10 Last-Minute Ways to Protect Your Home During Extreme Cold

We’ve spent the last couple of weeks talking about frozen pipes and ice dams, and unfortunately, this weekend is shaping up to be the coldest stretch of the year. When temperatures drop this low, small oversights can turn into expensive problems fast.

The good news? You don’t need to panic or run out and spend a fortune to help your home ride out extreme cold. A few simple, last-minute steps can make a real difference now and help prevent bigger repair bills down the road.

Here are 10 practical things you can do before (and during) a deep freeze.

1. Let faucets drip just a little

A slow, steady drip keeps water moving through pipes, making them far less likely to freeze. Focus on faucets connected to exterior walls, especially in kitchens, bathrooms, and laundry areas.

2. Open cabinet doors under sinks

This allows warm air from your home to circulate around plumbing. It’s simple, free, and surprisingly effective, especially overnight when temperatures hit their lowest point.

3. Turn the thermostat up a few degrees

This isn’t the weekend to save on heating costs. A slightly warmer house helps protect pipes in walls, basements, and crawlspaces. Consistent heat is better than dramatic temperature swings.

4. Check that vents and returns aren’t blocked

Furniture, rugs, or curtains blocking vents can reduce heat circulation, creating cold pockets near exterior walls. Make sure warm air can move freely throughout your home.

5. Seal obvious drafts (temporarily is fine)

If you feel cold air coming in around doors or windows, stop it now. Towels, draft snakes, or temporary weatherstripping can help seal gaps quickly and cheaply until permanent fixes can be made later.

6. Make sure attic hatches are closed and sealed

An open or poorly sealed attic hatch allows warm air to escape, cooling your home and contributing to ice dam formation. Even a quick check can help keep heat where it belongs.

7. Clear snow away from foundations and vents

Snow piled against your house can refreeze and cause ice buildup near foundations. Also check dryer vents, furnace exhausts, and intake pipes to make sure they’re clear and functioning properly.

8. Avoid shutting off heat in unused rooms

Closing doors and turning off heat may seem logical, but it can actually increase the risk of frozen pipes in those areas. Keep temperatures consistent throughout the house.

9. Know where your main water shutoff is

This doesn’t cost a dime but it’s critical. If a pipe does burst, shutting off the water quickly can dramatically reduce damage. If you’re not sure where it is, take five minutes to find it now.

10. Don’t ignore warning signs

Unusual drafts, dripping sounds, frost on pipes, or doors suddenly sticking can all be early indicators of cold-weather stress on your home. Addressing small issues now can prevent major repairs later.

A quick reminder

Extreme cold tests even well-maintained homes. These steps aren’t about perfection, they’re about reducing risk and giving your house the best chance to get through a tough weekend unscathed.

If you’ve already dealt with ice dams, frozen pipes, or winter damage in the past, it may be worth having a professional take a look once temperatures rise. Preventative maintenance is almost always cheaper than emergency repairs.

Stay warm, stay safe, and let’s all get through this cold snap without any surprise phone calls to our insurance companies.

When (and How) to Shovel Your Roof After Heavy Snow

If it feels like we’ve been living inside a snow globe lately, you’re not imagining it. Connecticut has taken a serious beating this week, and while most of us have been focused on clearing driveways and walkways, there’s another place snow quietly causes trouble: your roof.

Last week, we talked about ice dams, those thick ridges of ice that form along the roof edge and trap melting snow, often forcing water back under shingles. One of the best ways to prevent ice dams is also one of the most overlooked winter maintenance tasks: roof shoveling.

So when should you shovel your roof, why does it matter, and how do you do it safely (or decide not to do it yourself at all)?

When to shovel your roof

There’s no hard-and-fast rule like “six inches equals shovel time,” but there are some clear signals. If your roof has accumulated a foot or more of snow, especially heavy, wet snow, it’s worth paying attention. The same goes if you’re seeing icicles forming along the eaves, uneven snow melt, or signs of ice dams starting to build.

Older homes, homes with flatter or low-pitch roofs, and houses with less insulation or ventilation tend to be more vulnerable. And if we’re in one of those cycles where snow melts during the day and refreezes at night (hello, New England winter), snow buildup becomes more than just a cosmetic issue. It becomes a structural and water-infiltration risk.

Why roof shoveling matters

Snow is deceptively heavy. A roof holding several inches of wet snow can be supporting thousands of extra pounds. Over time, that stress can contribute to sagging, cracks, or long-term damage, especially if your roof was already nearing the end of its lifespan.

