If you're a homeowner in the vibrant city of New Orleans, you know that your roof is your home's first line of defense against the city's dynamic weather. Maintaining the integrity of your roof is paramount, and this includes understanding why shingles, the frontline soldiers of your roofing system, may fall off. In this comprehensive guide from Roof Squad, your trusted New Orleans roofing contractor, we will delve into the top four reasons why shingles might fall off your roof. From the impact of weather conditions to installation issues, aging and wear, and the overlooked factor of insufficient attic ventilation, we aim to provide you with the knowledge to make informed decisions about your roof. We'll also discuss the advantages of quality roofing materials like Owens Corning shingles and the value a Platinum Preferred Contractor brings to your roofing project. So, let's get started and unravel the mystery of falling shingles.

Weather Conditions and the Importance of Quality Materials

A good roofing job stands the test of time and weather without putting your home at risk

A primary factor influencing the longevity of your shingles is New Orleans' unique weather. As locals, we understand the city's diverse climate, from blistering summer heat to powerful storms during hurricane season. These extreme weather conditions can damage your roof, causing shingles to crack, blister, or even get blown away.

As a homeowner, you might wonder, "How can I protect my roof from this harsh weather?" The answer lies in selecting high-quality roofing materials designed to withstand such conditions. One such product is Owens Corning shingles.

Owens Corning's line of shingles are made with SureNail® Technology, a unique feature that provides outstanding grip, exceptional wind resistance, and incredible durability. This technology gives the shingles a high degree of resistance to the pull-through and wind uplift, making them a perfect choice for New Orleans homes.

Regular maintenance and inspection from a Platinum Preferred Contractor like Roof Squad also play a vital role in safeguarding your roof from weather damage. This is specially important when you are preparing yourself for the storm season to begin.

The Impact of Poor Installation on Your Roof

The best materials in won't protect your home if they are nor properly installed.

Unfortunately, even the best shingles won't protect your home if they're poorly installed. A faulty installation can lead to various problems, including shingles falling off your roof prematurely. In many cases, it's not the materials, but the installation that fails. At Roof Squad we pride ourselves in having strict quality control processes that ensure a top notch roof replacement or installation that will last for years to come.

Incorrect Nailing

One common mistake during the installation process is incorrect nailing. Shingles require accurate nailing to secure them firmly onto the roof deck. This means using the right number of nails, correctly placed, and driven straight in. If the shingles are under-nailed, over-nailed, or the nails are driven in at an angle or driven too deep, it can lead to loose shingles, making them susceptible to blowing off in high winds.

Poor Shingle Alignment

Another crucial aspect of shingle installation is correct alignment. The shingles should be straight and consistent to effectively shed water and withstand wind. Misaligned shingles can create gaps where wind can get underneath, potentially lifting the shingle and leading to leaks or even shingle loss.

Inadequate Sealing

Shingles come with a sealing strip that bonds them together, creating a single, cohesive roof covering. If the shingles are not properly aligned or the roof surface is not adequately cleaned before installation, the sealing strip may not adhere correctly. This can lead to shingles failing to seal, making them prone to wind uplift and water intrusion.

Improper Flashing Installation

Flashing is essential in areas where the roof meets a vertical wall, around roof protrusions such as vents, and in valleys. If the flashing is not properly installed, water can seep under the shingles, leading to leaks and potentially causing shingles to loosen over time.

Not Accounting for Roof Ventilation

Proper roof ventilation is crucial for maintaining a consistent temperature across the roof, preventing hotspots that can warp shingles and make them brittle. If ventilation isn't correctly addressed during the roof installation process, it can lead to heat damage and shingle loss.

That's where choosing a reliable and certified contractor comes in. As an Owens Corning Platinum Preferred Contractor, Roof Squad adheres to the highest installation standards. We undergo regular training and follow specific guidelines to ensure we deliver quality roofing services.

Our status as a Platinum Preferred Contractor also allows us to offer extended warranties on Owens Corning products, giving you additional peace of mind.

Age and Wear: How Time Impacts Your Shingles

If your roof is more than 5 years old, make sure to get a proper inspection done.

