Yes. NJ Roofing holds NJ HIC License #13VH09260500 and carries both general liability insurance ($2M+) and workers’ compensation coverage on every job. Certificates of insurance are available on request for commercial clients, property managers, and HOA boards. Our license is verifiable at njconsumeraffairs.gov.

Yes — both are core to our business. Residential: shingle roofs, flat sections, gutters, siding, and maintenance plans. Commercial: office buildings, apartment complexes, churches, retail centers, warehouses, schools, and HOA multi-building communities. We’ve worked with clients from individual homeowners to national retail brands throughout New Jersey.

NJ’s climate is tough on roofs — heavy snow and ice in winter, freeze-thaw cycles that force open small cracks, spring rainfall that exploits every weakness, and summer UV heat that accelerates granule loss on shingles and oxidizes rubber membranes. NJ roofs typically need more maintenance than roofs in milder climates, which is why annual inspections are strongly recommended.

Yes. We provide storm damage inspections with full photographic documentation formatted for insurance adjusters. Our team can work directly with your insurance company and provide written damage reports that support your claim. We also offer emergency tarp service after storms to prevent further damage while the insurance process completes.

We serve all of New Jersey with particular depth in Essex County (Newark, Orange, East Orange, West Orange, Bloomfield, Montclair, Livingston), Union County (Elizabeth, Union, Cranford), Bergen County (Teaneck, Englewood, Hackensack, Clifton, Fort Lee), Hudson County (Jersey City, Hoboken, Bayonne), and Morris County (Parsippany, Morristown, Denville). See our full service areas page or call (201) 218-3666 to confirm your town.

Not necessarily. Many leaks can be repaired at a fraction of replacement cost — a cracked pipe boot, failed flashing at a chimney, or a missing shingle can all be fixed with targeted repairs. We inspect your roof first and always recommend the most cost-effective solution. If the leak stems from widespread membrane failure or a very old roof, replacement may be the better long-term investment. See the full Roof Repair FAQ.

Most residential roof repairs in NJ range from $300 to $1,500 depending on type and extent. Simple shingle replacements or sealant repairs are on the lower end. Flashing replacements or small section re-roofing run $500–$1,500. Emergency repairs after major storms may cost more. We provide upfront written pricing before any work begins.

The most common causes in NJ: failed or missing flashing at chimneys, skylights, and wall transitions; cracked or dried-out pipe boot seals around plumbing vents; missing or cracked shingles; clogged gutters causing water backup under shingles; and ice dams in winter forcing water under the membrane. Flat roofs most commonly leak at seams, drain areas, and penetrations.

Yes. Our emergency line is answered 24 hours a day, 7 days a week. Call (201) 218-3666 immediately for active leaks or storm damage. We offer emergency tarp service to stop water infiltration when same-day permanent repair isn’t possible. Emergency repairs are prioritized ahead of all scheduled work.

Most residential roof repairs are completed in a single day — often in a few hours. Larger repairs such as a full section replacement or flashing overhaul may take a full day. Emergency temporary repairs (tarping, emergency patches) are typically completed within hours of your call.

Most residential shingle roofs are completed in 1–2 days. A standard 2,000 sq ft home is typically done in one full day. Larger homes, complex roof shapes, or projects requiring deck repair may take 2–3 days. Commercial flat roof replacements vary by size — a 5,000 sq ft roof typically takes 3–5 days.

Key signs you need replacement: the roof is over 20 years old; you’ve had multiple repairs in the last 2 years with recurring leaks; widespread granule loss in gutters; shingles curling, buckling, or missing across large areas; soft or sagging decking; or estimated repair cost exceeds 30% of replacement cost. A professional inspection gives you a definitive answer.

We install architectural asphalt shingles (GAF and Owens Corning), Elevate EPDM, Mule-Hide EPDM, TPO membranes, modified bitumen, metal roofing, cedar shake, and synthetic slate. For flat roofs we recommend 60-mil EPDM or TPO for NJ’s freeze-thaw climate.

Residential shingle roof replacement in NJ typically runs $8,000–$22,000 depending on size, pitch, material, and tear-off. A standard 2,000 sq ft home with architectural shingles runs approximately $12,000–$16,000 fully installed. Flat roof replacements run $6.50–$14/sq ft installed depending on material. Use our instant quote tool or book a free on-site estimate.

In most NJ municipalities, a permit is required for full roof replacements. NJ Roofing handles permit applications on your behalf as part of every project — included in the estimate at no extra charge. Never let a contractor skip the permit; it can create problems when you sell the home or file an insurance claim.

For most NJ flat roofs we recommend 60-mil EPDM as the top choice. It handles freeze-thaw cycles exceptionally well, has a 20–30 year lifespan, and costs less than TPO. 60-mil TPO is best for energy-conscious owners — the white membrane reflects heat and reduces cooling costs. Avoid 45-mil systems; NJ winters stress thinner materials significantly. See the full Flat Roof FAQ.

