How Does Snow Impact My Roof?

Some of us weren't expecting the winter weather we received already which means we may be getting winter sooner than usual. Winter can sometimes lead to problems with your roof especially if you've got an older roof or roof that needs repairing. Have you ever wondered if snow can impact your roof? In today's blog, your Lake of the Ozarks roofers would like to shed light on how snow can impact your roof.

Missouri Snow Trends 

While we don't typically get two feet of snow in one storm like other parts of the country, Missouri does get its fair share of snow. Snow has been known to fall in Missouri as early as October and as late as May; however, most of it falls between December and February. This year, we have already encountered snow which means we may be getting more this winter. Throughout the state, we average anywhere between 8 and 24 inches, with the northern part of the state seeing more snowfall than the south. It is unusual for snow to stay on the ground for more than a week or two, and typically about the same length of time on your roof.

The Impact of Snow on Your Roof

In the event we do get a snowstorm with a good amount of snow, your roof could be in danger. That's why it's so important to take advantage of our free roof inspections at the Lake of the Ozarks every fall. While all roof are originally built to withstand the effects of winter weather, a roof that's already in poor condition could fail. The accumulation of snow and ice on your roof provides added weight. The pressure from this weight could cause your roof to sag or bow. The weight can also transfer horizontal forces causing your walls to deflect or move slightly outward. If the weight of the snow and ice exceeds design capacity, the movement and sagging can become permanent. In extreme cases, the roof could even collapse.

Warning Signs to Look For

Whether or not a roof can withstand the weight of ice and snow is dependent upon the depth and density of the snow, as well as how your roof was built. Here are a few signs that you may have a winter roofing problem:
  • The rafters in your attic are sagging
  • You hear any cracking or popping coming from the attic or roof areas
  • The house's frame has moved enough to jam shut a door or even just make it stick
  • You see the drywall or plaster around door frames start to crack 
  • Severe roof leaks into the attic 
We're hoping for a mild this year, but in the event that we get even more snow, just keep these tips in mind for our next snow! Snow on your roof for an extended period of time is typically not good for your roof but if you ensure your roof is in tip-top shape before winter, you can have peace of mind about your home staying out of the elements.
