5 Issues Leading to Roof Leaks in Winter

As winter blankets our homes with layers of snow in the Tri-State area, that also leads to challenges for our roofs. Winter roof leaks can disrupt the cozy tranquility inside, posing a threat to our homes’ structural integrity. 

In this exploration, we delve into the intricacies of the top five reasons behind roof leaks during winter.

1. Ice Dams

Ice dams form when melting snow refreezes at the roof’s edge, creating a barrier that prevents proper drainage. This standing water can find its way beneath shingles, causing leaks into your home.

2. Condensation Buildup 

Temperature differentials between your warm home and the cold exterior can lead to condensation. When warm indoor air meets a cold roof surface, moisture accumulates and can eventually penetrate the roof structure. 

3. Flashing Failures 

The metal strips, or flashing, around chimneys, vents, and skylights are vulnerable points. Winter’s harsh conditions, including freezing and thawing, can compromise the flashing’s integrity, allowing water to infiltrate. 

4. Snow Accumulation

A heavy snow load on your roof can exceed its weight-bearing capacity. The excess weight not only stresses the structure but can also lead to development of ice dams and subsequent leaks. 

5. Cracked or Damaged Roofing Materials 

Extreme temperature fluctuations in winter can cause roofing materials to contract and expand, leading to cracks or damage. These compromised areas become entry points for water, resulting in leaks. 

In closing, winter’s subtle threats to our roofs demand awareness and proactive care. Understanding the causes of roof leaks empowers homeowners to fortify their homes against potential water intrusion.
