Signs it's time to replace

Most asphalt roofs in New Jersey last 20–25 years. If yours is near that age or showing the signs below, a replacement usually costs less over time than repeated repairs.

  • Curling, cracked or missing shingles
  • Granules collecting in gutters
  • Recurring leaks or attic stains
  • Sagging decking or soft spots
  • Daylight visible through attic boards

02

What every replacement includes

We quote the full system up front so there are no surprise add-ons once the old roof is off.

  • Complete tear-off and deck inspection
  • Ice & water shield at eaves and valleys
  • Synthetic underlayment
  • Ridge and soffit ventilation
  • GAF lifetime architectural shingles
  • Full cleanup with magnetic nail sweep

03

Warranty & financing

As a GAF Certified Plus contractor we can offer enhanced GAF system warranties, and flexible financing options are available so a new roof fits your budget.

“The Hammer Exteriors team was wonderful to work with! We had 3 exterior doors put in — 2 glass storm doors and 1 fiberglass front door. Rob was excellent at communicating with us each step of the way to ensure ordering, delivery and install all went smoothly. Even when they encountered something unexpected during the install, they handled the situation promptly and efficiently, and our project was not delayed. We would definitely use Hammer Exteriors again for our next home improvement project!”

“Our skylight started leaking after 5pm on Tuesday evening, I reached out to Rob Kurzner of Hammer Exteriors and within moments he was already figuring out when to come out to assess the damage and repair it. By the following Wednesday my skylights were replaced and the other problem areas of my roof were fixed. Highly recommend Rob and his team for their promptness and professionalism.”

“Replaced nine windows throughout the house. Our heating bill dropped noticeably and the house is so much quieter. The team was courteous and cleaned up every single day.”

“After a bad windstorm Rob came out the same day, tarped the roof, and helped us document everything for insurance. That kind of responsiveness is rare — genuinely grateful.”

“Honest advice is why I'll keep calling Hammer Exteriors. They told me a repair would hold instead of upselling a whole new roof. Two years later, still bone dry.”

“Siding, trim, and gutters all done together. Detail work around the dormers was flawless. The GAF Certified Plus designation isn't just a badge with these guys — the quality shows.”
