Preparing Your NJ Roof for Winter: A Seasonal Checklist

The Fall Roof Prep Checklist

1. Clean Gutters and Downspouts

Task #1. Clogged gutters = ice dams = interior water damage. Wait until late November when most leaves have fallen. Direct downspouts 4+ feet from foundation.

2. Inspect Flashing and Sealant

Check around chimneys, skylights, vent pipes. Cracked caulking or lifted flashing costs $100-$300 to fix now vs thousands later.

3. Look for Missing Shingles

Use binoculars from the ground. Any gaps should be repaired before winter — an open invitation for ice and water.

4. Trim Overhanging Branches

Heavy snow causes breakage. Trim back at least 6 feet. Hire an arborist for tall trees.

5. Check Attic Insulation and Ventilation

Your primary ice dam defense. Check insulation depth (should be 12-16 inches), ensure soffit vents aren't blocked, verify ridge vents are clear.

6. Fix Existing Leaks

Water that freezes expands 9%, widening every gap. A small October leak becomes a much larger January leak.

What to Have on Hand

• Roof rake (telescoping, from the ground — never climb a snowy roof)
• Calcium chloride ice melt (NOT rock salt — damages shingles)
• Your roofer's emergency number
