Winter brings a unique set of challenges for homeowners. From heavy snowfall to spots of condensation,  the bitter cold of winter can wreak havoc on even the most well-maintained roofs. Fortunately, by understanding the problems roofs encounter during winter and implementing the right solutions, you can minimize the risk of damage and keep your home safe and comfortable even during the coldest months of the year.

What common winter roofing issues do homeowners face?

Below are some of the most common winter roofing issues and how to solve them. However, it is crucial to emphasize that attempting to address these issues without professional help can lead to unintended consequences.

Ice dams

Ice dams are ridges of ice that form along a roof’s edge. When heat from the attic escapes, it melts the snow on the roof and causes water to trickle down. This melted water then refreezes when it encounters the colder eaves, forming an ice dam. As this process repeats, the ice dam becomes thicker and heavier.

Ice dams can damage your roof by causing it to sag and leak. They also obstruct proper drainage, leading to water seepage beneath shingles and potential water damage.

How to prevent ice dams

Improving attic insulation, such as by installing roof vents, is the best way to stop ice dams from forming. Roof vents create a natural airflow system in your attic. This airflow not only prevents warm air from collecting in your attic but also cools the roof deck, preventing the snow from melting in the first place.

Snow accumulation

Heavy snow accumulation is a common concern during winter. The excess load puts stress on your roof’s structure and can compromise the integrity of roofing materials. In extreme cases, it can cause your roof to collapse.

How to deal with snow accumulation

Clearing snow from your roof is especially important after a heavy snowfall. However, effective snow removal is a delicate process that requires caution and professional expertise. 

In addition to clearing your roof of snow, a local professional roofer can also determine if your roof is sturdy enough to support the load of snowfall in your area. In certain cases, they may advise to install roof supports, which can help distribute the weight of the snow more evenly and prevent your roof from sagging or collapsing.

Condensation and moisture

Condensation is a prevalent issue during winter, especially in poorly ventilated attics. As warm, moist air rises to the attic, it encounters colder surfaces, causing moisture to transform into water droplets. Over time, the moisture can accumulate and compromise the roof’s structural integrity by promoting rot and creating an ideal environment for mold growth.

How to control moisture

Adequate ventilation helps regulate temperature differentials and reduce the risk of condensation. Boost airflow by installing proper roof vents — this allows moisture-laden air to escape and fresh air to circulate. Also, seal air leaks with caulk or spray foam. Gaps around pipes, vents, and electrical wires can let warm air into the attic, leading to condensation. 

Professionals can assess the unique needs of your roof and recommend targeted solutions to control moisture and prevent potential damage.

Freezing and thawing cycles

When temperatures plummet below freezing point, water trapped in your roof’s shingles freezes and expands in volume, causing microscopic cracks and fissures to form. These cracks and fissures remain even when the temperature rises and the ice thaws, weakening the overall structure of the roof. With each subsequent freeze-thaw cycle, these cracks widen and deepen, leading to more significant problems.

How to protect against repeated freezing and thawing

Safeguard your roof from the effects of the freeze-thaw cycle by doing the following:

• Conduct regular inspections: Schedule annual inspections by qualified roofers to identify and repair any cracks or damage before they worsen.
• Have proper ventilation: Ensure adequate ventilation in your attic to prevent moisture buildup, which can exacerbate the freeze-thaw cycle’s effects.
• Install ice and water shield: Having this shield beneath your shingles provides an extra layer of protection against water infiltration.
• Quality materials: Choose high-quality roofing materials designed to withstand harsh weather conditions and resist the freeze-thaw cycle.
• Repair damage promptly: Don’t delay repairs to existing damage, as small problems can quickly escalate into costly issues.
