Common Causes of Roof Damage in NJ

1. Storms & High Winds

New Jersey sees strong storms, Nor’easters, and heavy winds that can rip shingles loose or damage flashing.

2. Winter Damage

Snow and freezing weather can cause ice dams, which force water under shingles and create leaks.

3. Aging Roofs

Older shingles lose granules, curl, or crack, making the roof vulnerable to leaks.

4. Poor Installation

Improper nail patterns, missing underlayment, or bad flashing cause 70%+ of roof problems.

5. Trees & Debris

Overhanging branches scrape shingles or fall during storms.

How to Know if You Need a Roof Repair

You may need a repair if you notice:

Water stains on ceilings
Missing or cracked shingles
Loose or rusted flashing
Granules in gutters
Mold or dark streaks
Soft spots on the roof
If the leak is active, call a roofer immediately — water damage spreads fast.

When Is Repair Better Than Replacement?

Choose repair if:

Your roof is under 15 years old
The damage is localized
The decking is still solid
The cost of repair is less than 25% of replacement cost
Choose replacement if:
The roof is 20+ years old
You see leaks in multiple areas
Shingles are curling or losing granules everywhere
The repair cost is approaching half of a new roof
