What to Know About Ice Dams

This winter has been fairly mild but the season is still in full swing and it won’t be long until we get another storm to remind us that we live in New England. Before that happens, I always like to talk about the dangers of ice dams and the reason why so many homes in our area get damaged by them. 

An ice dam is a solid mass that forms when heavy snow blankets the roof, creating an extra layer of unwanted 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 typically 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 a large ice mass at the gutter line, which will grow if not taken care of.

Solid ice is heavy and can easily pull gutters loose. The dam can even get strong enough to lift up your roof shingles, creating gaps that let the water through and into the attic. This is when people start to see leaks in their ceilings and walls. 

The only way to prevent ice dams from forming 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. Because insulation and ventilation weren’t regulated when most of the homes were built in this area, a lot of us have houses that are better suited for Florida winters than our cold Connecticut climate. 

Having appropriate insulation and ventilation will not only keep your home free from ice dams but will also 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. A house that can breathe and can properly regulate its own temperature will also be less like to accumulate mold and mildew which is not only damaging to your house but also to your health. It’s a simple solution to keep your family, your home, and your wallet healthy.

Get rid of ice dams once and for all

Last week we talked about ice dams, the pesky water build-ups that freeze in your gutters and leave a massive frozen dam that can wreak havoc on your house. As temperatures below freezing become a more regular occurrence for us Connecticutians, it’s a good idea to understand how you can prevent ice dams, and how to safely remove them as a temporary measure.

Ice dams generally form on the outside of homes that aren’t properly insulated and ventilated. The snow and ice on the roof begins to melt, and it slides down the pitch before refreezing into what eventually becomes a nasty layer of ice build-up. Because the water doesn’t have anywhere else to go, it can start to seep into your walls, causing costly leaks inside the home.

So how do you stop this from happening? Firstly, take advantage of a free insulation inspection offered by a local expert. A remodeler can check your attic to see if you have sufficient insulation and ventilation. Over 75 per cent of homes I visit don’t have proper insulation, which will not only allow ice dams to form, it will also let that brutal winter wind come right into your house. Luckily, insulation is an easy and cost-effective solution, which pays for itself in both energy efficiency and resale value. 

A quicker fix is to use heated cables, which you can buy at your local hardware store. By installing these cables on the base of your roof, you will level out the temperature, allowing the snow to melt and the water to drain off the roof and through your gutters like it’s supposed to. Of course, the cables must be installed before the snow hits, when your roof is dry. A 200-foot cable will run you about $150.

These solutions are both very effective, but what if you have an ice dam now? Firstly, be very careful about hacking at the ice with a shovel or pitchfork, as you’ll very likely damage your roof or gutters, and possibly injure yourself in the process. If you have a leak in your attic, start by using a fan to blow cold air at it, which will equalize the temperature and temporarily stop the water from getting in. Then start to pull any excess snow off the exterior of the roof with a shingle safe roof rake. Once the roof is clear of snow, you can use calcium chlorate ice melter to begin tackling the dam. If you have some old, long socks or a pair of pantyhose, you can fill them with ice melter to keep it in place, rather than allowing it to run off the roof with the melting ice.  Keep an eye out for ice melters that are specific to roofs, so you can be sure the chemicals won’t damage your shingles. Do not use rock salt! 

Remember, this is only a temporary fix and won’t prevent future ice dams from forming.  Also, ice dam removal can be dangerous work, so only attempt it if you are very comfortable working on a ladder. If not, contact a professional for help.
