When winter arrives, many of us are focused on holiday preparations, cozying up indoors, and keeping warm. But while you’re tucked inside enjoying the season, your roof is hard at work defending your home against the elements. Here in Vermont we are no strangers to harsh weather, thats why Vermont Constructions Roofing Division is open year round ensuring speedy repairs and replacements when it matters most.
Winter roofing can be a bit more challenging than other seasons, so it’s essential to understand how cold weather impacts your roof and how to protect it. Let’s take a closer look at some key considerations for roofing during the winter and how to ensure your home stays secure and comfortable.
Ice Dams: A Major Winter Roofing Concern.
By mid-winter, ice dams are a significant risk for many homeowners. These ridges of ice form at the edge of the roof when the snow that sits on top of your home melts, travels down the roof, and refreezes in the colder areas near the eaves. This cycle can trap water on the roof, causing it to back up under the shingles and potentially leak into your home. Ice dams can lead to extensive water damage, particularly in your attic, walls, and ceilings.
How to Handle Ice Dams Mid-Winter:
- Use Roof Heating Cables: If ice dams are a recurring issue, installing heat cables along the roof’s edge can help prevent snowmelt from refreezing and forming ice dams. The cables will warm the roof just enough to keep water flowing off the roof rather than pooling.
- Inspect for Ice Dams: Take a moment to check your roof for visible signs of ice dams. If you notice icicles hanging from your roof’s edge, it could indicate an ice dam is forming beneath them.
- Ensure Proper Attic Insulation: Inadequate attic insulation and ventilation are often the primary causes of ice dams. If warm air escapes from your home into the attic, it can cause the snow on your roof to melt prematurely. Make sure your attic is well-insulated to prevent heat from escaping and to keep the roof cold enough for snow to stay frozen.
Heavy Snow Accumulation: Assessing the Load on Your Roof.
Mid-winter can bring heavy snow, which can accumulate on your roof over time. While many roofs are designed to handle the weight of snow, excessive accumulation can put added strain on the structure, leading to sagging, damage, or even a roof collapse in extreme cases.
What to Do About Snow Build-up:
- Check for Excessive Snow Load: Inspect the snow on your roof for signs of excess weight. If you live in an area with frequent snowstorms, it’s a good idea to regularly monitor your roof after each snowfall.
- Remove Snow Safely: If snow has built up to a depth of 12 inches or more, consider removing it, especially if your roof is flat or you notice any sagging. You can use a roof rake to clear the snow from the eaves and edges, but make sure to do this carefully and avoid climbing onto the roof yourself.
Wind Damage and Loose Shingles.
Vermont winters almost certainly bring strong winds, especially during snowstorms and cold fronts. These winds can rip off shingles or damage roofing materials, leaving your roof vulnerable to leaks. Even if your roof appeared fine at the beginning of winter, strong gusts can loosen or dislodge shingles, especially if they were already weakened by earlier storms or brittled by extreme temperatures.
What to Do About Wind-Damaged Roofs:
- Address Issues Immediately: If you find damage to your roof, it’s important to address it as soon as possible. Even small gaps in the roofing can allow water to penetrate and freeze, causing further damage.
- Check for Missing or Loose Shingles: After a particularly windy storm, check your roof (from the ground or through binoculars) to see if any shingles are missing or loose. Even minor damage can lead to leaks if not addressed promptly.
- Inspect Flashing and Vents: Pay special attention to roof flashing, vents, and chimneys, as these areas are most susceptible to wind damage. Ensure that all seams and connections are sealed properly to prevent water from entering.
Frozen Gutters and Downspouts.
By mid-winter, gutters and downspouts can become clogged with ice and snow, preventing water from draining off the roof properly. This can exacerbate ice dam issues, contribute to water backing up onto the roof, and lead to leaks inside your home.
How to Prevent Gutter Damage:
- Clear Gutters and Downspouts: If you haven’t already, clear your gutters of any leaves, debris, or ice. In freezing temperatures, water can get trapped in gutters and refreeze, creating an ice blockage. This will prevent proper water drainage and can result in the formation of ice dams.
- Check for Ice Buildup: Use a ladder to safely inspect your gutters and downspouts for signs of ice buildup. If you notice an ice blockage, you can try to gently remove it using warm water (not hot, as this could cause damage) or hire a professional to do the work.
Address Leaks Promptly.
Leaks can develop during the winter, especially after a storm or if there’s already damage to your roof. If you notice a water stain on your ceiling or walls, there’s a good chance your roof has been compromised, and water is finding its way inside.
What to Do About Roof Leaks:
- Check for Water Stains: If you notice water stains in your attic or ceiling, it’s time to investigate further. Leaks can occur around flashing, chimneys, or damaged shingles.
- Temporary Repairs: If you can safely access the area of the leak, you can cover it temporarily with a tarp or roofing sealant to prevent further water damage. However, this is only a temporary fix, and you should contact a roofing professional to make more permanent repairs.
- Hire a Professional: If you’re unsure of the source of the leak or if it’s difficult to access, it’s best to hire a roofing professional to assess and repair the damage. Repairing leaks during the winter can be challenging, but experienced roofers have the tools and expertise to handle these conditions.
Conclusion
As we reach the heart of winter, it’s essential to stay proactive when it comes to roof maintenance. Mid-winter brings unique challenges like ice dams, heavy snow accumulation, and wind damage, all of which can compromise the integrity of your roof and your home. By addressing these concerns early, performing regular inspections, and seeking professional help when needed, you can protect your home from the coldest months and ensure your roof stays in good condition until spring arrives.
