MJ Roofing LLC is a GAF Master Elite roofing contractor serving all of Salem County, NJ — from Pennsville and Penns Grove along the Delaware River to Woodstown, Carneys Point, and Salem City in the county’s agricultural interior. Homes along Salem County’s western corridor face above-average wind uplift and moisture exposure from the river, and proper installation — including Ice & Water Shield compliance under New Jersey building code — is not optional. Our licensed team handles residential and commercial roofing, roof repair in South Jersey, and full roof replacement throughout all 15 Salem County municipalities, with free on-roof inspections and same-day response on emergency calls.
What Roofing in Salem County Actually Requires
Salem County roofing is not the same job as roofing in Philadelphia’s suburbs. New Jersey’s IRC-aligned building code (R905.1.2) mandates Ice & Water Shield on the first 36 inches from the eave edge on all residential roofs — and in Salem County’s climate zone, extending that coverage to valleys and penetrations is standard practice for any contractor who intends the roof to last. The county’s western communities — Pennsville Township, Penns Grove Borough, and Carneys Point Township — sit along the Delaware River, where wind-driven moisture and freeze-thaw cycling accelerate fascia rot and flashing failure faster than inland areas. Salem City, the county seat founded in 1675, is dense with older Colonial and Victorian-era homes that often have cut-up roof lines, multiple penetrations, and original wood decking that must be inspected — and in many cases replaced — before new shingles go down. Woodstown and Pilesgrove, in the county’s rural interior, run larger agricultural properties where barn roofs and detached-garage flat sections require commercial-grade TPO or EPDM systems alongside the main residence. Every job we start in Salem County begins with a free inspection where we physically access the roof, document findings with photos, and walk you through exactly what needs to happen before we ask for a commitment.
| Salem County Zone | Common Roof Type | Primary Risk Factor |
|---|---|---|
| Delaware River Corridor (Pennsville, Penns Grove, Carneys Point) | Asphalt shingle, older slate | Wind uplift, moisture infiltration |
| County Seat & Historic Core (Salem City, Mannington) | Colonial/Victorian cut-up rooflines | Multiple penetrations, aged decking |
| Rural Interior (Woodstown, Pilesgrove, Elmer) | Asphalt + flat/commercial sections | Agricultural structures, flat drainage |

Our Roofing Services in Salem County
MJ Roofing LLC brings the full range of residential and commercial roofing services to Salem County homeowners and property managers.
Roof Replacement in South Jersey: Full tear-off and replacement using GAF shingles — we are one of fewer than 2% of roofing contractors nationally to hold GAF Master Elite certification, which requires verified installation standards, licensing, insurance, and a commitment to ongoing training. For Salem County homeowners, that certification means your warranty is backed by GAF directly, not just by the contractor.
Roof Repair: Leak diagnosis, flashing repair, shingle replacement, and valley re-sealing. Salem County’s older housing stock — particularly in Salem City and Pennsville — frequently has failing step flashing at dormers and chimneys, which is one of the most common sources of attic moisture damage in the region.
Commercial Roofing: Flat roof systems in TPO roofing, EPDM, and modified bitumen for commercial properties, agricultural outbuildings, and multi-unit residential. We handle both new installation and re-cover systems where the existing deck is sound.
Emergency Roof Repair: Storm damage, wind-lifted sections, and active leaks — we offer same-day emergency response throughout Salem County.
Siding & Gutters: Vinyl and James Hardie fiber cement siding installation; seamless gutter systems to manage Salem County’s average 45+ inches of annual precipitation.
Why Salem County Homeowners Work With MJ Roofing
GAF Master Elite status means your roof is installed to manufacturer spec, not just close enough. GAF’s System Plus and Golden Pledge warranty tiers — available only through Master Elite contractors — cover both materials and labor for up to 25 years and are transferable if you sell the home.
We climb your roof. Unlike some large regional contractors who do drive-by estimates or drone-only inspections, our crews physically access every roof before quoting. We take photos, show you what we find, and give you a written scope.
No pressure sales. We give you the inspection report, explain your options, and let you decide. We do not use high-pressure same-day-close tactics. Our pricing is transparent: we’ll tell you what materials cost, what labor costs, and what your total is before a contract is signed.
Storm insurance claims. We work directly with homeowners through the insurance claim process — documentation, adjuster meetings, and supplementing for code-required upgrades like Ice & Water Shield that some insurers initially exclude.
FAQ: Roofing in Salem County, NJ
How much does a roof replacement cost in Salem County, NJ?
A full asphalt shingle roof replacement in Salem County typically runs between $8,000 and $18,000 for a standard single-family home, depending on roof size, pitch, current deck condition, and material choice. Homes in Salem City and Pennsville with complex rooflines or original wood decking often land at the higher end due to deck replacement costs. We provide itemized written estimates — contact us for a free on-roof inspection and quote specific to your property.

What is a GAF Master Elite roofing contractor?
GAF Master Elite is the highest certification tier offered by GAF, North America’s largest roofing manufacturer. Fewer than 2% of roofing contractors in the U.S. qualify. To earn and maintain it, a contractor must be properly licensed in their state, carry adequate insurance, demonstrate a commitment to ongoing training, and maintain a strong customer satisfaction record. For homeowners in Salem County, working with a Master Elite contractor unlocks GAF’s top warranty tiers — including the Golden Pledge, which covers both labor and materials for up to 25 years.
Do I need a permit for a roof replacement in Salem County, NJ?
In most Salem County municipalities, a building permit is required for a full roof replacement (tear-off and re-roof). Permit requirements and fees vary by township or borough — Pennsville, Salem City, and Woodstown each have their own building departments. MJ Roofing pulls all required permits as part of our standard process; you do not need to manage this separately.
Can you help with a storm damage insurance claim for my Salem County roof?
Yes. We document storm damage thoroughly — photos, written scope, material quantities — and work alongside your insurance adjuster through the claims process. We also identify code-upgrade items (such as Ice & Water Shield requirements under NJ building code) that some initial claim estimates omit, and we can assist with supplementing those costs.
