New Jersey winters can be tough on a roof. Nor’easter winds and heavy, wet snow are common, as well as constant cycles of freeze-thaw. Preparation in the fall will help prevent leaks, ice-dams and emergencies mid-January. This is a guide that will help you with winter roofing in NJ.
1) Begin with a thorough inspection from top to bottom
Look up as you walk around your property. Check the attic.
- Shingles: Check for cracks, curling, missing tabs or exposed nails.
- Flashing: Check around skylights and chimneys for rust or gaps.
- Sealants: Replace any caulk that has dried or cracked around penetrations.
- Check the attic in daylight. Look for water stains or dark streaks. Moisture may be present if you can smell musty air.

Remove gutters and downspouts
Ice dams can be caused by clogged gutters. Remove leaves, sediment and granules. Make sure you:
- Downspouts should discharge at least 4 to 6 feet away from the foundation.
- Hangers and spikes must be tight to prevent gutters from sagging under the ice load.
- If trees are overhanging the roof, consider gutter guards. However, inspect your home after storms.
Balance ventilation and insulation
Ice dams are formed when heat escapes from the attic and warms the roof deck. This melts snow at the eaves, which then refreezes.
- Insulation: Increase attic floor insulation in order to reduce heat loss. Most NJ homes benefit from a higher R value than the older standards.
- Sealing gaps around can lights, plumbing stacks and attic hatches will stop warm air leaking.
- Ventilation: Pair intakes on the soffit with vents in the ridge so that cold air enters low and leaves high. Soffit vents should be cleaned of debris and insulation. A good airflow will keep the roof deck dry and cold.
Trim the trees and protect your roof edge
Snow-loaded branches can break and fall. Trim branches 8-10 feet from the roof. Consider installing snow guards on metal sections that are inclined to slide. This will slow down the sliding and protect your gutters.
5) Fortify vulnerable details
- Chimneys – Check crowns and mortar. Install a cap on the chimney to keep water and animals out.
- Skylights: Check that weepholes are open and gaskets are intact.
- Valleys: This area is the most prone to runoff. Now is the time to replace worn or torn metal shingles.
6) Prepare for snow and ice removal
Prevention is the best strategy, but you should also be prepared.
- Tools: Use a snow rake that is roof safe and has a non-conductive, long handle.
- Technique: After a big storm, remove the top few inches of snow from near the eaves to prevent dam formation.
- Use calcium chloride roof products if necessary. Avoid using rock salt to treat shingles.
- Cables: Heat cable can be used to help chronic dam areas. However, you must first improve the insulation and ventilation.
7) Be aware of the coastal factor
Winter brings salt spray and wind-driven rain along the shore. Replace missing shingle nail with galvanized or stainless fasteners, if necessary. To prevent uplift, ensure that starter strips and adhesive strip are well-bonded at eaves.
Create a Winter Roof Kit
Stock up on these items in advance of the first storm.
- Safety glasses, gloves and roof rake
- De-icer for roofs and walkways that melts ice
- Towels, flashlight, contractor bags and plastic sheeting are quick interior protection measures.
- Your home insurance information and a list of emergency contacts
Document and schedule maintenance
Take pictures of your roof, gutters and attic during the fall. You’ll be able to compare and claim damage if a storm occurs. You can set reminders for a mid-winter check after the first big snowfall, a late fall check and a follow-up in the spring.
10) When to call in a professional
Do not climb on the roof in winter if you notice widespread shingle losses, sagging rain gutters, a soft decking or active leaks. Have a professional inspect the roof. You’ll be safer and get a repair plan that prioritizes.
Bottom Line
The most important thing to do when preparing your roof for an icy winter in New Jersey is to control the temperature and water. Seal heat leaks and ventilate your attic. Pay attention to the small details. If you do the easy work now, it will be easier to face the winter with less stress, fewer costs and a roof ready for the weather.
