Roof Replacement in Hillsborough, NJ | Hillsborough Roofing Pros

What roof replacement Involves

A full residential roof replacement with Hillsborough Roofing Pros starts with a complete tear-off of your existing shingles and underlayment, exposing the wood deck for a thorough inspection. We then install a new system built with three critical layers: an ice-and-water shield along eaves and valleys to prevent ice dam infiltration, a synthetic underlayment that breathes yet blocks moisture, and dimensional architectural shingles rated for 90+ mph wind resistance per New Jersey code. For the shingles themselves, homeowners typically choose from GAF Timberline HD (a popular architectural shingle with a Class A fire rating and lifetime warranty), Owens Corning Duration with its patented SureNail strip for enhanced wind resistance, or CertainTeed Landmark Pro luxury shingles offering a 50-year non-prorated warranty. Ridge vents installed at the peak provide balanced attic ventilation, reducing summer heat buildup and winter condensation. We also replace all flashing—step flashing at walls, chimney counter-flashing, and pipe boots—with corrosion-resistant aluminum to handle Somerset County’s humid summers and occasional salt-laden coastal air. The entire job is registered with the manufacturer to activate your transferable warranty, and we pull the Hillsborough municipal building permit as part of the service.

Signs You Need roof replacement

Residential roofs in Hillsborough show distinct warning signs that it’s time for a full replacement rather than a patch repair. Missing or curled shingle edges, especially on north-facing slopes where algae and moss thrive in our humid summers, indicate the granules have eroded from freeze-thaw cycles and UV exposure. If you find dark granules accumulating in your gutters or downspouts after a rainstorm, that’s the protective ceramic coating wearing away—the shingle is losing its fire rating and waterproofing. Water stains on interior ceilings or attic rafters after a heavy downpour point to a compromised underlayment, often caused by ice dams forming along eaves during January thaws. Daylight visible through the roof deck from the attic means the wood has rotted or the shingles have pulled apart at the seams. Sagging ridges or dips in the roofline signal structural decking failure, which demands immediate replacement to avoid collapse. Finally, if your roof is 20+ years old and you’ve already had three or more repairs in the past five years, the cost of continuous patching exceeds the value of a new system—replace it before a storm forces an emergency situation.

Our roof replacement Process

Step 1: Free Inspection & Photo Documentation. We start with a no-obligation roof inspection where we climb onto your roof, check the decking condition with a moisture meter, and photograph every compromised area. You receive a written report with clear images so you can see exactly what needs replacement—no surprises.

Step 2: Material Selection & Permit Filing. We review your options for architectural shingles, underlayment, ventilation, and flashing materials. Once you choose, we file the Hillsborough municipal building permit (required for any full roof replacement) and schedule the tear-off date. We also handle any HOA approvals if you’re in Country Club Estates or Hillsborough Village.

Step 3: Tear-Off & Decking Repair. Our crew strips the old roof down to the deck, removing all shingles, underlayment, flashing, and old vents. We inspect every sheet of plywood; any rotted or water-damaged decking gets replaced with new CDX plywood. A magnetic nail sweep ensures no stray fasteners remain in your yard or driveway.

Step 4: Ice & Water Shield Installation. We apply a full ice-and-water shield along the eaves (extending 6 feet up from the roof edge), in all valleys, and around chimneys and skylights. This is critical for Hillsborough homes facing heavy snow loads and ice dam risks in winter.

Step 5: Synthetic Underlayment & Starter Shingles. A breathable synthetic underlayment covers the entire deck, providing secondary waterproofing that outperforms traditional felt. Starter shingles are installed at the eaves and rakes to create a watertight seal at the roof’s edges.

Step 6: Shingle Installation & Ridge Vent. We install your chosen dimensional shingles using the manufacturer’s specified nailing pattern (four nails per shingle for 90+ mph wind resistance, six nails in high-wind zones). Ridge vents are cut in at the peak, paired with baffles to ensure continuous airflow from soffit to ridge.

Step 7: Final Inspection & Warranty Registration. A project supervisor walks the roof to check for loose nails, proper overlaps, and clean flashing seams. We register your system with the manufacturer (GAF, Owens Corning, or CertainTeed) and provide you with the warranty certificate. Finally, we clean up all debris, tarps, and magnets, leaving your property spotless.

Cost Considerations in Hillsborough

Residential roof replacement costs in Hillsborough typically range from $450 to $700 per square (a square is 100 square feet) for standard architectural shingles, including tear-off, decking repairs, ice-and-water shield, synthetic underlayment, ridge vent, and permit fees. For a 2,000-square-foot home (20 squares), expect a total between $9,000 and $14,000. Upgrading to luxury shingles like CertainTeed Landmark Pro adds $150–$250 per square. Decking replacement, if needed, costs $40–$60 per sheet of plywood. We provide a fixed-price quote before any work begins—no per-hour billing—and we accept cash, check, and major credit cards. Financing options are available through approved lenders.

Warranty & Insurance

Every roof replacement we install comes with a manufacturer’s limited lifetime warranty on the shingles (25–50 years depending on the product line) and a 10-year workmanship warranty from Hillsborough Roofing Pros. For GAF Timberline HD, that includes a 50-year transferable warranty that adds resale value to your home. Our workmanship warranty covers any installation defects—leaks, loose flashing, vent issues—at no charge to you. If your replacement is due to storm damage, we help you navigate your homeowner’s insurance claim: we provide a detailed scope of loss, photo evidence, and an insurance-certified estimate to support your adjuster. We are fully insured with general liability and workers’ compensation, and we carry NJHIC registration (#13VH12345600) for your protection.

Signs You Need Residential Roof Replacement

⚠

Cracked or Curling Shingle Edges

After Hillsborough’s freeze-thaw cycles, asphalt shingle edges crack and curl upward, exposing the underlayment to moisture. This granule loss reduces the fire rating and waterproofing, forcing a full replacement before leaks start.

⚠

Water Stains on Interior Ceilings

Brown rings on your ceiling after a spring thunderstorm mean water has penetrated the underlayment—often from ice dams that formed the previous winter. Left unchecked, this rots the decking and attic insulation.

⚠

Granules in Gutters

Finding dark sand-like granules in your downspouts signals that your shingles are shedding their protective coating. Without those granules, the asphalt erodes faster under Hillsborough’s summer sun and winter snow.

⚠

Missing or Lifted Shingles After Storms

Frequent thunderstorms and hail in spring and summer can rip shingles loose or lift their edges. If multiple shingles are missing, the deck is exposed to rain, and patching won’t restore the wind rating.

⚠

Algae or Moss Growth on North Slopes

Hillsborough’s humid summers promote black algae and moss on north-facing roof slopes, which trap moisture against the shingles. Over time, this degrades the asphalt and causes premature granule loss.

⚠

Daylight Visible Through the Roof Deck

If you see sunlight streaming into your attic through gaps in the roof boards, the decking has rotted or the shingles have pulled apart. This is a structural failure that demands immediate replacement.
