Nobody likes them and they’re not a lot of fun, but they keep coming and coming.
They are Ice Dams and, fortunately, they are preventable.
Ice dams are caused by the build up of ice and snow on your roof.
Melting and re-freezing contributes to more snow and ice building up.
Watch for ice dams near gutter downspouts.
Keep gutters free of leaves and debris so melting snow and ice can flow freely.
Ice dams can cause water to build up and seep into your house destroying walls, floors and personal property.
