Asphalt shingles stand as the unrivaled champions of residential roofing, and it’s no wonder why. Not only do they offer a budget-friendly solution, but they seamlessly blend with the traditional aesthetic of countless neighborhoods.

Despite their popularity, it’s crucial to acknowledge that asphalt shingles aren’t immune to issues. Throughout the lifespan of your roof, you might encounter some common challenges associated with this material.

To safeguard against potential headaches, it’s imperative to familiarize yourself with these issues. By staying informed, you’ll be well-equipped to identify any problems promptly and prevent them from escalating into costly repairs.

So, before you make your purchasing decision, let’s go through the top six asphalt shingle roofing problems to look out for.


Shingle Problem #1: Blistering

Blistering ranks high among the typical asphalt shingle problems that prompt homeowners to seek professional assistance. It occurs when moisture trapped within the shingle expands, rupturing the surface and leaving it vulnerable. This issue predominantly arises during the scorching summer months.

Understanding the root causes of blistering is paramount. Moisture infiltration during the shingle manufacturing process stands as one significant origin. Shingles usually comprise three primary layers: a fiberglass base, an asphalt coating, and a granule layer on top. If moisture infiltrates any of these layers during manufacturing, the likelihood of blistering increases.

Inadequate roof ventilation also contributes to blistering by trapping moisture. Poor ventilation is a notorious culprit behind various shingle roofing problems, underscoring the importance of ensuring proper airflow during shingle installation.

Blistering compromises the integrity of your roof, decking, and property, paving the way for leaks and premature roof system failure. Timely intervention is crucial to prevent further damage. While blistering may resemble hail damage at times, seasoned contractors or roofing repair professionals can discern between the two and recommend the most suitable solution.

Shingle Problem #2: Curling

When it comes to asphalt shingle roofing, curling is a common issue that demands attention. Imagine glancing up at your roof and noticing the edges of the shingles peeling away or the corners turning upward – that’s curling in action.

Causes of Curling:

  • Age: As shingles approach the end of their lifespan, they tend to shrink and curl, signaling the need for a roof replacement. 
  • Improper Installation: Incorrect installation practices such as misalignment during installation or roofing over uneven surfaces without proper preparation can result in curling. 
  • Ventilation Problems: Poor ventilation can lead to trapped moisture, which in turn can cause shingles to curl. 
  • Thermal Shock: One common culprit behind shingle curling is thermal shock. This occurs when the roof experiences sudden temperature fluctuations, such as a rapid cooldown after a warm day. Repeated thermal shocks can induce curling over time.

Impact of Curling:

Similar to blistering, curling can pave the way for leaks and overall roof failure if neglected. Once you observe signs of curling, it’s crucial to address the issue promptly through repairs or consider investing in a new roof altogether.

By understanding the causes and consequences of shingle curling, homeowners can take proactive steps to safeguard their roofing investment. Don’t let curling compromise the integrity of your roof – take action now to ensure its longevity and durability.

Shingle Problem #3: Cracking Concerns

Hey there, roof-watchers! Today, let’s tackle another crucial aspect of shingle health: cracking. It’s like the wrinkles of your roof’s skin, revealing signs of aging and potential problems lurking beneath the surface.

Cracking on shingles isn’t uncommon, especially as they weather the elements year after year. Wind, temperature shifts, and even the occasional rooftop dance party (just kidding!) can contribute to this natural wear and tear.

Now, if your roof has a few cracks here and there, and it’s been around the block a few times, it’s probably just showing its age. However, if you’ve recently had a new roof installed or notice premature cracking, it’s time to put on your detective hat.

Premature cracking could signal issues during installation, a defective batch of shingles, or poor ventilation in your roof setup. These issues need swift attention to prevent bigger headaches down the road.

Remember, cracked shingles aren’t just cosmetic annoyances; they can compromise your roof’s ability to keep the elements at bay. So, keep an eye out, and when in doubt, call in the experts to nip the problem in the bud!

Shingle Problem #4: Granule Loss

Granule loss might seem like just another headache for your shingle roof, but understanding its causes and effects is crucial for keeping your home safe and secure.

Let’s break it down: those tiny granules on your shingles aren’t just for show. They’re like armor, protecting your roof from the elements and extending its lifespan. But over time, they can start to break away, leaving your roof vulnerable.

Why does this happen? Well, there are a few potential culprits:

  • Uneven application of asphalt during manufacturing can lead to poor adhesion, causing granules to detach. 
  • If your roof gets too hot, the asphalt can melt, taking granules with it. 
  • Poor ventilation in your attic can create a host of problems, including granule loss.

If you’re noticing a lot of granules in your gutters or bald spots on your roof, it’s time to take action. Ignoring the issue can lead to clogged gutters, UV damage, leaks, and even roof failure.

So, what can you do? Start by inspecting your roof regularly and addressing any issues promptly. Consider improving ventilation in your attic to prevent future problems. And if you’re not sure what’s causing the granule loss, don’t hesitate to call in the professionals for help.

