Be Aware of Ice Dams After a Major Winter Storm

With our first official storm in the books, now is a perfect time to talk about how dangerous winter weather can be for your house. We all know that major snowfall, freezing rain, and sleet make for icy conditions on sidewalks and in your driveway, but what about on your roof? Sure, icicles might look pretty, the ice dams creating them can result in major leaks in your attic, ceiling, and interior walls.

An ice dam forms when heavy snow blankets the roof, forming an extra layer of insulation. As warm air rises from your house and up through your attic, it causes the layer of snow closest to the roof to melt and the water to slide down into the gutters. This would normally be a good thing, but because so many homes in our area aren’t properly insulated, what often happens is that the melting water hits the cold eaves of the roof, freezing again instead of draining off through the gutters. This forms an ice blockage. As that ice grows and grows, the water has nowhere to go so it starts to move under your roof shingles and eventually into your insulation and drywall. This is when you’ll start to see the leaks in your ceiling and walls.

The best way to avoid this problem is by taking preventative measures. I get calls from homeowners to remove ice dams after every winter storm, and for many, it is too late and they are already facing thousands of dollars worth of damage. But if you’re lucky enough to catch an ice dam before it fully forms, it’s a smart idea to get rid of it as quickly as possible.

Firstly, when you’re clearing snow from your driveway and sidewalks, think about your roof too. Removing snow from the house is the best way to protect your home against ice melting and refreezing in the gutters and up the roof. If you already have an ice dam forming, you can use a hammer and chisel to get rid of it, but be very careful as roof shingles are more delicate and brittle in cold conditions. One safe home remedy is to fill a pair of pantyhose with ice melt and lay it across the ice dam so the water will melt into the gutter. If you’re not comfortable on a ladder, call a professional to help you get rid of the ice dam quickly and 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. 

To all of my readers, may you have a wonderful Christmas and holiday season. I look forward to seeing you in the New Year.

Chilly Temperatures Going Through the Roof

After some more chilly temperatures and another burst of snow, people all around town are getting tired of being cold in their homes. This week, I received a call from a reader who took it upon himself to go up into the attic to check his insulation. Guess what he found? Icicles hanging from the rafters!

It might be hard to believe that icicles can form inside the house, but in many older homes that lack proper insulation and ventilation, the attic can become a magnet for condensation, which will freeze when it gets cold enough and the moisture has nowhere to go.

We all know that heat rises, and when we heat our homes in the winter, a lot of that warm air moves up through our ceilings and into the attic, rising all the way up to where it should be able to pass through the vents to the outside. However, if those vents aren’t working properly, the condensation and air have nowhere to go, so it collects on any cold surface below the dew point and turns into frost. After a while, this frost builds up to form icicles. The more moisture that builds up in the attic, the worse the problem will become. As temperatures rise and that ice and frost start to melt, it can saturate your insulation with water, causing mold and mildew problems as well as potential leaks in your ceiling. What’s worse is this isn’t even just a winter problem. Condensation build up can cause issues in your attic all year long.

So how do you stop the condensation from forming? Your first move is to look for places that are leaking warm air into the attic. If you have a whole house fan, it’s a wise move to cover it as the louvers are letting your valuable heat escape. Bathroom fans are another sure bet for letting air through and they will cause major condensation issues if they are blowing into the attic instead of venting directly outside. Finally, make sure your folding stairway is covered over with an insulated box or weather stripping to avoid losing that extra heat.

While sealing off places that allow heat to get into the attic is a great idea, the one thing you never want to do is seal off your attic vents. Attic ventilation is a system which includes intake vents in the soffit and exhaust vents at the roof’s ridge. If these vents get sealed or blocked, there is nowhere for the condensation to go, so it gets trapped and can easily manifest into a leak. Believe it or not, the average family of four generates two gallons of water vapor each day from cooking, cleaning, showering, laundry, and breathing. If that water is left sitting in the attic, you’re going to have a problem.

These freezing temperatures give you a great opportunity to take a look up in your attic to see if you have any frost or icicles culminating in your home. It’s a problem that you don’t want to leave alone unless you want to deal with potential leaks come spring.

Simple Sealing Solutions to Retain Lost Heat in the Home

Old, drafty windows can be a killer this time of year - both in terms of comfort and cost. Cranking up the thermostat to combat escaping heat can often double or even triple your energy bills, plus it makes your heat and cooling systems go into overdrive which can shorten their lifespan.

While I am a huge fan of the latest and greatest energy efficient windows on the market, I understand that sometimes replacing that old glass isn’t in the budget. Keeping this in mind, I wanted to give you a few tips to help you retain some of the heat you’re losing from those old windows.

First, it’s important to remember that windows are one of the biggest sources of air leaks, which is a big deal in two of our four seasons. In the cold weather they let the heat escape, and in the warm weather they let it in, making your climate control systems work much harder than they have to. While the simple solutions I've outlined below will help you retain some comfort, window replacement will be your best bet long term if you’re tripling your energy bill during certain months of the year. So let’s get to the tips:

1. Put up curtains. Believe it or not, hanging heavy fabric drapes can help you retain up to 25% of the heat in your home. This is especially true with large glass doors that aren’t being used in the winter months. The fabric acts as a barrier and while it won’t stop the air from getting out, it will slow the leakage. Plus, they can be very helpful in the summer, especially if your house gets a lot of direct sunlight.

2. Seal up gaps. Wooden window frames get warped with age and can lead to serious air leakage. For cracks that are smaller than a quarter of an inch, a silicone caulk will work to plug up areas where air can flow through. For larger gaps and places that need to still open and close, weatherstripping is an excellent solution. It comes in foam, felt, vinyl and other materials and is both cost-effective and easy to install.

3. Add a layer. Single pane windows in homes that were built more than 50 years ago simply can’t stand up to our cold winters. If you feel air coming right through the panes and the glass rattles with the wind, beef them up with some heat shrink film. This product can be found at any home supply store and can be cut to fit just about any pane. Using heat from a hairdryer, the plastic adheres to the glass, giving you a little bit of extra protection against the cold.

4. Close up the attic. While not a window, people with an attic hatch are likely losing a ton of warm air through its frame. We all know that hot air rises, so seal up that hatch with heavy duty plastic, or build yourself an insulated box to fit over the entryway if you still need access to storage.

5. Don’t forget the doors. We don’t often open the windows in the winter, but doors are a different story. They let lots of air escape, but they can’t be sealed completely because we need to use them. I always suggest inspecting your door sweep to ensure it’s not damaged, and replace it if the bristles have come loose. A door snake or seal can also come in handy, which can be purchased at any big box store or even made at home with an old pair of tights and some rice, beans, newspaper or another filling.
