How Long Does a Roof Last in New Jersey?

New Jersey’s climate puts serious stress on roofing systems. Freezing winters, coastal humidity, and high summer temperatures all shorten the lifespan of most roofs compared to other states.

Asphalt Shingle Roof Lifespan

• 3-tab shingles: 12–17 years
• Architectural shingles: 20–28 years
• Premium shingles: 28–35 years

Metal Roofing Lifespan

Metal roofs can last 40–70 years, making them one of the most durable options for New Jersey homes.

Flat Roofing Lifespan (EPDM, TPO, Modified)

Most flat roofs in New Jersey last 15–25 years, depending on the material and how well they are maintained.

Factors That Reduce Roof Lifespan

• Poor attic ventilation
• Storm damage and high winds
• Clogged gutters and standing water
• Improper installation or cheap materials

Signs Your Roof Is Near the End

• Curling or cracked shingles
• Missing granules in gutters and downspouts
• Frequent interior leaks or ceiling stains
• Sagging rooflines or soft decking

How to Extend Your Roof’s Lifespan

• Schedule annual roof inspections
• Keep gutters and downspouts clean
• Replace failing flashing early
• Improve attic airflow and insulation
• Fix small leaks before they spread
