Roof Replacement in South Brunswick, NJ

What Roof Replacement Involves

Roof replacement means removing your existing shingles, underlayment, and flashing down to the roof deck, then installing a brand-new system. This is different from repairs—we address structural issues like rotten decking, inadequate ventilation, and outdated ice-and-water shielding. In South Brunswick, we commonly see asphalt shingle granule loss from freeze-thaw cycles, ice dam formation causing water infiltration under shingles, flashing corrosion from salt spray and moisture, algae and moss growth in humid summer conditions, cracked or curling shingle edges, water stains on interior ceiling after rain, granules in gutters and downspouts, and missing or lifted shingles after wind storms.

Materials We Recommend for South Brunswick Homes

We primarily install asphalt architectural shingles with Class A fire rating—the standard for New Jersey residential code. Our top picks include dimensional shingles like GAF Timberline HD and Owens Corning Duration, which offer 30-year warranties and 130 mph wind resistance. For homeowners wanting premium aesthetics, luxury shingles such as CertainTeed Landmark Pro come with 50-year warranties and deeper shadow lines. Metal roofing is also an option for long-term durability, though it costs 2–3× more. We don’t recommend 3-tab shingles in this climate—they fail too quickly in freeze-thaw conditions.

Cost Ranges for Roof Replacement in South Brunswick

For a typical 2,000-square-foot home, expect $8,000–$15,000 for architectural shingles, $12,000–$20,000 for luxury shingles, and $18,000–$30,000 for standing-seam metal. Factors affecting cost include roof pitch (steeper costs more), number of penetrations (chimneys, skylights), and whether decking needs replacement (add $1,500–$4,000). Permits run $200–$500.

Step-by-Step Roof Replacement Process

1. Inspection and Permit

We start with a thorough inspection of your deck, flashing, and ventilation. We then pull a municipal building permit required for roof replacement; Class A fire rating and 90+ mph wind resistance per NJ residential code apply. Licensed roofer with NJHIC registration required for installation.

2. Tear-Off and Deck Repair

Our crew strips all old shingles, underlayment, and flashing. We inspect the plywood deck—if any sections are rotted, we cut them out and replace with new CDX plywood. This step typically takes one day.

3. Underlayment and Ice & Water Shield

Freeze-thaw cycles require ice and water shield underlayment—we install it along all eaves, valleys, and around penetrations. This self-adhering membrane prevents ice dams from backing water under shingles. The rest of the roof gets synthetic felt, which is lighter and more tear-resistant than traditional felt.

4. Flashing and Ventilation

Salt-laden coastal air accelerates metal flashing corrosion, so we use galvanized steel or aluminum flashing. We replace step flashing at walls, pipe boots, and chimney flashing. We also verify ridge vents and soffit vents are unobstructed—poor ventilation shortens shingle life by 50%.

5. Shingle Installation

We install shingles per manufacturer specifications, using stainless steel nails and proper nailing pattern. High summer humidity promotes algae on north-facing slopes where available, so we recommend algae-resistant shingles (e.g., GAF Timberline HD with StreakGuard). We stagger seams for wind resistance.

6. Cleanup and Final Inspection

We magnet-sweep the property for nails, haul away debris, and perform a final walkthrough with you. We then schedule a building inspector sign-off.

Insurance and Warranty Information

Most homeowners insurance covers roof replacement if wind or hail caused damage. We help you file claims and work directly with adjusters. Our workmanship warranty is 10 years (no prorating), and manufacturer warranties range from 30–50 years. We’re BBB accredited and carry $2 million liability insurance.

Local South Brunswick Considerations

South Brunswick’s climate demands specific choices: freeze-thaw cycles require ice and water shield underlayment; salt-laden coastal air accelerates metal flashing corrosion; high summer humidity promotes algae on north-facing slopes where available. We also recommend checking your attic for adequate insulation—many older homes in Kendall Park and Monmouth Junction have only R-19, which should be R-38 minimum to prevent ice dams.
