New Jersey winters bring freezing rain, snow, and wind gusts up to 60 mph. Is your roof ready to handle it?
In this guide, we’ll walk you through exactly how to winterize your roof before the first frost—and why early prep can save you thousands in emergency repairs.
Step 1: Schedule a Professional Roof Inspection
The best time to inspect your roof is early fall—before temperatures drop and snow covers existing issues.
At T.A. Hughes, our certified team checks for:
-
Damaged or missing shingles
-
Rusted or loose flashing around chimneys and vents
-
Gutter blockages
-
Attic ventilation or insulation problems

Step 2: Clean Your Gutters and Downspouts
Clogged gutters are one of the top causes of ice dam formation, which leads to interior leaks and soffit damage.
-
Remove leaves, twigs, and roof granules.
-
Make sure downspouts are clear and diverting water at least 6 feet from the foundation.
-
In tree-heavy areas like Gloucester and Camden counties, consider gutter guards.

Step 3: Check Flashing, Vents & Roof Seals
Roof flashing is a thin metal installed to direct water away from critical areas like chimneys, walls, and valleys.
In winter, even a 1-inch gap can allow water to seep under the shingles and freeze, expanding cracks.
Signs you may need flashing repairs:
-
Rust or discoloration
-
Lifting or bent edges
-
Water stains in your attic or ceiling

Step 4: Evaluate Attic Ventilation & Insulation
Your attic is your roof’s silent partner. If it’s too warm in winter, it melts snow on the roof—leading to refreezing at the eaves and ice dams.
Key elements to review:
-
Minimum R-38 insulation level (as per NJ State Energy Code)
-
Clear soffit and ridge vents
-
No signs of condensation, frost, or mold
Upgrade attic insulation and ventilation during your inspection to reduce energy bills and extend roof lifespan.
Step 5: Replace Damaged or Missing Shingles
Minor shingle damage becomes a major issue in winter when snow and ice get beneath the surface.
Common signs to replace shingles:
-
Curling edges
-
Bald patches (missing granules)
-
Cracks or breaks
We use GAF and Owens Corning-certified materials, ensuring your home is protected with the industry’s best.

Step 6: Trim Overhanging Trees
In Burlington and Camden counties, heavy snow often leads to tree limbs falling on roofs, causing punctures or broken gutters.
Trim any branches within 8–10 feet of your roofline before winter hits.
If trees are large or close to power lines, hire a professional tree removal service.
Step 7: Consider Ice & Water Shield Installation
An ice & water barrier is a self-sealing underlayment applied beneath shingles in vulnerable zones like eaves, valleys, and low slopes.
-
Helps block moisture intrusion from wind-driven rain and ice damming
-
Especially valuable in older NJ homes lacking modern code-compliant protection

Frequently Asked Questions (FAQ)
When should I winterize my roof in New Jersey?
Ideally by late October or early November—before consistent overnight freezes begin.
Do I need to clear snow off my roof?
Only if accumulation exceeds 6 inches or your home has a low-slope roof. Use a roof rake from the ground, never climb up.
Can I install flashing or insulation myself?
Some tasks are safe for DIY, but roof work is best left to licensed professionals due to height and structural risks.
