How Winter Precipitation Affects Your Roof

Jan 15, 2021Roofing

One of the busiest times for roof repair professionals is the winter season. This is when roofs – particularly those that have not received regular maintenance – typically give in to the punishment of the freeze-thaw cycle.

Winter is a time of plenty of precipitation: rain, snow and, sometimes, hail and ice. As moisture is known for causing damage to roofs and other exterior home surfaces and components, your home should be prepared during this time.

How Winter Damages Your Roof

Snowstorms can force moisture to enter your home if your roof is missing some shingles or has damaged flashing or no drip edge. There are also many other ways a roof can be compromised. Snow can accumulate on your residential roofing system and add plenty of weight. It doesn’t fall on your roof evenly, either. Some parts can have four to five times as much snow due to how snow blows. In most cases, those areas are also the most vulnerable to moisture penetration and damage.

How Expanding Water Can Cause Damage

When rain or sleet falls on your roof, moisture can find its way into the tiniest cracks and gaps. If the temperature drops after the rainfall, the water stuck in those tiny crevices will freeze. As water freezes, it expands, so those tiny cracks will soon be forced to expand as well. If there are frequent freeze-thaw cycles, it’s tougher for roofing materials and other components of your home to stay intact.

What to Do

You can’t control the weather. The freeze-thaw cycle will happen whether you’re ready or not. But what you can do is keep your roof in good condition by maintaining it throughout the year. Regular upkeep – plus good workmanship and high-quality materials (such as a GAF Roof) – can extend the life of your roofing system even if your area is prone to harsh winters.
