Free storm damage assessments across Camden and Gloucester County.
MJ Roofing has been one of South Jersey's most trusted roofing contractors since 2007 — 19 years and counting. Our two offices in Blackwood and Turnersville put a crew within 35 minutes of every community we serve, from Cherry Hill and Haddonfield to Glassboro, Deptford, and the shore.
We hold the GAF Master Elite certification, a designation earned by roughly the top 2% of roofing contractors in the United States. That certification lets us install GAF's System Plus and Golden Pledge enhanced lifetime warranty systems that most South Jersey roofers cannot offer — and it holds our installations to GAF's audited quality and training standards, year after year.
Our crews know New Jersey's climate does the damage here: hot summers, heavy rain, coastal nor'easters, and freeze–thaw cycles that punish an aging or poorly installed roof fast. Near Brigantine and Atlantic City, salt air adds one more factor — it corrodes standard fasteners and bare aluminum, so shore-town roofs need corrosion-resistant flashing and trim that inland roofs don't.
GAF lifetime shingle systems — the workhorse for South Jersey homes.
Our residential roofing team handles every scope of work, from a targeted leak repair to a complete tear-off and replacement. Every project starts with a photographed inspection of your shingles, flashing, decking, gutters, and ventilation. We tell you exactly what we find — what needs fixing, what can wait, and what a replacement would involve — with no upselling and no surprises on the final bill. We also install siding and gutters, and offer financing on qualifying projects.
Repair is right when damage is isolated; replacement wins when a roof is past its lifespan or repairs keep recurring. Asphalt shingle roofs in New Jersey typically last 20–25 years. Here's the honest breakdown we walk every South Jersey homeowner through:
| Factor | Roof Repair | Roof Replacement |
|---|---|---|
| Best when | A few missing shingles, one leak, flashing failure at a chimney or skylight | Roof is 20+ years old, widespread granule loss, sagging, or repeat leaks in different areas |
| Typical South Jersey cost | Hundreds to a few thousand dollars, scope-dependent | $8,000–$18,000 for most homes, by size, pitch, and material |
| Timeline | Usually same-day | Most homes: 1–2 days |
| Permits (1–2 family homes) | Not required | Since 2018, NJ requires no construction permit for like-for-like reroofs on 1- and 2-family homes |
| Warranty | Workmanship warranty on the repair | GAF System Plus / Golden Pledge lifetime options (Master Elite only) |
Not sure which side you fall on? Our inspection answers it for free — and if a repair is the better move for your budget, that's what we'll recommend, even though a replacement is the bigger job for us.

Every job follows the same six documented steps, so you always know what happens next:
If damage is isolated — a few missing shingles, a single leak, or failed flashing — repair is usually the right call. If your roof is over 20 years old with widespread granule loss, sagging, or repeat leaks in different areas, replacement is more cost-effective long-term. MJ Roofing provides free inspections throughout South Jersey so you get an honest answer before spending anything.
Residential roof replacement in South Jersey typically runs $8,000 to $18,000, depending on roof size, pitch, and materials. Asphalt shingle roofs sit at the lower end; metal systems cost more upfront but last decades longer. Every MJ Roofing estimate is written, itemized by material and labor, and free.
The "25% rule" is a code provision — best known from Florida's building code — that can require full replacement when more than 25% of a roof is repaired within a year. New Jersey has no statewide 25% law, but the same threshold is a useful rule of thumb: once damage covers roughly a quarter of the roof, replacement usually beats piecemeal repair on cost per year of service. Our free inspection tells you which side of that line your roof is on.
Most South Jersey residential roof replacements finish in one to two days. Larger or more complex commercial jobs take three to five days. Once your start date is confirmed, our crew completes the job without leaving it open overnight whenever possible.
Usually not. Since 2018, New Jersey has not required a construction permit for like-for-like roof replacement on one- and two-family homes. Structural changes, commercial buildings, and multi-family properties still require permits — and MJ Roofing handles that paperwork when it applies.
