Heavy Snow and Commercial Roofing in Wisconsin: A Comprehensive Guide to Risk Management


The impact of heavy snow loads on commercial roofs is a topic of paramount importance in Wisconsin, where the winters are not only long but also harsh. As the owner of Dynamic Alliance Roofing, I have observed and dealt with the challenges that snow accumulation poses to commercial structures. The risks associated with heavy snow loads are multifaceted, affecting not only the structural integrity of buildings but also the safety of the occupants.

The primary concern is the weight of the snow. It’s a common misconception that all snow is equal; however, the reality is far from it. Wet snow is significantly heavier than dry, fluffy snow. This difference in weight can be crucial in determining the risk posed to a roof. In Wisconsin, where the weather is unpredictable, even a short period of heavy snowfall can lead to a substantial accumulation, exerting immense pressure on commercial roofs.

The design and age of a building play a crucial role in its ability to withstand heavy snow loads. Newer buildings are typically designed with the regional climate in mind, often incorporating features that help mitigate the risks associated with heavy snowfall. However, older structures may not meet these current standards, making them particularly vulnerable during the winter months. The type of roofing material also factors into a building’s resilience. For instance, materials like metal roofing might fare better under heavy snow loads compared to other materials.

Regular roof inspections are essential, especially before the onset of winter. These inspections help identify potential vulnerabilities, such as areas of wear or damage that could compromise the roof’s ability to handle additional weight. Moreover, they provide an opportunity to assess the roof’s drainage system, ensuring it is clear and functioning correctly to handle melting snow and ice.

Professional snow removal is another crucial aspect of managing the risks associated with heavy snow loads. This task requires a nuanced understanding of how snow can be safely and effectively removed from different types of roofing materials and designs. Improper snow removal techniques can cause damage to the roof, exacerbating existing issues or creating new ones. It’s important that this task is carried out by professionals who understand the intricacies involved.

Emergency preparedness is an often overlooked but vital component of managing the risks associated with heavy snow loads. Having a response plan in place for scenarios like a roof collapse is crucial. Such a plan should include steps for safely evacuating the building, contact information for emergency services and roofing professionals, and measures to protect the assets inside the building.

The financial implications of neglecting these measures can be significant. Beyond the immediate threat to the safety of occupants and the physical integrity of the building, there are long-term financial repercussions. Regular maintenance and professional snow removal are not just cost-saving measures in the long run but also crucial aspects of responsible property management.

Insurance coverage is another important consideration. Building owners should be aware of what their insurance covers regarding snow damage and ensure that they are compliant with any requirements for maintenance and inspections. This not only protects the investment but can also be a lifesaver in the event of damage or a collapse.

Staying informed about the latest building codes and standards is essential. These regulations are designed to ensure safety and are particularly pertinent in areas like Wisconsin, where the weather poses unique challenges. Ensuring that your building complies with these standards is not just a matter of legal compliance but a vital aspect of risk management.

Finally, there’s the human aspect to consider. Ensuring the safety of those who use the building is a responsibility that cannot be taken lightly. It’s about creating a safe environment for employees, customers, and any other visitors to your commercial property.

In conclusion, managing the impact of heavy snow loads on commercial roofs in Wisconsin requires a comprehensive approach. Regular inspections, professional snow removal, emergency preparedness, understanding insurance policies, and compliance with building codes are all essential components of this approach. The safety of our buildings and the people who use them depends on it. As roofing professionals, it’s our job to ensure that commercial property owners are aware of these risks and take proactive steps to mitigate them.
