Modern commercial roofing materials are extremely durable, offering decades of protection from sun damage, rain, and a wide range of other threats. However, winter weather brings additional concerns, many of which can cause severe damage and the need for premature roof replacements. Below are some of the ways colder conditions can damage your roof, even in relatively mild climates.

3 Winter Hazards for Commercial Roofs

1. Strong Winds

Most commercial and industrial buildings feature flat roofs, which are less prone to wind damage than pitched rooflines. However, if your roofing membrane is getting old or the last roof replacement wasn’t completed correctly, wind from winter storms can loosen flashings or result in a total blow-off. While some damage will be immediately apparent, some issues can go undetected for months until water starts penetrating the inside of your building.

2. Heavy Snow

One disadvantage of flat roofs is steady snow accumulation across the entire structure, which can lead to serious structural issues. On extensive roofs, a few inches of snow accumulation can add thousands of pounds to the roof structure, condensing insulation, and warping support beams. Brushing off snow and ice as soon as it accumulates can help prevent damage and reduce the weight on your roof.

3. Thermal Shock

Towards the end of winter, it’s not uncommon to have relatively warm days followed by below-freezing temperatures at night. These rapid temperature changes cause the roof membrane to expand and contract, cracking joints and tearing apart seams on older roofs. Newer materials are less susceptible to damage caused by shifting temperatures, so be sure to schedule a roof replacement before you notice any issues or the weather becomes too cold.
