Common Roofing Problems Caused By Michigan Winters

If you’ve lived in Michigan for even one year, you’re bound to understand just how harsh the winter months can be. Not only are the freezing temperatures and heavy snowfall going to have their effects on your day-to-day life, but they can also cause significant problems for your home. And oftentimes, your roof is going to take the brunt of the damage. Between that heavy snow, ice accumulation, strong winds, and continuous freeze-thaw cycles, your roof is going to be under a lot of duress during a typical Michigan winter. Because of that, understanding the common roofing problems caused by Michigan winters is worth it, as it can help you prepare for what’s to come and effectively resolve any problems that do arise when the weather is at its harshest.

Roofing Problems Commonly Caused By Michigan Winters

The winter months in Michigan can cause the following problems for your home’s roofing system:

Ice Dams & Water Backup

Perhaps the most common roofing problem caused by Michigan winters is the formation of ice dams. When warm air escapes from your attic and melts snow on the roof, water may flow downward and when it ultimately refreezes, it creates a ridge of ice that prevents proper drainage. And once an ice dam forms, melting snow has nowhere to go, which can back water up beneath your roof’s surface and allow it to seep into the roof’s deck, insulation, and interior walls. The results from that may be ceiling stains, peeling paint, damaged insulation, and even mold growth.

Heavy Snow Load & Structural Issues

As light and fluffy as snow may look and even feel, it can certainly accumulate quickly over a short period of time and become much heavier. As it accumulates on your roof specifically, it can add significant weight to your roof, which can put a lot of stress on its structural integrity. Over time, the added weight from heavy snowfall can cause your rooflines to sag, create cracks in the roof’s structure, or weaken the support systems within your roof. Complete collapses due to heavy snow loads are rare, but not impossible, especially after repeated bouts of heavy snowfall winter after winter.

Freeze-Thaw Damage

One of the other common issues that come with Michigan winters, like ice dams, are the effects of constant freeze-thaw cycles. This can cause damage directly to your roof’s materials, as snow melting during the daytime may lead to moisture seeping into small cracks within your roof. And then, when temperatures drop overnight, that moisture freezes and expands, which can widen cracks and loosen the materials on your roof’s surface. This is a particularly damaging problem for shingle roofs, as you may see shingles curl, crack, or lose protective granules after repeated freeze-thaw cycles. Fasteners may also loosen, while underlayment can deteriorate as well. Over time, freeze-thaw damage can accelerate your roof’s aging and shorten its lifespan as a whole.

Wind Damage

As much damage as the snow, ice, and freezing temperatures can do to the roof of your home during a standard Michigan winter, don’t forget about the strong winds that these months bring as well. Because the cold temperatures can already make your roof—especially if it’s a shingle roof—more brittle, high wind speeds can soon cause cracking, breaking, or lifting. The after-effects of this can be just as problematic, as exposed underlayment and damage along the roof’s edges and ridges leave it vulnerable to more significant damage if it’s not addressed promptly.

Gutter & Downspout Damage From Ice & Snow

Michigan winters can do plenty to damage your roof itself, but there are also the secondary aspects of your system to worry about when the temperatures drop and heavy snow begins to fall. Your gutters, for example, are supposed to play a crucial role in directing water away from your roof and your home’s foundation. But as ice buildup adds weight to gutters, they may begin to sag or pull away from your roofline, jeopardizing their ability to carry out their essential function. Not only that, but any ice dams that form within the system itself can cause blockages, preventing proper drainage and leaving water and ice to pool on your roof and around your home’s foundation, leading to further problems.

Attic Condensation & Moisture Issues

Warm indoor air naturally rises and can enter your attic if insulation is poor. When the warm air meets the cold surface of the roof, that can form condensation, which is a problem—especially if it goes unnoticed or is left alone for too long. Excess moisture in your attic can dampen insulation, cause wood rot, and may lead to mold or mildew growth.

Flashing Failures & Leak-Prone Areas

Your flashing is supposed to protect vulnerable areas of your roof such as chimneys, vents, skylights, and valleys. But in the wintertime, snow and ice may linger longer around these areas, and with freeze-thaw cycles being an ongoing problem, flashing and/or sealants may begin to crack, loosen, or pull away. And when that happens, even a small gap within your roof can allow moisture in and cause further damage.

How You Can Combat Common Roofing Problems Caused By Michigan Winters

Perhaps the biggest key to working against the roofing problems that can be caused by wintertime in Michigan is to invest in preventative maintenance. That means scheduling routine inspections before and after winter is a big help, plus it’s always wise to invest in proper attic insulation and ventilation. There are always other measures you can take, too, such as installing ice and water shields, keeping your gutters clean and clear, and addressing the small repairs your roof needs before they become bigger issues.
