Understanding Ice Dams and Their Impact

Ice dams are a common wintertime problem for many homeowners, especially in areas with heavy snowfall. These ice formations occur at the edge of a roof and prevent melting snow from draining off. The water that backs up behind the dam can leak into a home and cause damage to walls, ceilings, insulation, and other areas.

Causes of Ice Dam Formation

The primary cause of ice dams is uneven roof surface temperatures. This happens when warm air in the attic heats the roof deck, melting the snow. The melted snow flows down the roof surface until it reaches the colder roof edge and refreezes, forming an ice dam.

Preventative Measures for Ice Dams

Attic Insulation and Ventilation: Proper insulation and ventilation in the attic are crucial in preventing ice dams. Insulation keeps the heat inside your home from reaching the roof, while ventilation removes the heat and keeps the roof temperature even.

Seal Attic Air Leaks: Sealing air leaks in the attic prevents warm, moist air from flowing into the attic space, thereby reducing the chance of ice dam formation.

Roof and Gutter Maintenance: Regular maintenance of roofs and gutters is essential.

Clearing your gutters and downspouts from leaves, sticks, and other debris helps ensure proper drainage of melting snow.

Ice Dam Removal Techniques

Heated Roof and Gutter De-icing Cables: Installing heated cables along the roof edge and in gutters creates a path for the meltwater to drain properly, preventing ice dam formation.

Roof Rakes: Using a roof rake to remove snow from the roof can prevent ice dams from forming. It’s important to do this carefully to avoid damaging the roof shingles.

Solutions for Existing Ice Dams

Calcium Chloride Ice Melter: Applying calcium chloride ice melter in a nylon stocking across the ice dam can help melt it without damaging your roof.

Professional Ice Dam Removal: For severe ice dam issues, it’s advisable to contact professionals like MaxForce Roofing and Siding LLC, based in Columbus, OH, who specialize in safe and effective ice dam removal.

Long-Term Solutions

Improving Roof Insulation and Ventilation: Upgrading attic insulation and ventilation is a long-term solution that can significantly reduce the likelihood of ice dam formation.

Installing a Water and Ice Shield: A water and ice shield is a membrane installed under the roof covering that provides an extra layer of protection against water penetration due to ice dams.