Shingle Problem #5: Mold, Mildew, & Algae

Now, most of the time, these black streaks are just surface-level nuisances. But if you’re not a fan of the look or worried about potential damage, there are solutions. Consider investing in anti-algae shingles like GAF’s StainGuard Plus™, packed with copper and zinc ions to deter growth.

But here’s the kicker: if left unchecked, these organic invaders can lead to moisture buildup. And trust me, trapped moisture spells bad news for your roof’s underlayment, possibly even causing rot in the plywood or OSB deck.

So, while mold, mildew, and algae might seem like minor annoyances, it’s crucial to take action before they escalate into bigger problems. Stay vigilant, my friends!

Shingle Problem #6: Missing Shingles

Let’s talk about a common roofing woe that often gets overlooked: missing shingles. Yep, those pesky little pieces can sometimes go MIA, leaving your roof vulnerable to the elements. But fear not! I’m here to shed some light on why this happens and what you can do about it.

So, why do shingles decide to take a solo trip off your roof? Well, there are a few reasons:

  • Blustery Winds: Picture a strong gust of wind playing tug-of-war with your shingles. Sometimes, it wins, lifting the edge of a shingle and setting it free. 
  • Unwanted Encounters: Your roof might have had an unexpected run-in with a falling branch or some other object, causing a shingle to bid adieu. 
  • Seal Snags: That black strip in the middle of your shingle? It’s not just for looks. It’s supposed to keep things snug. But if it’s broken or brittle, well, adhesion becomes a bit of a challenge. 
  • Temperature Troubles: Installing shingles when it’s too cold can be a recipe for disaster. If the seal doesn’t get a chance to properly engage, it’s like trying to stick two magnets together with butter—just not happening. 
  • Initial Neglect: Sometimes, the seal never even got a chance to do its job properly in the first place.

Now, here’s the important part: When you notice a shingle has gone AWOL, don’t procrastinate! Get it fixed pronto. Ignoring the issue can lead to all sorts of trouble, like water damage creeping into your cozy abode or bustling business. Trust me, you don’t want that headache.

Additional Asphalt Shingle Roof Issues to Watch Out For

Installation Error

Among the six common issues with shingle roofs mentioned earlier, many stem from an installation error, particularly on newer roofs. It’s evident that proper ventilation plays a pivotal role in roof health, a task entrusted to the contractor.

Regrettably, some contractors lack the necessary qualifications or experience. Hence, the process of selecting the right contractor becomes paramount.

To ensure a contractor’s reliability, consider the following:

  • Credentials: Confirm they are licensed, insured, and in good standing with the building department. 
  • Communication: Evaluate their responsiveness and willingness to address your queries. 
  • Transparency: Seek detailed explanations regarding available products and installation procedures. 
  • Recommendations: Rely on referrals from trusted sources like family, friends, or neighbors. 
  • Online Reviews: Explore feedback on platforms like HomeAdvisor or Angie’s List. 
  • Manufacturer Referrals: Contact shingle manufacturers for local installer recommendations.


Alright, let’s cut to the chase. Asphalt shingle roof warranties? They’re like puzzles wrapped in enigmas. Seriously, these warranties can be as complex as a Rubik’s Cube. And here’s the kicker: shingles, well, they’re not exactly the cream of the crop when it comes to roofing materials. So, naturally, the warranties tagged along with your shingle roof installation tend to be, well, lackluster at best and downright misleading at worst. Yikes!

Now, picture this: you’ve got your brand-spanking-new shingle roof, and you’re feeling pretty good about it. But wait, there’s a catch. Those warranties? They’re often prorated. Translation: sure, they’ll cover some of the repair or replacement costs, but here’s the kicker – that coverage dwindles over time. So, what does that mean for you? It means you might end up with just a tiny slice of coverage, leaving you to foot most of the bill for repairs. Talk about a financial headache!

So, what’s a savvy homeowner like yourself to do? Simple. Arm yourself with knowledge. Dive headfirst into those warranty documents – yes, I know, not the most thrilling read, but trust me, it’s worth it. Scope out what’s covered, what’s not, and all those nitty-gritty details. Whether it’s the shingle manufacturer or your trusty contractor handing out the warranty, make sure you’re crystal clear on what to expect if things hit the fan.

Manufacturer Defects 

As a homeowner or property manager, facing roofing problems can be a daunting task. One crucial aspect often overlooked is the possibility of manufacturer defects in the shingles. Let’s delve into this issue and shed light on how to identify and address it effectively.

  • Understanding Manufacturer Defects: It’s essential to recognize that some roofing issues may stem from flaws in the manufacturing process. However, pinpointing these defects can be a challenge, as manufacturers may hesitate to acknowledge them outright. 
  • Taking Action: If you suspect that your shingles are exhibiting signs of a defect, proactive steps are necessary. Initiate a dialogue with the manufacturer to discuss your concerns. They may dispatch a representative to assess the situation firsthand, distinguishing between environmental factors and genuine manufacturing flaws. 
  • Simplifying the Process: Navigating the complexities of manufacturer defects can seem overwhelming, but simplifying the approach is key. By reaching out to the manufacturer and facilitating an inspection, you can gain clarity on the root cause of the issue, paving the way for prompt resolution.
