During winter, ice dams frequently develop in residences where heat escapes into the attic, causing uneven roof temperatures
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
Begin by upgrading your attic insulation to minimize heat loss into the roof cavity
Proper airflow keeps the entire roof deck cold and uniform, reducing the risk of snow melting and refreezing
Inspect areas like recessed lighting fixtures, chimneys, duct penetrations, and attic access panels for air leaks
This reduces frost buildup that can later contribute to ice dam growth
During heavy snowfall, use a roof rake to carefully remove snow from the bottom 3 to 4 feet of your roof
If the roof is difficult to access or dangerous, hire a trained professional to clear the snow
These methods can puncture shingles, damage flashing, and create costly leaks
Calcium chloride is safe for Mundell Roofing Albion Park materials and effective at low temperatures
Avoid using rock salt or sodium chloride—these corrosive substances can destroy shingles, rust gutters, and kill landscaping
They work best when installed before winter and paired with proper insulation
Always prioritize air sealing and insulation upgrades first
Promptly repair any signs of water stains, peeling paint, or damp insulation
A well-maintained home is a safe, dry, and energy-efficient home
