During a long winter, snow can add some wonderland-like charm to an otherwise dreary landscape. However, this form of precipitation is not as friendly to your roof. Heavy snowfall can damage your home’s exterior, even requiring the need for a roof replacement. To learn more about why you need to protect your house from winter weather, consider the following list.

3 Ways in Which Snow Affects Roofs

1. Dark Spots

After piling up on your roof, the winter snow will slowly melt, forming puddles that freeze, thaw, and re-freeze as the temperature fluctuates. If the water isn’t removed, it could soak into your roofing materials, leaving dark spots where absorption is heaviest. If you see these discolored areas on your roof, there’s a significant chance you need a roof replacement for water damage.

2. Shingle Damage

If you have an asphalt, slate, or shake roof, water damage could cause your shingles to buckle or curl in response to both the extreme temperature exposure and the moisture absorption. In some cases, they may become so weak that they fall right off your home’s exterior. If the damage covers a large part of the roofing, you’ll likely need a roof replacement.

3. Attic Condensation

During the winter, central heat will make your living spaces comfortable. However, since hot air rises, the treated air will drift up out of your living and sleeping areas and into your attic. If snow is sitting on top of your roof, the temperature variation between the freezing exterior and toasty interior will cause condensation to form in your attic. This could ultimately lead to interior water damage, as well as mold growth and other consequences.
