The Damaging Impacts of Snow and Ice on Your Roof

Winter is just around the corner. Most people tend to take for granted the work of roofing systems during these cold months. While you will stay safe from snow and wind storms, the roof bears the brunt of the harsh weather.

Snow and ice can have devastating effects on your commercial roof. Most homeowners neglect roofing service prior to the wintry months. Winter damage is not limited to typically colder climates. Warm regions with unusual winter weather patterns are also vulnerable to snow and ice hazards.

The Effects of Snow and Ice on the Roof

Winter icy temperatures bring to mind images of snow-covered roofs with dangling icicles. While it may be beautiful scenery for your home, the reality is that the snow, rain, and wind storms can be hard on your roof. Here is a list of common issues and some winter roofing service tips.

1. Ice Dams

The last thing you would wish for this winter is to have a bucket brigade. The freeze and thaw cycles on your roof can wreak havoc on your roof. The warm temperature under the attic melts the snow on the roof surface, which refreezes, causing ice dams on the roofing. The repeated cycles can cause cracks on your shingles, leading to water leaks.

You may need to ensure your attic is well-ventilated to allow warm air from inside to escape without heating the roof. It also ensures that you keep the heat within the house.

2. Excessive Snow Load

The weight of snow may place tremendous strain on a roof, leading to damage. One cubic foot of snow typically weighs approximately 20 pounds. When it melts to ice, the load may increase up to 60 pounds. The snow load can bear down on the decks, causing damage to other load-bearing structures. It can also force water underneath, causing leaks.

As part of your winter roofing service, ensure that your remove snow as soon as possible. Conduct a thorough inspection with a professional roofing company to identify potential issues that may occur. Throughout winter, look for signs of damage that can indicate excessive snowfall.

3. Thermal Shock

Your roof may also suffer from repeated temperature extremes. The daytime high temperatures will warm the roofing, thawing the surface. Nightfall comes with frigid temperatures that drop to sub-zero levels. Over time, it may lead to deterioration and roof weakening. The condensation in the attic due to the thermal effects may also lead to mold growth and wood rot.

Snow removal can help you eliminate the excess weight that may bear down during the repeated warming and freezing. Regular inspections by qualified roofers can help you make the necessary roofing service repairs before the snowfalls. The roofing company can also calculate your cold-weather risks and formulate a plan to mitigate them.

Snow and ice build-up can cause considerable damage to roofing systems. You need to ensure that your roof is inspected once or twice a year. For more information on how you can protect your roof, feel free to contact Roofing Renovations.
