• Ensuring proper drainage slope
• Evaluating structural load capacity

A well-maintained roof handles snow and ice much more effectively than one with existing damage or drainage problems.

Ice Dams and Freeze-Thaw Damage
Although ice dams are more common on residential roofs, commercial buildings can also experience ice-related problems. Freeze-thaw cycles allow melted snow to seep into small openings before refreezing and expanding. Over time, this can split seams, crack flashing, and damage roofing materials.  Flat commercial roofs are especially vulnerable when drainage systems become blocked by ice. Water trapped beneath snow layers can infiltrate the membrane and insulation, leading to hidden moisture damage.
Professional winter inspections help identify these issues early before they become major repair expenses.

Emergency Snow Removal Services
Michigan winters can be unpredictable. Severe snowstorms sometimes require immediate action to protect a building’s structural integrity and keep operations running safely.
