Many homeowners face ice dams in cold climates, especially when their attics lack proper insulation or airflow
This occurs as warmth from inside your home causes snow to melt on the upper roof, only to freeze again at the overhangs, forming a dam
This trapped water can seep beneath shingles and infiltrate your home, damaging ceilings, walls, and insulation
Addressing the underlying thermal and ventilation issues is the only lasting solution
Adding more insulation helps maintain a cold roof surface, preventing the melt-freeze cycle
Proper airflow keeps the entire roof deck cold and uniform, reducing the risk of snow melting and refreezing
Seal these openings with high-quality caulk, expanding foam, or weatherstripping to block warm air from escaping
This reduces frost buildup that can later contribute to ice dam growth
This limits the snowpack available to melt and refreeze at the eaves
Your safety is more important than saving a few dollars on labor
If an ice dam has already formed, never use hammers, chisels, or sharp tools to break it apart
Calcium chloride is safe for Mundell Roofing Albion Park materials and effective at low temperatures
Stick to products specifically labeled for roof use
They work best when installed before winter and paired with proper insulation
Keep in mind that heat cables are a supplemental solution—not a replacement for insulation and ventilation
Clear leaves, debris, and ice buildup to ensure proper drainage
Taking these steps consistently will safeguard your home from expensive water damage and keep your family secure during freezing weather
