As the weather cools down and the snow begins to fall, it’s important to be aware of the potential problems with your commercial roofing. Winter weather can cause various issues, from ice dams to leaks, so it’s important to be prepared. Here are some of the most common problems with commercial roofing in the wintertime.

Ice Dams

Ice dams can form when the snow melts and then refreezes, creating a dam that prevents future melting snow from draining properly.  This can cause damage to the roof, gutters, and walls of the building. Ice dams can also cause water to back into the building, leading to flooding. 

You can prevent ice dams from forming by keeping your gutters clean and clear of debris and ensuring that your roof is properly insulated.

Snow and Ice Buildup

While a small amount of snow and ice accumulation is normal, too much can lead to serious problems for your roof. One of the biggest dangers of excess snow and ice on your roof is the potential for a collapse. The weight of the snow and ice can stress your roofing system, which could eventually cause it to give way.

If you’re concerned about excess snow and ice buildup on your commercial roof this winter, there are some steps you can take to prevent it. First, make sure that your gutters and downspouts are clear of debris. This will allow melting snow and ice to flow freely off your roof. Secondly, you can install a roof rake. This tool safely removes snow and ice from your roof without damaging the shingles. Finally, consider having heated cables installed on your roof. These cables help prevent ice dams from forming, which can cause serious damage to your roof.


The cold weather can cause the roof to expand and contract, creating gaps and cracks. These gaps and cracks can allow water to seep into the building, causing damage to the structure and contents.

How can you prevent leaks in your commercial roof? First, ensure that your gutters and downspouts are clear of debris so they can properly drain water away from the building. Second, inspect your roof regularly for any signs of damage or leaks. If you see any problems, contact a professional roofer to have them repaired as soon as possible. Lastly, consider having a professional roofer install a waterproofing membrane on your roof to help prevent leaks in the future.

Damage From Freezing and Thawing

This type of damage is caused by water seeping into cracks in the roof. The water freezes and expands when the temperature drops, widening the cracks.  As the weather warms up and the ice melts, the water seeps further into the cracks, causing even more damage. Over time, this can lead to leaks, rot, and other serious problems. 

To avoid this type of damage, it’s crucial to have a strong, well-maintained roof. Regular inspections and repairs can help identify potential problems before they cause major damage.

Reduced Insulation

Commercial roofs are typically made of materials designed to withstand the elements, but these materials can degrade and lose their effectiveness over time. This is especially true in the case of wind and snow damage, which can cause the material to become less durable and more susceptible to leaks.

One way to prevent reduced insulation from becoming a problem is to inspect your commercial roof by a professional regularly. They will be able to identify any areas at risk and make repairs as necessary. Doing this can help keep your commercial roof in good condition and avoid any potential issues arising from reduced insulation.


It is important to be aware of the common problems with commercial roofing in the wintertime. You can avoid many of these issues by taking the necessary precautions and being proactive. If you have any concerns, be sure to consult with a professional roofing contractor.
