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.

What You Don’t See Can Affect You When It Comes To Winter Air Quality

When winter settles in, most of us do the same thing: shut the windows, seal the drafts, and crank the heat. It’s great for comfort and energy efficiency, but not always great for the air we breathe. With homes closed up tight for months at a time, indoor air quality can quietly take a hit, leading to discomfort and even health concerns.

The good news? A few smart habits and simple upgrades can make a noticeable difference.

Why Indoor Air Quality Suffers in Winter

Cold weather means less fresh air circulating through your home. At the same time, heating systems kick into high gear, stirring up dust and other particles that might otherwise stay settled. Common indoor pollutants during winter include dust, pet dander, mold spores, and volatile organic compounds (VOCs) released from cleaning products, paints, and furnishings.

When these pollutants build up, people may experience headaches, fatigue, sinus irritation, or respiratory issues - symptoms often lumped under the term “sick building syndrome.” If you’re feeling off all winter, your indoor air might be part of the problem.

Practical Ways to Improve Winter Air Quality

Let Fresh Air In, Yes, Even in Winter

You don’t need to leave windows wide open. Short bursts of fresh air, just a few minutes at a time, can help flush out stale indoor air. Using kitchen and bathroom exhaust fans also helps remove moisture and airborne contaminants right at the source.

Keep Humidity in the Sweet Spot

Indoor humidity should hover around 40–50%. Too much moisture encourages mold growth, while air that’s too dry can irritate your nose, throat, and skin. A humidifier or dehumidifier can help keep things balanced, especially in older homes.

Stay on Top of HVAC Maintenance

Your heating system keeps you warm and moves air throughout your home. Change filters every three months and schedule annual maintenance to keep things running efficiently. Dirty filters and neglected systems can spread dust and allergens instead of trapping them.

Use Air Purifiers Where You Spend the Most Time

A quality air purifier with a HEPA filter can significantly reduce airborne particles like dust, pollen, and pet dander. Units with activated carbon filters also help absorb odors and chemical fumes. Bedrooms and living areas are usually the best places to start.

Add a Few Low-Maintenance Houseplants

Some plants help improve indoor air quality while also making your home feel more alive during the gray winter months. Snake plants, for example, are hardy, low-maintenance, and known for their air-filtering benefits.

Choose Cleaning Products Carefully

Many conventional cleaners release VOCs that linger in indoor air. Switching to natural or low-VOC products can reduce chemical exposure. When stronger products are necessary, proper ventilation is key.

Install and Maintain Gas Detectors

Carbon monoxide and radon are invisible, odorless, and potentially dangerous. Make sure detectors are installed and functioning properly, and test them regularly, especially during heating season.

Keep Dust Under Control

Regular dusting and vacuuming go a long way. Using a vacuum with a HEPA filter prevents allergens from being kicked back into the air while you clean.

Go Easy on Scents

Candles, plug-ins, and air fresheners may smell nice, but many release VOCs. If you use them, do so sparingly and make sure rooms are well ventilated.

Breathe Easier All Winter Long

Winter doesn’t have to mean stale air and stuffy rooms. With a few proactive steps, you can protect your indoor air quality, improve comfort, and create a healthier home environment for everyone under your roof.

Unwanted Holiday Houseguests

As winter settles in, you might find yourself sharing your home with some unexpected guests. Mice, raccoons, squirrels, and even possums often look for warmer places to stay as the weather grows colder. Attics make an ideal retreat, providing shelter from the elements. If you’re hearing strange noises such as squeaks, scurrying, or even hissing, especially late at night, it’s likely that a critter has moved in.

If an animal has taken up residence, it’s important to act quickly before they get too comfortable. Once settled, they may start nesting, which can lead to further damage. Most animals leave clues that help identify them. High-pitched squeaks or chewing sounds usually mean rats or mice, while fast scurrying is often a sign of a squirrel or a mouse. Raccoons, known for their snarling and hissing, tend to make more aggressive noises. While some animals move into your attic on purpose, others may be there by accident and are simply trying to find a way back outside. Understanding what you’re dealing with can help you determine the best course of action.

Animals in your attic aren’t just a nuisance; they pose serious risks to your home. Most will gnaw on anything they encounter, especially mice and rats, which chew through wiring, creating fire hazards. Larger animals like raccoons and possums can tear apart insulation and ruin ductwork, leading to costly repairs. Their droppings and urine can also create unpleasant odors and unsanitary conditions.

If your problem is mice or rats, they likely came in looking for warmth and water. These small animals can squeeze through holes as tiny as a dime, so sealing any potential entry points and fixing leaks is essential. Setting bait traps can catch some of the rodents already inside, but long-term solutions require securing all access points to prevent re-entry.

Squirrels, on the other hand, usually prefer the outdoors and may have come into the attic by mistake. They often get in through soffits or vents. One of the best ways to help them leave is by installing an exclusion door - a one-way exit that allows them to leave but not return.

Raccoons are more determined and will stay put if they find a warm, dark spot. Since they’re nocturnal, try leaving lights on in the attic and playing music to encourage them to find somewhere quieter to rest.

Bats are trickier, as they’re usually very quiet unless there’s a large colony present. Due to potential health risks, bat removal should only be performed by a certified DEEP specialist.

Finally, possums, much like raccoons, are resilient squatters that often refuse to leave. Their droppings can quickly accumulate, leaving a huge mess and a foul odor. The best way to handle a possum is to call a professional for humane trapping and removal.

Ultimately, dealing with unwanted animal visitors is best left to professionals. Ignoring the problem can result in more than a few sleepless nights; it can lead to extensive and costly repairs.
