Top 3 Roofing Mistakes NJ Homeowners Make (And How to Avoid Them)

20October 2025

Learn from South Jersey’s roofing experts how to prevent costly roof problems before they start.

Introduction: Why Roofing Mistakes in NJ Cost More Than You Think

In New Jersey, your roof faces some of the toughest conditions in the country — freezing winters, hot humid summers, and unpredictable nor’easters.

Yet most roof problems don’t come from bad weather — they come from avoidable mistakes homeowners make without realizing it.

At T.A. Hughes Roofing, we’ve repaired thousands of roofs across Burlington, Camden, and Gloucester Counties over the past 35+ years. And time and time again, we see the same preventable issues leading to major damage.

Here are the top 3 roofing mistakes NJ homeowners make — and how to avoid them.

Mistake #1: Waiting Until There’s a Leak to Schedule a Roof Inspection

The Problem

Many homeowners wait until water stains appear on their ceiling before calling a roofer.
By that point, it’s not just a leak — it’s often rotted decking, mold, and insulation damage hiding behind the drywall.

NJ-Specific Issue

Our region’s freeze-thaw cycles make small cracks expand and contract all winter long. What starts as a tiny gap can become a full-blown leak by spring. Add in high winds from nor’easters and sudden downpours, and you’ve got a recipe for damage.

The Solution

Get ahead of problems with annual or seasonal roof inspections — especially after major storms.
A certified contractor will check for:

  • Cracked or lifted shingles

  • Rusted flashing or pipe boots

  • Poor attic ventilation

  • Hidden leaks or moisture damage

Pro Tip: A fall inspection before the first freeze can save thousands in emergency winter repairs.

Mistake #2: Choosing the Cheapest Roofing Estimate

The Problem

Everyone loves a good deal — but when it comes to roofing, cheap can get expensive fast.
Many homeowners go with the lowest bid, only to discover the contractor wasn’t licensed, insured, or using quality materials.

Low-cost jobs often skip critical components like:

  • Ice & water barriers

  • Underlayment

  • Ridge ventilation

  • Manufacturer-approved fasteners

Table: Cheap Contractor vs. Certified Roofer in NJ

Feature Low-Cost Contractor GAF-Certified Roofer
License & Insurance ❌ Often missing ✅ Always verified
Manufacturer Warranty ❌ Limited or none ✅ 25–50 year coverage
Installation Quality ❌ Inconsistent ✅ Trained & vetted crews
Permit Compliance ❌ Often skipped ✅ Fully compliant
Long-Term Costs 🚫 Higher due to repairs ✅ Lower over time

 

Real-World Example

We recently helped a homeowner in Swedesboro who hired a budget roofer after a storm. Within 2 years, the roof began leaking — the contractor had nailed shingles directly to the old layer without new underlayment. They ended up paying double to have it properly replaced.

The Solution

Always verify credentials before hiring:

  • Ask for NJ contractor licensing and insurance

  • Confirm they’re a GAF Certified Contractor

  • Request references or local job examples

  • Get all materials and warranty details in writing

Mistake #3: Ignoring Small Repairs That Lead to Major Damage

The Problem

It’s easy to overlook a missing shingle or small drip — especially if it doesn’t seem urgent.
But minor roof damage compounds fast under NJ’s volatile climate.

Small gaps invite:

  • Water intrusion during heavy rain

  • Ice dam formation in winter

  • Wind uplift that spreads shingle loss

  • Mold and wood rot inside attics

The Solution

Address minor issues as soon as you spot them. A $250 flashing repair now can prevent a $5,000 decking replacement later.

If you notice loose shingles, stains, or moisture in your attic — call a pro immediately.

Bonus Mistake: Skipping Fall Roof Prep Before Winter

Many homeowners assume their roof will “make it through one more season.”
But fall is the critical window to clean gutters, check flashing, and fix any weak points before snow and ice arrive.

Ice dams, blocked gutters, and freeze cracks are the #1 cause of winter roof emergencies in New Jersey.