But the bigger issue for many homeowners is water. Snow melts, water moves, and when it refreezes at the roof edge, it has nowhere to go. That’s how you end up with leaks, stained ceilings, peeling paint, and mold growth, sometimes weeks after the snow is gone.

Roof shoveling reduces the amount of snow available to melt and refreeze, helping to prevent the ice dam cycle we talked about last week before it starts.

How to shovel your roof safely

If you’re going the DIY route, safety comes first. You should never climb onto a snow-covered roof. Instead, use a roof rake with a long extension and work from the ground. Pull snow down gently, starting at the roof edge and working upward a few feet at a time.

The goal isn’t to scrape the roof bare. In fact, you don’t want to. Leave a thin layer of snow to avoid damaging shingles. And always be aware of what’s below—snow and ice come down fast and heavy, and no one wants a surprise avalanche landing on them or their landscaping.

If your roof is steep, high, or difficult to access, or if ice has already formed, that’s your cue to stop.

When to call a professional

There’s no prize for doing this yourself. Roof shoveling can be dangerous, and every winter, people get hurt trying to save a few dollars. A professional has the right tools, safety equipment, and experience to remove snow and ice without damaging your roof or themselves.

Many local home improvement companies like ours offer roof shoveling during heavy snow seasons. We already understand roofing systems inside and out, can assess whether snow removal is necessary and handle it safely when it is. That kind of experience matters, especially when ice dams or existing roof issues are in play.

Roof shoveling isn’t something most homeowners think about until there’s a problem. But paired with good insulation, ventilation, and awareness (like spotting ice dams early), it’s one more way to protect your home during a tough Connecticut winter.

If you’re unsure whether your roof needs attention, trust that instinct or call a pro. It’s always better to address snow buildup proactively than to deal with water damage once everything melts.

Ice Dam Prevention This Winter

If this winter feels unpredictable, you’re not wrong. We’ve been experiencing a familiar but frustrating pattern: cold temperatures and snow followed by milder daytime weather, then freezing again overnight. That constant freeze-thaw cycle is the perfect recipe for ice dams, even in years when snowfall totals are relatively modest.

Ice dams form when snow accumulates on a roof and begins to melt during warmer daytime temperatures. Heat escaping from the home, often through an under-insulated attic, warms sections of the roof just enough to melt the snow. The water then runs down toward the eaves and gutters, where roof temperatures are colder. As nighttime temperatures drop, that water refreezes. When this melting and refreezing happens repeatedly, a thick ridge of ice builds up along the roof edge, creating an ice dam.

These icy barriers don’t just sit harmlessly at the edge of your roof. They block proper drainage, forcing melting snow to back up under shingles. That water can seep into the attic, soak insulation, stain ceilings, damage walls, and create conditions that encourage mold growth. The weight of the ice itself can also pull gutters away from the house or loosen shingles, opening the door to even more water damage.

Homeowners should watch for early warning signs. Large icicles hanging from gutters, uneven snow melt across the roof, or water stains appearing on interior walls during winter are all indicators that heat is escaping and ice dams may be forming.

When ice dams appear, many homeowners are tempted to take matters into their own hands, but this is where things often go wrong. One of the most common mistakes is hacking away at ice with a shovel, axe, or ice chopper. While it may feel productive in the moment, this can easily damage shingles, puncture the roof, or dent gutters, leading to repairs that cost far more than the ice dam ever would have. Another risky approach is climbing onto an icy roof without proper safety equipment. Slips and falls are a serious hazard during winter and can result in severe injury.

Chemical deicers can also cause problems if used improperly. Products not designed specifically for roofs may damage shingles, kill nearby landscaping, or corrode metal gutters. Even roof-safe deicing products should be used cautiously and viewed as a temporary measure, not a long-term solution.

The real fix for ice dams isn’t on the roof at all. It starts in the attic. Proper insulation and ventilation help keep roof temperatures consistent, preventing snow from melting unevenly in the first place. Unfortunately, more than 75% of New England homes are under-insulated, often because they were built before modern energy standards were in place. As a result, heat escapes easily, setting the stage for ice dam formation.

Improving insulation helps keep warm air inside the living space where it belongs, while proper ventilation allows cold air to circulate in the attic and keeps the roof surface cold. Together, these upgrades not only reduce the risk of ice dams but also improve comfort year-round and lower energy bills. They can also help reduce moisture buildup in the attic, decreasing the likelihood of mold and mildew.

With today’s increasingly unpredictable winter weather, ice dams are no longer just a problem after major snowstorms. Repeated freeze-thaw cycles mean they can form quickly and unexpectedly. Addressing insulation and ventilation now, before damage occurs, is one of the smartest investments a homeowner can make.
