Watch Out for These Asphalt Shingle Issues
By Connor Levesque | 12/23/24
No matter what type of roofing material you have, keeping an eye out for potential issues is key to maintaining your home’s safety and value. For most of us that means, 3-tab shingles, specially, asphalt shingle roofs.
Asphalt shingles are a popular roofing choice because they’re affordable, durable, and versatile, but like any roof, they’re not immune to wear and tear over time. Neglecting small problems can lead to expensive roof repairs or replacement.
Let’s go over some of the most common warning signs that might mean your roof needs attention, whether it’s a minor fix or a complete overhaul.
What Are Asphalt Shingles?
Before we dive into the warning signs, let’s take a moment to understand what asphalt shingles are and why they’re so widely used. Asphalt shingles are the most common roofing material in North America because they’re cost-effective, durable, and fairly easy to install. They’re made of a fiberglass or felt base mat, which is coated in asphalt for waterproofing and topped with mineral granules for additional protection.
These shingles come in a variety of colors and styles, making them a versatile option for homeowners. On average, asphalt roofing shingles can last anywhere from 15 to 30 years, depending on the quality of the shingles, the local climate, and how well the roof is maintained. However, even the best shingles can show signs of age or damage over time.
Curling, Brittle or Buckling Shingles
One of the most obvious signs that your asphalt shingle roof needs some attention is the condition of the shingles themselves—like if they’re curling, brittle, or buckling. These issues can happen for a variety of reasons, such as the natural aging of the shingles, poor installation, or long-term exposure to extreme weather like heavy rain, snow, or intense heat.
As shingles get older, the protective granules on their surface start to wear away, which can cause the edges to curl and lift. This makes them more vulnerable to damage from strong winds and water leaks. Curling shingles are a clear sign that your roof might be nearing the end of its lifespan.
Brittle shingles, on the other hand, can easily crack or break, leaving gaps where water can sneak through. These cracks might not be obvious at first, but they can grow over time and lead to bigger problems.
Buckling shingles happen when the mat under the asphalt shrinks or warps, which can be caused by too much heat, moisture, or poor attic ventilation. When shingles buckle, they create an uneven surface that not only looks bad but also weakens your roof’s ability to protect your home.
All of these issues—curling, brittle, and buckling shingles—can lead to serious water problems. If water gets through your roof, it can cause expensive damage to your home’s structure, like rotting wood, mold, and ruined insulation. If these problems aren’t dealt with quickly, they can spiral into even bigger issues, both inside and outside your home.
Missing or Damaged Shingles
Missing or cracked shingles are another major red flag that homeowners shouldn’t ignore. High winds, heavy rain, hail, or falling debris can knock shingles loose or cause visible damage that compromises the integrity of your roof. Missing shingles leave your roof exposed to the elements, increasing the risk of water infiltration, which can damage the underlying structure and lead to costly repairs if not addressed quickly.
While asphalt shingles are wind and impact resistant, they are not invincible. Damaged shingles, whether they’re cracked, split, curled, or torn, are equally problematic and can allow moisture to seep into your roof system over time. If you notice missing or damaged shingles, it’s crucial to act promptly and have them replaced as soon as possible.
Ignoring the issue could lead to serious consequences, such as water leaks that damage ceilings and walls, mold growth caused by trapped moisture, and even expensive structural problems like rotting wood or weakened support beams. Regularly inspecting your roof and addressing these issues early on will help you maintain the durability of your home and avoid unnecessary repair costs down the road.
Granule Loss (Degranulation)
The granules on asphalt shingles aren’t just for looks—they play a critical role in protecting your roof from UV rays, heat, and the elements. Over time, these granules can wear off due to weathering, physical impact, or age. If you start noticing a lot of granules in your gutters, around your downspouts, or scattered near your home, it’s a warning sign that your shingles are deteriorating.
Granule loss can compromise the effectiveness of your roof, leaving it more vulnerable to sun damage and leaks. Granule loss is a common sign that shingles are nearing the end of their lifespan, so it might be “replacing your roof” time.
Water Stains or Leaks
Water stains on your ceiling or walls are one of the clearest and most common signs of a potential problem with your roof. These stains often indicate a leak, which can result from several issues such as broken or missing shingles, damaged flashing around vents or chimneys, clogged gutters that prevent proper water drainage, or even an ice dam forming along the roof edge during winter. Each of these problems, if not addressed, can worsen over time, leading to more extensive damage.
Leaks, no matter how small or seemingly insignificant, should never be ignored. Even minor water intrusion can create the perfect conditions for problems like wood rot, the growth of dangerous mold, and damage to your home’s structural integrity. Over time, what starts as a small leak can escalate into costly repairs, including replacing insulation, drywall, or even parts of your roof.
To prevent larger and far more expensive issues, be proactive about addressing any leaks. Regular roof inspections, clearing out your gutters, and promptly repairing damaged roof components can save you a significant amount of trouble in the long run. A little maintenance today can prevent major headaches tomorrow.
Discoloration or Algae Growth
Have you noticed dark streaks or stains on your shingles? These unsightly marks are often caused by algae growth, especially if your home is located in a humid or shaded area. Algae isn’t particularly harmful to the shingles themselves, but it can be a warning sign of underlying issues, such as excess moisture or poor ventilation in your attic. Left unchecked, these conditions may contribute to further problems over time, like the buildup of mold or mildew inside your home.
Algae, moss, or mold growth on your roof can also trap moisture against the shingles, creating an environment that accelerates wear and tear. This can lead to premature deterioration of your roofing materials, reducing their lifespan and potentially causing leaks or structural damage.
Fortunately, regular roof cleaning, proper maintenance, and ensuring adequate attic ventilation can help mitigate algae growth, prevent moisture buildup, and protect your roof from unnecessary damage. Taking these steps not only improves the appearance of your roof but also ensures it remains strong and durable for years to come.
Are Shingles Covered by Warranty or Homeowners Insurance?
Shingle warranties are designed to cover defects in materials or workmanship, addressing issues caused by manufacturing flaws through repair or replacement of the faulty shingles. These warranties provide homeowners with peace of mind, acting as a safeguard against problems stemming from production errors. However, it’s crucial to understand their limitations. Most warranties exclude damages caused by external factors such as severe weather, improper installation, or poor maintenance. Reviewing the specific terms and conditions is essential to know exactly what is and isn’t covered.
In contrast, homeowners insurance typically protects against damage resulting from specific events like windstorms, hail, or natural disasters. However, it’s important to note the exclusions, such as general wear and tear or damage due to improper installation, which are rarely covered. To keep your insurance policy valid, regular roof maintenance, including inspections and timely repairs, is often required.
The coverage offered by both warranties and insurance can vary significantly depending on their terms, making it vital to carefully review the fine print. If your shingles are damaged, act quickly—take detailed photos, document the issue thoroughly, and notify your insurance provider right away to initiate the claims process. Prompt action not only helps ensure a smoother resolution but also prevents further damage to your roof.
What to Do If You Spot Any of These Signs
If you notice any of these warning signs on your asphalt shingle roof, don’t wait to take action. Depending on the severity of the problem, you may need a roofing contractor for a roof inspection to determine whether repairs will suffice or if a full replacement is needed. Regular maintenance, such as cleaning gutters, inspecting shingles, and addressing small issues early, can go a long way in extending the lifespan of your roof.
Remember, investing in timely repairs now can save you from costly repairs or replacements later. A well-maintained roof not only protects your home but also preserves its value, giving you peace of mind for years to come.
