2 Tips To Help Keep Ice Dams From Forming On The Edges Of Your Shingled Roof

Posted on: 1 December 2020

Every time a major snowstorm moves into your area, you may notice that large chunks of ice form along the edges of your roof the day after. Known as ice dams, these formations occur when the snow melts during the day and refreezes at night.

Because the sheer weight of the ice can cause damage to the shingles along your roof's edges, you may be wondering what can be done to prevent them. Besides having a roofer install attic vents or take other action, there are a couple of things that you can try.

1.  Remove Fresh Snow Using a Roofing Rake

One thing that you can do to help keep ice dams from forming along the edges of your shingled roof is to remove the fresh snow before it has a chance to melt. To remove the snow, you can purchase a roofing rake from a hardware or home improvement store.

Made from rubber so as not to damage your shingles, the rake helps to gently pull the snow off of the roof. However, if there is ice accumulation, not only will the rake not work, but it will also be more dangerous. 

If your roof already has ice present, has massive amounts of snow, or is on a two-story home, you should either let it be or contact a roofer to see if they can do the job for you.

2.  Keep Your Attic About the Same Temperature as the Outdoors

Another thing you can do while there is snow and/or ice on your roof to help prevent the formation of ice dams is to keep your attic cool. The air temperature should be about the same as the one outdoors.

If the attic's temperature is higher than the outdoor air, it will cause the snow to melt more rapidly. If your attic is not heated but experiences radiant heat from your home, talk to a roofer about having vents installed.

While taking the above action could help to prevent or at least minimize the formation and impact of ice dams on your roof, it may not be enough if you have severe winter storms or your roof is too high off of the ground to remove the snow. If you constantly worry about ice dam formation and the damage it can do to your roof, contact a residential roofing company in your area to discuss what can be done to help prevent them and to assess whether your shingles are already damaged and need replacing.
