Incredibly common in Massachusetts, ice dams are a buildup of ice that forms along the edge of your roof and can prevent water and melting snow from draining away from your roof. Heat loss from the top portion of the roof causes the snow to melt.
As the snow melts, it travels down the lower portion of your roof, hitting cooler air, causing it to freeze again, forming a layer of ice. As the ice forms, it can back up along your roof and shingles- expanding and contracting- creating damage and leaks in your roof, walls, insulation and ceiling.
At LaBelle Roofing, we have spent years helping our customers address the ice dams and subsequent roof leaks. Here are some more helpful hints and myths regarding ice dams. Let us know if you have any questions about ice dams and how they are affecting your home and roofing system- we would love to help!

Prevent Ice Dams with these Helpful Hints
Equalize the attic temperature with the outside air temperature as much as possible:
- Seal attic entry points
- Make sure bath and kitchen vents are properly exhausted through the roof
- Add vents to soffits for passive air flow
- Insulate the attic floor; the us dept. of energy recommends R38-R60
- Closed cell foam insulation systems are expensive but effective in preventing heat transfer and melting
Install active ventilation systems, passive systems are not enough:
- Install powerful fans to draw in the cold, outside air — These are roof mounted in the back of your home & require sufficient intake ventilation
Roof protection systems:
- Install the best quality heating cables in strategic areas to create channels so trapped water can get out; have a qualified electrician connect the wires to your home’s electrical system and inspect cables annually
- Heated gutters/eave systems abound and vary greatly in price and effectiveness
- Leak barriers, commonly known as ice & water shield, are installed when a new roof is installed. These underlayments, while not fail-proof, go a long way toward preventing leaks. Ice and water shields come in different grades. When considering new roofing estimates, get the best quality underlayments you can afford.
