​

If you own a home in South Jersey long enough, you’re going to deal with roof replacement.

 

It’s not exciting. It’s not glamorous. But it’s one of the most important investments you’ll make in your home.

 

Most homeowners start with the same questions:

• How do I know if I actually need a new roof?

• How much is this going to cost?

• Can I just repair it?

• How long will it last?

• Who can I trust to do it right?

 

This guide walks you through all of it — clearly and honestly — so you can make a confident decision.

 

We serve homeowners throughout Haddonfield, Marlton, Cherry Hill, and surrounding Camden County communities, and these are the conversations we have every day.

​

​

When Do You Actually Need a Roof Replacement?

 

Not every roofing issue means full replacement.

​

But there’s a point where repairs stop making financial sense.

​

Here are the most common signs it’s time:

​

1. Your Roof Is 20+ Years Old

Most asphalt shingle roofs in New Jersey last 20–30 years depending on ventilation, installation quality, and storm exposure.

 

If you're unsure what that really means for your home, read our breakdown on how long a roof lasts in NJ.

​

Age alone doesn’t always require replacement — but it’s a strong indicator.

​

2. Shingles Are Curling or Buckling

This usually means the shingles are drying out and losing flexibility. Once that starts happening across large sections, repairs won’t fix the underlying deterioration.

​

3. Granules Are Filling Your Gutters

If you’re seeing heavy granule loss, your shingles are nearing the end of their protective life.

​

4. Multiple Leaks

One leak can be repairable.

​

Two or three leaks in different areas? That’s usually system failure.

Roof Repair vs. Roof Replacement: How to Decide

 

This is the real decision most homeowners struggle with.

 

Here’s the simple way we explain it:

​

Repair Makes Sense When:

• Roof is under 15 years old

• Damage is isolated

• Decking underneath is solid

• No widespread deterioration

​

Replacement Makes Sense When:

• Roof is 20+ years old

• You’ve had repeated repairs

• Multiple sections are failing

• You’re preparing to sell

• Storm damage impacted large areas

​

In South Jersey, waiting too long can lead to interior water damage, mold, and structural issues.

 

Sometimes replacing earlier actually saves money long term.

​

​​

How Much Does Roof Replacement Cost in South Jersey?

 

This is the second most asked question.

 

For a detailed breakdown, read our guide on new roof cost in NJ.

 

But here are realistic ranges for our area:

​

Asphalt Shingle Roof Replacement

 

Most standard homes:
$8,500 – $16,000

 

Larger homes, steep pitches, wood decking or complex roof lines can exceed that.

​

The real cost depends on:

• Roof size (measured in squares)

• Pitch (steepness)

• Tear-off vs overlay

• Decking condition

• Flashing complexity

• Ventilation upgrades

​

Be cautious of extremely low bids. They often involve shortcuts like layering over old shingles, reusing old flashing or not replacing bad wood.

​

You won’t see the problem immediately — but you will.

​

The Roof Replacement Process (What Actually Happens)

 

Homeowners often picture chaos.

​

Here’s what really happens when done properly.

​

Step 1: Full Inspection

 

We evaluate:

• Shingles

• Flashing

• Ventilation

• Decking condition

• Chimney and penetrations

​

If chimney flashing is compromised, we coordinate with our chimney repair man(John) to address it properly.

​

Step 2: Tear-Off

We remove existing roofing materials down to the decking.

​

We do not recommend overlaying new shingles over old ones. It hides damage and reduces lifespan.

​

Step 3: Decking Inspection

 

Once exposed, we check for soft or rotted plywood and replace as needed.

​

This is critical. Skipping this step causes future failure.

​

Step 4: Underlayment & Ice Shield

 

We install high-quality underlayment and ice barrier protection, especially important in NJ’s freeze-thaw cycles.

​

Step 5: Flashing Installation

 

New flashing is installed around:

• Chimneys

• Valleys

• Skylights

• Roof penetrations

​

Flashing failure is one of the most common causes of leaks.

​

Step 6: Ventilation Upgrades

 

Proper attic ventilation extends roof lifespan significantly.

​

Poor ventilation causes:

• Heat buildup

• Moisture accumulation

• Premature shingle failure

​

We evaluate ridge vents, soffits, and intake/exhaust balance on every replacement.

​

Step 7: Cleanup

 

We magnet roll for nails, remove debris, and leave the property cleaner than before.

​

A professional roofing job should will never look like a construction zone when we leave.

​​

​

How Long Does Roof Replacement Take?

 

Most standard homes:

1–2 days

​

Larger or more complex homes may take 3–4 days.

​

Weather can extend timelines, but we plan carefully to minimize exposure.

Homeowners can usually remain in the home during installation.

​​

​

Insurance & Storm Damage

 

Storms in South Jersey can cause:

• Wind uplift

• Missing shingles

• Flashing damage

• Tree impact

​

Insurance may cover storm-related damage but does not cover normal wear and tear.

​

We help document storm damage properly if needed.

​

If you suspect recent storm impact, start with an evaluation through our roof repair services before assuming full replacement.

​​

​

Why Ventilation Matters More Than Most People Realize

 

Many roofing problems aren’t shingle problems.

 

They’re ventilation problems.

 

Improper airflow leads to:

• Ice dams

• Mold growth

• Warped decking

• Shortened shingle lifespan

• Higher energy bills

​

A roof is a system — not just shingles.

 

Upgrading ventilation during replacement often adds years to the roof’s life.

​​

​

Preparing to Sell? A New Roof Can Increase Value

 

If you’re listing your home in Cherry Hill or Haddonfield, buyers notice roofs immediately.

 

A new roof can:

• Increase buyer confidence

• Reduce negotiation pressure

• Improve inspection results

• Speed up closing

​

An aging roof often becomes a bargaining tool for buyers.
