Common Roofing Problems in Older New Jersey Homes

Owning an older home in beautiful Mt. Laurel, New Jersey, comes with a unique sense of charm, character, and history. The tree-lined streets, established neighborhoods, and classic architectural styles are part of what makes this area so desirable. However, with the passage of time comes the inevitable wear and tear on even the most robust structures, and roofing problems, your home’s primary shield against the unpredictable South Jersey weather, is often the first place to show its age.

For owners of historic or older properties in Mt. Laurel, understanding the common roofing problems that can arise is crucial for preserving your home’s integrity, value, and comfort.

Here are some of the most common roofing problems we encounter in older Mt. Laurel homes and how professional intervention can help:

1. Age-Related Roofing Problems:

The most obvious issue with an older roof is simply its age. Roofing materials, most commonly asphalt shingles in homes built from the mid-20th century onwards, have a finite lifespan, typically ranging from 20 to 30 years depending on the quality of the material and installation, as well as exposure to the elements.

• Problems: As asphalt shingles age, they begin to show signs of deterioration like cracking, curling (either cupping upwards or clawing downwards), blistering, and significant granule loss. Granules are the gritty surface of asphalt shingles that protect the asphalt layer from UV rays. Once they wear away, the shingle becomes vulnerable and deteriorates rapidly. Older roofs may also have missing shingles due to weakening seals or wind damage.
• Solutions: A thorough roof inspection is the first step. If the age and overall condition indicate the roof is nearing or past its lifespan, a full roof replacement is often the most cost-effective long-term solution. Spot repairs might offer a temporary fix for minor issues, but they won’t stop the aging process of the rest of the roof. For homes with older materials like slate or wood shake, repairs require specialized knowledge to match existing materials and techniques.

2. Deteriorated or Damaged Flashing roofing problems:

Flashing is a critical component of any roof system. These are thin pieces of material, usually metal, installed in areas where the roof meets a vertical surface, such as around chimneys, vents, skylights, and in valleys where two roof sections meet. Flashing is designed to create a watertight seal, directing water away from vulnerable areas.

• Problems: In older homes, flashing can be made from various materials that may have corroded, cracked, or come loose over time. Settling of the house structure can also cause flashing to pull away. Damaged flashing is a very common source of roof leaks, often leading to water stains on ceilings and walls inside the home, particularly near chimneys or in attic spaces.
• Solutions: Professional roofers can repair or replace damaged flashing. This often involves carefully removing the old flashing, inspecting the underlying structure for rot or damage, and installing new, properly sealed flashing materials. For historic homes, matching the appearance of original flashing might be a consideration.

3. Underlayment Issues:

Beneath the visible roofing material lies the underlayment, an additional layer of protection installed directly onto the roof deck. In older homes, the underlayment might be felt paper or an early form of asphalt-saturated material, which can become brittle, torn, or deteriorated over decades.

• Problems: A compromised underlayment offers little defense if water penetrates the outer roofing layer through missing shingles or faulty flashing. This can lead directly to rot in the roof deck, structural damage, and leaks into the home.
• Solutions: Underlayment issues are typically discovered during a roof inspection or when the outer roofing material is removed for repair or replacement. Addressing this requires replacing the old underlayment with modern, durable materials designed to provide a robust secondary barrier against moisture.

4. Inadequate Ventilation:

Proper attic ventilation is essential for the longevity of any roof, but it’s a particularly common issue in older homes that may not have been built with modern ventilation standards in mind.

• Problems: Poor ventilation traps heat and moisture in the attic. In winter, this can lead to ice damming, where melting snow refreezes at the eaves, forcing water under shingles. In summer, excessive heat can bake the shingles from beneath, accelerating their deterioration. Moisture can also lead to mold growth and rot in the roof deck and rafters.
• Solutions: A roofing professional can assess your attic’s ventilation and recommend improvements. This might involve installing or improving soffit vents, ridge vents, or other types of exhaust vents to create proper airflow, keeping the attic cooler in summer and reducing moisture buildup in winter.

5. Structural Concerns:

While less common, the underlying roof structure in older homes can sometimes present problems, especially if it has been subjected to repeated moisture damage or wasn’t originally designed to handle modern roofing materials.

• Problems: Sagging sections of the roof ridge or slopes can indicate weakened rafters or decking. This is a serious issue that compromises the structural integrity of the entire roof system. Past repairs that weren’t done correctly can also lead to ongoing structural stress.
• Solutions: Addressing structural issues requires the expertise of a qualified roofing contractor who can assess the damage, reinforce or replace compromised sections of the roof deck or rafters, and ensure the structure is sound before installing new roofing materials.

Addressing Problems Early is Key when dealing with roofing problems

For homeowners in Mt. Laurel with older properties, proactive roof maintenance is the best defense against major problems. Regular professional inspections can identify potential issues early on, allowing for targeted repairs that can extend the life of your roof and prevent more extensive damage down the line.

