Winter can be especially harsh on your roof. Snow accumulation, freezing temperatures, and fluctuating weather conditions create the perfect environment for ice dams which is one of the leading causes of winter roof leaks. Many homeowners don’t realize they have an ice dam problem until water stains appear on ceilings or walls. Suburban / Larchmont Roofing will breakdown how ice dams form, how they lead to leaks, when to call for professional roof leak detection services and help you prevent costly damage and protect your home all winter long.
What are Ice Dams?
Ice dams form when snow on your roof melts due to heat escaping from the attic and then refreezes near the roof’s edge or gutters. Over time, this creates a ridge of ice that blocks proper drainage. As more snow melts, water becomes trapped behind the ice dam and has nowhere to go so it backs up under shingles and into your home.
How Ice Dams Cause Roof Leaks
Ice dams are particularly dangerous because they force water to move in the opposite direction of normal drainage. Here is how they lead to leaks:
• Water Backs Up Under Shingles: Shingles are designed to shed water downward not resist standing water. When meltwater pools behind an ice dam, it can seep beneath shingles and into the underlayment and roof deck.
• Underlayment and Decking Become Saturated: Once moisture penetrates these layers, it can cause wood rot, weakened decking, and interior leaks.
• Flashing and Sealant Are Compromised: Ice expansion can loosen flashing around chimneys, vents, and skylights, creating additional entry points for water.
• Interior Damage Develops: Water eventually finds its way into attics, ceilings, walls, and insulation leading to stains, mold growth, and structural damage.
When to Get Roof Leak Detection Services
You should schedule roof leak detection services if you notice any interior water stains or dripping, icicles or ice buildup forming along roof edges. If your home has a history of ice dam problems, you experience a sudden increase in humidity or musty smells, a winter storm has recently passed and your roof is older or nearing the end of its lifespan you need leak detection services. Waiting until spring can allow damage to worsen, increasing repair costs significantly.
How Professionals Address Ice Dam-Related Leaks
Once leaks are detected, roof professionals may:
• Repair or replace damaged shingles and underlayment
• Replace compromised flashing
• Repair roof decking if necessary
• Improve attic insulation and ventilation
• Install ice and water shield barriers
• Recommend snow and ice dam prevention solutions
These steps address both the immediate leak and the underlying cause.
