Winter can be a tough season for flat commercial roofs. Unlike sloped roofs, flat roofs are more prone to problems caused by heavy snowfall, ice buildup, and poor drainage. For business owners and facility managers, taking a proactive approach to roof maintenance is critical in preventing costly repairs and ensuring the safety of your building.
We want to help you keep your flat commercial roof in excellent condition this winter. Here’s a look at the common challenges heavy snow can bring and actionable tips to protect your roof.
Challenges Flat Roofs Face in Winter
Flat commercial roofs are designed for durability, but winter weather can test their limits. These are some of the main issues they encounter during heavy snowfall:
- Snow Accumulation
Unlike sloped roofs that allow snow to slide off, flat roofs tend to collect and hold snow. The weight of accumulated snow can strain the roof’s structural integrity, leading to sagging or even collapse in extreme cases. - Drainage Problems
Snowmelt needs to drain properly to avoid standing water on the roof. Flat roofs rely on internal drains, scuppers, or gutters to remove water. If these systems are clogged with ice or debris, water can pool on the surface, increasing the risk of leaks and water damage. - Ice Dams
Ice dams occur when warm air from the building causes snow to melt unevenly, refreezing at the edges of the roof. This creates a barrier that traps water, which can then seep into the roofing membrane and cause leaks. - Thermal Stress
The freeze-thaw cycle that’s common during winter can weaken your roof over time. Temperature fluctuations cause roofing materials to expand and contract, which may lead to cracks and damage if not addressed.
Best Practices to Maintain Your Flat Roof in Winter
Taking steps to prepare and maintain your flat commercial roof will help prevent damage and extend its lifespan. Here are some essential tips to keep in mind:
- Conduct Regular Inspections
Schedule routine inspections throughout the winter, even before the first snowfall. A professional roofer can check for pre-existing issues, such as cracks, punctures, or weak spots, that could worsen under snow load. Inspections are especially important after severe snowstorms to assess any new damage. - Monitor Snow Accumulation
Keep an eye on the amount of snow on your roof. On average, most flat roofs are designed to handle about 20 pounds per square foot of snow. Wet or packed snow weighs more than fresh, powdery snow, so regular snow removal may be necessary during periods of heavy snowfall. - Hire Professionals for Snow Removal
Removing snow from a flat roof is risky and should always be left to professionals. Roofing experts use specialized equipment to safely remove snow without damaging the roofing membrane or insulation. Attempting to clear snow yourself could lead to injury or costly roof repairs. - Ensure Proper Drainage
Check that your gutters, scuppers, and roof drains are free of debris and ice. These systems are your first line of defense against standing water, so keeping them clear is vital for preventing leaks and water damage. Heat cables can also be installed around drains and edges to minimize ice buildup. - Inspect Insulation and Ventilation
Improper insulation and ventilation can lead to significant issues, including ice dams. Make sure the building’s attic or ceiling area is well-insulated to prevent heat from escaping and melting snow unevenly. Proper ventilation will also help regulate roof temperature, reducing the likelihood of ice dam formation. - Repair Minor Issues Promptly
Small problems like cracks, blisters, or worn seals might seem minor, but in winter, they can quickly escalate. Addressing these issues early prevents snow and ice from causing further damage, saving you significant repair costs down the line.
Benefits of Proactive Winter Roof Maintenance
Investing time and resources into winter roof maintenance has several benefits, including:
- Avoiding Costly Repairs: Preventative measures are significantly less expensive than fixing major structural damage or leaks caused by neglect.
- Extending Roof Lifespan: Regular care ensures your roof materials remain in good condition, maximizing their longevity.
- Ensuring Safety: Preventing roof collapses or leaks means a safer environment for employees, customers, and visitors.
- Maintaining Business Operations: A functional roof reduces the likelihood of interruptions due to water damage, repair needs, or safety concerns during the winter months.
