Why Roof Repairs and Roof Replacement Matter in New Jersey

New Jersey is known for its challenging climate and harsh weather conditions year-round. From summer storms and intense UV rays to heavy snowfall, nor’easters, and salt air due to our coastal position, these conditions can wreak havoc on your roof’s materials over time.

In addition, many NJ homes were built prior to the 21st century. This means they may have older roofing systems that are past their expected lifespan and no longer performing as expected.

Remember that many NJ towns require permits for roof replacement projects. There are also strict building codes that roofers and homeowners must adhere to. Starting your roof replacement early, before small problems become major issues, can reduce headaches and ensure that your roofing project is handled safely and legally.

Time for a New Roof? 10 Major Issues That Indicate It's Time to Replace Your Aging Roof

Replacing your roof is a major undertaking and can be expensive. Understandably, homeowners want to be sure a full roof replacement is truly necessary before beginning work. Regular roof inspections can help you to monitor the health and structural integrity of your roof and ensure that problems are addressed immediately.

In this section, we will show you 10 signs it’s time for a roof replacement that you really should not ignore.

Your Roof Is Over 20 Years Old

Over time, your roof materials naturally lose integrity due to wear, tear, and exposure to the elements. This is particularly true of asphalt shingles. Therefore, if your roof is more than 20 years old, a roof replacement is likely a smarter and more cost-effective choice than roof repairs.

Missing Shingles or Severely Damaged Shingles

If you notice missing, cracking, or curling shingles over a wide area, it is time for a roof replacement. Shingles are a critical component of your roof’s integrity, and damaged or missing shingles can lead to leaky roofs, water damage, and underlying structural damage.

Damaged Flashing

Flashing helps to prevent leaks in vulnerable areas of your roof, such as around chimneys, vents, and where walls and roofs meet. Damaged flashing can allow water to seep in, causing leaks, rotting wood, or damage to underlying roofing materials.

Frequent Leaks or Water Stains

Ongoing leaks or visible signs of internal water damage, such as water stains on your walls, are signs that your roofing system is failing. Even seemingly small leaks can indicate major problems, and there may be significant water damage to your roof’s underlying structure.

Moss, Mold, or Algae Growth

Algae and moss retain moisture, which can degrade roofing materials over time. Significant moss, mold, or algae growth are all signs of problematic moisture buildup, which is likely to get worse over time and eventually cause structural issues. Mold growth can also be hazardous to health.

Granules in Gutters or Driveway

Granules are small stone or mineral particles that help to protect asphalt shingles from the elements and extend their lifespan. A small amount of roof granule loss is normal and unlikely to be an issue. However, if you notice a lot of granules in your gutters or on your driveway, it is a sign that your shingles are deteriorating and losing their protective coating.

Granules can also clog your gutters, preventing them from directing water safely away from the roof. Check your gutters for excess granules as part of your regular roof inspection.

Sagging Rooflines

If your roof is visibly sagging, it is a sign of significant damage and indicates the need for urgent roof replacement. A sagging roof can indicate problems such as trapped moisture, structural damage, rotting wood, weather or wind damage, or even poor installation.

Daylight Visible in the Attic

If you can see visible daylight in your attic, it is a sign of major failures in the underlying roof structure or gaps in the sheathing. Either is a major roofing problem and indicates the urgent need for significant roof repairs or a roof replacement.

Rising Energy Bills and Poor Energy Efficiency

One of the roles of a roof is to provide proper insulation to your home. If your energy efficiency has fallen, poor insulation or ventilation from an aging roof, making your HVAC system work harder, may be the culprit. Paying attention to your energy bills will help you to monitor your roof’s condition.

Multiple Repairs in the Last 2–3 Years

Repairs can be a cost-effective way to rectify minor roofing problems and extend the life of your roof. However, there comes a point at which repairs are no longer cost-effective compared to full roof replacement. If you have had to undertake multiple costly repairs in the last 2-3 years, it is likely time to invest in a roof replacement instead.

Storm or Hail Damage Across Large Sections

Storms are common in New Jersey. If your roof has suffered significant storm damage, it may be more cost-effective to replace rather than repair it. Roofing services often qualify for insurance coverage in the event of storm damage, so always check your policy before you pay for costly repairs or a roof replacement yourself.

What to Do If You Notice These Signs

If you notice missing or damaged shingles, mold growth, a sagging roof, visible water stains, or any of the other signs we identified above, follow these steps to take the headache out of your roof repairs or replacement.

Document the Damage

Take photographs of any visible damage, no matter how seemingly small, including both interior and exterior shots. Keep a note of the dates the pictures were taken, and compare images taken on different days if you suspect the damage is getting worse.