Ignoring signs of wear and tear or small leaks in an older roof is a gamble that rarely pays off. Water damage can spread quickly, affecting not just the roof but also insulation, interior walls, and even the structural components of your home.

Frequently Asked Questions

1. What are the signs that a roof needs to be replaced? For older homes, key signs include widespread cracking, curling, or blistering shingles, and significant loss of the protective granules, which often collect in your gutters. Inside your home, recurring leaks or water stains on the ceiling are strong indicators. A sagging roofline is a critical sign that points to potential structural issues requiring immediate professional inspection.
2. What does a worn out roof look like? A worn-out shingle roof will have shingles that look dry, brittle, or warped. You may see “bald spots” where the granules have worn away, exposing the dark asphalt layer underneath. Shingles might be cupping (edges turning up) or clawing (edges turning down), and you may notice many shingles are missing or have cracked from age and weather exposure.
3. How to tell if your roof is going to collapse? A sagging roof is the most serious visual warning sign of a potential collapse. Other indicators include cracking or splitting rafters in the attic, popping or creaking sounds coming from the roof, and interior signs like ceiling cracks, sprinkler heads dropping below the ceiling, or doors and windows that suddenly become difficult to open or close due to structural shifting. If you see these signs, evacuate and call a professional immediately.
4. How do I know if my roof is ok? The best way to know if the roof on your older home is okay is through a regular professional inspection. From the ground, you can look for obvious issues like missing shingles or granule loss in downspouts. However, an expert can safely get on the roof to assess the condition of flashing, underlayment, and ventilation, providing a complete picture of your roof’s health.
5. What is the number one cause of roof failure? While sudden storm damage can cause issues, the number one cause of roof failure, especially in older homes, is prolonged exposure to the elements leading to age-related deterioration. Over decades, sun, rain, ice, and wind wear down roofing materials, eventually compromising their ability to protect your home. Damaged or deteriorated flashing is another very common point of failure.
6. What is the average lifespan of a roof? The average lifespan for a standard asphalt shingle roof, common on many Mt. Laurel homes, is typically 20 to 30 years. The exact lifespan depends on the quality of the original materials, the installation, and how well it has been maintained over the years.
7. Are roof leaks in older homes always a sign of a bad roof? Not necessarily. A leak is a serious issue but can often be traced to a specific, repairable problem rather than total roof failure. In older homes, leaks are frequently caused by corroded, cracked, or loose flashing around chimneys, vents, and skylights. While this needs immediate attention, repairing the flashing may solve the problem without requiring a full roof replacement.
8. Why is attic ventilation a bigger problem in older homes? Many older homes were built before modern ventilation standards were established. They often lack a proper system of intake (soffit) and exhaust (ridge) vents. This traps heat and moisture in the attic, which can bake shingles from below in the summer and cause destructive ice dams in the winter, significantly shortening a roof’s lifespan.
9. Does home insurance cover roof replacement? Homeowner’s insurance typically covers roof replacement if the damage is caused by a sudden, accidental event (often called a “peril”) like a storm, fire, or falling tree. It generally does not cover replacement due to old age, wear and tear, or lack of maintenance.
10. How old may a roof be before insurance claims it’s too old? This varies by insurance provider, but many companies become hesitant to write or renew policies for homes with asphalt shingle roofs that are over 20 years old. They may require an inspection to prove the roof is in good condition or limit coverage for an older roof. It’s best to check with your specific insurance agent.
11. Can you put new shingles over old ones on an older house? While sometimes possible (if there is only one existing layer), it is generally not recommended for older homes. Adding a second layer puts extra weight on the home’s structure, which may already be compromised by age. More importantly, it prevents a roofer from inspecting the roof deck and underlayment for rot or damage, potentially trapping serious problems underneath the new shingles.
12. What is the most important first step when dealing with an old roof? The most important first step is to schedule a comprehensive professional roof inspection. An experienced roofer who understands the nuances of older homes can properly assess the condition of the shingles, flashing, underlayment, and structure. This expert diagnosis is crucial for making an informed decision about whether to repair or replace your roof.
13. Do I need a special type of roofer for my historic Mt. Laurel home? Yes, it is highly recommended. A roofer with experience in older and historic homes will understand the unique construction techniques and materials used. They can identify age-specific problems like outdated flashing or inadequate ventilation and provide solutions that protect your home’s structural integrity and historical character, which a roofer who only works on new construction might miss.
14. How much does it cost to replace a roof? The cost of a roof replacement depends on many factors, including the home’s size, the roof’s pitch or steepness, the type of shingle you choose, and whether the underlying roof deck needs repairs. For an accurate price for your Mt. Laurel home, it’s essential to get a detailed, on-site estimate from a reputable roofing contractor.
15. How long does a roof replacement take? For an average-sized home, a professional roofing crew can typically complete a full roof replacement in 2 to 4 days. The timeline can be affected by the weather, the complexity of the roof, and the extent of any necessary structural repairs discovered after the old roofing is removed.
