The Most Common Winter Roofing Issues to Watch For

The roof may not be the most glamorous part of a house, and it’s often an element we barely notice at first. Unlike the front door we use daily or windows that bring in natural light and views, the roof tends to go unnoticed—until something goes wrong. This oversight can lead to serious issues, as neglecting roof maintenance is a costly mistake.

Your roof is not only your home’s first line of defense against the elements, but it also plays a critical role in maintaining structural integrity, longevity, and cost-efficiency. With winter approaching, bringing snow, rain, and freezing temperatures, now is the time to pay close attention to your roof.

Winter is notoriously hard on roofs; in fact, in 2024 alone, winter weather has already caused $61.8 million in property damage across the U.S. Understanding common causes of winter roof damage and how to prevent them can save you from costly repairs and related issues like structural damage and mold.

Often, you don’t realize you have winter roof damage until you’re facing expensive repairs. Knowing the most common winter roofing issues—and how to prevent them—will save you time, stress, and money. Let’s dive into the typical winter roof problems and some easy steps to keep them at bay.

Ice Dams

Ice dams—accumulations of ice at the edges of sloped roofs—form when snow on your roof melts and then refreezes. This creates a barrier that prevents proper drainage, causing water to get under shingles, which can lead to leaks and interior damage.

5 Tips to Prevent Ice Dams From Forming

The key to preventing ice dams on your roof is proper insulation, ventilation, and regular maintenance of your gutters. Here are some practical steps you can take to safeguard your roof from ice dams:

1. Boost Your Attic Insulation

Start with good attic insulation to keep those pesky ice dams at bay! The recommended insulation level, known as R-value, for Delaware homes is between 38 and 60. Proper insulation will help maintain a steady roof temperature, which helps prevent the melting and refreezing that causes ice dams.

2. Seal Air Leaks

Keep that cozy warmth inside where it belongs! To prevent fluctuating temperatures in your attic, you’ll have to keep warm air from escaping from the lower levels of your home. You can do this by sealing around electrical cables and vent pipes with fire-stop sealant, wrapping ducts with insulation, and covering attic hatches.

3. Maintain Your Roof & Gutters

A little winter maintenance can save you big headaches later. Clear leaves and debris from gutters to maintain proper water flow. After heavy snowfall, use a roof rake to remove snow from the edges of your roof, and check gutters for snow or ice buildup.

4. Ensure Proper Ventilation

Proper ventilation also helps prevent ice dams by keeping your roof temperature consistent. Ensure good airflow from the soffit area (the horizontal boards under your roof’s overhang) up through roof vents to avoid warm air melting snow on the roof. This setup also helps to control moisture, protecting your roof from ice dam buildup.

5. Install Protective Measure

Want extra peace of mind? Here are some proactive measures you can take when you’ve done all the steps above but find your roof is still prone to ice dams:

• Install heated roof cables along the edge of your roof to keep ice from building up.
• Add a waterproof underlayment beneath your shingles to stop leaks if an ice dam does form.
• Incorporate metal ice belts or panels, which let ice slide right off your roof and keep your home protected.

Condensation

Condensation occurs when warm air from inside the home meets the cold roof surface, leading to moisture buildup that can damage your roof and promote mold growth. Thankfully, the same steps you take to insulate and ventilate your attic for ice dam prevention can also help prevent condensation.

Additional Tips to Prevent Winter Roof Condensation

• Use exhaust fans in bathrooms and kitchens to reduce indoor humidity.
• Add vapor retarders on roofing substrates to block moisture.
• Schedule regular roof inspections to catch and address any signs of condensation.

Flashing Leaks

Flashing, the material around chimneys, skylights, and roof edges, is particularly vulnerable to winter weather. When flashing becomes loose or damaged, it can lead to leaks. Regular professional inspections are essential to spot any flashing issues early.

Prevent Flashing leaks

To prevent winter leaks, schedule regular roof inspections to identify wear or corrosion. A professional roof repair service can swiftly patch holes and replace any damaged flashing before these issues lead to leaks. It is also important to keep gutters clear to aid in proper drainage and reduce pressure on flashing areas.

Snow Load & Icicles

Heavy snow accumulation, especially on flat roofs, can exceed your roof’s weight capacity, risking structural damage or collapse. Despite their charm, icicles on your roof can be a sign of poor insulation and drainage issues and can damage gutters and roof edges.

Prevent Icicles & Excessive Snow Load

Many of the same steps we’ve already mentioned—attic insulation, ventilation, and clear gutters—also help minimize snow load and icicle formation. Additionally:

• Use a roof rake to clear snow from the edges.
• Install heating cables for snow melting.
• For low-pitched roofs, you might consider investing in a roof replacement. A high-quality roof will enhance snow shedding and roof durability.

Tree Damage

Overhanging branches can scrape against your roof or break during storms, causing damage. Regularly trimming trees around your home can help avoid these hazards.

Prevent Winter-Related Tree Damage on Your Roof

To protect your roof from potential tree damage during winter, consider these proactive steps:

• Prune branches close to the roof to prevent breakage.
• Inspect trees for health and stability; consult an arborist for large trees.
• Monitor ice buildup on branches, as heavy ice can cause breakage.
• Plant new trees at least 15-20 feet from your home.

Your roof is your home’s first defense against winter’s harsh conditions.
