East Hanover sits between two rivers the Whippany to the west and the Passaic to the east and that geography does real things to your roof. The elevated moisture from the surrounding wetlands and the Troy Meadows corridor accelerates algae growth, softens underlayment over time, and makes ice dam formation along your eaves more likely every winter. A roof installed without accounting for those conditions is one that starts failing sooner than it should.
Then there’s the housing stock. A big portion of East Hanover’s homes were built in the 1950s through the 1970s split-levels, bi-levels, ranches and many of them are on their second or third roofing system, or well overdue for one. That era of construction has specific structural characteristics: lower pitches, older decking, ventilation setups that may not meet today’s standards. We actually look at what’s there before quoting anything.
What you get when the job is done right is simple: a dry home, a roof that handles freeze-thaw cycles without cracking open, manufacturer-backed warranty coverage that protects your investment for decades, and a contractor you can actually reach if something comes up. That’s the outcome that matters.
Proline Construction is a family-owned roofing and general contracting company serving northern New Jersey since 2018. We hold both GAF Preferred Contractor status and Owens Corning Platinum Preferred Contractor status the highest tier Owens Corning offers which means customers in East Hanover have access to enhanced manufacturer warranties that most local contractors simply cannot provide. Add in BBB accreditation with an A rating and more than five consecutive years on HomeAdvisor’s Best list, and you have a track record that’s been verified by third parties, not just stated on a website.
East Hanover is part of our core Morris County service area. We’re familiar with the township’s permit requirements, the Construction Department’s process, and the specific conditions that affect homes throughout the area from the older neighborhoods near Mount Pleasant Avenue to the properties closer to the Passaic River corridor. When you call, you’re talking to people who know this town.
It starts with a free consultation. Our owner comes out personally, looks at your roof, and gives you an honest assessment not a sales pitch. If there’s an issue worth addressing, you’ll hear about it clearly and specifically. If there isn’t, you’ll hear that too. East Hanover Township requires both a zoning permit and a construction permit before roofing work begins on a residential property, and we handle that process as part of the job not as an add-on or an afterthought.
Once the project is scheduled, our crew arrives on time and works efficiently. Full tear-off and replacement projects are routinely completed in a single day, which matters when you have a household to run and a driveway that needs to be functional. After the tear-off, a magnetic nail sweep is run across the yard and surrounding areas to collect loose nails a step that’s easy to skip and that we don’t skip.
When the work is done, you get a full walkthrough, documentation of the manufacturer warranties from GAF or Owens Corning depending on your materials, and a workmanship warranty that covers the installation itself. If something comes up after the job is finished, there’s a real person to call.

Most East Hanover homeowners end up choosing architectural asphalt shingles, and for good reason they’re built for the kind of climate Morris County delivers, carry 30 to 50 year lifespans, and provide the best overall value for the investment. But they’re not the only option, and they’re not automatically the right one for every home. Metal roofing is worth a serious look if you want a 40 to 70 year lifespan and a material that handles ice and moisture better than anything else on the market. Cedar shake brings a natural aesthetic that suits East Hanover’s established, well-kept neighborhoods, and with proper maintenance it holds up for 30 to 40 years. Tile roofing is available for homes where the structure supports it.
Beyond residential work, we also handle commercial roofing for the Route 10 corridor flat roof systems, membrane maintenance, and commercial-grade installation for the retail and office properties that define East Hanover’s business district. With the Arena campus redevelopment bringing new tenants into former Novartis buildings along Route 10 and Farinella Drive, commercial roofing demand in this township is growing. Whether it’s a split-level off Mount Pleasant Avenue or a commercial property near East Hanover Plaza, the scope of work gets the same level of attention.
New roof installation, full roof replacement, residential roofing, commercial roofing, roof framing, shingle roofing, metal roofing, cedar shake roofing, and tile roofing are all part of what we bring to East Hanover.
Yes, and it’s a two-step process specific to East Hanover Township. Before a construction permit is issued, you need a zoning permit from the township the fee for roofing work on a single-family home is $10, but the step itself is mandatory and cannot be bypassed. After that, a construction permit is required under the New Jersey Uniform Construction Code, and the township’s enforcing agency has 20 business days to grant or deny a completed application.
This matters more than most homeowners realize. Contractors who skip permitting aren’t just cutting paperwork they’re exposing you to real risk. If unpermitted work is discovered during a future home sale or insurance claim, it can create title complications and potentially void your coverage. We handle the permit process as a standard part of every project, so you’re not left navigating it on your own or discovering a problem years later.
