3 Risks To Your Roof During Winter

Do you live in an area of the country where temperatures can get pretty low during the winter months? Are snow and ice regular occurrences in your area? If so, you're likely familiar with much of the work and maintenance needed to protect your home from snow, ice, and other elements. You have to shovel your driveway after snow storms and make sure your sump pump is working to remove excess water. You may even need to salt your sidewalks and perhaps run a check on your furnace.

During your preparation for the winter, don't ignore your roof. Your roof is perhaps the most vulnerable component of your home to winter weather. After all, snow and ice accumulate on top of your roof. While you have gutters and downspouts to remove the moisture, snow and ice can still do serious damage. Below are three risks to your roof and how you can protect it:

Condensation. You likely run your furnace in the winter to keep your home warm. That warm air naturally rises through your home to your attic. If you don't have sufficient ventilation in your attic, the hot air could get trapped there. How does this affect your roof? The surface of your roof is cold in the winter. The combination of warm air with cold surface creates condensation that could sit on your roof and potentially freeze. It could even get under your shingles and warp or crack the wood. 

You can prevent this issue by checking the ventilation in your attic. Make sure the vents are clear and that air is properly escaping your home. A roofing expert can help with this.

Ice dams. An ice dam is another risk that is caused by insufficient ventilation. Ice on the top part of your roof often melts quickly due to sunshine and heat from inside the home. However, ice at the edge of the roof may not melt as fast. When this happens, the water running down your roof will hit remaining ice or snow and refreeze, forming a large dam or chunk of ice. This ice dam can damage your roof, gutters, and more.

Again, ventilation is key. Your home should have vents that transfer heat to the soffit, which is the part of your roof that overhangs the edge of your house. This helps the ice at that level melt and drain through the gutters. Check your ventilation to make sure warm air is reaching that area of your roof.

Icicles. Icicles may look pretty but they can do serious damage. They can drag down your gutters, perhaps separating them from the side of your roof. That can create a gap where water falls down to the foundation of your home. Icicles are usually caused by clogged gutters. Before it gets too cold out, check your gutters for leaves, sticks, and other debris. You want a clear passageway for moisture to drain away from your home.
