Snow on your roof, hanging over the eaves. Isn’t that a beautiful sight? It’s almost like something out of a Currier and Ives print. So take a photo, but then immediately knock it down. For as picturesque as it can be, snow on your roof can also be damaging to your Fairfield County home when it turns into ice dams.
There is more than one type of ice dam. For instance, one can occur when chunks of ice clump together to block the flow of a river. But a different kind of ice dam can form on your roof, causing water damage to your home if not taken care of quickly.
What is an Ice Dam?
Ice dams form when snow on your roof melts and then refreezes at the edges of the roof. This builds up a ridge of ice that prevents melting snow from draining off the roof. This happens when warm air that escapes from your house warms the surface of the roof and melts the lowest layer of snow on top of it. That melted snow flows down your roof until it reaches the colder eaves where it refreezes. When this happens over and over, a dam-like structure is created that traps water on the roof.
Water Damage Caused by Ice Dams
When water is trapped on your roof, it can make its way into the roofing material, shingles, and even the interior of the house, causing extensive damage. The consequences of ice dams may include:
- Roof Damage: The continuous freezing and thawing process can jeopardize the stability of your roof, leading to leaks. In severe cases, structural damage can occur.
- Interior Water Damage: Water seeping into your attic or walls may harm or even destroy insulation, ceilings, and drywall. It could also encourage mold and mildew growth, posing health risks.
- Gutter and Downspout Damage: The weight of ice dams can impair or even tear down gutters and downspouts. A gallon of ice weighs about 7.59 pounds, so it wouldn’t take much to mangle them.
- Icicle Formation: As ice dams grow, they often create large icicles. These can pose a safety hazard for family members and pets.
Preventing Ice Dams
Keeping ice dams from forming on your Fairfield County home requires a combination of insulation, ventilation, and proactive measures. Here are some things to check for and effective actions you can take:
- Proper and Sufficient Insulation: Make sure your attic is adequately insulated to decrease heat transfer to your roof. This helps maintain a consistent roof temperature and reduces the likelihood of snow melting and refreezing.
- Ventilation: Circulating air is crucial for maintaining a uniform roof temperature. Ridge and soffit vents help create a continuous flow of air and prevent heat buildup in your attic.
- Sealing Gaps: Find and seal any gaps, cracks, or openings in your attic as they can allow warm air to escape. This includes all areas around chimneys, vents, and light fixtures.
- Snow Removal: Safely clear snow off your roof using a roof rake. You may want to hire someone to have this done. Removing the snow before it can melt can prevent the formation of ice dams.
- Gutter Maintenance: Make sure your gutters and downspouts are flowing freely. This will help prevent water from pooling behind ice dams.
- Eave Protection:Install heat cables or eave protection systems along the roof’s edges. This decreases the possibility of ice dam formation.
- Professional Inspection: Schedule regular inspections by roofing professionals. They can identify and focus on potential issues before they get worse.
