What to Look for on Your Roof with Heavy Snowfall

Waking up to a fresh blanket of snow can feel magical—until you start thinking about what that snow is doing to your roof. While winter weather creates a picturesque landscape, it also brings significant risks to your home’s structural integrity. Heavy snowfall, ice accumulation, and fluctuating temperatures can all cause roof damage that, if left unchecked, may lead to costly repairs or even dangerous structural failures.

At True Line Roofing, we want to ensure that your home is protected from the harsh winter conditions. That’s why we’ve put together this guide on what to look for after heavy snowfall and how to prevent long-term damage.

How Snow Can Damage Your Roof

You might not realize it, but snow is incredibly heavy—especially when it starts melting and refreezing. On average, one foot of fresh snow weighs about 5 pounds per square foot, but wet, compacted snow can weigh up to 20 pounds per square foot. This weight puts stress on your roof’s structure, and if too much snow accumulates, it can cause roof sagging, leaks, and even collapse in extreme cases.

Another major concern is ice dam formation. As heat escapes from your home, it causes the snow on your roof to melt. This water runs down to the edges of your roof, where it refreezes, forming a ridge of ice. Over time, these ice dams grow, blocking proper drainage and forcing water underneath your shingles. This can lead to leaks, water damage inside your home, and even mold growth in your attic and walls.

Fluctuating temperatures also create a freeze-thaw cycle, which can weaken your roof materials over time. Water from melting snow seeps into small cracks and crevices, and when it refreezes, it expands, making these cracks larger. Over time, this can cause shingles to loosen, flashing to separate, and overall structural integrity to weaken.

Signs of Roof Damage After Heavy Snowfall

Knowing what to look for can save you from expensive repairs down the line. After a heavy snowfall, here are some key warning signs that your roof may be compromised:

Leaks or water stains on ceilings and walls – If you notice brown spots or damp areas inside your home, your roof may be leaking due to ice dams or excessive moisture buildup.
Sagging rooflines or ceilings – A roof under too much stress from heavy snow may start to sag, which is a serious structural issue that needs immediate attention.
Difficult-to-close doors and windows – Changes in your home’s structure from roof stress can make it harder to shut doors and windows properly.
Large icicles forming on gutters and roof edges – While icicles may look pretty, they often indicate the presence of ice dams, which can cause significant damage if not addressed.
Cracking or creaking sounds from the roof – These noises can be an early sign of stress on your roof’s framing due to excess weight.
Missing or damaged shingles – Strong winter storms, combined with the weight of heavy snow, can loosen or dislodge shingles, leaving your home vulnerable to leaks.

If you notice any of these issues, it’s important to act quickly. Small problems can turn into major disasters if left untreated.

Preventing Snow-Related Roof Damage

Prevention is always better (and cheaper) than repairs. Here are a few steps you can take to minimize the risk of winter-related roof damage:

** Do NOT get on your roof please. Call for professional assistance. **

1. Remove Excess Snow from Your Roof

After a heavy snowfall, consider using a roof rake to gently remove excess snow from the edges of your roof. This helps prevent ice dams from forming and reduces the overall weight burden on your roof. However, be cautious when doing this yourself—never climb onto a snow-covered roof, as it can be extremely slippery and dangerous. If the snow is deep or heavy, it’s best to call in a professional.

2. Keep Gutters and Downspouts Clear

Your gutter system plays a crucial role in directing water away from your roof and home. Before winter sets in, make sure your gutters are clean and free of debris. Blocked gutters can cause water to back up and freeze, leading to ice dam formation and potential damage to your roof and siding.

3. Check Your Attic for Proper Insulation and Ventilation

Poor insulation and ventilation in your attic can contribute to snow melting and refreezing, leading to ice dams and leaks. A properly insulated attic keeps heat from escaping through the roof, reducing the risk of uneven snowmelt. Good ventilation helps regulate attic temperature and prevents condensation from forming, which can lead to mold growth and wood rot.

4. Schedule a Winter Roof Inspection

Regular roof inspections can help catch potential problems before they become costly repairs.
