Ice Dam Prevention

While we haven’t had much snow this season, winter is still in full swing and this week’s freezing temperatures were a stark reminder that the worst is likely yet to come. It won’t be long before another storm rolls through to remind us why proper home maintenance is so critical this time of year. 

One common winter issue homeowners face is ice dams—and they can wreak havoc on your home if you’re not prepared. An ice dam forms when snow blankets your roof, creating an extra, unwanted layer of insulation. As warm air rises from your home into the attic, it melts the snow on your roof. The water then slides down to the eaves and gutters, where the colder surface temperatures cause it to refreeze. Over time, this process creates a growing mass of ice at the edge of the roof, commonly known as an ice dam.

These icy buildups are more than a minor inconvenience—they can cause significant damage. Heavy ice can tear gutters away from your home or even lift roof shingles, leaving gaps for water to seep into your attic. From there, leaks can spread to ceilings and walls, creating a costly mess.

The key to preventing ice dams is ensuring your home is properly insulated and ventilated. Unfortunately, many homes in our area lack adequate insulation. In fact, more than 75% of New England homes are under-insulated, allowing heat to escape straight through the roof. This problem is often a result of outdated building standards—homes built decades ago weren’t designed to handle the harsh winters of Connecticut.

By upgrading your home’s insulation and ventilation, you’ll do more than just protect your roof. A well-insulated home is more comfortable year-round, keeping you warmer in the winter and cooler in the summer. You’ll notice the difference immediately and see the impact on your energy bills too. Proper ventilation also helps reduce the risk of mold and mildew buildup, which can harm both your home and your health.

Investing in these upgrades is a simple yet powerful way to protect your family, your house, and your budget. Don’t wait for the next big storm to highlight what’s missing—take steps now to keep your home safe and comfortable all year long.

Watch for Ice Dams

With a week of snow, ice, and temperatures all over the place, it’s a great time to remind homeowners about ice dams. 

Ice dams occur when the heat from the inside of a house melts the snow on the roof, causing water to run down and refreeze at the edge of the roof. Over time, this can create a thick layer of ice that can cause damage to the roof and even leak into the house.

The first sign of an ice dam is often the formation of icicles on the edge of the roof. While icicles may look pretty, they are a warning sign that water is not draining properly and may be backing up under the roof shingles. Other signs of an ice dam include water stains on the ceiling or walls, peeling paint or wallpaper, and damp insulation.

Preventing ice dams is much easier than dealing with them after they form. Here are some steps you can take to make sure your home isn’t susceptible to the problem:

1. Keep your gutters clean. Gutters filled with debris can cause water to overflow and freeze on the edge of the roof, leading to ice dam formation.

2. Insulate your attic. A well-insulated attic will keep the heat inside your house from melting the snow on the roof.

3. Ventilate your attic. Proper ventilation will help prevent heat buildup in the attic, which can contribute to ice dam formation.

4. Consider installing an ice and water shield. This is a type of roofing material that is designed to prevent water from seeping into the house if an ice dam forms.

If you already have an ice dam, there are a few things you can do to remove it:

1. Use a roof rake to remove snow from the edge of the roof. This can prevent more water from backing up and freezing.

2. Fill a pair of pantyhose with calcium chloride ice melt and lay it across the ice dam. This can help melt the ice and create a channel for water to escape.

3. Hire a professional. Removing an ice dam can be dangerous, especially if you have to climb on a ladder or walk on a slippery roof. It's best to leave this job to the professionals.

Ice dams are both a common and serious issue that can cause damage to your roof and home. Taking steps to prevent ice dams from forming is the best way to avoid this problem. If you do have an ice dam, there are ways to remove it, but it's important to be cautious and seek professional help if necessary.

Beware of Dangerous Ice Dams

We all know that snowfall, freezing rain, and sleet make for icy conditions on sidewalks and roads. But did you know that your roof is actually where hazardous winter weather can do the most harm? 

I’m talking about ice dams, a solid mass that forms when heavy snow blankets the roof, creating an extra layer of insulation. As warm air rises from your house and up through your attic, it causes the snow to melt and the water to slide down into the gutters. This would normally be just fine, but because so many homes in our area aren’t properly insulated, the melting ice will often make contact with the cold eaves of the roof and freeze again instead of draining off through the gutters. This forms an ice blockage. 

If not taken care of, that ice can grow if the weather stays cold. The dam can even get strong enough to lift up your roof shingles, creating gaps that will let the water through and into the attic. This is when people start to see leaks in their ceilings and walls. 

The best way to avoid this problem is by taking preventative measures. When you’re shoveling your driveway and clearing your sidewalks, think about snow removal for your roof too. This will help to avoid any potentially dangerous build-up. If an ice dam is already forming, one easy way to get rid of it is to simply fill a pair of pantyhose with ice melt and put it directly on the dam. If you’re not used to being on a ladder, don’t even think about getting up there in the winter months. A professional can help clear any winter debris from the house safely.

These, of course, are just stop-gap measures. The only way to prevent ice dams from forming permanently is to have your home properly insulated and ventilated. More than 75% of homes in our area are under-insulated which causes the heat from your home to shoot right through the roof. Having appropriate insulation and ventilation will keep your home free from ice dams and will keep you much more comfortable in both the winter and the summer. You’ll feel the difference immediately, and you’ll see the benefit in your energy bills too.
