Ice damming is a common winter roofing problem in cold climates, caused when snow melts on a warm part of the roof and refreezes at the eaves, creating a ridge of ice. This ice blocks melting snow from draining properly, which can lead to leaks, water damage, and shingle deterioration. The right roofing shingles can significantly reduce the risk of ice dams while improving overall winter performance.
Why Ice Damming Happens
Ice damming occurs due to uneven roof surface temperatures. Warm spots on the roof cause snow to melt, and when the water reaches the colder eaves, it freezes again. This can be caused by:
Poor attic insulation
Inadequate ventilation
Heat loss from the home
Incorrect roofing materials
Choosing Roofing Shingles to Minimize Ice Dams
1. Architectural Roofing Shingles
Architectural shingles, such as Dynasty Roofing Shingles, provide a thicker, more layered design that improves insulation. Their weight and durability make them less prone to lifting, which can help maintain a consistent temperature across the roof.
2. Premium Designer Shingles with Enhanced Grip
Options like Armourshake Roofing Shingles not only add aesthetic appeal but also have built-in features for extreme weather resistance, helping to keep the roof surface temperature stable during winter.
3. Shingles with Ice and Water Shield Underlayment
Pairing your chosen shingles with an underlayment system—available through Scaffs India’s Accessory Products—provides an additional waterproof barrier. This prevents meltwater from penetrating beneath the shingles if ice does form.
4. Asphalt Shingles for Cost-Effective Ice Dam Protection
Traditional 3-Tab Asphalt Roofing Shingles can be an affordable solution when paired with proper ventilation and insulation upgrades.
Installation Practices That Help
Even the best shingles need correct installation for effective ice dam prevention. Recommended practices include:
Installing ridge vents and soffit vents for better airflow
Using self-adhesive ice barrier membranes along eaves and valleys
Ensuring correct shingle overlap to minimize gaps
