As temperatures change, water freezes, then melts, and refreezes against. Often, as water moves down a surface, you see icicles form. While icicles might be beautiful to look at, when they are hanging from your roof or gutters, they can cause devastation inside your home. What you see might be the start of an ice dam, which can be the root cause of a water damage.
How does it happen? After all, don’t most water damages occur from broken pipes or sudden heavy rain? Not always.
How ice dams form
In the winter, where temperatures drop below freezing, snow melts and then the water runs down the roof and then hits the cold roof eaves and gutters and freezes into ice dams. These tear off gutters, loosen shingles, and cause melting water to work its way under the shingles, and into your home—instead of off the roof like it normally should.
This can damage interior walls, insulation, woodwork, ceilings… it can warp your floors and even lead to mold forming inside your home, where it does not belong. But all of this can be prevented with a little planning.
Preventing ice dams
In the short term, you can put some ice melt products (calcium chloride), much like you would put on the sidewalk, on areas where ice may build up. You can sprinkle these liberally on the eaves and in the gutters. Some recommend putting the ice melt products in socks or pantyhose and laying them up on the roof, so it crosses over the eaves and gutter. No matter what you do, think safety first and be very careful on ladders or when accessing anything high.
In the long term, insulating your attic should be a priority. Have it inspected to ensure you have the right type and amount of insulation materials. If you can keep the entire roof the same temperature as the eaves, you stop the formation of ice dams. You do this by increasing ventilation in the attic and plugging every possible air leak that might warm the roof, which melts the snow. We all know everything must melt, but premature melting is the issue here.
But when and if water damage happens, you need help before things go from bad to worse. Do the right thing and call your favorite disaster restoration company. After all, it pays to call a pro!