For a typical residential roof replacement in New Jersey, most homeowners spend somewhere between $11,000 and $30,000 depending on the size of the home, the materials selected, and the complexity of the job. East Hanover’s housing stock which includes a lot of split-levels, bi-levels, and colonials tends to fall in the mid-to-upper range of that window because of roof geometry and the additional considerations that come with older decking and ventilation systems.
Material choice is one of the biggest variables. Architectural asphalt shingles are the most cost-effective option and the most common in this area. Metal roofing costs more upfront but lasts significantly longer and performs better in Morris County’s freeze-thaw conditions. Cedar shake and tile sit at the higher end of the cost range. The best way to get an accurate number for your specific home is through a free consultation we give you a real estimate based on what’s actually there, not a ballpark figure designed to get you to sign something.
The most obvious signs are visible from the ground: shingles that are curling, cracking, or missing entirely; granules collecting in your gutters after rain; dark streaking or moss growth on the roof surface. In East Hanover’s moisture-rich environment sitting between the Whippany and Passaic Rivers with Troy Meadows nearby algae and moss growth tend to accelerate faster than they would in drier inland towns, so those surface signs can appear earlier than you’d expect.
Inside the home, water stains on ceilings or in the attic after a storm are a clear signal. But some of the most important warning signs are less dramatic: a roof that’s 20 to 25 years old and has never been replaced, flashing around chimneys or skylights that’s pulling away, or an attic that feels unusually warm in summer or damp in winter. If your home was built in the 1950s through 1970s which covers a lot of East Hanover’s residential neighborhoods and you haven’t had a professional look at the roof in the last few years, a free consultation is worth scheduling before the next nor’easter makes the decision for you.
For most homes in Morris County, including East Hanover, architectural asphalt shingles are the practical choice. They’re designed to handle the freeze-thaw cycling that defines northern New Jersey winters, they carry 30 to 50 year lifespans when properly installed, and they’re available with enhanced manufacturer warranties through certified contractors like us. They also handle the humid summers in this area without degrading quickly, which matters when you’re this close to river corridors and wetlands.
That said, metal roofing is worth a serious look for homeowners who want the longest possible lifespan and the best performance in ice and moisture conditions. A metal roof can last 40 to 70 years, sheds snow more effectively than shingles, and doesn’t create the conditions that lead to ice dam formation the way traditional roofing can. The higher upfront cost is real, but so is the return metal roofing in the eastern U.S. has been documented at up to 95.5% ROI at resale. The right material depends on your specific home, your budget, and how long you’re planning to stay all of which is worth talking through during a free consultation.
Ice dams form when heat escaping from the living space warms the upper portion of the roof, melting snow that then runs down toward the colder eaves and refreezes. That wall of ice traps water behind it, and that water works its way under shingles and into the structure. In East Hanover, the combination of Morris County’s cold winters and the elevated moisture levels near the Passaic River and Whippany River corridors makes ice dam conditions more common than in drier, more elevated parts of the state.
A properly installed roof addresses this at multiple levels. Ice and water shield a self-adhering membrane installed along the eaves and in valleys provides a waterproof barrier in the areas most vulnerable to ice dam infiltration. Proper attic ventilation keeps the roof deck temperature more uniform, which reduces the melting-and-refreezing cycle that creates dams in the first place. These aren’t optional upgrades they’re part of what a correctly installed roof in this climate includes. If your current roof is showing signs of ice dam damage, or if you’ve had interior water intrusion after winter storms, that’s worth addressing before the next season.
In New Jersey, roofing contractors are required to be registered as a Home Improvement Contractor with the NJ Division of Consumer Affairs. That’s the baseline it means they’re legally permitted to do the work. But registration alone doesn’t tell you much about quality or accountability. The credentials that actually matter are manufacturer certifications, third-party ratings, and a verifiable track record across multiple years.
GAF Preferred Contractor status and Owens Corning Platinum Preferred Contractor status both require verified licensing, insurance, and demonstrated installation standards they’re not just a logo you can buy. BBB accreditation with an A rating requires meeting ongoing standards for transparency and responsiveness. Sustained ratings on platforms like HomeAdvisor over five or more years reflect consistent performance across hundreds of real projects, not a recent push. When you’re making a $15,000 to $25,000 investment in your home, those are the signals worth checking not just the quote on the page. We hold all of them, and they’re all verifiable before you ever pick up the phone.
