February's freeze-thaw cycle is the perfect recipe for ice dams—one of winter's sneakiest and most damaging home problems. When heat from your attic melts roof snow, that water refreezes at the cold edge, creating an ice barrier that traps water under your shingles. The result? Leaks, water damage, and potential mould.

❄️ Warning Signs

✔ Large icicles along your roofline

✔ Water stains on ceilings or walls

✔ Ice-packed gutters

✔ Sagging gutters

🛡️ Prevention Tips

✔ Improve attic insulation. Keep heat inside where it belongs.

✔ Ensure proper ventilation. Good airflow keeps your roof cold and prevents uneven melting.

✔ Keep gutters clean. Clear gutters allow water to drain properly.

✔ Use a roof rake safely. After heavy snow, gently remove snow from the lower few feet of your roof.

🚨 If You Already Have Ice Dams

✔ Don't chip at the ice. You'll damage your roof.

✔ Use calcium chloride. Fill a nylon stocking with it and lay it across the dam to melt a drainage channel.

✔ Call a professional for severe dams or interior water damage.

✔ Check your attic for wet insulation or water intrusion.

💙 Stay Ahead of the Problem

February's unpredictable weather doesn't have to mean home damage. A little prevention now saves thousands in repairs later. Keep your roof clear, your attic well-insulated, and your gutters flowing freely.

Stay warm and dry, Waterloo Region!
