Asphalt shingles are a popular and reliable roofing material for homes across New Jersey. They're affordable, weather-resistant, and come in a variety of styles. But like any part of your home, they don’t last forever. After years of battling NJ’s harsh winters, high winds, summer heat, and heavy rain, your shingles can start to wear out often without you realizing it.

So how can you tell when it’s time to replace your asphalt shingles?

At Cephalo Roofing, we’ve helped homeowners across New Jersey identify roofing issues early and replace aging shingles before serious damage occurs. Here are the 10 most common signs your roof needs attention and what to do next.

1. Your Roof is Over 20 Years Old

Most traditional asphalt shingle roofs last about 20–25 years, depending on maintenance, weather exposure, and the quality of installation. If your roof is reaching that age even if it looks okay it’s smart to start planning a replacement.

Architectural or laminated shingles may last up to 30–50 years, but regular inspections are still important after the 20-year mark.

Tip: Not sure how old your roof is? Check with your township for roofing permits or contact Cephalo Roofing for a full roof assessment.

2. Curling or Buckling Shingles

Curling edges or buckled centers on shingles are common signs of aging or poor attic ventilation. They also make your roof more vulnerable to:

Wind damage
Water infiltration
Shingle blow-offs

These deformed shingles can't protect your home properly and should be replaced promptly.

3. Missing or Broken Shingles

New Jersey storms can take a toll on your shingles. If you see bare patches or find shingles on your lawn, your roof may be exposed.

You can replace individual shingles, but if it becomes a pattern, a full shingle roof replacement might be the more cost-effective, long-term solution.

4. Granules in Your Gutters

Shingle granules protect your roof from the sun and weather. Over time, especially in older roofs, granules begin to shed and accumulate in your gutters.

Signs of excessive granule loss include:

Bald spots on shingles
Dark, sand-like buildup near downspouts
Fading or uneven color across your roof

This indicates your shingles are breaking down and need to be evaluated.

5. Faded or Patchy Roof Appearance

A roof that looks worn, streaked, or blotchy might be more than just an eyesore. Common causes include:

Algae or moss growth
UV damage
Granule loss
Trapped moisture

If your roof’s color looks uneven or streaked, it may be nearing the end of its lifespan.

6. Water Leaks or Stains

If you’re seeing:

Water spots on ceilings
Damp insulation in the attic
Mold or mildew growth

…it’s a major red flag.

Roof leaks often start small and go unnoticed until they cause visible interior damage. In many cases, deteriorated shingles or failing flashing are to blame.

7. Ice Dams in the Winter

Ice dams are a common winter roofing problem in New Jersey. They form when snow melts on a warm section of the roof and refreezes at the edges.

This causes:

Water backup under shingles
Roof deck damage
Gutter strain or detachment

Ice dams often point to poor attic insulation or aging roofing materials both good reasons to consider a replacement.

8. Cracked or Blistered Shingles

Cracks and surface blisters are caused by:

Prolonged sun exposure
Poor attic airflow
Temperature fluctuations

Cracked shingles lose their waterproof layer and can’t protect your roof. Widespread cracking often means it’s time to install new shingles.

9. Sagging or Uneven Rooflines

A sagging roofline is a serious issue and can indicate:

Structural problems in rafters or decking
Moisture damage
Rotted wood beneath shingles

Don’t ignore this. A sagging roof should be inspected immediately by a professional NJ roofing contractor.

10. Higher Energy Bills

Notice a spike in your heating or cooling bills? Your roof could be the cause.

Worn or poorly ventilated roofs trap heat in the summer and let out warm air in the winter. A new asphalt shingle roof with proper ventilation can help lower your energy costs and improve year-round comfort.

Bonus: You're Selling Your Home Soon

Thinking of listing your house? A worn-out roof can turn buyers away or result in lower offers. A new roof can:

Increase resale value
Boost curb appeal
Speed up your sale

It’s a worthwhile investment if you’re getting ready to put your home on the market.
