Winter weather can be very hard on your roof, especially if it hasn’t been updated in the last 20 years. Heavy snow, ice accumulation, rain, wind, and freezing temperatures can all take a major toll on the health of your shingles as well as the structure beneath them. To ensure your home remains well-protected throughout the winter, it’s important to keep a close eye on the state of your roof. At Keyprime Roofing, we know the signs of impending roof damage are not always obvious to homeowners, but as roofing experts, we know exactly what to watch for. Here’s what you need to keep an eye on throughout the winter to ensure your roof remains in top condition.



As snow and ice accumulate on your roof, condensation will inevitably develop. When warm air from within your home meets with the cold underside of your roof, moisture droplets may begin to form along the interior of the roof. If you take a trip up to your attic, you may notice signs of moisture development that can cause significant damage to the structure of your roof. If condensation goes unchecked, it can lead to mold and mildew development that may damage not only your home but also your health.


To prevent moisture accumulation throughout the winter, consider implementing a ventilation system that allows adequate airflow throughout the space. Without proper ventilation, you may shorten your roof’s projected lifespan by several years.


High Winds and Shingle Damage

Certain types of shingles are more susceptible to damage during winter storms. When high winds hit, they can loosen both asphalt and cedar shake shingles, leaving your roof open to moisture accumulation.


To ensure your roof remains fully intact throughout the winter, do your best to visually examine it on a regular basis. This may be somewhat difficult with ice and snow accumulation, but inspection is critical to avoid moisture penetration into the wood structure beneath your shingles. If you notice any damage or missing shingles, contact a roofing contractor as soon as possible. You’ll need to have those shingles replaced to ensure your roof provided adequate protection throughout the remainder of the season.


Ice Dams

Ice dams—when left unchecked—can be particularly damaging to your roof. It’s not the ice itself that causes damage, but rather the moisture accumulation beneath it that wreaks havoc on your home. If your roof was improperly installed, it could allow moisture to penetrate beneath the shingles, where it will make its way to your ceiling and walls. And even if your roof was properly installed, inadequate insulation and ventilation can contribute to roof damage as a result of ice dam formation.


You’ll want to make sure your attic is well ventilated and properly insulated to prevent uneven melting of the snow on your roof. If your roof has a history of ice dam formation, you should contact a roofing contractor to examine the structure. If it was improperly installed, a contractor can make the necessary repairs to help prevent ice dam formation and keep your home protected from water damage.


Leaking Flashings

Flashings help direct water away from critical areas on your roof that may be especially prone to damage as a result of moisture accumulation. These thin strips of metal attach on top of your shingles, and sometimes, they become loose or slightly detached. When this occurs, water can seep beneath the flashings, resulting in roof leaks.


To help prevent leaks, it’s important to inspect your flashings regularly for signs of detachment or wear. Usually, you’ll find these metal structures around skylights, chimneys, and dormers, or anywhere your roof meets a vertical structure. If you notice water leaks, contact a roofing contractor to inspect your flashings. Even if the flashings aren’t the cause of those leaks, a professional roofer can locate the source and remedy the issue.


Heavy Snow

Heavy snow presents an issue for your roof in two ways: weight accumulation on the roof itself and weight on surrounding tree branches. If the weight of the snow on your roof exceeds its snow load rating, portions of your roof may collapse or experience significant damage. For Minnesota homes, roof snow load rating is 70% of the ground snow load. Depending on daily snow accumulation, you may need to implement professional snow and ice dam removal to prevent damage.


Overhanging, frozen tree branches also present a hazard to your roof, especially if they’ve accumulated substantial snow. In winter, tree branches become much stiffer and more brittle due to freezing temperatures. When snow accumulates on a branch—especially if it’s dead—that branch can easily break away from the trunk, potentially landing on your roof. Obviously, this can result in significant damage to the structure and roof leaks. To prevent damage, make sure you trim overhanging branches before winter sets in.
