Dried, cracked or curling shingles

Signs of a Failing Roof

If your roof is leaking, shingles are missing or curling, or you’re seeing stains, peeling paint, or mold indoors, your roof may be failing in more than one area. Just as important, poor attic ventilation can trap heat and moisture, which speeds up shingle wear and drives up energy costs. Catching these warning signs early helps prevent expensive interior and structural damage.

Signs of a Failing Roof

Roof issues like leaks, peeling paint, stains, mold, missing shingles, and dark spots are often clear signs that your roof needs attention. Inadequate attic ventilation can also trap moisture, leading to further damage and increased energy bills as your cooling and heating systems work harder. Identifying and addressing these problems early can help protect your home from costly repairs, improve energy efficiency, and maintain the overall health of your roof. Don't wait—taking action now can save you time and money in the long run.

Missing, Cracked, or Curling Shingles

Dried, cracked or curling shingles

If you notice shingles that are broken, lifting up, or have fallen off, your roof is no longer sealed against moisture. High winds (common near the coast and open fields) often tear away aging shingles, leaving your home exposed.

Dark Streaks or Moss Growth

Dark spots on your roof could indicate vegetation, mold, or algae growth, or the loss of protective granules on shingles.

Black algae streaks and moss patches often appear on older roofs here due to our humid summers and coastal air. While partially cosmetic, they can indicate moisture retention and shingle aging. GAF’s algae-resistant shingles are a great solution to this regional issue.

Peeling Paint or Rotting Trim

Blistering or peeling interior or exterior paint

Peeling exterior paint near the roofline or decaying soffits can result from poor attic ventilation and roof leaks. Many New Jersey homes have attics; if heat and moisture get trapped (for example, from heating systems or lifestyle humidity), it can damage wood and paint. This often signals the roof and ventilation system aren’t performing well.

Leaks in the Attic

A leak in the attic

After a storm or wind-driven rain, check your attic for leaks. Ice damming can also cause water to enter if your shingle underlayment is inadequate or if flashing around roof joints, like chimneys and pipes, has deteriorated.

Higher Energy Bills & Drafts

Poor attic ventilation can raise cooling costs by trapping hot air, forcing your system to work harder. Moisture buildup due to inadequate insulation can reduce insulation efficiency, leading to higher energy costs.

A failing roof can allow drafts and reduce insulation effectiveness. If your heating and cooling costs have spiked, your roof (and attic ventilation) might be to blame. Inconsistent indoor temperatures or excess attic heat in summer are clues that your roof system is compromised.

If you spot one or more of these warning signs, it’s wise to have a professional inspect your roof. Because New Jersrsey homes range from seaside cottages to large family colonials, our team will evaluate your specific home’s roof age, style, and even factors like chimney flashing or fuel-type venting. We’ll give you an honest assessment on whether you can repair or need a full roof replacement. Catching problems early can prevent costly interior damage and structural issues. Don’t wait for the next big storm – if your roof is failing, schedule a free inspection with our local experts and protect your home before small issues become major headaches.

Seamless Gutters and Gutter Guard Protection

In addition to expert roof replacement, we install seamless aluminum gutters and Hydro-Flo micromesh gutter guards to create a complete water-management system that protects your home from top to bottom. Properly sized and pitched gutters help move rainwater away from your roofline efficiently—reducing the risk of fascia rot, stained siding, soil erosion, and water pooling near the foundation. Because seamless gutters are formed on-site in one continuous run, they deliver a clean, finished look with fewer joints, which means fewer opportunities for leaks and far less maintenance over time.

To take that protection even further, we pair your new gutters with our Hydro-Flo micromesh gutter guard system. Hydro-Flo uses a fine stainless-steel micromesh screen that allows water to enter the gutter while blocking leaves, pine needles, seed pods, roof grit, and other debris that commonly cause clogs and overflow. That clog resistance helps prevent the chain reaction that leads to problems like overflowing gutters, washed-out landscaping, basement moisture issues, and ice buildup in colder months. The result is more consistent drainage, fewer cleanings, and longer gutter life.

Whether you’re upgrading your roof, adding solar, or improving drainage around your home, our gutter systems are designed to integrate seamlessly with your new roofing system. The finished combination delivers full-home protection, improved performance in heavy rain, and a noticeable boost in curb appeal—all with a solution that’s built to last.

In addition to expert roof replacement, we install seamless aluminum gutters and Hydro-Flo micromesh gutter guards to protect your home’s foundation and landscaping. Seamless gutters are formed in one continuous run for a clean look, fewer leaks, and less maintenance.

Paired with Hydro-Flo gutter guards, your gutters stay flowing by blocking leaves, debris, and roof grit, helping reduce clogs and the need for regular cleanings. Whether you’re upgrading your roof, adding solar, or improving drainage, our gutter systems integrate perfectly for full-home protection and enhanced curb appeal.

