New Jersey winters bring snow, ice, freezing temperatures, and the dreaded ice dam. Preparing your roof before the cold sets in protects your home and helps you avoid emergency repairs during the worst weather. Here's your winter roof preparation checklist.

Inspect and Repair Before the Cold

Have your roof inspected in the fall and address any loose shingles, worn flashing, or minor damage before winter. Small problems become much worse — and harder to fix — once snow and ice arrive.

Clean Your Gutters

Clogged gutters are a leading cause of ice dams. Clear out leaves and debris so melting snow can drain properly instead of backing up and refreezing at the roof's edge.

Understand Ice Dams

Ice dams form when heat escaping through the roof melts snow, which refreezes at the cold eaves. The trapped water can back up under shingles and leak into your home. Proper insulation and ventilation are key to preventing them.

Improve Attic Insulation and Ventilation

A well-insulated, properly ventilated attic keeps your roof deck cold and uniform, which is the best defense against ice dams. It also lowers your heating bills.

Trim Trees Near the Roof

Heavy snow and ice can cause branches to break and fall on your roof. Trim back any branches that could pose a risk during winter storms.
