Ice dams occur when ice builds up along the eaves of your roof. They form when snow and ice melt off your roof and re-freeze when they reach the eaves. If the ice dam grows large enough, it can prevent water from draining off the roof. This can back up the water underneath the roof’s shingles and make its way into the home.
There are steps you can take to help prevent damage from ice dams.
• One of the best ways to prevent ice dams from forming is to clear snow and ice off the roof right away. By removing the snow and ice with a roof rake after it snows you can avoid ice dams from forming.
• Another thing you can do is to shovel around downspouts so that your gutters can drain freely. By doing this you can prevent ice buildups in gutters.
• One other thing you can do to avoid ice dam damage to your home is to properly insulate and ventilate your attic. When your attic is cold, it increases the chances of ice dams from forming. Proper insulation and ventilation will reduce the chances of snow melting on your roof and refreezing at the eaves.
By following these steps you can help prevent ice dams from forming on the roof of your home. If you do clear your roof of snow and ice, always do so with caution. Never attempt to climb on top of a snowy or icy roof and never place a ladder on a snow or ice covered ground.
