Winter brings cozy nights by the fire, but for your home’s exterior, it brings a serious battle against the elements. At JM Roofing and Siding, we often see homeowners underestimate the impact that accumulated winter weather can have on their roof’s integrity until a leak appears in the spring.

Understanding the specific threats posed by snow and ice is the first step in protecting your investment. Here is how frozen precipitation can wreak havoc on your roofing system.

The Weight of Heavy Snowfall

Snow looks fluffy, but it is deceptively heavy. Fresh snow can weigh around 20 pounds per cubic foot, while wet, packed snow can be much heavier. Your roof is designed to handle a certain load, but an excessive accumulation can cause significant structural stress.

When snow piles up, it puts pressure on your rafters and trusses. In older homes or those with pre-existing structural issues, this can lead to bowing, cracking, or in extreme cases, roof collapse. Listening for strange creaking sounds during a storm is a good way to monitor stress levels.

The Menace of Ice Dams

Ice dams are perhaps the most common winter roofing issue. They form when heat escapes your attic and melts the snow on your roof. This water runs down to the colder eaves and refreezes, creating a ridge of ice.

This ridge traps subsequent melting water, preventing it from draining off the roof. The backed-up water can seep under shingles and into your home, damaging insulation, ceilings, and walls. Proper attic insulation and ventilation are your best defenses against this cycle.

Freeze-Thaw Cycles and Water Infiltration

Winter weather fluctuates. Water from melted snow can settle into tiny cracks in your shingles or flashing. When temperatures drop again, that water freezes and expands, widening the cracks. Over time, this freeze-thaw cycle compromises the waterproof barrier of your roof, leading to slow leaks that might not be visible until significant rot has occurred.
