Prevent Ice Dams Before First Heavy Winter Snow

Cost Savings

Checklist Tasks

• Clear gutters and downspouts to ensure meltwater drains properly.
• Install heated gutter cables at eaves and downspouts before snowfall.
• Seal attic air leaks at fixtures and hatches to limit warm air escape.
• Add insulation baffles at eaves for clear airflow and less ice dam risk.
• Repair any damaged or missing shingles to guard against water entry.
• Check attic insulation depth for code compliance to cut heat loss.
• Weatherstrip attic doors to block warm air leakage into the attic.
• Trim overhanging branches to reduce roof debris and snow traps.
• Ensure soffit vents are clear to maintain attic-to-roof airflow.
• Seal chimney flashing and vent pipe gaps to prevent heat leaks.
• Test attic fans or ridge vents to keep attic close to outdoor temps.
• Avoid piling shoveled snow on roof edges to lessen ice dam risk.
