Winter weather

Winter weather can pose significant risks to commercial roofs, leading to potential damage that can be costly and disruptive. Here are some ways winter weather can impact commercial roofs:

Snow accumulation: Snow can accumulate on a roof, creating excessive weight that surpasses the roof’s load-bearing capacity. This added stress can lead to structural damage, including sagging or even collapse.

Ice dams: Ice dams form when snow melts on the warmer upper areas of the roof and refreezes near the colder roof edges. These ice formations block proper drainage, causing water to back up under shingles or other roofing materials. As the trapped water expands when it freezes, it can cause roof components to lift, crack, or separate, resulting in leaks.

Freezing and thawing cycles: Fluctuating temperatures during winter can cause the freeze-thaw cycle. When water penetrates cracks or gaps in the roof, it expands as it freezes and contracts as it thaws. These constant expansions and contractions weaken the roof’s integrity, leading to cracks, fractures, or deterioration of roofing materials.

Condensation: Cold temperatures outside and warm air inside the building can create condensation on the underside of the roof. This moisture buildup can cause mold growth, rotting of structural components, and damage to insulation or other materials.

Wind damage: Winter storms often bring strong winds that can lift or dislodge roofing materials. Once the roof’s protective layer is compromised, water can infiltrate, leading to leaks and further damage.

To mitigate these risks, commercial building owners should consider:

Regular inspections: Conduct routine roof inspections before and after winter to identify any pre-existing issues and address them promptly. This can help prevent small problems from escalating into major damage.

Snow removal: Engage professional snow removal services to clear excess snow from the roof, reducing the risk of overloading and potential structural damage.

Insulation and ventilation: Ensure adequate insulation and proper ventilation within the building to minimize condensation and ice dam formation.

Roof maintenance: Schedule regular roof maintenance, including sealing cracks, replacing damaged shingles or membranes, and clearing debris from gutters and drains to maintain optimal roof performance.