Professional Site Preparation

Tarping a residential roof and protecting landscaping prior to old roof removal during a professional roofing project

Before removing the existing roof, our team carefully tarps the roof and protects surrounding landscaping to prevent debris damage and maintain a clean job site. Proper preparation is a critical step in every professional roofing project, helping safeguard plants, walkways, and property while ensuring a smooth and efficient roof replacement process.

Removal of Old Roofing Shingles

Removal of Existing Roofing Shingles & Damaged Sheathing

On installation day, our trained crew will carefully remove your old roofing shingles and underlayment, right down to the plywood deck.

Replace Damaged Sheathing

Replace Damaged Sheathing

If we find any soft spots, rot, or compromised plywood, we remove it and install new roof sheathing. A strong, smooth deck is the foundation of a long-lasting roof, because it helps shingles lay flat, fasteners hold properly, and the entire roofing system perform as designed for years to come.

Weatherproofing Installation

Install New Ice & Water Shield and Felt Buster

Next, we install high-quality GAF underlayments and weather barriers. Ice & Water Shield is applied in vulnerable areas (like eaves and valleys) to guard against ice dams and wind-driven rain. We then roll out a breathable FeltBuster® or DeckArmor™ underlayment across the roof deck for an added layer of protection beneath your shingles. These elements are especially important in New Jersey, where sudden storms can dump heavy rain or snow – your roof will be ready.

GAF Timberline HDZ Shingle Installation

Install GAF HDZ Shingles & Liberty Low Slope

With the prep work done, we install your new Timberline HDZ shingles in the color you’ve chosen. Our crew uses proper GAF nailing techniques and aligns each shingle for both beauty and durability. For any low-slope sections of your roof (like certain porch or dormer areas), we use GAF’s Liberty™ roofing membrane instead of shingles to ensure a waterproof seal.

New Attic Fan, Ridge Vent & Chimney Flashing

New Attic Fan, Ridge Vent & Chimney Flashing

We handle the details that protect your home long after install day. That includes proper attic ventilation with ridge vents and/or attic fans to reduce heat and moisture buildup.

We also replace critical flashings—chimney flashing, vent pipe boots, and other metal transitions—using clean, watertight seams to prevent leaks during heavy rain or wind-driven storms.

Skylight Replacement or New Skylight Installation

New Velux Skylight

If your skylights are fogging, dripping, or staining drywall, replacing them during a roof project is the best time to ensure proper sealing and flashing. We can replace existing skylights or add new ones without disturbing your new shingles later.

We install premium Velux® skylights with energy-efficient glass and manufacturer-specific flashing, integrated with proper underlayment for a clean look and reliable, leak-resistant performance.

Final Cleanup & Full Inspection

Cleanup, Removal & Disposal

Once the last shingle is nailed down, we conduct a thorough cleanup of your property. Our team uses magnets and tarps to ensure no nails or debris are left behind – your yard will be as neat as we found it. Finally, we perform a detailed final inspection with you, making sure every aspect meets our high standards and that you are completely satisfied.

GAF Warranty Registration and Documentation

GAF Lifetime Warranty Registration

After the field team completes your roof replacement and the final walkthrough is done, we take care of the next critical step: registering your new roof with GAF to help activate your Lifetime Warranty coverage. 

You’ll receive clear warranty paperwork for your records, so you have everything you need for future reference—whether you stay in the home for decades or plan to sell later.

From the first nail to the final inspection, our focus is on delivering a roof that’s built to last – installed with quality, speed, and utmost respect for your property. We work hard to minimize disruptions to your daily life while maintaining the highest construction standards.

    …real merit…converting to solar makes total sense, especially in new jersey, but didn’t realize that until I did my research...being that i lacked the technical, financial and logistical knowledge regarding the solar business, finding a knowledgeable and reputable solar company was my top priority...i wanted to work with a solar company that had time to answer all my questions and a company that was rooted in the state/community where i lived...i figured and was correct, that the permit process would be much easier with working with a local NJ solar company…after scouring the regular sites that host reviews, i stumbled across highly rated, Green Sun Energy Services (GSES)...Upon reaching out to GSES, Glen Koedding immediately contacted me...after an initial exchange of concerns, thoughts and expectations, Glen was able to map out an outline that was not only affordable, but a plan that would enable me to mitigate obsolescence and optimize new and emerging technology…once I was finally convinced that solar power was not only environmentally desirable but it would eventually save me a significant amount of money, I asked Glen from GSES, “what’s the catch?”…being extra cautious on a major acquisition, I must have asked this question to Glen, perhaps a dozen times, up to and after signing the contract agreement…Glen would say, “there is no catch”…being the ultimate cynic, I would always have a little doubt…here I am 8 months later and happy to report, “there is no catch”…the installation went smoothly, federal tax credits, NJ incentives are either received or in place and my utility bill is now pennies on the dollar…Glen is super “user friendly” and has not only answered every question I had, he helped me choose the solar equipment that met my current and future needs…I would recommend Green Sun Energy Systems to anyone considering converting to solar energy…
