Protect Your Home From Ice Dams
Heat loss through your roof can result in thousands of dollars in damage as a result of ‘ice damming’. Ice damming happens when warm air leaks from your house into the attic, melting the snow on your roof. This water runs down and freezes again at the roof’s edge. This process repeats itself and eventually creates a dam made of ice that prevents water from draining away. Inevitably, this water backs up under the shingles and into your home.
The key to preventing ice dams is to make sure your attic is properly insulated. Experts recommend having a minimum of 8 inches of R20 insulation on your attic floor. However, insulation alone may not be enough. Heat escaping from ceiling fixtures, attic access hatches, exhaust fan systems, chimneys or other perforations in your ceiling can increase the risk of damming.
Here’s what you can do to prevent ice dams or minimize damage:
