Ice dams are one of the potential dangers that your Shoreline roof faces in the winter and they can cause significant damage to your shingles, but the good news is that they are not inevitable. There are steps you can take to minimize the damage to your roofing even in cold weather.
Before you see ice dams forming, it’s a good idea to make sure your gutters are clean and that the water that runs off the roof will have a place to go with downspouts that are clear. If it’s already snowy or icy outside and you forgot to clean the gutters this year, you will need to be extra vigilant about watching for ice dams.
Ice dams form when warm air from your house escapes through the attic, melting the snow and ice from the top of your roof. When that melted water reaches the edges of the roof where it’s cold, it can freeze and create the dam. To reduce or eliminate ice dams entirely, check your attic insulation and add more if necessary. This will help maintain a more constant (colder) temperature in the attic so that snow on the top of the roof won’t melt.
Another option to keep warm air from reaching the top of the attic and melting water on the roof is to check your roofing ventilation. Having proper ventilation can keep cooler air from outside circulating through the attic, minimizing the effects of the warm air that does make it through your ceilings. There are specific measurements for installing ventilation based on your home’s square footage, so talk to a roofing contractor in Shoreline to make sure you get the calculations right before installing or remove any vents.
Making some small changes to your home to help reduce the chance of ice dams can help prevent shingle damage from standing water that freezes on the edges of your Shoreline roofing. To find out more or get help with ice dams, call a Shoreline roofer today.
