Roof problems in the winter are far from a rarity, but there are some cold weather roofing issues you might not expect.
Although they’re never pleasant to deal with, roof problems in the winter can be much worse than those encountered during other seasons. Between strong wintry winds that raise shingles and blizzard precipitation that forces its way into gaps and spaces, the colder months of the year tend to bring with them a lot of cause for homeowner headache.
Of course, not all winter roof issues are predictable. Some will be much less typical, and therefore easier to miss — informing yourself is crucial, as winter roof damage can lead to structural issues and significant extra expenses due to repairs.
Ice Dams are a Noteworthy Winter Roof Concern
If you’re unfamiliar with ice dams (as many people are), they are what can result from having warm air rise through your roof from your living spaces. A well-ventilated roof will keep this from happening, but the process for ice dam formation is as follows:
As the indoor heat warms up your roof shingles, the snow sitting on top of them melts. As it melts, it travels to the edges of the rooftop, where conditions are colder. The water then freezes. Once this newly formed ice grows thick enough, melting snow caught behind it will begin to seep underneath the shingles and find its way inside.
Winter Roofs Contend with Snow Weight
Even if we see large mounds of snow atop a rooftop, we often don’t consider it an actual problem. Roofs can withstand the elements, so some snow accumulation isn’t anything to worry about, right? Wrong!
Rooftops can vary, not just in size and design but also when it comes to the loads they can accommodate. Ice and wet snow can exert huge amounts of pressure on a roof, especially if the roof construction is questionable. A rooftop overburdened by wintertime precipitation can develop leaks, persistent creaking sounds, and even a sagging ceiling. A roof collapse is also a possibility.
Wintertime Attic Moisture
If your rooftop has snow or ice build-up, your attic may have a problem with condensation. Poor ventilation, as well as ice dams, can contribute to this issue. Even in small amounts, accumulated moisture translates to mold growth and rotting wood. This can be costly, for more than one reason — mold and mildew can lead to harmful air particles in your home, which can cause breathing issues over time. Additionally, moisture that builds up behind the walls can cause notable structural damage as wooden beams and supports decay.
