Winter can be unforgiving for commercial roofs, particularly in regions with harsh weather like the Midwest. Ice, snow, and freezing temperatures put significant stress on roofing systems, leading to costly repairs if not addressed proactively. In this blog, we’ll explore winter roofing challenges and how business owners can effectively manage them.
Major Risks to Commercial Roofs in Winter
Winter months expose commercial roofs to various hazards that can affect their longevity and structural integrity. Addressing these problems early can prevent expensive repairs and downtime.
1. Heavy Snow and Structural Stress
Heavy snow accumulation is a serious threat to commercial roofs, especially flat or low-slope systems. As snow builds up, the additional weight can cause structural stress, leading to sagging or even roof collapse.
How to Handle It: Schedule regular snow removal services during winter storms. Consider installing a snow-melting system or reinforced roofing materials to manage heavy snow loads efficiently.
2. Ice Dams and Water Damage
Ice dams occur when heat from inside the building melts rooftop snow, which then refreezes at the edges. This ice buildup blocks proper water drainage, forcing water under the roofing membrane.
How to Handle It: Ensure proper attic insulation and roof ventilation. These measures balance roof temperatures and reduce the risk of ice dams forming.
3. Temperature Swings and Material Damage
Fluctuating winter temperatures cause repeated freezing and thawing, which can damage roofing materials. Water that seeps into small cracks expands when it freezes, widening the gaps and causing serious leaks.
How to Handle It: Choose flexible roofing materials like TPO or PVC membranes that resist cracking and splitting. Schedule regular inspections to identify and repair early signs of damage.
4. Blocked Roof Drainage Systems
Blocked roof drains, scuppers, and downspouts are common winter issues. Ice, debris, and snow can clog drainage systems, leading to ponding water that weakens the roof structure.
How to Handle It: Clean gutters and drains before winter arrives. Install heating cables around critical drainage areas to prevent ice buildup.
5. Membrane Shrinkage and Leaks
Some roofing membranes contract in extremely cold weather, leading to tears, cracks, and open seams. If left unchecked, these issues cause water infiltration and roof damage.
How to Handle It: Use cold-weather-resistant roofing membranes and maintain a routine inspection schedule. Promptly repair any cracks or damaged seams to prevent water penetration.
Best Practices for Winter
Preventative maintenance is the best defense against winter roof damage. A few proactive measures can significantly reduce the likelihood of costly repairs.
1. Schedule a Pre-Winter Roof Inspection
Hire a professional roofing contractor to inspect your roof for damage, wear, or weak points before winter hits. Fixing minor issues early prevents expensive emergency repairs.
2. Create a Snow and Ice Management Plan
Establish a snow and ice removal plan with a trusted roofing company. Regular snow removal prevents overloading and reduces structural stress.
3. Improve Roof Insulation and Ventilation
A well-insulated and ventilated roof minimizes temperature differences, preventing ice dams and maintaining energy efficiency.
4. Partner with Emergency Roofing Services
Partner with a reliable commercial roofing contractor like Sterling Roof Systems for emergency repair services. This preparation ensures quick responses when winter weather causes unexpected damage.
