Winter can be a magical time of year, with sparkling snowfalls and cozy nights by the fire. However, as beautiful as it may be, winter weather can take a toll on your home, especially your roof. And if you live in Northwest Indiana winter also brings brutally cold temperatures that can cause issues in themselves.
Snow can damage a roof primarily by adding significant weight, which can stress the roof's structural integrity, leading to potential issues like sagging, cracks, leaks, and even collapse. If left unchecked, leading to costly repairs and potential safety hazards.
Here’s what you need to know about how snow and ice can damage your roof and what steps you can take to prevent or address the damage.
Excess Weight from Snow
Heavy snow accumulation can place significant stress on your roof. Most roofs are designed to handle a certain amount of weight, especially that of snow, but excessive snowfall can exceed this limit, potentially leading to structural damage or even collapse.
Most residential roofs in good condition can typically hold around 20 pounds of snow per square foot, or several feet of fresh light snow, but wet, packed snow can reach a much higher weight, faster and pose a greater risk of roof collapse if it already has some damage and safety concerns.
Shingle damage
The weight of snow can cause shingles to crack, buckle, or even detach from the roof deck, especially if they are old or damaged.
Ice Dams
Ice dams occur when snow melts on your roof and refreezes at the edges, creating a barrier that prevents proper drainage. This trapped water has to go somewhere and can seep under shingles, leading to internal leaks, water damage under the roof and inside the home, and even mold.
Freeze-Thaw Cycles
During the day, sunlight can cause snow to melt, and overnight temperatures can cause the water to freeze again. This cycle can lead to the formation of cracks in roofing materials, especially in asphalt shingles, making your roof more vulnerable to water infiltration.
Gutter Damage
The extra weight of ice and snow can strain your gutters, causing them to sag, detach, or become blocked. This not only affects water drainage but can also lead to ice buildup that further damages your roof.
Ice dams don’t only damage the roof but can also disrupt the integrity of gutters.
Wind-driven Ice
In severe storms, strong winds can drive ice and snow under shingles or flashings, creating hidden vulnerabilities that can worsen over time.
Factors that can increase the risk of roof damage
Poor roof maintenance:
A roof with missing shingles, damaged flashing, or clogged gutters is more susceptible to snow damage.
It’s important, and worth the $150, or so, fee to have a professional come out and inspect your roof in the spring to catch any damage early before warmer temperatures exacerbate issues that occurred during winter.
Roof design:
Flat or low-pitched roofs tend to accumulate more snow and are more prone to damage.
This is why when you replace the roof it’s important to invest in a “re-pitch” to create additional slant that will help the elements roll down and off the roof.
Climate conditions:
Areas, like Northwest Indiana, with winters of heavy snowfall and frequent freeze-thaw cycles are at higher risk for potential roof damage.
What to Do About Snow and Ice Damage
Schedule Regular Roof Inspections
In the spring after winter or in the fall, have a professional inspect your roof for any vulnerabilities, such as missing shingles, damaged flashing, or weak spots. Addressing these issues early can save you from bigger problems later.
Scheduling early and not well into the winter season allows adequate time for repairs or replacement while also keeping roofing workers safe. It also reduces the risk of an extreme weather event occurring during replacement.
Clear Snow Safely
In theory, you shouldn’t have to clear your roof, but if it is flat or low pitched you may need to consider doing so. Use a roof rake or hire professionals to remove excess snow from your roof safely. Avoid climbing onto the roof yourself, as icy conditions can make it extremely dangerous.
Prevent Ice Dams
Ensure your attic and roof are properly insulated and ventilated to prevent heat from escaping and melting the snow unevenly. Consider installing heat cables in problem areas to keep ice from forming.
Maintain Your Gutters
Keep gutters clean and free of debris to promote proper drainage. Installing gutter guards can also help reduce ice buildup.
If you have trees close to the house or limbs that fall over the house, it is recommended to address gutters in the fall or start of winter when the trees have shed all of their leaves.
Repair Damage Promptly
If you notice leaks, sagging gutters, or other signs of damage, address them immediately to prevent further issues. Delaying repairs can lead to more extensive and costly damage. Call a professional as soon as you experience or see any potential damage. Even if the weather limits their ability to fully repair or replace the roof, they can create a solution that can tie you over until the weather is more fitting and safe.
Conclusion
Your roof is your home’s first line of defense against the elements, and winter weather poses unique challenges between the wetness of snow and freezing temperatures. By understanding the risks associated with snow and ice and taking proactive steps to mitigate them, you can protect your roof and your home from winter’s worst while also saving yourself the headaches and money of unexpected emergencies.
Don’t wait until a small issue becomes a major problem—take action now to ensure your roof stays in great shape for years to come.
