When a snowstorm hits, you are probably worried that the power will go out in your Concord, MO, building. You may also fear that a burst pipe will flood your office. Yet winter weather can also affect your commercial property in another way. An ice dam can form on your roof, leading to the growth of black mold.

Ice Dams and Mold

Ice dams occur when snow melts on top of a warm roof. The melted water then flows to the colder eaves, where it refreezes into ice. This ice blocks additional water from dripping off the edge of the roof. The water instead goes under the shingles and into the building, where it can damage:

  • Insulation
  • Sheetrock
  • Wall studs

When these parts of the building get wet, they create a breeding ground for mildew and mold. By the time you notice the fungus, you may not be able to handle the problem on your own. Instead, you may need to contact mold remediation specialists, which could affect your company's profits. You may even have to close down the property temporarily while the ice dam is removed and mold cleanup is performed.

Stopping Ice Dams

There are simple steps you can take to limit the development of ice dams. Try adding insulation or heated cables to ensure the entire roof remains fairly warm. You should also put caulk around any pipes or vents and seal exhaust and HVAC ducts.

Fixing Ice Dams

If you do see one or more ice dams, you should get rid of them immediately before they cause mold damage. You can quickly and safely break up the dam with a roof rake.
An ice dam could cause water to back up on your roof and leak into your building. This, in turn, could necessitate extensive black mold cleanup. To prevent this occurrence, maintain a consistent temperature on the roof and quickly address any dams that form.
