How to Prevent Three Common Winter Roofing Hazards

Winter can be tough on your roof,but you don’t need us to tell you that. From high winds to large snow loads, it puts up with a lot to keep your family safe. Unfortunately, though, even the most well-made and well-maintained roof can take a hit from our state’s crazy weather, and when temps surge below zero, a faulty roof isn’t just an inconvenience—in the right circumstances, it could be downright life-threatening.

The good news: many winter roofing hazards are easily available; you just need to know your enemy, so to speak. Below, GCM Construction & Maintenance is here to help you do just that with a post on how to sidestep some common cold-weather conundrums.

Ice Dams

Caused when snow melts on your roof, rolls down to the eaves, and refreezes, these nasty formations result in puddles of water backed up behind ridges of ice—hence their name. While a little standing water might not seem like much of an issue, when your roof can’t shed it, it can worm its way under your shingles and reach your attic, causing everything from damp insulation to rotting roof structures.

There are a variety of ways that ice dams can form, and thus a variety of ways that you can act preventatively. Adequate roofing ventilation can help regulate your roofing’s temperature so that it stays cold, for example, which thus prevents ice dams from forming.

Wet Insulation

Your home depends on its insulation to stay warm through the winter, but that insulation can’t do its job if it’s all soggy! Excessive frost in the attic or leaks from ice dams can cause this problem, which can leave you with sky-high energy bills and a chilly house to boot. The best way to handle this moisture-related menace is to have a roofing company take a look at your insulation/ventilation ratio as a preventative measure, as an imbalance can cause condensation. You’ll also need to monitor your home for ice dams and quickly pursue the necessary roof repair should you find them.


Yes, mold! If your insulation is wet, your roof is poorly aerated, or ice dams have had their way with it, this issue could very well rear its ugly head. Luckily, preventing mold growth in the attic is generally as simple as preventing both of the other problems we talked about, as it cannot grow without moisture, though regular roofing inspections from a roofing contractor can spot problem areas before they snowball into something worse.