With proper maintenance: EPDM — 20–30 years; TPO — 20–25 years; Modified Bitumen — 15–25 years. A silicone recoat at years 10–15 can add 8–12 more years to any of these systems. Without maintenance, expect to lose 30–40% of that lifespan — NJ freeze-thaw cycling is particularly hard on unmaintained flat roofs.

Water pooling 48+ hours after rain is a drainage problem — not normal. It typically means a clogged drain or scupper, inadequate slope, or a depression from insulation compression. Ponding water is the #1 cause of premature flat roof failure in NJ. This needs investigation before the next storm. Call (201) 218-3666.

2026 NJ flat roof installed costs: EPDM 60-mil — $6.50–$9.50/sq ft; TPO 60-mil — $7.50–$11.50/sq ft; Modified Bitumen — $8–$14/sq ft. Add $1–$2.50/sq ft for tear-off and $2–$4/sq ft for new insulation if needed. See our full flat roof cost breakdown.

Leaks around HVAC equipment on flat roofs are almost always caused by failed curb flashing or deteriorated sealant at the curb-to-membrane joint. HVAC technicians frequently access these curbs without resealing. The fix is re-flashing the curb and resealing all penetration edges with professional-grade sealant. Annual inspection after each HVAC service visit prevents recurrence.

For most NJ homes, gutters should be cleaned twice per year — once in late spring after tree pollination and seed drop, and once in late fall after leaves have fully dropped (typically November–December). Homes under heavy tree coverage may need 3–4 cleanings per year. Clogged gutters are one of the most common causes of avoidable roof damage, fascia rot, and foundation issues in New Jersey. See the full Gutter FAQ.

Professional gutter cleaning in NJ typically runs $125–$275 for a standard single-family home, depending on home size, gutter length, and debris level. Two-story and larger homes run higher. Members on NJ Roofing maintenance plans have gutter cleaning included in their plan at no additional per-service charge.

Quality micro-mesh gutter guards significantly reduce debris entry and can cut cleaning frequency in half or more. However, no gutter guard eliminates maintenance entirely — fine debris like shingle granules, seed pods, and roof grit still accumulates over time and requires occasional flushing. NJ Roofing installs and recommends micro-mesh systems rather than foam inserts or screen covers, which tend to fail faster in NJ’s climate.

Signs it’s time to replace gutters: visible cracks, holes, or rust spots; gutters separating at seams or pulling away from the fascia; persistent sagging even after cleaning; peeling paint or water stains on the home exterior below the gutters; water overflowing during light rain; and fascia board rot behind the gutter. Standard aluminum gutters typically last 20–30 years in NJ with proper maintenance.

Yes — significantly. Clogged gutters cause water to back up under the shingle layer at the eave, leading to rot in the roof decking and fascia. In winter, they contribute directly to ice dam formation. Over time, the added weight of debris-filled, water-logged gutters also pulls them away from the fascia, creating gaps that allow water into the wall cavity. Annual gutter cleaning is one of the highest-ROI maintenance items for any NJ home.

At minimum, once per year — ideally in spring or fall. For flat roofs over 15 years old and commercial properties, biannual inspections (spring and fall) are strongly recommended. After any major storm — hail, high winds, nor’easter, or significant snowfall — schedule an additional inspection regardless of your regular schedule.

Our inspections cover: membrane or shingle condition (cracks, granule loss, curling, blistering); flashing at all transitions, walls, chimneys, skylights, and penetrations; gutter and drain condition; seam integrity on flat roofs; signs of ponding water; interior evidence of past water infiltration; and general structural condition. You receive a full written report with photos.

Our maintenance plans include professional inspections, gutter cleaning, penetration and seam resealing, debris removal, minor repairs, priority emergency response, and written inspection reports for warranty and insurance documentation. Homeowner plans start at $25.99/month; commercial flat roof plans start at $99.99/month.

Yes — dramatically. The difference between a roof lasting 20 years and 30+ years almost always comes down to maintenance. Small issues caught early (cracked pipe boot, loose flashing, clogged drain) cost $150–$300 to fix. Left unaddressed, those same issues cause water damage to insulation, decking, and interior finishes costing $5,000–$20,000 to remediate.

Every installation includes a manufacturer material warranty (GAF and Owens Corning offer lifetime limited warranties on qualifying shingle installs; Elevate and Mule-Hide offer 20-year system warranties on EPDM) and our own workmanship warranty covering installation quality. Ask about enhanced warranty programs — as preferred installers we can access longer terms than standard contractors.

Yes — most manufacturer warranties from GAF, Owens Corning, Elevate, and Mule-Hide require documented annual professional maintenance to remain valid. Our written inspection reports satisfy these requirements. Without maintenance records, many warranty claims are denied. This is one of the most important reasons to have your roof inspected annually.

A manufacturer warranty covers defects in the roofing materials themselves. If the shingle or membrane fails prematurely due to a production defect, the manufacturer covers replacement. A workmanship warranty covers the quality of installation — if a leak develops because of how the roof was installed (not a material defect), the contractor covers the repair. Always ask for written copies of both before signing any roofing contract.