Even the best-maintained roofs have a lifespan. Over time, shingles start to show signs of wear and tear, like curling, cracking, or granule loss. These age-related issues make shingles more susceptible to wind uplift and can eventually lead to them falling off your roof.

Granule Loss

Roofing shingles are covered in granules, which are tiny bits of ceramic-coated minerals. These granules provide multiple functions: they protect the asphalt layer from UV rays, provide fire resistance, and contribute to the aesthetic look of the roof. As your roof ages, these granules can be gradually washed off or blown away, leaving the shingle exposed. The exposed asphalt layer can then dry out and become brittle, increasing the chance of cracks and eventually leading to shingle loss.

Shingle Curling

Over time, shingles can start to curl, either cupping (edges turning upward) or clawing (middle raising, and the edges remain flat). Curling can happen due to several reasons: poor attic ventilation causing uneven heat distribution, a defective product, or simply the roof's age. Curled shingles can easily be lifted by the wind and are more likely to break and fall off.

Cracks Formation

As shingles age and lose their flexibility, they can start to crack. Extreme temperature changes can exacerbate this process as the shingles expand and contract. Cracked shingles have a higher chance of being blown off by strong winds and can also allow water to seep through, leading to further damage.

Sealant Deterioration

Roofing shingles are sealed together with a roofing sealant that helps prevent wind uplift and water penetration. Over time, the sealant can deteriorate, losing its adhesive qualities. As a result, the bond between shingles weakens, making them more likely to be lifted and blown off by the wind.

Deck Movement

The deck, or sheathing, is the base on which the shingles are installed. Changes in temperature and humidity can cause the deck to expand and contract over time, leading to movement. This movement can cause nails to back out, loosening shingles and making them susceptible to wind damage and falling off.

Here again, Owens Corning's innovations come into play. Their shingles are manufactured using advanced techniques that ensure superior longevity. TruDefinition® Duration® shingles, for example, are specially formulated to provide dramatic color contrast and dimension to any roof. These shingles are not only stunning but also come with a Limited Lifetime Warranty*, a testament to their longevity.

Understanding the Role of Insufficient Attic Ventilation in Shingle Loss

Proper ventilation will save you lots of headaches down the line

Proper attic ventilation is a critical, yet often overlooked, aspect of roof health and longevity. Without adequate ventilation, your roof may be at risk of several problems, including the premature loss of shingles. Let's delve deeper into how this works.


A well-ventilated attic ensures a steady flow of air through the underside of your roof, helping to regulate the roof's temperature. Without sufficient ventilation, heat can become trapped in the attic during the hot summer months, significantly raising the temperature of your roof. This excess heat can cause shingles to overheat, leading to thermal splitting or cracking. Over time, these weakened shingles can lose their adhesion and may blow off in windy conditions.

Moisture Build-Up

Insufficient attic ventilation can also lead to moisture build-up in your attic. The warm air that gets trapped in your attic can cause condensation, especially in cooler weather. This condensation can cause moisture to accumulate under your shingles, causing them to warp, buckle, or become loose. Over time, these affected shingles can deteriorate faster and may eventually fall off.

Ice Damming

In colder climates, poor attic ventilation can lead to a phenomenon known as ice damming. While not common in New Orleans, it's worth understanding as it shows the importance of attic ventilation. Ice dams occur when heat from inside your home causes snow on your roof to melt. The melted snow then refreezes at the edge of your roof, causing an "ice dam." This dam can force water underneath your shingles, damaging them and potentially causing them to loosen or fall off.

Impact on Shingle Warranty

Another factor to consider is the impact of poor ventilation on your shingle warranty. Many shingle manufacturers, including Owens Corning, stipulate that adequate ventilation is a requirement for their warranties to remain valid. This means if you have poor attic ventilation and experience shingle loss, your warranty may not cover the repairs.

Owens Corning and Roof Squad understand the importance of a comprehensive roofing system. A complete roofing system includes not only quality shingles but also balanced attic ventilation. This balanced ventilation extends the life of your roof and helps prevent issues like heat buildup and ice damming.
